Question

can’t i give the cornerRadius to UIViewController Object.

Answer 1

cornerRadius is a property of a CALayer, which is associated with a UIView. A view controller can’t have one, but it’s view property can have:

#import <QuartzCore/QuartzCore.h>

At the top of your view controller’s .m file

In viewDidLoad:

self.view.layer.cornerRadius = 10;

You will probably also want to set the borderWidth and borderColor properties of the layer, if you are looking for a visible rounded rect border, or masksToBounds if you just want to round off the corners.
