Question
self.window.rootViewController = self.tabBarController;
Request for member 'rootview controller' in something not a structure or union
what does this error mean?????
Solution
You explicitly mention iOS SDK 3.0 in your tags. I'm not sure if that's a mistake since the current SDK is 5.0 and nobody should be developing using iOS SDK 3 any more, but assuming it's not a mistake, the rootViewController property of window wasn't added until iOS SDK 4, so maybe that's why it doesn't work?
OTHER TIPS
It's trying to set the property rootViewController
on the object self.window
, but it can't. Does self.window
exist? What type is it? My guess is that you've copied and pasted code that's meant to go in the application delegate somewhere else.
