 NSLog(@"Top Left View : Width %f height%f",self.topLeftView.frame.size.width,self.topLeftView.frame.size.height);

I have dragged the "View" from object library and put it on xib file.

But what if I want to get the screen size to check whether its iphone 4,iPhone 3 or iphone 5 or any iOS Device.

So that I can arrange other views accordingly.

Answer 1

You can use:

CGsize screenSize      = [[[UIScreen mainScreen] bounds] size];
CGFloat widthOfScreen  = screenSize.width;
CGFloat heightOfScreen = screenSize.height;

Answer 2

You can know it with the UIScreen properties

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

for iPhone 5 and iPod touch 5gen the height is 568

for other iPhones and iPods the height is 480

Edit: on iOS 8 the height and the width deppend on the orientation, so this sizes are for portrait, on landscape this sizes will be for the width instead. So, best choice is to read both and do the max
