applicationDidFinishLaunching未被调用 [英] applicationDidFinishLaunching not invoked

问题描述

在我的appdelegate.m中，不会调用applicationDidFinishLaunching。
我读过这是因为我的应用程序代表没有正确连接，但我不知道如何连接它。我所做的是右键单击XIB文件中的Application，然后将委托出口拖到某处...但不知道在哪里。
任何帮助表示赞赏。
谢谢！

In my appdelegate.m, the applicationDidFinishLaunching is not invoked. I have read that this is due to the fact my "Application"'s delegate is not properly connected, but I don't know how to connect it. What I do is right-clicking on Application from the XIB file, and drag the delegate outlet somewhere... but don't know where. Any help appreciated. Thanks !

推荐答案

在MainMenu.xib中，确保有一个AppDelegate类的实例。要创建一个，将一个普通对象（蓝色立方体）拖到列表中，并将其类名设置为AppDelegate（或者您的app delegate类名称）。

In your MainMenu.xib, make sure there's an instance of your AppDelegate class. To make one, drag a plain object (blue cube) into the list and set its class name to AppDelegate (or whatever your app delegate class name is).

同样在MainMenu.xib，要连接它，将Application对象的连接拖到AppDelegate实例（蓝色立方体）并将其连接到代理插座。

Also in the MainMenu.xib, to connect it, drag a connection from the Application object to your AppDelegate instance (the blue cube) and connect it to the delegate outlet.

完成。
