Here is how you can do it:

CGRect maskRect = CGRectMake(0.0, 0.0, CGRectGetWidth(<#something here#>), CGRectGetHeight(<#something here#>));
CAShapeLayer *maskLayer = [CAShapeLayer layer];
UIBezierPath *path = [UIBezierPath bezierPathWithRoundedRect:maskRect
                                           byRoundingCorners:(UIRectCornerBottomLeft | UIRectCornerTopLeft)
                                                 cornerRadii:CGSizeMake(<#corner radius#>, <#corner radius#>)];
maskLayer.path = path.CGPath;
self.layer.mask = maskLayer;
