There is no border property in UIView…. classes but we can access CALayer class to set border. Since layer property is defined in the UIView class, all of UIView inherited class can use this property to set border. It needs to have #import <QuartzCore/QuartzCore.h> to access CALayer.
view.layer.borderWidth = 1; view.layer.borderColor = [[UIColor grayColor] CGColor];
