Hello all, When I developed a view based project in XCode, My view works fine. But when I use a window based project and create a view on my own and try adding it as a subview to window, it gives me a white band at the bottom.

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 ...
What's the proper way to set a default value for a UIView subclass's property? Although I'm not using them yet, if the XIB provides a value I'd like it to override the default. But if the XIB doesn't provide a value, I'd like my default value. In this case, I'm thinking of a CGFloat value specifically. While it could be set to 0.0 this...
Hi, why can't I get my programmatically created UIScrollView (or plain UIViews) to sit where I want them?

Create DrawMapViewController. Add the UIBarButtonItems (MAP, PT, LN, PG) on the bottom toolbar. When you click on map button, you are able to pan/...
I have a ViewController which controls many subviews. When I click one of the buttons I initialize another viewcontroller and show it's view as the subview of this view. However the subview exceeds the bounds of the frame for subview and infact fills the entire screen. What could be wrong? I presume the problem is that UIViewController'...
Hi Everyone: I am attempting to call presentModalViewController on a UIViewController in order to bring up a Address Book "view", however I am running into a bit of a problem. The UIViewController that "controls" the app simply draws a view to the screen and then lets the view do all of the handling of user interaction, etc. But now, ...
Does anyone happen to know the maximum value for someView.bounds.size ? I'm creating a view hierarchy with where the accumulated bounding-box of all child views is equal to the root parent view. Cheers, Doug ...
So, I'm capturing multiple touches and determining the number and where each of the touches occurred and I'm seeing different behavior between a UIView UIViewController. Basically, the event handler is coded below: (in this case the touchesEnded, but it really doesn't matter). What happens in the View, is that I get the entire collect...
I have been struggling with this problem for some time and there seems to be no clear answer. Please let me know if anyone has figured this out. I want to display a photo in a UIScrollView that is centered on the screen (the image may be in portrait or landscape orientation). I want to be able to zoom and pan the image only to the edg...
