UIImageView *imageview = [[UIImageView alloc] initWithFrame:CGRectMake(20, 100, 100, 100)];

UIImage *anotherImage = [UIImage imageNamed:@"landscape.jpg"];

UIGraphicsBeginImageContextWithOptions(imageview.bounds.size, NO, 1.0);

[[UIBezierPath bezierPathWithRoundedRect:imageview.bounds cornerRadius:50] addClip];

[anotherImage drawInRect:imageview.bounds];

imageview.image = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();

[self.view addSubview:imageview];
