Not Recognizing Being Logged into Game Center Sandbox

The problem is when testing a game via Ad Hoc or build from Xcode, the game does not recognize that you are logged into Game Center.  When you access Game Center features, the Game Center login screen pops up, you log in, and that's it.  When reopening the game the same thing happens even if you are already logged in.

Apparently on iOS 7 once you cancel Game Center 3 times you are locked out of Game Center in sandbox for good.  No matter what.  Now you have to reset all your settings.  What a crappy iOS bug.  Details below:

iOS 7 Lets you Choose User-Set System Fonts

By using something like:

self.body.font = [UIFont preferredFontForTextStyle:UIFontTextStyleBody];

You can have the fonts in your app exactly how the user prefers.

Unable to validate application for iOS App Store, armv6 architecture missing

Ran into a problem building with Xcode 4.5 when submitting to the App Store.  Xcode 4.5 cannot build for devices running iOS lower than 4.3.  So to fix the error for this, simply change the deployment target to 4.3.  More explanation at stack overflow:

App Developer Stories

Experience is everything.  If you know how an app will do in the App Store before you make it, you would be rich and famous.  If you don't know how an app will do, you'd want to know how to make your app successful.  If you can't find out how to make your app successful, you'd at least want to know how other people have done it.  Below is a list of developer stories... good and... not so good.

Word Mate - Trial and Error.
Trainyard - A highly successful story that took time and planning.

Testing for network connectivity using Apple provided Reachability class

Apple provides their sample app, Reachability (link here), which demonstrates using the System Configuration framework to determine whether your device has network connectivity via WWAN or WIFI.


This link also was helpful in implementing our class to test apps to test their connectivity:
