UICustomActionSheet 不调用委托方法来处理事件

Question

我在我的代码中使用 this 示例。它现在工作得很好，但是当我点击一个按钮时，它没有响应或调用任何方法。这是我的代码：

UICustomActionSheet* customActionSheet = [[UICustomActionSheet alloc] initWithTitle:nil delegate:nil buttonTitles:@[@"Cancel",@"Delete picture", @"Take a new photo", @"Choose from existing"]];
    [customActionSheet setButtonColors:@[[UIColor redColor]]];
    [customActionSheet setBackgroundColor:[UIColor clearColor]];
    [customActionSheet setSubtitle:@"Select your Choice"];
    [customActionSheet setSubtitleColor:[UIColor whiteColor]];
    [customActionSheet showInView:self.view];

这里是需要调用的方法

-(void)customActionSheet:(UICustomActionSheet *)customActionSheet clickedButtonAtIndex:(NSInteger)buttonIndex{
    NSLog(@"%d",buttonIndex);
}

问题出在您的代表。您已设置 nil。设置为self，你的问题就迎刃而解了。
