为什么UILongPressGestureRecognizer在iPhone 6之后发布的设备上表现不同？

Question

在我的代码中，我有一个区域，当用户点击并保持时，UILongPressGestureRecognizer会导致动画运行，并且在动画结束时会调用一个方法。 （它基本上是在一个包含一个CGPoint的小区域广场上的长按，以便它开始长按动画，当它完成时，该点将被移除。）

问题：在iPhone 5s，SE和6上，UILongPressGestureRecognizer工作正常，但在之后发布的任何设备上，它很快被解雇，我在至少11种不同的设备上尝试过。 这是为什么？！ 我感谢任何帮助。

-(void)prepareLongPressGesture{
_longGesture = [[UILongPressGestureRecognizer alloc]
      initWithTarget:self
              action:@selector(handleLongGesture:)];
  _longGesture.delegate = self;
  _longGesture.allowableMovement = self.frame.size.width*0.15;
  _longGesture.minimumPressDuration = 1.0;
  [self addGestureRecognizer:_longGesture];
}

- (void)handleLongGesture:(UILongPressGestureRecognizer*)gesture {
  switch (gesture.state) {
    case UIGestureRecognizerStateBegan:
      [self removeModifiablePoint];
      break;
    case UIGestureRecognizerStateChanged:
    case UIGestureRecognizerStateEnded:
    case UIGestureRecognizerStateCancelled: {
      if (self.animatedView.superview) {
        [self.animatedView removeFromSuperview];
      }
    } break;

    default:
      break;
  }
}

- (void)removeModifiablePoint {
    CGFloat sizeOFLongPressAnimation = 0.0;

    if (IS_IPAD) {
        sizeOFLongPressAnimation = 0.15*self.frame.size.width;
    }else{
        sizeOFLongPressAnimation = 0.27*self.frame.size.width;
    }

  if (!_animatedView) {
      self.animatedView =
      [[UIView alloc] initWithFrame:CGRectMake(0, 0, sizeOFLongPressAnimation, sizeOFLongPressAnimation)];


    self.animatedView.alpha = 0.7f;
    self.animatedView.layer.borderColor = [UIColor redColor].CGColor;
    self.animatedView.layer.borderWidth = 3.f;
    self.animatedView.layer.cornerRadius = sizeOFLongPressAnimation / 2.0f;

    self.progressView = [[UIView alloc] initWithFrame:self.animatedView.bounds];
    self.progressView.backgroundColor = [UIColor redColor];
    self.progressView.layer.cornerRadius = sizeOFLongPressAnimation / 2.0f;

    [self.animatedView addSubview:self.progressView];
  }

  CGPoint center = [self.modifiablePointsArray[_modifiablePointIndex] CGPointValue];
  self.animatedView.center = center;
  [self addSubview:self.animatedView];
  self.progressView.transform =
      CGAffineTransformScale(CGAffineTransformIdentity, 0.1, 0.1f);

  [UIView animateWithDuration:2.f animations:^{
        self.progressView.transform = CGAffineTransformIdentity;
      }completion:^(BOOL finished) {
        if (finished) {
          [self.animatedView removeFromSuperview];
          [self.modifiablePointsArray removeObjectAtIndex:_modifiablePointIndex];
          [self setNeedsDisplay];
        }
   }];
}
