如果要编程生成一组按钮，然后将其与IBActions相关联，该怎么办？如果我在Interface Builder中添加按钮很容易，但是对于这种情况我不能做。

How do I do if I want to programatically generate a set of buttons and then associate those with IBActions? It's easy if I add the buttons in Interface Builder, but that I cannot do for this case.

推荐答案

按钮有方法 - （void）addTarget：（id）target action ）action forControlEvents：（UIControlEvents）controlEvents 。

使用它的代码如下所示：

The code to use this would look like this:

UIButton *myButton = [[UIButton alloc] init...]; [myButton addTarget:something action:@selector(myAction) forControlEvents:UIControlEventTouchUpInside];

这假设您的IBAction命名为 myAction 并且某些是定义该操作的控制器。

This assumes that your IBAction is named myAction and that something is the controller for which that action is defined.
