Question

我对5个按钮使用相同的操作，想要知道哪个按钮被称为

Answer 1

在这种情况下，请尝试为按钮分配唯一标签。

在目标方法中重新获得按钮标记，如下所示

例如

-(void)targetMethod:(id)sender{

UIButton *button = (UIButton *)sender;

int clickedButtonTag = button.tag ;


}

Answer 2

为nib中的按钮添加标记值，然后在按钮操作中添加：

allbtn = sender;
    btntag = allbtn.tag;
    NSLog(@"btntag:%d",btntag);
    if(btntag==1)
    {
    }

现在您很容易找到您点按的按钮。

Answer 3

使用：

UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button addTarget:self 
           action:@selector(aMethod:)
 forControlEvents:UIControlEventTouchDown];
[button setTitle:@"Show View" forState:UIControlStateNormal];
button.frame = CGRectMake(80.0, 210.0, 160.0, 40.0);
button.tag=1;
[view addSubview:button];

然后使用：

-(void)aMethod:(id)sender{

UIButton *button = (UIButton *)sender;

int clickedBtnTag = button.tag ;

Nslog("clicked button tag is %d",clickedBtnTag);

}

试试这个，然后请还原我..
