touchesBegan and touchesEnded detected on another subview

[risma]

hi i really got stuck in a week about this case. i have a UIBarButtonItem inside UINavigationItem, the hierarchy is like this

UIViewController
|
myViewController
|
view-> UIToolbar -> UIBarbuttonItem

->UINavigationBar -> UINavigationItem->UISegmentedControl -> UIBarButtonItem

The UIBarbuttonitem and UIsegmentedControl below UINavigationItem are made programmatically, but the others are made in IB. The BarButtonItem is a wrapper of segmentedControl.

in this case, i want to show a view after pressing or touching the barbuttonitem. In several thread i read in this forum, i knew that UIBarbuttonItem didn't inherit UIResponder, so i choose the NavigationBar to get the touch, and i define a frame for it.

this is the code i made :

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
	int indexSegment = _docSegmentedControl.selectedSegmentIndex;
	NSLog(@"index di touches began : %d", index);
	CGFloat x;
	
	if (indexSegment == 0) {
		x = 0.0;
	}else if (indexSegment == 1) {
		x = widthSegment + 1;
	}else if (indexSegment == 2) {
		x = 2*widthSegment + 1;
	}else if (indexSegment == 3) {
		x = 3*widthSegment+ 1;
	}else if (indexSegment == 4) {
		x = 4*widthSegment + 1;
	}
	
	CGRect frame = CGRectMake(x, 0.00, widthSegment, 46.00);
	
	UITouch *touch = [[event allTouches] anyObject];
	
	CGPoint gestureStartPoint = [touch locationInView:[self navBar]];
	[navBar becomeFirstResponder];
	NSLog(@"gesturestart : %f, %f", gestureStartPoint.x, gestureStartPoint.y);	
	NSLog(@"frame : %f, %f, %f, %f", frame.origin.x, frame.origin.y, frame.size.width, frame.size.height);
	
	if (CGRectContainsPoint(frame, gestureStartPoint)) {
		NSLog(@"begin");
		[NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(segmentItemTapped:) object:[self navBar]];
	}
}

the navBar was declare in myViewController.h and i set it as an IBOutlet.

-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{
	int indexSegment = _docSegmentedControl.selectedSegmentIndex;
	NSLog(@"index di touches ended : %d", index);
	
	CGFloat x;
	
	if (indexSegment == 0) {
		x = 0.0;
	}else if (indexSegment == 1) {
		x = widthSegment + 1;
	}else if (indexSegment == 2) {
		x = 2*widthSegment + 1;
	}else if (indexSegment == 3) {
		x = 3*widthSegment+ 1;
	}else if (indexSegment == 4) {
		x = 4*widthSegment + 1;
	}
	
	CGRect frame = CGRectMake(x, 0.00, widthSegment, 46.00);
	NSLog(@"frame ended : %f, %f, %f, %f", frame.origin.x, frame.origin.y, frame.size.width, frame.size.height);
	
	UITouch *touch = [[event allTouches] anyObject];
	
	CGPoint gestureEndPoint = [touch locationInView:[self navBar]];
	[navBar becomeFirstResponder];
	
	NSLog(@"lastPOint : %f, %f", gestureEndPoint.x, gestureEndPoint.y);
	
	if (CGRectContainsPoint(frame, gestureEndPoint)) {
		NSLog(@"inside");
		if (touch.tapCount <= 2) {
			[self performSelector:@selector(segmentItemTapped:) withObject:[self navBar] afterDelay:0.35];
			//[navBar performSelector:@selector(segmentItemTapped:) withObject:segmentItem afterDelay:0.35];
			NSLog(@"masuk g??");
		}
	}
	
	
}

touchesBegan and touchesEnded was detected when i tap at the toolbar, NOT in the navbar.

i did implemented the hitTest method like this :

-(UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event{
	UIView *touchedView = [navBar hitTest:point withEvent:event];
	NSSet *touches = [touches anyObject];
	
	return touchedView;
}

but it still nothing get better.

Somebody can decribe why this is happen? Regards
