(and also link to QuartzCore.framework in your project), then..

self.textView.layer.borderColor = [UIColor redColor].CGColor;
self.textView.layer.borderWidth = 4.0f;

UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:self.textView.bounds 
                                               byRoundingCorners:UIRectCornerTopLeft | UIRectCornerTopRight
