iOS UIactionsheet 监听按钮点击事件

 

1.在当前的视图头文件添加协议 UIActionSheetDelegate

如：

@interface DebbieViewController : UIViewController<UIActionSheetDelegate>

2.在当前的视图的DebbieViewController.m文件中实现协议<UIActionSheetDelegate>的方法；

-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex{
    NSLog(@"you click buttonIndex is :%d",buttonIndex);
}

3.通过按键当前的视图的button按钮  显示actionsheet ；

-(void)clickbutton{
    UIActionSheet *action=[[UIActionSheet alloc] initWithTitle:@"this is title" delegate:self cancelButtonTitle:@"cancelbutton" destructiveButtonTitle:@"surebutton" otherButtonTitles:@"otherbutton 3",@"otherbutton4", nil];
    //显示action sheet ；设置一个parent 这个parent必须是view，并且是当前的视图
    [action showInView:self.view];
}
