    You can import #import <QuartzCore/QuartzCore.h> and try this,

    self.testButton = [UIButton buttonWithType:UIButtonTypeCustom];
self.testButton.backgroundColor = [UIColor redColor];
self.testButton.layer.borderColor = [UIColor blackColor].CGColor;
self.testButton.layer.borderWidth = 0.5f;
self.testButton.layer.cornerRadius = 10.0f;

    Or else you can use some custom image as the background image for this button.
