在处理longPressed手势时禁用UIPageViewController手势识别器

Question

我有一个UIPageViewController，每个页面在页面上包含多个UIView，每个UIView在longPress手势之后允许Pan手势，我在contentVC中使用以下委托，但似乎pageVC不在乎我在下面的限制，并且它继续翻转这一页！ 在平移时是否必须做任何事情来禁用翻页功能？ （最后一招是在PageVC上设置一个变量，例如canTurn，并在平移进行时将其设置为NO。

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer{

    if ([gestureRecognizer isKindOfClass:[UILongPressGestureRecognizer class]] &&
        [otherGestureRecognizer isKindOfClass:[UIPanGestureRecognizer class]]) {
        return YES;
    }
    return NO;
}

Answer 1

您应该在PageVC本身中添加-gestureRecognizer:shouldReceiveTouch:方法，或者如果您不想在PageVC本身中添加它，则可以让委托来处理它。

喜欢：

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{
   if(someCase)
   {
      return yes;
   }

   return no;
}

要么

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{
   return [delegate shouldHandle:.....];
}
