The UIKit reference says UIView is a superclass of UIWindow, but despite of this parentage, a UIWindow actually manages UIViews. This sounds so unusual to me. Does anyone know what the significants of this are in terms of software design? Many thanks. EDIT: I read the related paragraph in the iPhone programming guide. Yet I couldn't s...
FYI I'm programming in objective-C but anyone might be able to help. I've been sitting here for the past two hours trying to figure out what the problem is and I've done everything I know to debug this simple little coding problem. Check out the code below and I will explain. In the application, it starts out with MainScreenViewControlle...
Does the addSubview method actually load the view into the application or not? The reason I am asking is because I have two two views in my application. The application delegate adds the two views as subviews and then brings one of the views up front. Now, I have a print statement in each of the viewDidLoad methods for each view. When I ...
Should I put the UIToolbar right in the window at the bottom, and then put the view above it (so the view doesn't continue underneath the toolbar), or should I just make the view cover the whole window and then add the toolbar as a subview to the view? So my question is, should the toolbar be a subview of the view or the window? - the w...
In my ViewController, I have a UITableView with some custom cells in it. When I touch a cell I want to get the touch coordinates right there into my UIViewController. The problem is, I can only get coordinates from parts of the screen not occupied by the UITableView..., Whenever my touch falls in the parts of the screen with the UITableV...
It sure looks innocuous enough. In my App Delegate, I check NSUserDefaults for a flag to show tips at startup. If it’s set then, at the end of applicationDidFinishLaunching:, I do this: TipsViewController *vc = [[TipsViewController alloc] initWithNibName:@“TipsView" bundle:nil]; [window addSubview:vc.view]; [vc release]; The idea is...
The position of a UIView can obviously be determined by view.center or view.frame etc. but this only returns the position of the UIView in relation to it's immediate superview. I need to determine the position of the UIView in the entire 320x480 co-ordinate system. For example, if the UIView is in a UITableViewCell it's position within ...

Hi there. I am creating a project in which i have to change the main.m file, so that UIApplication doesnt appear straight away, so i deleted the following line from main.m int retVal = UIApplicationMain(argc, argv, nil, nil); and deleted these lines from AppDelegate - (void)applicationDidFinishLaunching:(UIApplication *)application ...
I am trying to change the background color of a UIWindow when an action is sent to the class MyController. However the UIWindow resides in the AppDelegate class so I don't have access to the variable to modify it using window.backgroundColor = [UIColor theColor]; in MyController. Here is the code for MyController.m: @implementation M...
I am subclassing MainWindow with UIWindow and in that using hit test method: -(UIView *)hitTestCGPoint)point withEventUIEvent *)event { UIView *hitView = [super hitTestoint withEvent:event]; if (hitView == self) return [[self subviews] lastObject]; else if([hitView isDescendantOfView:myView]) { NSSet *to...
I need three different sections in my app: a login screen, a main screen, and one that takes place in landscape mode, all totally different. I saw Apple insists that an app should have one window, so I'm asking: what would be best to use for this? Three big windows, or views? And how should the hierarchy look like? I don't have experienc...
I am receiving this error. I have no clue as to why it would be called, and google didn't really help, any suggestions? -[UIWindow endDisablingInterfaceAutorotation] called on <UIWindow: 0x4e0ec50; frame = (0 0; 320 480); opaque = NO; autoresize = RM+BM; layer = <CALayer: 0x4e0f9e0>> without matching -beginDisablingInterfaceAutorotation...
I'm trying to detect any touch on the iPhone's UIStatusBar but its not working. I've tried subclassing UIApplication and UIWindow to access it but still nothing ...
I've been trying to figure out what happens in the view hierarchy when methods like pushViewController:animated, presentModalViewController:animated, and tab switches in UITabBarViewController are used, as well as UIAlertView and UIActionSheet. (Side note: I'm doing this because I need to know whether a specific UIView of my creation is...
Hi, I want to program an "Add"-Window to my application, much like the "Add Contact"-window in the Contacts app or the "Add City"-window in the Weather app. My question is: how do I code the effect of sliding up that Contacts & Weather feature? -- Ry ...
OK, bear with me. I have a UIView which is supposed to cover the whole device (UIWindow) to support an image zoom in/out effect I'm doing using core animation where a user taps a button on a UITableViewCell and I zoom the associated image. The zooming is performing flawlessly, what I haven't been able to figure out is why the subview i...
I setup a UIWindow subclass as detailed in an answer from this post: http://stackoverflow.com/questions/150446/how-do-i-detect-when-someone-shakes-an-iphone/1351486#1351486 I am running into an issue where only the methods motionBegan: and motionCancelled: will fire.

I am subclassing UIWindow and creating an implementation of sendEvent: as follows: - (void)sendEvent:(UIEvent *)event { [super sendEvent:event]; // Send event to UIScrollView here } How can I send the event to a UIScrollView. I tried calling the touchesBegan:, etc. messages, but that did not do anything. ...
