    - by zoul
    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.)

  • Objective C Object Functioning & Passing Arrays

    - by Patrick
    I apologise if this has been asked before but I can't find the info I need. Basically I want a UITableView to be populated using info from a server, similar to the SeismicXML example. I have the parser as a separate object, is it correct to alloc, init an instance of that parser & then tell RootViewController to make it's table data source a copy of the parser's array. I can't include code because I haven't written anything yet, I'm just trying to get the design right before I start. Perhaps something like: xmlParser = [[XMLParser alloc] init]; [xmlParser getXMLData]; // Assuming xmlParser stores results in an array called returnedArray self.tableDataSource = xmlParser.returnedArray Is this the best way of doing it?

  • Using NSUserDefaults to load data depending on which table view cell is pressed

    - by Bad_APPZ
    I want my app to work just like the 'contacts' app on iOS. When a user selects a certain TableViewCell, i want to load certain data. No Matter which cell is pressed, Either "Joseph, Richard, or Shannon", This view comes up: Both of the views look the exact same, but they just display different information. So i guess my question is: How can I programmatically set a key @"cell1" @"cell2", etc... for each cell using NSUserDefaults? But here is the catch, I dont know how many cells will be added, so i cant hard code this, How can I create a key for each table view cell for how ever many is added? Thanks for the help!

    Hi! Following Scenario: I have a = UIViewController A that contains a UIScrollView I have a second UIViewController "B" (amongst other things it contains a button) and add it to the ScrollView of A myView *mView = [[myView alloc] init]; [myScrollView addSubview:mView.view]; Is there a way that once the button is pressed that it(view) removes itself from the scrollview? I thought in the direction of setting the delegate of mView to "A" ?! But not sure how that should work in detail.... Any suggestions? Thanks!

  • 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 remove the present view when I have added more than one subView ?

    - 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.

  • UIActivityIndicator not working properly?

    - by medma
    Hello frends, I have a problem regarding UIActivityIndicator. I applied "[spinner startAnimating]" at the IBAction on a button and then doing some process. After the process activityindicator should be stopped and then navigate to another view. But the activity indicator does not appear. When I remove the line "[spinner stopAnimating]" then the indicator appears but not at the instant button is pressed. It appears just before the other view loads, and apparently does not appear, I mean it does not appear but if we see very carefully then only it appears for an instant. Thanx in advance for any answer.

  • Loop a UIScrollviw with ViewControllers

    - by Jim
    Hi I'm trying to create a UIScrollView with loop that contains a collection of ViewControllers. The answer to this question here shows the code that is the basis for what I'm trying to do. It uses images instead of viewControllers. I've managed to get the all the viewControllers loaded (4) and displaying but the first view which is a duplicate of the last viewController is blank. I've tried creating a copy of this viewController and adding it to the array but this messes up the transition / count. Any suggestions?

My code as follow, -(void)splashAnimation{ window = [[UIWindow alloc] initWithFrame:CGRectMake(0, 0, 320, 420)]; //scrollView = [[UIScrollView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; scrollView = [[UIScrollView alloc] initWithFrame:[window bounds]]; scrollView.pagingEnabled = NO; scrollView.bounces = NO; UIImage *image = [UIImage imageNamed:@"splash.png"]; UIImageView *imageView = [[UIImageView alloc] initWithImage:image]; imageView.userInteractionEnabled = NO; [scrollView addSubview:imageView]; [scrollView setDelegate:self]; //[scrollView release]; /* window = [[UIWindow alloc] initWithFrame:CGRectMake(0, 0, 320, 420)]; UIView *splashView = [[UIView alloc] initWithFrame:[window bounds]]; UIImage *image = [UIImage imageNamed:@"splash.png"]; [splashView addSubview: [[UIImageView alloc] initWithImage:image]]; [window addSubview:splashView]; [window makeKeyAndVisible]; [window removeFromSuperview]; } - (void)applicationDidFinishLaunching:(UIApplication *)application { [self splashAnimation]; [self initControllers]; [window addSubview:[mainTabBarController view]]; [window makeKeyAndVisible]; } On my given code the one blank window comes up and stay on.

  • MPMoviePlayerContentPreloadDidFinishNotification seems more reliable than MPMoviePlayerLoadStateDidChangeNotification

    - by user567889
    I am streaming small movies (1-3MB) off my website into my app. I have a slicehost webserver, I think it's a "500MB slice". Not sure off the top of my head how this translates to bandwidth, but I can figure that out later. My experience with MPMoviePlayerLoadStateDidChangeNotification is not very good. I get much more reliable results with the old MPMoviePlayerContentPreloadDidFinishNotification If I get a MPMoviePlayerContentPreloadDidFinishNotification, the movie will play without stuttering, but if I use MPMoviePlayerLoadStateDidChangeNotification, the movie frequently stalls. I'm not sure which load state to check for: enum { MPMovieLoadStateUnknown = 0, MPMovieLoadStatePlayable = 1 << 0, MPMovieLoadStatePlaythroughOK = 1 << 1, MPMovieLoadStateStalled = 1 << 2, }; MPMovieLoadStatePlaythroughOK seems to be what I want (based on the description in the documentation): MPMovieLoadStatePlaythroughOK Enough data has been buffered for playback to continue uninterrupted. Available in iOS 3.2 and later. but that load state NEVER gets set to this in my app. Am I missing something? Is there a better way to do this?

  • 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!

  • 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.

  • Switching between TabBarController Views when event fired

    - by aahrens
    I have a UITabBarController with two different views to switch between. What I would like to do is when a button is clicked in View1 to switch directly to View2. Then in View2 if they click a button it switches them to View1. It transfers between View1 and View2 when the click on the tabBarController fine but I'm trying to perform the switching for them when an event occurs Is there a way to do this by calling a method on my UITabBarController? @interface CalcAppDelegate : NSObject <UIApplicationDelegate> { UITabBarController *tabBarController; }

  • IUNavigationController loading more viewControllers

    - by Goods
    Not a Noob as yesterday, but still green. I have a UITabbarcontoller and a IUNavigationController they seem to work fine. I have a UITableviewController to which I loads my NSMutable array. The user clicks a cell and didSelectRowAtIndexPath xib is loaded onto the stack. I have a 'Learn More' button on the current xib. I've tried a few approaches to load a newer xib when the 'Learn More' button is pressed but have failed. Im thinking it has to do with the Navigation Controller? Do I need to import the navigationcontroller to every ViewControllerSubclass I make? Thanks.

  • Localizing other pages in Settings.bundle

    - by joneswah
    I have other pages within my app preferences which are stored as separate files within the settings.bundle. It has come time to localize my app and I can only seem to get the Root values to localize. I was wondering whether there was a trick? The following image shows that my second screen is stored within a file called "MyPrefs.plist" and I have created a corresponding named file "MyPrefs.strings" in the en.lproj directory. Mirroring the same naming and location as the Root.plist and Root.strings. The values with the Root.plist are converted as expected but not in the extra screen. Is there any trick to localizing secondary screens with the settings.bundle?
