This functionality would be fully complete if user can resize the view in different directions without it being rotated. I have seen this as a trend in many apps: one corner does a resize-rotate (done) and another corner does rotate only (can be easily done by adjusting your code). But how to resize the third corner without rotation so bounds can be easily adjusted to the touch location. This means resizing occurs unproportionally while the opposite corner is locked in its position? I tried this code but it does not perfectly work.

• (void)handleResizeGesture:(UIPanGestureRecognizer *)recognizer {
  CGPoint touchLocation = [recognizer locationInView:self.superview];
  CGPoint center = self.center;
  switch (recognizer.state) {
  case UIGestureRecognizerStateBegan: {
  initialBounds = self.bounds;
  initialLocation = touchLocation;
  [self.delegate stickerViewDidBeginRotating:self];
  break;
  }
  case UIGestureRecognizerStateChanged: {
  CGRect resizedBounds = CGRectMake(0, 0,
  initialBounds.size.width + touchLocation.x - initialLocation.x,
  initialBounds.size.height + touchLocation.y - initialLocation.y);
  self.bounds = resizedBounds;
  [self setNeedsDisplay];
  [self.delegate stickerViewDidChangeRotating:self];
  break;
  }
  case UIGestureRecognizerStateEnded:
  [self.delegate stickerViewDidEndRotating:self];
  break;
  default: break;
  }
  }

As your demo code, if stickerViewA (content with UIImageView) the corner (remove or rotate side) under and not full cover via stickerViewB (content with UILabel),
than I can't remove or rotate stickerViewA.

I suggest you can select stickerViewA and bring it to front temporary,
and select other sticker or unselect stickerViewA push to really layer.

is it Possible To Add new Button in Middle of CHTSticker View ? I will try but Button is not Display in Center it is Display Out of View.

First: Thanks for the nice control!

There is a small problem in the handleCloseGesture routine: if you removeFromSuperview first, then the respondsToSelector returns false.

You should first call the delegate and then removeFromSuperview:

• (void)handleCloseGesture:(UITapGestureRecognizer *)recognizer {
  if ([self.delegate respondsToSelector:@selector(stickerViewDidClose:)]) {
  [self.delegate stickerViewDidClose:self];
  }
  [self removeFromSuperview];
  }

Kind Regards
