一个视图控制器中的多个 UIActionSheet

Question

如果只有一个 -actionSheet:clickedButtonAtIndex: 方法，如何将多个 UIActionSheet 添加到单个 UIViewController 中？

Answer 1

为您的操作表设置名称或标签并执行类似的操作

  -(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
 {
   if(actionSheet==yourActionsheet1)
     {
      //your logic
       }
     if(actionSheet==yourActionsheet2)
     {
      //your logic
       }
    }

希望这会有所帮助

您可以创建多个操作表，如下所示：

actionSheet1 = [[UIActionSheet alloc] initWithTitle:@"Where to go"
                                                   delegate:self
                                          cancelButtonTitle:@"cancel"
                                     destructiveButtonTitle:@"Store 2"
                                          otherButtonTitles:@"Store 3",@"Store 4",@"Store 5",@"View Store Profile",nil];
 actionSheet2 = [[UIActionSheet alloc] initWithTitle:@"Where to go"
                                                   delegate:self
                                          cancelButtonTitle:@"cancel"
                                     destructiveButtonTitle:@"Store 1"
                                          otherButtonTitles:@"Store 3",@"Store 4",@"Store 5",@"View Store Profile",nil];
actionSheet3 = [[UIActionSheet alloc] initWithTitle:@"Where to go"
                                                   delegate:self
                                          cancelButtonTitle:@"cancel"
                                     destructiveButtonTitle:@"Store 1"
                                          otherButtonTitles:@"Store 2",@"Store 4",@"Store 5",@"View Store Profile",nil];

&之后检查哪个操作表被调用
- (void) actionSheet: (UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex{

if(actionSheet==actionSheet1)
{
}
else if(actionSheet==actionSheet2)
{
}
else if(actionSheet==actionSheet3)
{
}

您可以将多个操作表添加到同一个视图控制器。您可以为每个操作表设置一个标签，并在委托方法中检查该标签以执行必要的功能。
