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          


        

Answer 1

Useful macros that will give you the correct size based on the device orientation:

#define SCREEN_WIDTH ((([UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationPortrait) || ([UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationPortraitUpsideDown)) ? [[UIScreen mainScreen] bounds].size.width : [[UIScreen mainScreen] bounds].size.height)
#define SCREEN_HEIGHT ((([UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationPortrait) || ([UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationPortraitUpsideDown)) ? [[UIScreen mainScreen] bounds].size.height : [[UIScreen mainScreen] bounds].size.width)

Answer 2

Try this :

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

Answer 3

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
