Question

How to get and set iphone screen sizes and View sizes dynamically.. Suppose i'm setting imageview for an iphone, it should also fits to the ipad screen..

Answer 1

To get the screen size, you can use

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

to get the size of your view, for example

UIViewController* myViewController = [[UIViewController alloc] init];

what you can do is similar to the one above

CGSize viewSize = myViewController.view.frame.size;

To set

myViewController.view.frame = CGRectMake(x, y, width, height);

Answer 2

to set use

view.frame = CGRectMake(x, y, width, height);

and to get

CGRect rect = view.frame;
