touchesmoved

I am using - (void) touchesMoved to do stuff when ever I enter a specific frame, in this case the area of a button. My problem is, I only want it to do stuff when I enter the frame - not when I am moving my finger inside the frame. Does anyone know how I can call my methods only once while I am inside the frame, and still allow me to call it once again if I re-enter it in the same touchMove. Thank you. -(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [[event touchesForView:self.view] anyObject]; CGPoint location = [touch locationInView:touch.view]; if

I have recently send out a version of my game to TestFlight for internal testing. My friend noticed that on his iPhone 6S Plus the controls to shoot do not work correctly. The controls are as follow 1) left half of screen = jump 2) right half of screen = shoot 3) Slide and hold on right half of screen = start slow motion Now in my touches began method I have a slight delay for the shooting, so if touches moved is called it cancels the shooting and starts slow mo. This seems to be causing the problem on 3D Touch enabled phones. Digging further into this I came across this post iOS 9 Spritekit

So I have a Subclass of UIView that is suppose to detect touches. The view detect touches only if the touches started inside the current view. When the touches start outside of the view and they move inside my custom view touchesMoved doesn't get called. Any solution to detect moving touches that have not started in the current view? @implementation MycustomView - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { // This only gets called if touches have started in the current View } @end aryaxt The following solution worked. I have multiple instances of MyCustomView; as the

I have a UIImage view that responds to touch events. I want to cancel the touch sequence, i.e., further calls to touchesMoved: , if the touch goes outside of certain bounds. How can I do that? I know that in touchesMoved: I can inspect the coordinates of the touch object and ignore it, but what I don't know is how to cancel the sequence altogether. I don't see any method documented in the Apple Developer UIResponder Reference that I can call to cancel a touch sequence. This solution may be a bit kludgy, but you could implement and manually call - (void) touchesCancelled:(NSSet *)touches
