Question

我对 5 个按钮使用相同的操作，想知道哪个按钮被调用

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签如下

例如

-(void)targetMethod:(id)sender{

UIButton *button = (UIButton *)sender;

int clickedButtonTag = button.tag ;


} 

Answer 2

为 nib 中的按钮赋予标签值，然后将其添加到按钮操作中：

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

现在很简单，您可以轻松找到您点击的按钮。

Answer 3

采用：

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);

}
