Hi everyone,
I'm trying to make my own custom UIScrollView for some reason. The question is, is it possible to exactly mimic the event handling behavior of UIScrollView including 'delayed content touches' and 'cancellable content touches'? That is, the custom scroll view should delay handling the event until it can determine if scrolling is the intent, and it should also be able to cancel its subviews' touches later. The problem is as follows:
1) hitTest: should return immediately so I can't delay the determination of the touch owner.
2) We can't cancel a touch event later programmatically. There's no such api.
3) I tried to override the sendEvent: method, but it didn't help. Having to call [super sendEvent:] will send events to unintended views. Moreover, hit test has been already done when sendEvent: was called and we can't alter the value of UITouch.view later.
So again the question is, is it possible to make a custom UIScrollView including it's touch handling behavior without using UIScrollView?
Thanks in advance!
