作为UIBarButtonItem的信息按钮不响应点击

Question

我正在尝试以编程方式添加和信息按钮到我的应用程序的导航。但是，它永远不会触发我正在注册的动作。

UIBarButtonItem* infoButton =[[UIBarButtonItem alloc] initWithCustomView:[UIButton buttonWithType:UIButtonTypeInfoLight]];
    [infoButton setTarget:self];
    [infoButton setAction:@selector(infoButtonTapped)];

按钮显示在我的导航栏中，但点击它不会传递到infoButtonTapped

Answer 1

将目标/操作添加到UIButton。当从UIButton设置时，条形按钮项的行为会有所不同。

UIButton *button = [UIButton buttonWithType:UIButtonTypeInfoLight];
[button addTarget:self action:@selector(infoButtonTapped) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *infoButton = [[UIBarButtonItem alloc] initWithCustomView:button];
