即使我强加布尔值也总是假的

Question

我有一个UIView，在使用UILongPressGestureRecognizer之前，然后使用UIPanGestureRecognizer。 向UIPanGestureRecognizer发出有关UILongPressGestureRecognizer压力的消息，但我的应用程序不采用布尔值，即使我强加为真，也总是错误的。 我能怎么做？

 -(IBAction)longGesture:(UILongPressGestureRecognizer *)gestureRecognizer{


   if(fromRiga ==0){
    if ([gestureRecognizer state]==UIGestureRecognizerStateBegan){
        self.inLongPress = YES;
        self.view.backgroundColor =[UIColor darkGrayColor];
        gestureRecognizer.allowableMovement=200;

      }else if([gestureRecognizer state]==UIGestureRecognizerStateEnded){
        self.inLongPress = NO;
      }
}

 - (IBAction)panGesture:(UIPanGestureRecognizer *)gestureRecognizer
  {
    NSLog(@"inLongPress is %@", self.inLongPress ? @"YES": @"NO");
  }

提前致谢

当您触摸视图时，平移识别器会立即触发并检查此后的移动。 长按识别器总是比平移识别器晚得多（ 长时间结束后）触发。 我怀疑panGesture总是在longGesture之前longGesture 。 也许平底锅识别器正在完全取消长按识别器。

您应该通过添加更多NSLog语句来检查会发生什么。

-(IBAction)longGesture:(UILongPressGestureRecognizer *)gestureRecognizer {
    NSLog(@"Long gesture");

    if (fromRiga == 0){
        if ([gestureRecognizer state] == UIGestureRecognizerStateBegan){
            self.inLongPress = YES;
            self.view.backgroundColor =[UIColor darkGrayColor];
            gestureRecognizer.allowableMovement=200;

            NSLog(@"Long gesture began, self.iLongPress = %@", self.iLongPress ? @"YES" : @"NO");
        } else if([gestureRecognizer state] == UIGestureRecognizerStateEnded) {
            self.inLongPress = NO;
            NSLog(@"Long gesture ended, self.iLongPress = %@", self.iLongPress ? @"YES" : @"NO");
        }
    }
}

- (IBAction)panGesture:(UIPanGestureRecognizer *)gestureRecognizer {
    NSLog(@"Pan gesture, self.iLongPress = %@", self.iLongPress ? @"YES" : @"NO");
}
