I was wondering in all iOS applications we have to write makeKeyAndVisible for our UIWindow object. So is there a example where we dont want our application to makeKeyAndVisible.
If we always require it for any application, then why dint apple automatically write it for us, like they did for @synthesize as part of iOS 6?
An app can have more than one window. The call to
makeKeyAndVisibleis used to specify which one is current.Despite the fact that most apps only have one window, there is no way to assume that your primary window is to be the key window. Therefore you must explicitly call
makeKeyAndVisible.
