在iOS上以编程方式向按钮添加操作

[btn    addTarget:self
            action:@SELEctor(indexAction)
     forControlEvents:UIControlEventTouchUpInside];

这很好用.但是,我现在想要将一个变量(int k)传递给indexAction方法.我无法让这个工作：

[btn    addTarget:self
            action:@SELEctor([self indexAction:k])
     forControlEvents:UIControlEventTouchUpInside];

我确信我做错了什么.这是上面代码的上下文：

-(void) iniTindexButtons {

    float buttonPadding = -8;
    float buttonWidth = 23;
    float buttonHeight = 80;
    CGRect frame = CGRectMake(0,0);
    for (int k=0;k<5;k++)
    {
        UIButton* btn = [[UIButton alloc] initWithFrame:frame];;        btn.tag = k;
        btn.frame = CGRectMake(0,k*(buttonPadding+buttonHeight),buttonWidth,buttonHeight);

        UIImage *newImage = [UIImage imagenamed:@"index.png"];
        [btn setBACkgroundImage:newImage forState:UIControlStateNormal];

        [btn    addTarget:self
                action:@SELEctor(self indexAction:k)
         forControlEvents:UIControlEventTouchUpInside];
    }
}

-(void)indexAction:(int *)buttonTag
{
    NSLog(@"buttonTag: %i",buttonTag);
}

编辑：

我将代码更改为：

// ...
[btn    addTarget:self
                action:@SELEctor(indexAction:)
         forControlEvents:UIControlEventTouchUpInside];

        //[self indexAction:k];

        [indexView addSubview:btn];
        [indexView sendSubviewToBACk:btn];
    }
}

-(void)indexAction:(id)sender
{
    NSInteger *tid = ((UIControl *) sender).tag;
    NSLog(@"buttonTag: %i",tid);
}

但现在我收到警告消息“初始化从整数中生成指针,而不是针对行NSInteger * tid =((UIControl *)sender).tag;

编辑：

这是正确的代码行：

NSInteger tid = ((UIControl*)sender).tag;
