如何在一個循環中創建按鈕併爲每個按鈕分配一個特定標籤

Question

我想創建一個按鈕集羣。爲此，我使用這樣的循環。

for (int i =0; i< [plistArray count];i++) { 

    editButton = [[UIButton alloc]initWithFrame:CGRectMake(width-10, -3.6, 39, 35)]; 
    [editButton setImage:[UIImage imageNamed:@"DeleteButton.png"] forState:UIControlStateNormal]; 
    [editButton addTarget:self action:@selector(deleteObjectViewImage:) forControlEvents:UIControlEventTouchUpInside]; 
} 

但是當我上的任何隨機按鈕分配的功能點擊未called.It當我點擊第一按鈕（在序列1,2,3）調用。

這裏有一個：

#define ButtonHeight 40 

    #define OffsetBetweenButtons 20 

    #define ButtonHeightPlusOffsetBetweenButtons (ButtonHeight+OffsetBetweenButtons) 

//create 6 buttons from 0,1,2,3,4,5 so totally 6 buttons 
for(int buttonIndex=0;buttonIndex<=5;buttonIndex++){ 

    UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect]; 

    [button addTarget:self 
       action:@selector(aMethod:) 
    forControlEvents:UIControlEventTouchUpInside]; 

    [button setTitle:@"Button" forState:UIControlStateNormal]; 

    [button setImage:[UIImage imageNamed:@"DeleteButton.png"] forState:UIControlStateNormal]; 

    //Set offset in Y axis 
    button.frame = CGRectMake(20.0, ButtonHeightPlusOffsetBetweenButtons * buttonIndex , 280.0, 40.0); 

    //Set Tag for future identification 
    [button setTag:buttonIndex]; 

    [YourView addSubview:button]; 

}
