推荐答案

您需要在您的视图控制器上实现一个UIControl事件处理方法，并将其设置为全部按钮的处理程序。即在 -tableView：cellForRowAtIndexPath：函数中，您将执行以下操作：

You'll need to implement a UIControl event-handling method on your view controller, and set that as the handler for all your buttons. i.e. inside your -tableView:cellForRowAtIndexPath: function you would do something like:

[theCell.button addTarget: self
                   action: @selector(buttonPressed:withEvent:)
         forControlEvents: UIControlEventTouchUpInside];

然后您的事件处理程序将如下所示：

Then your event handler would look like this:

- (void) buttonPressed: (id) sender withEvent: (UIEvent *) event
{
    UITouch * touch = [[event touches] anyObject];
    CGPoint location = [touch locationInView: self.tableView];
    NSIndexPath * indexPath = [self.tableView indexPathForRowAtPoint: location];

    /* indexPath contains the index of the row containing the button */
    /* do whatever it is you need to do with the row data now */
}
