  • SQLite3 or SQLite Manager make me crazy !!! Please help me !! I have a presentation next week

    - by ahmet732
    My friend added 90 rows into the database, I tied it up to my app. In my table view name of my variables are shown in proper fashion but when I tapped one of them, in detailsViewController their description is wrong. It shows very old description of variables not the new ones in database. Moreover, it displays the same description for different variables. What's the problem ? What am i missing? My database is correct. It displays same desscriptions for different values. It makes me worried about. Additionally, when I added a new row to my db, it accepts it but it does not perceive it when i run the app. It shows new row in my tableview if and only if I change the name of my db file. I do not want to use another SQL manager ..

  • Parsing NSXMLNode Attributes in Cocoa

    - by Jeffrey Kern
    Hello everyone, Given the following XML file: <?xml version="1.0" encoding="UTF-8"?> <application name="foo"> <movie name="tc" english="tce.swf" chinese="tcc.swf" a="1" b="10" c="20" /> <movie name="tl" english="tle.swf" chinese="tlc.swf" d="30" e="40" f="50" /> </application> How can I access the attributes ("english", "chinese", "name", "a", "b", etc.) and their associated values of the MOVIE nodes? I currently have in Cocoa the ability to traverse these nodes, but I'm at a loss at how I can access the data in the MOVIE NSXMLNodes. Is there a way I can dump all of the values from each NSXMLNode into a Hashtable and retrieve values that way? Am using NSXMLDocument and NSXMLNodes.

  • dismissViewControllerAnimated completion block presenter view and modal view flow

    - by Patricia LaRue
    I did find an answer to this title and I did do a little research but I'm still not getting the flow. Here is what I want to happen: 1) click a button on the presenter view to open a modal view. 2) retrieve some value and click a button to close the modal view....sending the value to the presentor view and execute a method. I get that this works like a callback but I still can't figure out where to put the callback stuff. So, how exactly do I do this? A) In the presentViewController completion block, should I include the presenter view method to execute when modal view is completed? Or: B) In the modal view's dismissViewControllerAnimated completion block, should I include the presenter view method to execute when modal view is completed? Can somebody help me with some sample code? Or at least help me get the flow of which block to put the code in? Thank you, P

  • iOS Cell Label link

    - by hart1994
    Hi I am new to iOS programming and I need a little help. I have a table view cell which is populated by data from a .plist file. I need to be able to make a link within one of the cells.

  • Read Call History from iPhone on iOS 5 and above

    - by Sandeep Dhama
    I am developing an application and need to read the users call history from iPhone.I have go though all the forums and google it and found that we can get the records from teh callHistory sqlite database by "private/var/root/Library/CallHistory/call_history.db". But this path is not working from iOS 5 and above. Seems like apple has changed all their database path and structure so that no one can accees it. I have also seen some of the application on iTunes who are capable of getting the users call history like:-https://itunes.apple.com/us/app/callog/id327883585?mt=8 I have also check a mac desktop utility called "WonderShare Dr.Fone" which will fetch all the data from your iPhone like call history messages, notes , etc.How this utility is fetching the call history records and other details? If their is any API or private APIs by which i can get the callHistory data path please let me know.

  • NSView -(void)keyDown in console program

    - by Jonas Byström
    I'm not getting the -(void)keyDown callback on my inherited NSOpenGLView (note that mouseMoved does not work either though I do setAcceptsMouseMovedEvents:YES, but that is not an issue yet). It implements - (BOOL)acceptsFirstResponder { return YES; } but still no luck. My knowledgeable friend implied that it might have something to do with that the application is still a console application and not a bundled .app (I'm currently porting it). If so: is there some way to circumvent? Could the cause be something else? When I terminate my console application, I frequently see all my keypresses go to stdout so it does seem reasonable...

  • Any good way to set the exit status of a Cocoa application?

    - by buglesareking
    I have a Cocoa app which interacts with a server and displays a GUI. If there is a fatal error, I display an alert and exit. I'd like to set the exit status to a non-zero value to reflect that an error occurred, for ease of interaction with some other UNIX based tools. Unfortunately I've been unable to find a good way to do so - NSApplication doesn't seem to have any way to set an exit status. At the moment, I've subclassed NSApplication and added an exitStatus ivar (which I set in my app delegate when necessary), then overridden -terminate: so that it calls exit(exitStatus). This works fine, but it seems a bit grungy to me, not to mention that I may be missing something important that the stadnard `terminate: is doing behind the scenes. I can't call [super terminate:sender] in my subclassed method, because that exit()s without giving me a chance to set the status. Am I missing something obvious?

  • Can I access views when drawn in the drawRect method?

    - by GianPac
    When creating the content view of a tableViewCell, I used the drawInRect:withFont, drawAtPoint... and others, inside drawRect: since all I needed was to lay some text. Turns out, part of the text drawn need to be clickable URLs. So I decided to create a UIWebView and insert it into my drawRect. Everything seems to be laid out fine, the problem is that interaction with the UIWebView is not happening. I tried enabling the interaction, did not work. I want to know, since with drawRect: I am drawing to the current graphics context, there is anything I can do to have my subviews interact with the user? here is some of my code I use inside the UITableViewCell class. -(void) drawRect:(CGRect)rect{ NSString *comment = @"something"; [comment drawAtPoint:point forWidth:195 withFont:someFont lineBreakMode:UILineBreakModeMiddleTruncation]; NSString *anotherCommentWithURL = @"this comment has a URL http://twtr.us"; UIWebView *webView = [[UIWebView alloc] initWithFrame:someFrame]; webView.delegate = self; webView.text = anotherCommentWithURL; [self addSubView:webView]; [webView release]; } As I said, the view draws fine, but there is no interaction with the webView from the outside. the URL gets embedded into HTML and should be clickable. It is not. I got it working on another view, but on that one I lay the views. Any ideas?

  • Loading UINavigationController subclass from a Nib

    - by Rits
    My situation is as follows: My class SettingsViewController is a subclass of UINavigationController. That class contains the logic of its rootViewController. For example, it acts as the delegate and data source for two table views in that root view controller. I have no problem setting this up programmatically. In the initializer of SettingsViewController, I can create an additional UIViewController to serve as the root view controller, position the table views in its view, and set their delegates and data sources to self. But I want to load that root view via a Nib. The problem is, I do not know how to connect that Nib with my SettingsViewController, how to set the delegates and data sources. The SettingsViewController is not accessible from within the Nib. 'File Owner' represents the root view controller, not the SettingsViewController. How do I access my UINavigationController subclass from within my root view controllers Nib? Thanks in advance.

  • Releasing Autoreleasepool crashes on iOS 4.0 (and only on 4.0)

    - by samsam
    Hi there. I'm wondering what could cause this. I have several methods in my code that i call using performSelectorInBackground. Within each of these methods i have an Autoreleasepool that is being alloced/initialized at the beginning and released at the end of the method. this perfectly works on iOS 3.1.3 / 3.2 / 4.2 / 4.2.1 but it fataly crashes on iOS 4.0 with a EXC_BAD_ACCESS Exception that happens after calling [myPool release]. After I noticed this strange behaviour I was thinking about rewriting portions of my code and to make my app "less parallel" in case that the client os is 4.0. After I did that, the next point where the app crashed was within the ReachabilityCallback-Method from Apples Reachability "Framework". well, now I'm not quite sure what to do. The things i do within my threaded methods is pretty simple xml parsing (no cocoa calls or stuff that would affect the UI). After each method finishes it posts a notification which the coordinating-thread listens to and once all the parallelized methods have finished, the coordinating thread calls viewcontrollers etc... I have absolutely no clue what could cause this weird behaviour. Especially because Apples Code fails as well. any help is greatly appreciated! thanks, sam

  • UIDatePicker inside UIScrollView with pages

    - by Jason Martens
    I have a UIScrollView with 2 pages, and I can scroll horizontally between them. However, on one of my pages, I have a UIDatePicker, and the scroll view is intercepting the vertical touch events so I can no longer manipulate the date picker (except by clicking or tapping). Is there some way to tell the ScrollView to send the vertical touch events to the date picker, but send the horizontal touch events to the scroll view to switch pages?

    - by Sabi Tinterov
    Hi, My question is: is there a way to use the installed identity certificates on the phone from within my app. For example similar case like with saffary: if certain site requires client certificate, the user has to install it on the phone and then when authenticating saffary uses the installed certificate to authenticate. I need to do the same: 1.User installs certificate on the phone. 2. The user starts the application and authenticates using the installed certificate. Thanks

  • Disable ARC with Xcode 5

    - by user2187565
    First, sorry for my bad english, I'm french and had 15years old but StackOverFlow is for me the best forum for developers. So, in the previous versions of Xcode, we can disable ARC (Automatic Reference Counting) in the project settings when we create the project. Not now with Xcode 5 and ARC to pose me a problem: with an property list file, for the reading step, Xcode send me an error: "implicit conversion of 'int' to 'id' is disallowed with ARC". I had not the problem with the same code with Xcode 4. In my property list file, The keys are numbers and also in my viewController.m . NIKOS M.: No problem, but I don't see how I can add compiler flag with the 5th version of Xcode. The code (with french string...): NSString *error; NSString *rootPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]; NSString *plistPath = [rootPath stringByAppendingPathComponent:@"Save.plist"]; NSArray *keys = [NSArray arrayWithObjects:@"valeurCompteur1", @"valeurCompteur2", @"valeurCompteur3", @"valeurCompteur4", @"valeurCompteur5", @"nomCompteur1", @"nomCompteur2", @"nomCompteur3", @"nomCompteur4", @"nomCompteur5", nil]; NSArray *objs = [NSArray arrayWithObjects: compteur1, compteur2, compteur3, compteur4, compteur5, nameC1, nameC2, nameC3, nameC4, nameC5, nil]; REVIEW: When I disallow ARC for the target, an warning persist. How I can resolve that please ? Thank you very much.
