• How to Deploy my Open Source Projects using Maven's Central Repository?

  - by sfussenegger

  Is there anything I could do to get my own open source stuff into Maven's Central repository? I've wondered many times how I could get my own projects into Maven's Central repository. I was asking this myself, especially as I've seen some well known projects hosting their own repository, requiring users to add dependency and repository. At the same time, it's getting difficult for other projects to depend on those projects. As I neither want others to add an additional repository nor to host one myself, I'm looking for other ways. And why aren't some projects using the option to deploy to Maven Central in favor of their self-hosted repository? Any good reasons that aren't obvious?

• How to remove an observer for NSNotification in a UIView?

  - by sudo rm -rf

  Hello! I've added an observer in a custom UIView I've created under initWithFrame:. [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(updateZipFromLocation:) name:@"zipFoundFromLocation" object:nil]; The problem is, this view is a subview. When the view is loaded again, it calls the initWithFrame message again, thus adding two observers and so on. How can I remove the observer when the view is going to disappear? Since it is a UIView, it says that viewWillDisappear:(BOOL)animated is not a valid method. Any ideas?

• Is there an optimal way to render images in cocoa? Im using setNeedsDisplay

  - by Edward An

  Currently, any time I manually move a UIImage (via handling the touchesMoved event) the last thing I call in that event is [self setNeedsDisplay], which effectively redraws the entire view. My images are also being animated, so every time a frame of animation changes, i have to call setNeedsDisplay. I find this to be horrific since I don't expect iphone/cocoa to be able to perform such frequent screen redraws very quickly. Is there an optimal, more efficient way that I could be doing this? Perhaps somehow telling cocoa to update only a particular region of the screen (the rect region of the image)?

• How to programmatically generate WSDL from WCF service (Integration Testing)

  - by David Christiansen

  Hi All, I am looking to write some integration tests to compare the WSDL generated by WCF services against previous (and published) versions. This is to ensure the service contracts don't differ from time of release. I would like my tests to be self contained and not rely on any external resources such as hosting on IIS. I am thinking that I could recreate my IIS hosting environment within the test with something like... using (ServiceHost host = new ServiceHost(typeof(NSTest.HelloNS), new Uri("http://localhost:8000/Omega"))) { host.AddServiceEndpoint(typeof(NSTest.IMy_NS), new BasicHttpBinding(), "Primary"); ServiceMetadataBehavior behavior = new ServiceMetadataBehavior(); behavior.HttpGetEnabled = true; host.Description.Behaviors.Add(behavior); host.AddServiceEndpoint(typeof(IMetadataExchange), MetadataExchangeBindings.CreateMexHttpBinding(), "mex"); host.Open(); } Does anyone else have any better ideas?

• Software Protection: Shuffeling my application?

  - by Martijn Courteaux

  Hi, I want to continue on my previous question: http://stackoverflow.com/questions/3007168/torrents-can-i-protect-my-software-by-sending-wrong-bytes Developer Art suggested to add a unique key to the application, to identifier the cracker. But JAB said that crackers can search where my unique key is located by checking for binary differences, if the cracker has multiple copies of my software. Then crackers change that key to make them self anonymous. That is true. Now comes the question: If I want to add a unique key, are there tools to shuffle (a kind of obfuscation) the program modules? So, that a binary compare would say that the two files are completely different. So they can't locate the identifier key. I'm pretty sure it is possible (maybe by replacing assembler blocks and make some jumps). I think it would be enough to make 30 to 40 shuffles of my software. Thanks

• Passing Data thru NSTimer UserInfo

  - by zorro2b

  I a trying to pass data thru userInfo for an NSTimer call. What is the best way to do this? I am trying to use an NSDictionary, this is simple enough when I have objective c objects, but what about other data? I want to do something like this, which doesn't work as is: - (void) play:(SystemSoundID)sound target:(id)target callbackSelector:(SEL)selector { NSLog(@"pause ipod"); [iPodController pause]; theSound = sound; NSMutableDictionary *cb = [[NSMutableDictionary alloc] init]; [cb setObject:(id)&sound forKey:@"sound"]; [cb setObject:target forKey:@"target"]; [cb setObject:(id)&selector forKey:@"selector"]; [NSTimer scheduledTimerWithTimeInterval:0 target:self selector: @selector(notifyPause1:) userInfo:(id)cb repeats:NO]; }

• How to get cheap version control?

  - by gotch4

  Hello, I'm a programmer, contractor, self experimenter and so on. I'd need to have cheap version control. I've been working with Subversion and recently with Mercurial. I've seen around many cheap hosting but, even if they are great (like BitBucket), many of them don't allow many private projects (1 or 2). Much of the code I need to keep on VC is not open, maybe because it is stuff I'm working on for clients, or maybe because it's code I usually need for my development, but it is not intended and usable as a open source project. Now, I've a cheap web hosting, with unlimited space and free mysql. I CAN'T install Mercurial or SVN on those machinese, but I was asking myself if is it there a way to use a common CVS with it, with "common" I mean something that has its good IDE plugins (Eclipse or Netbeans) that may avoid me to write commands by hand. Thank you

• Overriding the admin Media class

  - by shacker

  Given an admin media class that sets up a rich text editor, like: class TutorialAdmin(admin.ModelAdmin): fields... class Media: js = ['/paths/to/tinymce.js',] I would like the ability to selectively override js depending on a field value in the model it references. I've added a "use_editor" boolean to the Tutorial model. The question is, how can I detect whether the current instance has that bool set? I'd like to end up with something like: class Media: if self.use_editor: js = ['/path/to/tinymce.js',] else: js = '' Ideas? Thanks.

• How to make an scrollable UITextField Inside UItableViewCell?

  - by user333624

  Hello everyone. I created a bunch of editable UITableViewCell by embedding an UITextField inside, but I have seen some apps that allows you to scroll the UItableview by scrolling inside an inactive editable cell. How can I do that? And how can I also dismiss the keyboard when tapping somewhere else? I know about the method: - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [[event allTouches] anyObject]; if (touch.tapCount == 1) { [self resignFirstResponder]; } else { }} I put it inside my custom table view controller but the method doesn't seem to be called upon a tap, and I don't know if even if it gets called will dismiss the keyboard. Any help will be appreciated.

• Using the system localizations on iPhone

  - by nevan

  I want to make a back button for a navigation controller with the title "Back" instead of the title of the previous controller. I'm using this code: UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:NSLocalizedString(@"Back", @"Back") style:UIBarButtonItemStyleBordered target:nil action:nil]; self.navigationItem.backBarButtonItem = backButton; I'd like to be able to skip localizing the "Back" string in my app (since I can only localize it in a limited number of languages). If I give my navigation controller no title, the back button will be automatically localized into whatever the language the user has chosen, so the system has translations of "Back" in many languages. Is there a way to access the localizations that are already present in the system and use them myself? These are things like "Back", "Cancel", "Done" and so on, which show up when creating one of the standard system buttons.

• iOS development license and itunes connect

  - by Andreas

  New to iOS development and everything with the license is driving me nuts. So i got a few questions. I have a developer account but not a license yet. If i buy a iOS developer license for $99, that license is then stuck to my account? Can one developer account have multiple iTunes Connect accounts or is it stuck to one? Before i started to read up on stuff my account got added to a company's iTunes Connect account. If i then buy a license would i be stuck to just develop to that company or is it possible to change? I want to develop for my self and also one specific company. Can i use the same licence or do i need two? Can you have multiple licenses/certifications or whatever its called in Xcode? Is the iOS Developer Program both for development and distribution?

• iPhone: One Object, One Thread

  - by GingerBreadMane

  On the iPhone, I would like to do some operations on an image in a separate thread. Rather than dealing with semiphores, locking, etc., I'd like to use the 'One Object, One Thread' method of safely writing this concurrent operation. I'm not sure what is the correct way to copy my object into a new thread so that the object is not accessed in the main thread. Do I use the 'copy' method? If so, do I do this before the thread or inside the thread? ... -(void)someMethod{ UIImage *myImage; [NSThread detachNewThreadSelector:@selector(getRotatedImage:) toTarget:self withObject:myImage]; } -(void)getRotatedImage:(UIImage *)image{ ... ... UIImage *copiedImage = [image copy]; ... ... }

• Javascript recursive data structure definition

  - by Matt Bierner

  I need to define a data structure recursively in Javascript. Here is a simple example of a circular linked list: // List a very simplified example of what the actual (non list) code does. function List(f, r) { return function(){ return [f, r]; }; } var head = List('a', List('b', List('c', head))); When this is executed, head in List 'c' is resolved to undefined, not List 'a' as I need. List is an example function that returns a function (It is not an Javascript list that I can append to). I tried to wrap the definition of head is a self executing named function, but that blew the stack when head was resolved. What is the Javascript style solution that I am overlooking?

• Android Admob is not Showing Up

  - by Brandon

  Admob is not showing up on my emulator or on the device it self. I tried with testing mode on and off. Relevant Manifest data: permissions: <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE" /> meta data: <meta-data android:value="true" android:name="AD_REQUEST" /> The x's are actually my ID. My whole main.xml: <com.admob.android.ads.AdView android:id="@+id/ad" android:layout_width="fill_parent" android:layout_height="wrap_content" android:visibility="visible" android:layout_alignParentTop="true"/> Hopefully I can get this solved soon...

• Django - Passing arguments to models through ForeignKey attributes

  - by marshall

  I've got a class like this: class Image (models.Model): ... sizes = ((90,90), (300,250)) def resize_image(self): for size in sizes: ... and another class like this: class SomeClassWithAnImage (models.Model): ... an_image = models.ForeignKey(Image) what i'd like to do with that class is this: class SomeClassWithAnImage (models.Model): ... an_image = models.ForeignKey(Image, sizes=((90,90), (150, 120))) where i'm can specify the sizes that i want the Image class to use to resize itself as a argument rather than being hard coded on the class. I realise I could pass these in when calling resize_image if that was called directly but the idea is that the resize_image method is called automatically when the object is persisted to the db. if I try to pass arguments through the foreign key declaration like this i get an error straight away. is there an easy / better way to do this before I begin hacking down into django?

• Setting Corner Radius on UIImageView not working

  - by MarkPowell

  I'm at a bit of a loss. I've used the layer property of UIView to round the corners of multiple elements in my app. However, this one UIImageView is simply not complying. Not sure what I am missing. The UIImageView (called previewImage) is contained in a Table View Cell. I've tried setting the cornerRadius property multiple location (in the cell itself and in the controller that creates the cell) to no avail. static NSString *CellIdentifier = @"MyTableViewCell"; MyTableViewCell *cell = (MyTableViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:CellIdentifier owner:self options:nil]; cell = [topLevelObjects objectAtIndex:0]; cell.previewImage.layer.cornerRadius = 20; //Made it 20 to make sure it's obvious. } Is there something about the way cells are loaded that I'm missing?

• When to release the UIImage ?

  - by ragnarius

  I use the following code to draw a subimage UIImage* subIm = getSubImage( large, rect ); [subIm drawInRect:self.bounds]; where getSubImage is defined as follows UIImage* getSubImage(UIImage* uim, CGRect rc){ CGImageRef imref = CGImageCreateWithImageInRect(uim.CGImage, rc); UIImage* sub = [UIImage imageWithCGImage:imref]; CGImageRelease(imref); NSLog(@"subimage retainCount=%d", [sub retainCount]); // is 1 return sub; }//getSubImage Is the code correct? Is it safe to "CGImageRelease" imref? Has sub "CGImageRetained" imref? Should I release subIm (I get an error if I do)? Is subIm contained in the autorelease-pool, and , if so, how do I know this? In general, can one check if an object is contained in the autorelease pool (for debugging purpose)?

• UITabViewController hide / make appear a view in code

  - by user3689827

  I am using Xcode 5.1.1. I have a UITabViewController and used Storyboard to add 10 views to it. It works great and I get the "more" and table view all for free. I only want to show some of the tabs at the beginning. Once the user logs in with their Google+ account (I actually got that working), then I want the rest of the tabs to appear, since they are content sensitive to the user logging in. I have found: [[[[self.tabBarController tabBar]items]objectAtIndex:3]setEnabled:FALSE]; But I do not want the items just greyed out, I want them removed completely until they log in. Thanks

• Creating a Group of Groups in Django

  - by Greg

  I'm creating my own Group model; I'm not referring to the builtin Group model. I want each hroup to be a member of another group (it's parent), but there is the one "top" group that doesn't have a parent group. The admin interface won't let me create a group without entering a parent. I get the error personnel_group.parent_id may not be NULL. My Group model looks like this: class Group(models.Model): name = models.CharField(max_length=50) parent = models.ForeignKey('self', blank=True, null=True) order = models.IntegerField() icon = models.ImageField(upload_to='groups', blank=True, null=True) description = models.TextField(blank=True, null=True) How can I accomplish this? Thanks.

• Query for model by key

  - by Jason Hall

  What I'm trying to do is query the datastore for a model where the key is not the key of an object I already have. Here's some code: class User(db.Model): partner = db.SelfReferenceProperty() def text_message(self, msg): user = User.get_or_insert(msg.sender) if not user.partner: # user doesn't have a partner, find them one # BUG: this line returns 'user' himself... :( other = db.Query(User).filter('partner =', None).get() if other: # connect users else: # no one to connect to! The idea is to find another User who doesn't have a partner, that isn't the User we already know. I've tried filter('key !=, user.key()), filter('__key__ !=, user.key()) and a couple others, and nothing returns another User who doesn't have a partner. filter('foo !=, user.key()) also returns nothing, for the record.

• Changing the size of the UISearchBar TextField ?

  - by Padraig

  I have a UITableView with an Index on the side; I want to add a UISearchBar to it, but the index overlaps with the "x" to clear the search. I've noticed in the Contacts application, the textfield within the UISearchBar is resized to accommodate this, but I can't work out how to do this in my own app. I have tried the following in my viewDidLoad, but it does not seem to work. UITextField * textField = (UITextField *)[[self.search subviews] objectAtIndex:0]; CGRect r = textField.frame; [textField setFrame:CGRectMake(r.origin.x, r.origin.y, r.size.height, r.size.width-30)]; Any ideas?
