我對5個按鈕使用相同的動作，並想知道哪個按鈕被調用？

Question

我使用同一個動作的5個按鈕，想知道哪個按鈕被稱爲

Answer 1

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]; 

-(void)aMethod:(id)sender{ 

UIButton *button = (UIButton *)sender; 

int clickedBtnTag = button.tag ; 

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

} 

試試這個，那麼請回復我..

Answer 2

給標籤值的按鈕，在筆尖然後在您的按鈕操作補充一點：現在

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

簡單，你可以輕鬆地查找你點擊了哪個按鈕。

Answer 3

在這種情況下，請嘗試爲按鈕分配唯一標籤。

在目標方法恢復按鈕標籤如下

如

-(void)targetMethod:(id)sender{ 

UIButton *button = (UIButton *)sender; 

int clickedButtonTag = button.tag ; 


}

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]; 

然後使用：

-(void)aMethod:(id)sender{ 

UIButton *button = (UIButton *)sender; 

int clickedBtnTag = button.tag ; 

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

} 

試試這個，那麼請逆向工程＆牛逼我..
