就可以使用标记值ditermine丈量按钮假设你有一个实例树按钮: -
@property (nonatomic, strong) UIButton *btn1;
@property (nonatomic, strong) UIButton *btn2;
@property (nonatomic, strong) UIButton *btn3;
然后设置类似按钮的标签: -
btn1.tag=1;
btn2.tag=2;
btn3.tag=3;
并为每个设置相同IBAction
按钮和: -
[btn1 addTarget:self action:@selector(difficultyButtonPressed:) forControlEvents:UIControlEventTouchUpInside];
[btn2 addTarget:self action:@selector(difficultyButtonPressed:) forControlEvents:UIControlEventTouchUpInside];
[btn3 addTarget:self action:@selector(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
如果您使用的是IBAction
id
那么你得到的按钮对象,如: -
- (IBAction)difficultyButtonPressed:(id)sender {
UIButton *button = (UIButton *)sender;
NSLog(@"Button tag is %d",button.tag);
}
为每个添加不同的“标签”值。 – Wain
我有,但我如何在prepareForSegue中引用它们 – StuartM
创建它们时,请保留对按钮的强烈参考 – LuisCien
