如何将选定的 UIActionSheet 按钮的标题放入标签中?

How to get the title of the selected UIActionSheet button into a label?

我有一个带有一些选项的按钮。

- (IBAction)monstrarActionSheet:(id)sender {
    UIActionSheet *action = [[UIActionSheet alloc] initWithTitle:@"Titulo"
                                                        delegate:self
                                               cancelButtonTitle:@"Mejor no" destructiveButtonTitle:@"Que miedo" otherButtonTitles:@"Otro boton 1", @"Otro boton 2", nil];
    [action showInView: self.view];

选择一个选项后,我会在日志中显示一条消息,显示选择了哪个按钮。

-(void) actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex{
    /*if(actionSheet.tag == 1){

    }*/

    NSLog(@"El usuario seleciono el boton %ld", (long)buttonIndex);
}

在我的 ViewController.h 中,我的按钮和标签是这样定义的

@interface ViewController : UIViewController <UIActionSheetDelegate>

@property (weak, nonatomic) IBOutlet UILabel *lbViewController1;

如何将所选 UIActionSheet 按钮的标题放入我的 lbViewController1 标签中?

UIActionSheet 已被弃用,因此您应该为 iOS 8.0+ 使用类型为 sheet 的 UIAlertController,但要使用您当前的代码回答您的问题,您可以将标签设置为包含按钮的标题,如下所示:

-(void) actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex{
    /*if(actionSheet.tag == 1){

    }*/
    NSLog(@"El usuario seleciono el boton %ld", (long)buttonIndex);
    self.lbViewController1.text =  [actionSheet buttonTitleAtIndex:buttonIndex];
}
