Launch a click in UIButton, but use touchsEnded in the main window

For example, I have a UIButton, which I posted in IB.

This function UIButtonhas two functions, depending on whether it has been touched inside or pulled out - it would be nice to at least maintain its operability for touching inward.

I want to click on my button and “drag out”, but use it -touchesEndedabove the rectangle when I finally release my click.

I know that one of the options is to cut UIButtonand use -touchesBeganthe mask, but it is a lot more effort and requires a good big rewrite (with 96 buttons in mind).

To paraphrase a little - I clicked on the button and clicked on the mouse, dragging the cursor (/ finger) to another point on my screen, and I want my view to recognize -touchesEndedwhen I finally release it. The problem is that the initial click is associated with the button, so it -touchesEndeddoesn’t happen in my main view ...

Am I trying to do it wrong? Also, am I clear?

EDIT: @Heckman formulated the question much lower

If I understand your question correctly, you touch one button contained inside some UIView and want to pull out your finger and recognize the point in the button add-in.

-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    [self.superview buttonPressed:self]

    _buttonPressed = button;
}

    if(self.buttonPressed) {
         //Process the release from your drag here. 
         for(UITouch * touch in touches) {

Now do something depending on the button you touched inside

Other things I did - I created a mask of the original UIButton as a UIImageView, which I made invisible on the touchdragoutside event (and reset on the above touchupinside), so that I have a button that I can drag
