在IOS中,如何将另一个对象的功能作为选择器?

selector as parameter in IOS

在我的例子中,我正在创建一个Objective-C(非Swift)主/细节应用程序,并希望使用以下init函数创建UIViewController类型的DetailController对象

详细介绍ViewController。h

@interfact DetailViewController : UIViewController
- (id)initWithNibName:(NSString *)nibName withSaveSelector:(SEL)saveSelector
@end

... 详细介绍了ViewController。m

- (id)initWithNibName:(NSString *)nibName withSaveSelector:(SEL)saveSelector
{
  self = [super initWithNibName:nibName bundle:nil];
  if (self) {
        UIBarButtonItem *done = [[UIBarButtonItem alloc]
                                 initWithBarButtonSystemItem:UIBarButtonSystemItemDone
                                 target:self
                                 action:saveSelector];
        [[self navigationItem] setRightBarButtonItem:done animated:YES];
  }
  return self;
}

现在我有了另一个视图控制器

@interface AnotherViewController : UIViewController
- (void)saveSelector:(id)sender;
@end

),我使用上面的视图控制器,就像这样。。。

AnotherViewController *avc = [[AnotherViewController alloc] init];
DetailViewController *dvc = [[DetailViewController alloc] initWithNibName:@"AnotherViewController" withSaveSelector:@selector(???)];

我应该在里面放什么???所以我可以将另一个ViewController::saveSelector()函数传递给DetailViewController?

我希望这有意义。
