即使我強加布爾值也總是假的

Question

我有一個UIView，在使用UILongPressGestureRecognizer之前，然后使用UIPanGestureRecognizer。 向UIPanGestureRecognizer發出有關UILongPressGestureRecognizer壓力的消息，但我的應用程序不采用布爾值，即使我強加為真，也總是錯誤的。 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");
  }

提前致謝

當您觸摸視圖時，平移識別器會立即觸發並檢查此后的移動。 長按識別器總是比平移識別器晚得多（ 長時間結束后）觸發。 我懷疑panGesture總是在longGesture之前longGesture 。 也許平底鍋識別器正在完全取消長按識別器。

您應該通過添加更多NSLog語句來檢查會發生什么。

-(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");
}
