Question

将cocos2d-objc项目更新为Xcode7，iOS9后，我的CCScrollView实例被破坏了。点击和平移手势无法识别+ xcode抛出控制台警告

警告：手势识别器（; target =＆lt;（action = handleTap：， target =）＆gt;＆gt;）是在storyboard / xib中设置的被添加到多个视图（ - ＆gt ;; layer = ＆gt;）一次，这是永远不允许的，而且是现在强制执行。从iOS 9.0开始，它将放在第一个视图中它被装入。

在修补CCScrollView并使用UIView的api操作当前的gestureRecoznigers列表并使用相应的API方法后，问题已得到解决

-addGestureRecognizer： -removeGestureRecognizer：

- (void) onEnterTransitionDidFinish
{
    // Add recognizers to view
    UIView* view = [CCDirector sharedDirector].view;

    /*
    NSMutableArray* recognizers = [view.gestureRecognizers mutableCopy];
    if (!recognizers) recognizers = [NSMutableArray arrayWithCapacity:2];
    [recognizers insertObject:_panRecognizer atIndex:0];
    [recognizers insertObject:_tapRecognizer atIndex:0];

    view.gestureRecognizers = recognizers;
     */
    [view addGestureRecognizer:_panRecognizer];
    [view addGestureRecognizer:_tapRecognizer];

    [super onEnterTransitionDidFinish];
}

- (void) onExitTransitionDidStart
{
    // Remove recognizers from view
    UIView* view = [CCDirector sharedDirector].view;

    /*NSMutableArray* recognizers = [view.gestureRecognizers mutableCopy];
    [recognizers removeObject:_panRecognizer];
    [recognizers removeObject:_tapRecognizer];

    view.gestureRecognizers = recognizers;*/
    [view removeGestureRecognizer:_panRecognizer];
    [view removeGestureRecognizer:_tapRecognizer];

    [super onExitTransitionDidStart];
}
