How to get screen size using code?

 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.

use [[UIScreen mainScreen] bounds] or [[UIScreen mainScreen] applicationFrame] – Collateral

Using the following code [UIScreen mainScreen].bounds.size – Orvieto

Answer 1

You can use:

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

If your app is designed for only landscape or portrait mode you will need to compare the width to the height to determine the correct size. We cannot get the orientation reliably anymore. For example, I have an app designed only for portrait mode but if it is opened in landscape mode on an iPad the width and height are mixed up. – Compony

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

why the iphone 5 and ipod touch 5gen the height is 568 not 1136? – Kerin

Because it's the real size, not the pixel size, if you want the pixel size you have to multiply the [[UIScreen mainScreen] bounds].size.height * [UIScreen mainScreen].scale (you have to use something like this because scale isn't available in some cases CGFloat scale = ([mainScreen respondsToSelector:@selector(scale)] ? mainScreen.scale : 1.0f); ) – Footway

Answer 3

You can get the size of iPhone screen as

CGSize size = [UIScreen mainScreen].bounds.size;

Answer 4

UIScreen *screen = UIScreen.mainScreen;

It has all you need including bounds and scale (may be different for retina and non-retina).
