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];
选择某个选项后,我会在日志中显示一条消息,以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,我的按钮和标签就是这样定义的
@interface ViewController : UIViewController <UIActionSheetDelegate> @property (weak,nonatomic) IBOutlet UILabel *lbViewController1;
解决方法
UIActionSheet已被弃用,因此您应该使用iOS 8.0类型操作表的UIAlertController,但是要使用当前代码回答您的问题,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];
}
