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

Question

我有一个 UIPageViewController 并且每个页面在页面上包含多个 UIViews，每个 UIView 允许在 longPress 手势后平移手势，我在 contentVC 中使用以下委托，但看起来 pageVC 不关心我下面的限制，它继续翻转这页纸！我在平移时是否必须做任何事情来禁用翻页？（最后的手段是像 canTurn 一样在 PageVC 上设置一个变量，并在平移运行时将其设置为 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-gestureRecognizer:shouldReceiveTouch:在 PageVC 本身中添加该方法，或者如果您不想在 PageVC 本身中添加它，您可以让委托处理它

像：

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

   return no;
}

或者

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