推荐答案
在应用程序的info.plist中,确保将NSPrincipalClass键更改为子类的名称.这将使Cocoa在应用程序加载时实例化正确的类-您无需执行其他任何操作即可使子类正常工作.另外,请查看此链接,它可能还会为您的问题添加一些见解.使NSApplication神秘化
In your app's info.plist, make sure you change the NSPrincipalClass key to the name of your subclass. This'll make Cocoa instantiate the correct class when the applications loads - you shouldn't have to do anything other than that to get your subclass working. Also, take a look at this link it may also add some insights to your question. Demystifying NSApplication
