Question

我知道我写的代码是错误的。但我想要这样的东西。怎么做？

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
int totalcout = 0;
int passValue ;
for(int j=0; j<5; j++{
    for(int i=0; i<5; i++)
    {
        totalcout++;
        if(totalcount >1){
          break;
        }else{
        passValue = i;
        }
    }
    button.tag = j;
    [button addTarget:self action:@selector(button:) forControlEvents:UIControlEventTouchUpInside];
}


- (IBAction) button:(UIButton *)sender {
    NSLog(@"tag numbers are  %d", sender.tag);

    detailViewController.mutableArray1 = [oneMutableArray objectAtIndex:sender.tag];
    detailViewController.mutableArray2 = [twoMutableArray objectAtIndex:passValue];
}

我希望问题很清楚。提前谢谢

我收到了你的问题..你不能直接为任何UIView或任何子类直接分配两个标签。但你可以间接实现也许这段代码有助于实现你最终获得两个标签的意图

    #define First_Tag  100
    #define Second_Tag 200
  -(void)createButton
     {
    UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
    button.tag = ((First_Tag*10000)+30000)+(Second_Tag*10);
   [button addTarget:self action:@selector(button:) forControlEvents:UIControlEventTouchUpInside];
      }

 - (void) button:(UIButton *)sender 
 {
   int intTag2 = ((sender.tag-30000)%10000)/10;
   int intTag1 = ((sender.tag-(intTag2*10))-30000)/10000;
   NSLog(@"tag numbers are  %d and %d", intTag1, intTag2);
  }

我使用了几个大数字来编码标签..希望它能解决你的问题，分配两个标签

如何将多个标签传递给addTarget：action：forControlEvents？
