ios – 如何确定从三个按钮中按下了哪个按钮

- (IBACtion)difficultyButtonPressed:(id)sender {
    // Any difficulty @R_197_10288@cted
    [self performSegueWithIdentifier:@"mainGameTurnGuess" sender:self];
}

你可以使用Tag Value来设置Taped Button,假设你有树按钮例如： –

@property (nonatomic,strong)  UIButton *btn1;
@property (nonatomic,strong) UIButton *btn2;
@property (nonatomic,strong) UIButton *btn3;

然后设置按钮标签,如： –

btn1.tag=1;
btn2.tag=2;
btn3.tag=3;

并为每个按钮设置相同的IBACtion,并： –

[btn1 addTarget:self action:@@R_197_10288@ctor(difficultyButtonPressed:) forControlEvents:UIControlEventTouchUpInside];

[btn2 addTarget:self action:@@R_197_10288@ctor(difficultyButtonPressed:) forControlEvents:UIControlEventTouchUpInside];

[btn3 addTarget:self action:@@R_197_10288@ctor(difficultyButtonPressed:) forControlEvents:UIControlEventTouchUpInside];

- (IBACtion)difficultyButtonPressed:(UIButton*)sender
{
 NSLog(@"Button tag is %d",sender.tag);

     // you can use if else condition using sender.tag  like

      if(sender.tag==1)//first button related identifire
      {
           [self performSegueWithIdentifier:@"mainGameTurnGuess_FirstButtonIdentirier" sender:sender]; 
      }
      else if(sender.tag==2)//second button related identifier
      {
            [self performSegueWithIdentifier:@"mainGameTurnGuess_secondButtonIdentirier" sender:sender]; 
      }
      else   //Third button related identifier
      {
            [self performSegueWithIdentifier:@"mainGameTurnGuess_ThirdButtonIdentirier" sender:sender]; 
      }

}

对于信息

如果你在IBACtion中使用id,那么你得到的Button对象如下： –

- (IBACtion)difficultyButtonPressed:(id)sender {
    UIButton *button = (UIButton *)sender;
    NSLog(@"Button tag is %d",button.tag);
}
