Iphone: Get current view dimensions or screen dimensions

Question

Hello i want to get the width and height of my main view. I want the correct value in landscape or portrait mode. I've tried the following:

   NSLog(@"aaa %f", [UIScreen mainScreen].applicationFrame.size.width);   NSLog(@"zzz %f", self.view.frame.size.width); 

These give 300 in landscape and 320 in portrait mode, yes it is larger in portrait mode. So.. my view takes up the whole screen (- status bar) so I expect 480 in landscape mode and 320 in portrait mode. What happened to the rest of the pixels. Do I have to hardcode these values? Thanks.

Answer 1

Do either of the following lines work for you?

[[UIScreen mainScreen] bounds].size.height [[UIScreen mainScreen] bounds].size.width 

I suppose you can subtract the height of the status bar? Maybe i'm not understanding your question

Try this :

UIWindow* window = [UIApplication sharedApplication].keyWindow; NSLog(@"%f",window.frame.size.width);
