Getting a frame from bounds

When you apply a transformation to UIView, its frame property becomes undefined and you need to calculate its frame by yourself. If you apply a transformation more than just a scaling or a translation, it’s convenient to get its frame as a path.

This method returns UIBezierPath of its frame.

- (UIBezierPath *)framePath {
    UIBezierPath *path = [UIBezierPath bezierPathWithRect:CGRectOffset(self.bounds, -self.bounds.size.width/2, -self.bounds.size.height/2)];
    [path applyTransform:self.transform];
    [path applyTransform:CGAffineTransformMakeTranslation(self.center.x, self.center.y)];
    return path;
}
