    // ViewController.m1: – (IBAction)doNE:(id)sender { 2: 3: [self.view removeFromSuperview]; 4: [self.view addSubView:MasterViewController]; 4: }Error on line 4: “Unexpected interface name MasterViewController :expected expression”. I have two view controllers: ViewController and MasterViewController. I’ve set it up so that the first view is a ViewController but I’m trying to get a button to change the view.

    Hi I am writing an app in xcode 3.2.3. All I want to do is switch to another view but I am unsure of the best way to do this. I can do it either of these 2 ways…PreferencesViewController *screen = [[PreferencesViewController alloc]initWithNibName:nil bundle:nil];screen.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;[self presentModalViewController:screen animated:YES];[screen release];or using…PreferencesViewController *screen = [[PreferencesViewController alloc]initWithNibName:

    EDIT: Solved the problem myself. Turned out it was a leftover in the dealloc method that caused a UIButton to be released twice…I’m trying to display a UIViewController on top of another UIViewController like a popup. Problem is that the view seems to be getting overreleased. With NSZombieEnabled, I get the following error:[CALayer release]: message sent to deallocated instance 0x784bf40I use this code to add the view://self.someViewController is declared as (nonatomic, retain) self.someViewCo

    ios for-loop subview addsubview
    I have a question about the FOR loop and Subviews. I want to show a different SubView every time the loop runs with a different subview name. The name must be “hoofdstukController” + the i count. How can i do this? I tried a couple of methods but all crashed the app. This is my loop:_viewControllers = [[NSMutableArray alloc] init]; for (int i = 0; i < 10; i++) {CGRect frame = _scrollView.frame;frame.origin.x = frame.size.width * i;frame.origin.y = 0; hoofdstukController.view.frame = frame;[_s

    I realize that there are many questions similar to this one, but having looked through quite a bit of them, I still lack the confidence to know if what I’m doing is right. I apologize if this question is redundant, however I’d really like to nail down whether what I’m doing isn’t bad practice…To briefly summarize, I’m making a tool-like application, just for my testing. There is a UIToolbar on the bottom with a button. In terms of behavior, when the user clicks the button, it will open up a

    I have a MonoTouch tab view application. On one of my tabs, when a user clicks a button, I want to show another view. I do this with the following code:UIView.BeginAnimations(“flip”); UIView.SetAnimationDuration(1); UIView.SetAnimationTransition(UIViewAnimationTransition.FlipFromRight, View, true);NewFilesViewController newFilesViewController = new NewFilesViewController(); newFilesViewController.View.Frame = new System.Drawing.RectangleF(View.Frame.Top, this.View.Frame.Left, this.View.Frame.W

    iphone uiview uiimageview uiimage addsubview
    I want to change an image on a view, from a popup dialog of 4-6 icons (imagine like changing your image on a messenger application). The way I implement this modal popup is by creating a new view at IB, with opacity on the background, and then I load this as a subview:IconsViewController *iconsViewController = [[IconsViewController alloc] initWithNibName:@”IconsView” bundle:nil]; [self.view addSubview:iconsViewController.view];So, when the user touches an icon, I have- (IBAction)iconIsSelected:(

    I currently don’t have any problems using:-(IBAction)products:(id)sender {products = [[Products alloc] initWithNibName:@”Products” bundle:nil];[self.view addSubview:products.view]; }I tied this action to buttons to change my views. I’m sure this isn’t correct though because the views are being stacked right? Will my application crash because of this? Know of any good sample code to switch views via IBAction?

    I was developing an app for iOS 4.3 back in the summer on my iPhone 4 and things were working well. I put that project on the back burner while I was relocating jobs. With the release of iOS 5 I updated both my Xcode and iOS SDK to 4.2 and 5.0 respectively and I also bought a new iPod Touch running 5.0 for developing.My app still works in the iPhone 4.3 Simulator (unfortunately I don’t have the iPhone 4 to test on anymore), but it crashes consistently on the iPhone 5.0 Simulator, as well as th

The controller’r viewDidLoad method inserts a 4×30 image seperator between the 7 pairs then moves the view into position at the bottom of the screen. I can trace it through the initWithNibName’s so it appears to be alloc ining fine. It c

    ios crash mkmapview addsubview
    I’ve got a UIViewController that has been pushed onto a UINavigationController stack, which contains a single button with an ‘addMapToView’ target. When I press the button, the app crashes, usually with no stack trace, but occasionally an [xxx barStyle] unrecognized selector stack trace, where xxx could be anything from an NSString to a UILabel or anything else.This behavior appeared with the recent update to iOS 7.0.3. I had apps in the queue waiting for review that I had to reject because of

    I want to add a tableViewController as a child view controller of a containerViewController (shown below). According to Apple’s View Controller Programming Guide I can achieve this by the following lines of code inside my containerViewController:[self addChildViewController:tableViewController];[self.view addSubview:tableViewController.view];[tableViewController didMoveToParentViewController:self];In fact, that works fine. Now the problem is that I do not want to add the tableViewController’s vi
