Before ios18, when two fingers are switched to single fingers, the printing scale value will not change. When switching to two fingers again, the pinch and zoom printing scale will change. The same operation is performed after ios18, and two fingers are switched to single fingers. Switch back to two fingers, and the scale printing will not change.
code here:
- (void)pinchGesture:(UIPinchGestureRecognizer *)recognizer {
NSSet <UIEvent*> *events = [recognizer valueForKey:@"_activeEvents"];
UIEvent *event = [events anyObject];
if (recognizer.state == UIGestureRecognizerStateBegan) {
NSLog(@"---- begin finger count: %d scale: %f",event.allTouches.count,recognizer.scale);
recognizer.scale = 1.0;
} else if (recognizer.state == UIGestureRecognizerStateChanged) {
NSLog(@"---- change finger count: %d scale: %f",event.allTouches.count,recognizer.scale);
// recognizer.scale = 1.0;
}
