从同一个UIButton关闭sheetViewController之前如何执行IBAction？ [英] How to perform IBAction before dismiss sheetViewController from same UIButton?

问题描述

我正在用Objective-C编写一个Cocoa Mac应用，并将Storyboard用于我的UI。

I am writing a Cocoa Mac app in Objective-C and using Storyboard for my UI.

我的sheetViewController.m中有一个确认按钮，我想要执行一些操作（保存一些设置）以及同时关闭sheetViewController。

I have a "Confirm" button in my sheetViewController.m which I want to perform some action (save some settings) as well as dismiss the sheetViewController at the same time. They both use the sheetViewController.m as outlets.

不幸的是，使用Storyboard，我只能选择一个接收到的动作（IBAction）或dismissController。

Unfortunately, with Storyboard, I can only pick one received action (IBAction) or dismissController.

我想先执行IBAction，然后解散工作表。我该怎么办呢？

I want to perform the IBAction FIRST, before dismissing the sheet. How can I accomplish this?

很高兴在代码中代替故事板，如果需要的话！

Happy to do this in code as well instead of Storyboard if necessary!

谢谢！

推荐答案

我发现了如何在代码中引用Storyboard ID：

I found out how to reference Storyboard ID in code:

在MainViewController上：

On MainViewController:

- (IBAction)didClickButton:(NSButton *)sender {
    SheetViewController *sheetViewController = [self.storyboard instantiateControllerWithIdentifier:@"SheetViewController"];
    // Must match Storyboard ID
    [self presentViewControllerAsSheet:sheetViewController];
}

在SheetViewController上：

On SheetViewController:

- (IBAction)didClickButton:(NSButton *)button {
    // Do something
    [self dismissViewController:self];
}
