Hi,
I'm writing an app that should be calling viewDidLoad, but it doesn't call
it. This app has to have a shared variable in the appDelegate and the
variable is also used by the viewController. I have a working copy from before I tried to put the variable in the appDelegate (importPic2WedMay2.zip) (but that also winds up at a white screen for some reason after login...from what I've read, that is because I need my Facebook variable in the app delegate), and then I have a copy after I moved the variable to the appDelegate
(importPicWedMay2.zip) that doesn't get to viewDidLoad and the login.
Is there anyone out there that might understand this? I'm not sure what could cause this. I also have an ios4 version that works, but I need it to be in ios5, so I'm trying to convert it. I can send a copy of what I have if anyone is interested in seeing it.
Thanks,
M
