禁用UIPageViewController手勢識別器，同時處理longPressed手勢

Question

我有一個UIPageViewController，每個頁面包含頁面上的多個UIViews，每個UIView允許在長按手勢後的Pan手勢，我在contentVC中使用下面的委託，但它出現了pageVC不關心我的限制，它繼續翻頁！當我在平移時，是否必須做任何事情來禁用翻頁？ （不得已將設置在PageVC像canTurn的變量，並將其設置爲NO，而平移是在行動....

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

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

Answer 1

你應該在PageVC添加-gestureRecognizer:shouldReceiveTouch:方法本身，或如果你不想要的PageVC自身添加它，你可以讓一個委託處理它

像：

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

    return no; 
} 

或

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