  • How to add an extra plist property using CMake?

    - by Jesse Beder
    I'm trying to add the item <key>UIStatusBarHidden</key><true/> to my plist that's auto-generated by CMake. For certain keys, it appears there are pre-defined ways to add an item; for example: set(MACOSX_BUNDLE_ICON_FILE ${ICON}) But I can't find a way to add an arbitrary property. I tried using the MACOSX_BUNDLE_INFO_PLIST target property as follows: I'd like the resulting plist to be identical to the old one, except with the new property I want, so I just copied the auto-generated plist and set that as my template. But the plist uses some Xcode variables, which also look like ${foo}, and CMake grumbles about this: Syntax error in cmake code when parsing string <string>com.bedaire.${PRODUCT_NAME:identifier}</string> syntax error, unexpected cal_SYMBOL, expecting } (47) Policy CMP0010 is not set: Bad variable reference syntax is an error. Run "cmake --help-policy CMP0010" for policy details. Use the cmake_policy command to set the policy and suppress this warning. This warning is for project developers. Use -Wno-dev to suppress it. In any case, I'm not even sure that this is the right thing to do. I can't find a good example or any good documentation about this. Ideally, I'd just let CMake generate everything as before, and just add a single extra line. What can I do?

  • http authenitcation in xcode

    - by user313100
    I am trying to make twitter work in my app and everything works fine except the code does not seem to recognize an error from twitter. If the username/password are not valid, I get an error message through this function: - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { NSString* strData = [[[NSString alloc] initWithBytes:[data bytes] length:[data length] encoding:NSASCIIStringEncoding] autorelease]; NSLog(@"Received data: %@", strData ) ; return ; } It prints: Received data: Could not authenticate you. . However, the app continues to the post a tweet view I have and ignores the error. Obviously, I do not have something setup right to detect such an error from twitter so my question is how do I get xcode to recognize an error like this? This uses basic http auth btw and don't mention anything about OAuth...just trying to get this to work for now.

  • Tab bar application with UINavigation Controller MOC not being retained.

    - by iamsmug
    I created a tab bar application from the template and added a navigation controller to one of the tabs. I have already created this app from the navigation app template already and is working. The reason I am doing it this way is because I need to add a tab bar and thought it would be easier starting by using the tab bar project template and adding the nav controller to it rather than the other way round. I have copied the data model over from the other project and added the relevant code to where it should be. The problem I am having is passing the moc from the app delegate to the tab with the nav controller on. Here is a snippet from my applicationDidFinishLaunching method in my app delegate: - (void)applicationDidFinishLaunching:(UIApplication *)application { [self createEditableCopyOfDatabaseIfNeeded]; Top_BananaTableViewController *top_BananaTableViewController = (Top_BananaTableViewController *)[navigationController topViewController]; top_BananaTableViewController.managedObjectContext = self.managedObjectContext; // Add the tab bar controller's current view as a subview of the window [window addSubview:tabBarController.view]; [window makeKeyAndVisible]; } Everything seems fine here but when it comes to the fetchedResultsController on my nav controller view it bombs out with: '+entityForName: could not locate an NSManagedObjectModel for entity name 'cards'' When I checked what was set to my managedObjectContext on that view it was null. I don't know why or where it is loosing it's setting. Please help.

    - by iphoneDev
    Hi, I want to mix audio files of different size into a one single .wav file. There is a sample through which we can mix files of same size [(http://www.modejong.com/iOS/#ex4 )(Example 4)]. I modified the code to get the mixed file as a .wav file. But I am not able to understand that how to modify this code for unequal sized files. If someone can help me out with some code snippet,i'll be really thankful.

  • NSArray containObjects method

    - by Anthony Chan
    Hi, I have a simple question regarding xcode coding but don't know why things are not performing as I think. I have an array of objects (custom objects). I just want to check if this one is within the array. I used the following code: NSArray *collection = [[NSArray alloc] initWithObjects:A, B, C, nil]; //custom "Item" objects Item *tempItem = [[Fruit alloc] initWithLength:1 width:2 height:3]; //3 instance variables in "Item" objects if([collection containsObject:tempItem]) { NSLog(@"collection contains this item"); } I suppose the above checking will give me a positive result but it's not. Further, I checked whether the objects created are the same. NSLog(@"L:%i W:%i H:%i", itemToCheck.length, itemToCheck.width, itemToCheck.height); for (int i = 0, i < [collection count], i++) { Item *itemInArray = [collection objectAtIndex:i]; NSLog(@"collection contains L:%i W:%i H:%i", itemInArray.length, itemInArray.width, itemInArrayheight); } In the console, this is what I got: L:1 W:2 H:3 collection contains L:0 W:0 H:0 collection contains L:1 W:2 H:3 collection contains L:6 W:8 H:2 Obviously the tempItem is inside the collection array but nothing shows up when I use containsObject: to check it. Could anyone give me some direction which part I am wrong? Thanks a lot!

    Hello! I use the UIImagePickerController class to display the Camera Roll contents. I have a second thread that saves an image to the Camera Roll. When the images has finished saving, it does not appear in the Camera Roll that’s open. Is there a way to force the Camera Roll to refresh? (Other than dismissing and displaying it again.)

  • Removing a UIView from its superView and expanding its frame to full screen

    - by Magic Bullet Dave
    I have an object that is a subclass of UIView that can be added to a view hierarchy as a subView. I want to be able to remove the UIView from its superView and add it as a subView of the main window and then expand to full screen. Something along the lines of: // Remove from superView and add to mainWindow [self retain]; [self removeFromSuperView]; [self addSubView:mainWindow]; // Animate to full screen [UIView beginAnimations:@"expandToFullScreen" context:nil]; [UIView setAnimationDuration:1.0]; self.frame = [[UIScreen mainScreen] applicationFrame]; [UIView commitAnimations]; [self release]; Firstly am I on the right lines? Secondly, is there an easily way for the object to get a pointer to the mainWindow? Thanks Dave

  • 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.

  • How can I build an app with multiple types of controllers?

    - by Sheehan Alam
    How can I accomplish the following: When my app loads a UIView will show 4 buttons Clicking on a button will load a UITabBarController (not a UIView with a UITabBar) that can display multiple views. This seems challenging to me, because in order for me to use the UITabBarController I need to add this to the window's subview in my appDelegate. By doing so, my app automatically will load with the UITabbarController in the root view.

  • How to push text from one UITextfield to another UITextfield in the next View? And back!?

    - by Chrizzz
    an Hi, I have an UITextField in one view, UITextField A in View A. And I have another in view B, UITextField B in View B. I use a Navigation Controller Bar to switch between the views. The UITextFields are properties and connected Outlets of both views A and B. On my view A there is an "Options"-button which pushes view B. So when you are typing in Textfield A, I would like the same text to appear in Textfield B. When you edit TextField B and you go back to view A (via the "Title View A"-button in de navigation bar), I would like the same text to re-appear in Textfield A. I expected this to be easy. But I can't get it working. I tried: ViewBController *controller = [[ViewBController alloc] initWithNibName:@"ViewBController" bundle:nil]; controller.TextFieldA.text = TextFieldB.text But nothing appeared in view B. And how do I get back? I dont want to use NSUserdefaults because I would have to remove the values also.

    - by srikanth rongali
    How can I remove the present view when I touched the close button. I did [self.view removeFromSuperView] when I added only one subView. It worked. But, I have now added another subView to the previous subView. I need to to get the parent view . How can I do it. My code of adding the subView is here. When I did the following only one view is removed. //FirstViewController: UIViewController -(void)libraryFunction:(id)sender { LibraryController *libraryController = [[LibraryController alloc]init]; [self.view addSubview:libraryController.view]; } //LibraryController: UIViewController -(void)viewDidLoad{ RootViewController *rootViewController = [[RootViewController alloc] initWithStyle:UITableViewStylePlain]; UINavigationController *aNavigationController = [[UINavigationController alloc] initWithRootViewController:rootViewController]; self.navController = aNavigationController; [aNavigationController release]; [rootViewController release]; [self.view addSubview:navController.view]; } //RootViewController: UITableViewController - (void)viewDidLoad { [super viewDidLoad]; self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Close" style:UIBarButtonItemStyleBordered target:self action:@selector(close:)]; } -(void)close:(id)sender { [self.view removeFromSuperview]; } Thank You.
