如何添加动作？

Question

我可以为UIBarButtonItem添加2个动作吗？ 首先，我正在使用UIBarButtonItem。看起来像。

 button = [[UIBarButtonItem alloc] initWithTitle:@"hoge"
                                           style:UIBarButtonItemStylePlain
                                          target:self
                                          action:@selector(method)];

接下来，我想添加它的动作。 如何添加动作？

您无法向UIBarButton添加更多操作，但UIButton可以：

UIButton * button = [UIButton buttonWithType:UIButtonTypeCustom];
[button addTarget:target action:@selector(action1) forControlEvents:UIControlEventTouchDragInside];
[button addTarget:target action:@selector(action2) forControlEvents:UIControlEventTouchDragInside];
[button addTarget:target action:@selector(action3) forControlEvents:UIControlEventTouchDragInside];

UIBarButtonItem* barButton = [[UIBarButtonItem alloc] initWithCustomView:button];
