For this you need to import Quartz framework. You can also set Bordercolor, shadow color, corner width, etc to that view.
#import <QuartzCore/QuartzCore.h>
And try this code.
[self.YourView.layer setCornerRadius:1.0];
[self.YourView.layer setBorderColor:[[[UIColor grayColor] colorWithAlphaComponent:0.5] CGColor]];
[self.YourView.layer setBorderWidth:1.0];
[self.YourView.layer setShadowColor:[UIColor lightGrayColor].CGColor];
