applicationDidFinishLaunching not running

Question

So I'm starting out with cocoa and ObjC. I'm trying to follow the example in the up and running objective C/cocoa book from oreilly. My applicationDidFinishLaunching doesn't seem to be getting called. I think it's a problem with the way I hooked everything up in the IB.

Does anyone see anything obvious that my untrained eyes do not?

Answer 1

Does your Application object have it's delegate set to your Application App Delegate object? Right click on Application in your IB window and set the delegate outlet to be your Application App Delegate object.

Answer 2

猜测：您没有设置将applicationDidFinishLaunching定义为应用程序委托的对象。

Answer 3

for those who do not use IB, make sure you specify the app delegate in main.m in the following way:

        return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));

instead of:

        return UIApplicationMain(argc, argv, nil, nil);
