• Sencha touch 2/ app workflow with navigation view

  - by eplatonov

  I am trying to understand how can I implement the same functionality which provides navigation view in sencha touch 2, but .... Each item of the 'Ext.NavigationView' component should have it's own unique set of 'navigationBar' elements. I mean set of buttons, for example. I know that I can do something like this: this.getMain().getNavigationBar().rightBox.removeAll(); this.getMain().getNavigationBar().rightBox.add(this.getSettingButton()); //where 'getSettingButton' predefined by me a button And do this action each time when 'push' event happens (clear 'navigationBar' and add appropriate set of buttons) Of course, I even can implement 'Ext.Panel' with 'layout: card' and set of 'Ext.panel' elements in the 'items' property, each of which will be have unique 'toolbar'. To control the behavior I can use 'setActiveItem' method. But, I think each of these approaches is a bit weird, isn't it? I expected that would be much more natural approach to implement it. Most likely I don't know what I need. Confirm my doubts. What is the best way to do it.

• Bing Map on Windows Phone - add click events to pushpins; display more details

  - by Will Gill

  I have a WP Phone app using a Bing Map control. I have an array of objects, and each object has a location. I iterate the array to place the pins on the map (see below). I have a touch event bound to each pin to allow the user to tap the pin to start an action. Now - I would like, on tap, to show information from the object that relates to that pin to be shown in a textbox. How can I retrieve the object from the array that corresponds to the pushpin that was tapped/clicked? foreach (wikiResult result in arrayResults) { double lat = double.Parse(result.Latitude, CultureInfo.InvariantCulture); double lng = double.Parse(result.Longitude, CultureInfo.InvariantCulture); statusTextBlock.Text = result.Latitude + " " + result.Longitude + " " + lat + " " + lng; GeoCoordinate d = new GeoCoordinate(lat, lng); Pushpin pin; pin = new Pushpin(); pin.Location = d; pin.Content = result.Name; pin.MouseLeftButtonUp += new MouseButtonEventHandler(pin1_MouseLeftButtonUp); myMap.Children.Add(pin); } void pin1_MouseLeftButtonUp(object sender, MouseButtonEventArgs e) { //display the content from the object in a text box } Many thanks in advance!

• iPhone SDK allow touches to affect multiple views

  - by Parad0x13

  I have a main view that has has two buttons on it that control methods to display the next image and display the previous image. In this case the 'Image' is a class that inherits from UIImageView and has multiple pictures on it that you can interact with, and I call this class a 'Pane'. The pane itself handles all the user interaction itself while the main view controls the display of next and previous panes with the buttons. Here is my dilemma, because the pane fully covers the main view it wont allow for the user to tap the buttons on the main view! So once a pane pops up you cannot change it via the buttons! Is there a way to allow touches through transparent parts of a view, or if not how in the world do I achieve this?! I cannot pass touchesBegan or any of those methods from the pane to the superview because all of the button touch methods are created in the xib file. I cannot insert the pane under the control panel because then you wouldn't be able to interact with the pane. And as far as I know theres no way to pass touch events to every single pane within the paneHoldingArray that belongs to the main view I cannot add the command buttons inside of the pane because I want to be able to replace the command button's image with a thumbprint render of the next/previous pane. I've been stuck on this for a very long time, please somebody help me out with a fix action or a new way to re-engineer the code so that it will work!

• Error while updating Database record with Entity Framework on ASP.NET MVC Page

  - by Rupa

  Hi I have an ASP.NET Page that updates registered User Address Details for a selected record. Below is the Update method that i am calling from Controller. When i am calling ApplyPropertyChanges method, I am getting the below error. Did anyone run into the same error while updating the record with Entity Framework. Appreciate your responses. Error Message: The existing object in the ObjectContext is in the Added state. Changes can only be applied when the existing object is in an unchanged or modified state. My Update Method Code: [HttpPost] public bool UpdateAddressDetail([Bind(Prefix = "RegUser")] AddressDetail regUserAddress, FormCollection formData) { regUserAddress.AD_Id = 3; regUserAddress.LastUpdated = HttpContext.User.Identity.Name; regUserAddress.UpdatedOn = DateTime.Now; regUserAddress.AddressType = ((AddressDetail)Session["CurrentAddress"]).AddressType ??

• Business entity: private instance VS single instance

  - by taoufik

  Suppose my WinForms application has a business entity Order, the entity is used in multiple views, each view handles a different domain or use-case in the application. As an example, one managing orders, the other one digging into one order and displaying additional data. If I'd use nHibernate (or any other ORM) and use one session/dataContext per view (or per db action), I'd end up getting two different instances for the same Order (let's say orderId = 1). Although functionally the same entity, they are technically two different instances. Yes, I could implement Equals/GetHashcode to make them "seem" the same. Why would you go for a single instance per entity vs private instances per view or per use-case? Having single instances has the advantage of sharing INotifyPropertyChanged events, and sharing additional (non-persistent) data. Having a private instance in each view would give you the flexibility of the undo functionality on a view level. In the example above, I'd allow the user to change order details, and give them the flexibility to not save the change. Here, synchronisation between the view/use-case happens on a data persistence level. What would your argument be?

• An Interactive Console I/O Wrapper/Interceptor in C# - What is the issue?

  - by amazedsaint

  I was trying to put together an interactive Console interceptor/wrapper in C# over the weekend, by re-mixing few code samples I've found in SO and other sites. With what I've as of now, I'm unable to read back from the console reliably. Any quick pointers? public class ConsoleInterceptor { Process _interProc; public event Action<string> OutputReceivedEvent; public ConsoleInterceptor() { _interProc = new Process(); _interProc.StartInfo = new ProcessStartInfo("cmd"); InitializeInterpreter(); } public ConsoleInterceptor(string command) { _interProc = new Process(); _interProc.StartInfo = new ProcessStartInfo(command); InitializeInterpreter(); } public Process InterProc { get { return _interProc; } } private void InitializeInterpreter() { InterProc.StartInfo.RedirectStandardInput = true; InterProc.StartInfo.RedirectStandardOutput = true; InterProc.StartInfo.RedirectStandardError = true; InterProc.StartInfo.CreateNoWindow = true; InterProc.StartInfo.UseShellExecute = false; InterProc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden; bool started = InterProc.Start(); Redirect(InterProc.StandardOutput); Redirect(InterProc.StandardError); } private void Redirect(StreamReader input) { new Thread((a) => { var buffer = new char[1]; while (true) { if (input.Read(buffer, 0, 1) > 0) OutputReceived(new string(buffer)); }; }).Start(); } private void OutputReceived(string text) { if (OutputReceivedEvent != null) OutputReceivedEvent(text); } public void Input(string input) { InterProc.StandardInput.WriteLine(input); InterProc.StandardInput.Flush(); } }

• Backdoor in OpenBSD how is it that no developer saw it ? And what about other Linux ? [closed]

  - by user310291

  It had been revealed that there have been backdoor implanted in OpenBSD http://www.infoworld.com/d/developer-world/software-security-honesty-the-best-policy-285 OpenBSD is opensource, how is it that nobody in the community developper could see it in the source code ? So how can one trust all the other "opensource" Linux Of course OpenBSD is only a case, the point is not about OpenBSD, it is about opensource in general. my question is not about Openbsd per se it's about source code os inspection especially c/c++ since most are written in these languages. Also once the source is compiled how one can be sure that it really reflects the source code ? If a law requires that a backdoor being implanted and obliges to deny that kind of action under the guise of security, how can you be sure that the system has not been corrupted by some tools ? As said there is there is a "nondisclosure agreement" My guess is that 99.99% of developpers in the world are just incapable of understanding os source code and won't even bother to look at it. And above all nobody wonders about why the gov wants such massive backdoor, and that of course they will pressure medias to deny.

• Rails' page caching vs. HTTP reverse proxy caches

  - by John Topley

  I've been catching up with the Scaling Rails screencasts. In episode 11 which covers advanced HTTP caching (using reverse proxy caches such as Varnish and Squid etc.), they recommend only considering using a reverse proxy cache once you've already exhausted the possibilities of page, action and fragment caching within your Rails application (as well as memcached etc. but that's not relevant to this question). What I can't quite understand is how using an HTTP reverse proxy cache can provide a performance boost for an application that already uses page caching. To simplify matters, let's assume that I'm talking about a single host here. This is my understanding of how both techniques work (maybe I'm wrong): With page caching the Rails process is hit initially and then generates a static HTML file that is served directly by the Web server for subsequent requests, for as long as the cache for that request is valid. If the cache has expired then Rails is hit again and the static file is regenerated with the updated content ready for the next request With an HTTP reverse proxy cache the Rails process is hit when the proxy needs to determine whether the content is stale or not. This is done using various HTTP headers such as ETag, Last-Modified etc. If the content is fresh then Rails responds to the proxy with an HTTP 304 Not Modified and the proxy serves its cached content to the browser, or even better, responds with its own HTTP 304. If the content is stale then Rails serves the updated content to the proxy which caches it and then serves it to the browser If my understanding is correct, then doesn't page caching result in less hits to the Rails process? There isn't all that back and forth to determine if the content is stale, meaning better performance than reverse proxy caching. Why might you use both techniques in conjunction?

• ant ftp task "Could not date test remote file"

  - by avok00

  Hi guys! I am using Ant ftp task to deploy my project files to a remote app server. Ant is not able to detect the date of the remote file and it re-uploads all files every time. When I start Ant in debug mode it says: [ftp] checking date for mailer.war [ftp] Could not date test remote file: mailer.war assuming out of date. The remote server is MS FTP (Windows Vista version) Ant version is 1.8.2; I use commons-net-2.2 and jakarta-oro-2.0.8 (could not find newer version) My ant task looks like this <!-- Deploy new and changed files --> <target name="deploy" depends="package" description="Deploy new and changed files"> <ftp server="localhost" userid="" password="" action="send" depends="yes" passive="true" systemTypeKey="WINDOWS" serverTimeZoneConfig="Europe/Sofia" defaultDateFormatConfig="MMM dd yyyy" recentDateFormatConfig="MMM dd HH:mm" binary="true" retriesAllowed="3" verbose="true"> <fileset dir="${webapp.artefacts.path}"/> </ftp> </target> I read an article here: Ant:The definitive guide that says I need a version of jakarta oro AFTER 2.0.8 to talk to MS FTP servers, but I was not able to find such version. Jakarta oro site - http://jakarta.apache.org/oro/ says the oro project is retired as of 2010, but their latest distribution is from 2003! Please, can anyone help me with this? Any solution or any alternatives to the Ant ftp task? Thanks!

• How do I use this indirect relationship?

  - by tyjkenn

  I'm working on incorporating a reputation system into my site, similar to SO. Here is how it is structured: User hasMany Project User hasMany Answer Project hasMany Rating Answer hasMany Rating Rating belongsTo Project where Rating.parent_type = Project Rating belongsTo Answer where Rating.parent_type = Answer Rating's value field will be a number between 1 and 5. The user should gain +10 for every 5-star review, +5 for every 4-star review, and +1 for every 3-star review. The way I currently have it set up is this: a recalcRep($id) action in the UsersController (along with other actions in other controllers, when necessary) calls the calcRep($id) method inside the User model, which is supposed to calculate the reputation of a user with an id of $id. public function calcRep($id) { $rep = 0; $data = $this->Rating->find('all'); //does not work, because it is not directly associated foreach($data as $rating) { if(($rating['Rating']['parent_type'] == 'Project' && $rating['Project']['user_id']==$id) or ($rating['Rating']['parent_type'] == 'Answer' && $rating['Answer']['user_id']==$id)) { if($rating['Rating']['value']==5) { $rep += 10; } else if($rating['Rating']['value']==4) { $rep += 5; } else if($rating['Rating']['value']==3) { $rep += 2; } } } $data['User']['reputation'] = $rep; $this->save($data); } I may be approaching this in completely the wrong way, but I can't figure out how to find all the ratings that belong to any of the children of a specific user.

• should variable be released or not? iphone-sdk

  - by psebos

  Hi, In the following piece of code (from a book) data is an NSDictionary *data; defined in the header (no property). In the viewDidLoad of the controller the following occurs: - (void)viewDidLoad { [super viewDidLoad]; NSArray *keys = [NSArray arrayWithObjects:@"home", @"work", nil]; NSArray *homeDVDs = [NSArray arrayWithObjects:@"Thomas the Builder", nil]; NSArray *workDVDs = [NSArray arrayWithObjects:@"Intro to Blender", nil]; NSArray *values = [NSArray arrayWithObjects:homeDVDs, workDVDs, nil]; data = [[NSDictionary alloc] initWithObjects:values forKeys:keys]; } Since I am really new to objective-c can someone explain to me why I do not have to retain the variables keys,homeDVDs,workDVDs and values prior exiting the function? I would expect prior the data allocation something like: [keys retain]; [homeDVDs retain]; [workDVDs retain]; [values retain]; or not? Does InitWithObjects copies (recursively) all objects into a new table? Assuming we did not have the last line (data allocation) should we release all the NSArrays prior exiting the function (or we could safely assumed that all NSArrays will be autoreleased since there is no alloc for each one?) Thanks!!!!

• Adding figures using contextual menu - Eclipse GEF

  - by darkie15

  All, I am creating a palette less eclipse plugin where am adding figures to the custom editor through the contextual menu, but am not finding a way to do it. Can anyone please guide me as to how to go about adding figures to editor dynamically through context menu i.e. adding actions/commands. Since Eclipse GEF plugin development finds so less examples to look at, I am adding my solution so others find it useful. This code helps to render a node to the editor. Source code for Action class to render figures to the editor: public class AddNodeAction extends EditorPartAction { public static final String ADD_NODE = "ADDNODE"; public AddNodeAction(IEditorPart editor) { super(editor); setText("Add a Node"); setId(ADD_NODE); // Important to set ID } public void run() { <ParentModelClass> parent= (<ParentModelClass>)getEditorPart().getAdapter(<ParentModelClass>.class); if (parent== null) return; CommandStack command = (CommandStack)getEditorPart().getAdapter(CommandStack.class); if (command != null) { CompoundCommand totalCmd = new CompoundCommand(); <ChildModelToRenderFigureCommand>cmd = new <ChildModelToRenderFigureCommand>(parent); cmd.setParent(parent); <ChildModelClass> newNode = new <ChildModelClass>(); cmd.setNode(newNode); cmd.setLocation(getLocation()); // Any location you wish to set to totalCmd.add(cmd); command.execute(totalCmd); } } @Override protected boolean calculateEnabled() { return true; } }

• Symfony dynamic forms

  - by Asier

  Hi there, I started with a form, which is made by hand because of it's complexity (it's a javascript modified form, with sortable parts, etc). The problem is that now I need to do the validation, and it's a total mess to do it from scratch in the action using the sfValidator* classes. So, I am thinking to do it using sfForm so that my form validation and error handling can be done more easier and so I can reuse this form for the Edit and Create pages. The form is something like this: <form> <input name="form[year]"/> <textarea name="form[description]"></textarea> <div class="sortable"> <div class="item"> <input name="form[items][0][name]"/> <input name="form[items][0][age]"/> </div> <div class="item"> <input name="form[items][1][name]"/> <input name="form[items][1][age]"/> </div> </div> </form> The thing is that the sortable part of the form can be expanded from 2 to N elements on the client side. So that it has variable items quantity which can be reordered. How can I approach this problem? Any ideas are welcome, thank you. :)

• Model binding & derived model classes

  - by Richard Ev

  Does ASP.NET MVC offer any simple way to get model binding to work when you have model classes that inherit from others? In my scenario I have a View that is strongly typed to List<Person>. I have a couple of classes that inherit from Person, namely PersonTypeOne and PersonTypeTwo. I have three strongly typed partial views with names that match these class names (and render form elements for the properties of their respective models). This means that in my main View I can have the following code: <% for(int i = 0; i < Model.Count; i++) { Html.RenderPartial(Model[i].GetType().Name, Model[i]); } %> This works well, apart from when the user submits the form the relevant controller action method just gets a List<Person>, rather than a list of Person, PersonTypeOne and PersonTypeTwo. This is pretty much as expected as the form submission doesn't contain enough information to tell the default model binder to create any instances of PersonTypeOne and PersonTypeTwo classes. So, is there any way to get such functionality from the default model binder?

• Reasonable expectation to support new Operating Systems?

  - by Neil N

  My company has a desktop app originally developed for Windows XP. The original programmer has since been fired (fired with extreme prejudice I might add). I have fixed the app various times but overall try to avoid it, it is a mess and the only real way to fix it is to completely rewrite it, which could take a year. We have been trying to "forget" about this app, and instead steer clients towards our web version, which is more up to date, easier to maintain, easier to extend, and WAY easier to support. Most clients agree, the web version is just better all around. However we have one client that insists on using the desktop app. The app required a little duct tape to get working on Vista, but now completely breaks on Windows 7. I'm not even sure WHAT all the fixes are to get it working on Win7 (the current time estimate stands at "miracle") but after both installing the RELEASE build, and running the DEBUG build from Visual Studio, the app has errors on nearly every user action, and from what I can see from a high level test run, none of them are related. Since Windows 7 did not exist when this app was developed, is my company really expected to make all the required changes to make it function as "smoothly" as it did on XP?

• Why do System.IO.Log SequenceNumbers have variable length?

  - by Doug McClean

  I'm trying to use the System.IO.Log features to build a recoverable transaction system. I understand it to be implemented on top of the Common Log File System. The usual ARIES approach to write-ahead logging involves persisting log record sequence numbers in places other than the log (for example, in the header of the database page modified by the logged action). Interestingly, the documentation for CLFS says that such sequence numbers are always 64-bit integers. Confusingly, however, the .Net wrapper around those SequenceNumbers can be constructed from a byte[] but not from a UInt64. It's value can also be read as a byte[], but not as a UInt64. Inspecting the implementation of SequenceNumber.GetBytes() reveals that it can in fact return arrays of either 8 or 16 bytes. This raises a few questions: Why do the .Net sequence numbers differ in size from the CLFS sequence numbers? Why are the .Net sequence numbers variable in length? Why would you need 128 bits to represent such a sequence number? It seems like you would truncate the log well before using up a 64-bit address space (16 exbibytes, or around 10^19 bytes, more if you address longer words)? If log sequence numbers are going to be represented as 128 bit integers, why not provide a way to serialize/deserialize them as pairs of UInt64s instead of rather-pointlessly incurring heap allocations for short-lived new byte[]s every time you need to write/read one? Alternatively, why bother making SequenceNumber a value type at all? It seems an odd tradeoff to double the storage overhead of log sequence numbers just so you can have an untruncated log longer than a million terabytes, so I feel like I'm missing something here, or maybe several things. I'd much appreciate it if someone in the know could set me straight.

• When to Store Temporary Values in Hidden Field vs. Session vs. Database?

  - by viatropos

  I am trying to build a simple OpenID login panel similar to how Stack Overflow's works. The goal is: User clicks OpenID/Oauth provider OpenID/Oauth stuff happens, we end up with the result (already made that) Then we want to confirm that the user wants to actually create a new account (vs. associating account with another OpenID account). In StackOverflow, they keep a hidden field on a form that looks like this: <form action="/users/openidconfirm" method="post"> <p>This is an OpenID we haven't seen on Stack Overflow before:</p> <p class="openid-identifier">https://me.yahoo.com/a/some-hash</p> <p>Do you want to associate this OpenID with your Stack Overflow account?</p> <div> <input type="hidden" name="fkey" value="9792ab2zza1q2a4ac414casdfa137eafba7"> <input type="hidden" name="s" value="c1a3q133-11fa-49r0-a7bz-da19849383218"> <input type="submit" value="Associate OpenID"> <input type="button" value="Cancel" onclick="window.location.href = 'http://stackoverflow.com/users/169992/viatropos?s=c1a3q133-11fa-49r0-a7bz-da19849383218'"> </div> </form> Initial question is, what are those hashes fkey and s? Not that I really care what these specific hashes are, but what it seems like is happening is they have processed the openid response and saved it to the DB in a temporary object or something, and from there they generate these keys, because they don't look like Oauth keys to me. Main situation is: after I have processed OpenID/Oauth responses, I don't yet want to create a new user/account until the user submits the "confirm" form. Should I store the keys and tokens temporarily in a "Confirm" form like this? Or is there a better way? It seems that using a temp database object would be a lot of work to manage properly. Thanks for the help. Lance

• Bring a subview to the top on mouseDown: AND keep receiving events (for dragging)

  - by d11wtq

  Ok, basically I have a view with a series of slightly overlapping subviews. When a subview is clicked, it moves to the top (among other things), by a really simple two-liner: -(void)mouseDown:(NSEvent *)theEvent { if (_selected) { // Don't do anything this subview is already in the foreground return; } NSView *superview = [self superview]; [self removeFromSuperview]; [superview addSubview:self position:NSWindowAbove relativeTo:nil]; } This works fine and seems to be the "normal" way to do this. The problem is that I'm now introducing some drag logic to the view, so I need to respond to -mouseDragged:. Unfortunately, since the view is removed from the view hierarchy and re-added in the process, I can have the view come to the foreground and be dragged in the same mouse action. It only drags if I leave go of the mouse and click on the view again, since the second click doesn't do any view hierarchy juggling. Is there anything I can do that will allow the view to move to the foreground like this, AND continue to receive the subsequent -mouseDragged: and -mouseUp: events that follow? I started along the lines of thinking of overriding -hitTest: in the superview and intercepting the mouseDown event in order to bring the view to the foreground before it actually receives the event. The problem here is, from within -hitTest:, how do I distinguish what type of event I'm actually performing the hit test for? I wouldn't want to move the subview to the foreground for other mouse events, such as mouseMoved etc.

• Using JSF, PrimeFaces and JPA: Create Basic WebApp without using Generated CRUD Classes, Forms, etc

  - by user2774489

  I am trying to build a basic CRUD application with NetBeans 7.4, JSF, PrimeFaces and JPA using MySQL. I have successfully done this by using the NetBeans wizards. I want to do this from scratch, no wizards. There seems to be a lack of support for the combo of JSF, PrimeFaces and JPA. When I say "lack", I mean a full example (I might be asking too much), without using the CRUD auto-gen templates/classes AND shows actual queries coded and passed to the datatables(primefaces). YouTube is full of non-English speaking examples using Hibernate (not JPA) and other examples that show flashy GUI's with no code. So far I understand you need an @Entity class (provides the physical build of the tables), a Controller (serializable) and the .xhtml web page to show the datatable.. what else? Also, I'm not seeing any posts or examples where queries are using with JPA/JSF and how they are tied together (in one place). I need to connect the dots here so that I can leverage JSF/JPA to create simple queries to populate my PF DataTables. I've read the blogs and I've googled the intranets until I'm blue in the face. Sending me a list of URL's to read to learn about each product is something I've already done. I get what they do independently, but am looking for the "How do they all connect" answer with maybe some basic code examples!! :)

• Not showing error when calling another function in Spring

  - by Javi

  Hello, I have a controller with 2 methods. The first one just add some lists to the model (the lists of my comboboxes) and return a JSP with a form. The second one validates the data and if there aren't errors it saves the data. The code looks like this: public String showForm(Model model){ //load some data into some lists return "tiles:myJSPfile"; } public String save(@Valid @ModelAttribute("MyData") Data data, BindingResult result, Model model){ if(result.hasErrors()){ //there are errors: show form with error messages //(but I need to reload the combobox lists) return showForm(model); } //save data } The problem is that in this way I don't see the error messages in the form (though I see by the debugger that it has found errors). I've thought that the problem comes because the showForm method doesn't have the error messages because it can't see the BindingResult, so I've added BindingResult as a parameter of showForm method, but it still doesn't work. I've added My Model Attribute as well but I get the same problem. If I just return the JSP file in the save method I can see the errors, but in this way I would need to add again in this other method the lists I had already added in the showForm (duplicated code). I can't save the data in session scope so it's compulsory to get again the lists after getting the error. if(result.hasErrors()){ //there are errors: show form with error messages return "tiles:myJSPfile"; } Why are errors not shown when I call a function to display my JSP different from the one I used for the validation? What's the best way to do this? Thanks.

• Display subclass data in XCode Expression window

  - by Nick VanderPyle

  I'm debugging an iPhone application I've written using XCode 3.2 and I cannot view the relevant public properties of an object I pull from Core Data. When I watch the object in the Expressions window it only displays the data from the base NSManagedObject. I'd like to see the properties that are on the subclass, not the superclass. If it helps, here's some of the code I'm using. Settings is a subclass of NSManagedObject. I created it using XCode's built-in modeler. Declared like: @interface Settings : NSManagedObject { } @property (nonatomic, retain) NSNumber * hasNews; @property (nonatomic, retain) NSString * logoUrl; @property (nonatomic, retain) NSNumber * hasPaymentGateway; @property (nonatomic, retain) NSString * customerCode; ... In the interface of my controller I have: Settings *settings; I populate settings with: settings = (Settings *)[NSEntityDescription insertNewObjectForEntityForName:@"Settings" inManagedObjectContext:UIAppManagedObjectContext()]; I then set the properties like: settings.hasNews = [NSNumber numberWithBool:TRUE]; I've tried casting settings as (Settings *) in the Expression window but that doesn't help. All I see are the properties to NSManagedObject. I'm using NSLog but would rather not.
