Intercepting/Hijacking iPhone Touch Events for MKMapView
- by Shawn
Is there a bug in the 3.0 SDK that disables real-time zooming and intercepting the zoom-in gesture for the MKMapView? I have some real simple code so I can detect tap events, but there are two problems:
zoom-in gesture is always interpreted as a zoom-out
none of the zoom gestures update the Map's view in realtime.
In hitTest, if I return the "map" view, the MKMapView functionality works great, but I don't get the opportunity to intercept the events.
Any ideas?
MyMapView.h:
@interface MyMapView : MKMapView
{
UIView *map;
}
MyMapView.m:
- (id)initWithFrame:(CGRect)frame
{
if (![super initWithFrame:frame])
return nil;
self.multipleTouchEnabled = true;
return self;
}
- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event {
NSLog(@"Hit Test");
map = [super hitTest:point withEvent:event];
return self;
}
- (void)touchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event
{
NSLog(@"%s", __FUNCTION__);
[map touchesCancelled:touches withEvent:event];
}
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent*)event
{
NSLog(@"%s", __FUNCTION__);
[map touchesBegan:touches withEvent:event];
}
- (void)touchesMoved:(NSSet*)touches withEvent:(UIEvent*)event
{
NSLog(@"%s, %x", __FUNCTION__, mViewTouched);
[map touchesMoved:touches withEvent:event];
}
- (void)touchesEnded:(NSSet*)touches withEvent:(UIEvent*)event
{
NSLog(@"%s, %x", __FUNCTION__, mViewTouched);
[map touchesEnded:touches withEvent:event];
}
