Hello all.
in my iPad app I have a superview screen size and there im placing smaller
subviews, when I touch one of those I need to place on top another custom view
which draw a circle around the taped subview, so the subview is exactly in the
middle of the circle which is drawn in that view on top of it so give a fell of
selections, + another functionality I need to do with that circle, like rotate
the subview i tapped. Anyway, now ,if I tap somewhere between the edge of the
circle and the beginning of the view bellow, I remove the circle's view but
then I need to have the view bellow with the touch I did before in order to
move it..
Now the symptoms are : I touch in the described area, the circles view
disappears, but I can't move the view bellow the touch I initiated on the
circle's view, I need to lift the finger and then I can move the view I touch.
I tried subclassing UIWindow and overwritting sendEvent method, checking if I
have a subview under the touch to call that views touches methods and then call
[super send:event ]. but for a touch began I get the touch, but again for
moving I get nothing.
this is what I did there:
NSSet *touches = [event allTouches];
NSLog(@"size of set %i",[touches count]);
UITouch * aTouch = [touches anyObject];
UIView * viewUnderPoint;
CGPoint p = [aTouch locationInView:itemsView];
if((viewUnderPoint = [itemsView hitTest:p withEvent:event])){
NSLog(@"Found a view under %@",[[viewUnderPoint class]
description]);
NSMutableSet *began = nil;
NSMutableSet *moved = nil;
NSMutableSet *ended = nil;
NSMutableSet *cancelled = nil;
for(UITouch *touch in touches) {
switch ([touch phase]) {
case UITouchPhaseBegan:
if (!began) began = [NSMutableSet set];
[began addObject:touch];
break;
case UITouchPhaseMoved:
if (!moved) moved = [NSMutableSet set];
[moved addObject:touch];
break;
case UITouchPhaseEnded:
if (!ended) ended = [NSMutableSet set];
[ended addObject:touch];
break;
case UITouchPhaseCancelled:
if (!cancelled) cancelled = [NSMutableSet set];
[cancelled addObject:touch];
break;
default:
break;
}
}
// call our methods to handle the touches
if (began) [viewUnderPoint touchesBegan:began withEvent:event];
if (moved) [viewUnderPoint touchesMoved:moved withEvent:event];
if (ended) [viewUnderPoint touchesEnded:ended withEvent:event];
if (cancelled) [viewUnderPoint touchesCancelled:cancelled
withEvent:event];
}
based on the docs,
so I dunno if there is a way to get a view which is under another one on top,
receive the touches I did on that top most view.
Any ideas?
Thx
Gustavo
