I spent all day searching for a tutorial on how to integrate Game Center into my iPhone app with no luck. I found few of them but they are either incomplete or obsolete.
1. I need a tutorial or documentation or any working source code.
2. Do I absolutly have to add my app in iTunes Connect during dev/test phases?
Here's some documentation about GameCenter that should get you started: GameCenter Programming Guide.
And yes, you absolutely have to add your game to iTC during development as well as prepare all your leaderboards and achievements (if any). If your game isn't completed yet, I have found it useful to just add any screenshots to iTunes Connect until you finish. If you don't have any previous apps, simply put in any image of the correct size, same goes for the app icon.
Hope this helps!

Is their a reason why this may happen? I have emailed Apple via the iTunes Connect support link but not had a response.
The Game Center leaderboard has been live since the original version but will not pull through to latest version.

https://developer.apple.com/library/prerelease/content/releasenotes/General/WhatsNewIniOS/Articles/iOS10.html Apple kill the Game Center App but still it works online GameKit. Also Game Center going on for developers https://developer.apple.com/game-center/
So the app is no longer avaliable in iphone.
I have an iOS app using Sprite Kit that I would like to add a simple leaderboard. I have tried several tutorials, but all are for an older version of Xcode and iTunes connect. As of now I have successfully authenticated the user (ie. when I open the app it says welcome back, or asks to log in if I am not logged in).
Could someone please point me in the direction of a tutorial that encompasses a simple leaderboard (such as in Flappy Bird) that will explain the iTunesConnect side and coding within my app that is up to date with iOS 7 and Xcode 5? Thank you!
The apple documentation for leaderboards is quite good. It explains how to do the iTunes connection portion and another page has the Xcode implementation with code examples.
You can find the iTunes connect info here: https://developer.apple.com/library/ios/documentation/LanguagesUtilities/Conceptual/iTunesConnectGameCenter_Guide/Leaderboards/Leaderboards.html#//apple_ref/doc/uid/TP40013726-CH2-SW1
The code examples are here: https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/GameKit_Guide/Achievements/Achievements.html#//apple_ref/doc/uid/TP40008304-CH7-SW3
Outside of that the app coda link that Iraklii mentioned is a great one.
I am currently trying to find the most efficient way to continue a method in the background of my app.
I am probably adding location/gps to my app soon, so I was considering using that flag to keep the app Active in the background. However, I do not want to add that flag yet because I want to post an App Update before I add the location functionality.
I know the exceptions;
Apps that play audible content to the user while in the background, such as a music player app
Apps that keep users informed of their location at all times, such as a navigation app
Apps that support Voice over Internet Protocol (VoIP)
Newsstand apps that need to download and process new content
Apps that receive regular updates from external accessories
Besides asking for a more generic idea then these ^, can someone explain the "external accessory" flag please? I am recording video from an outside device. However, I do not know what constitutes an "external accessory".
I also see that iOS7 has introduced new Multi-tasking functionality but I haven't seen any examples that I understand can someone also explain that? Maybe that is a viable solution?
Thanks in advance!
iOS 5 introduced Notification Center Widgets and I would like to experiment with those widgets and make custom ones (with a Jailbroken device). I couldn't quite figure out how to make such a widget. The Widgets (WeeApps) are bundles stored in /System/Library/WeeAppPlugins. It would be great if anyone has already writren a guide or could share how the principal class of a WeeApp has to look like. Ideal would be to have a WeeApp NIC template for theos :)
Note: This question is regarding so called WeeApps, system plugins for Notification Center introduced in iOS 5. Not to be confused with Today View Extensions introduced in iOS 8.
I don't want to shameless-plug in here, but I wrote a small tutorial to help you with this.
How to write Notification Center Widgets for iOS (iOS 6 and Below)
Hope it helps you!
UPDATE
Please note this is for iOS widgets running iOS 6 and below - In other words, this is for old jailbreak development. I may write an iOS 8 tutorial eventually, but this one is not it.
OK i think i have found a good way to understand it, a sample widget with full source code available on github: https://github.com/WillFour20/WeeAppTest But whats most helpful is this tutorial and the NIC template for theos mentioned in the tutorial, I already made several widgets using this method and my custom NIC templates. http://weeplugins.com/blog/?p=1
I am developing an iPhone game, and I will implement Game Center in it.
Apparently, I need to do some configuration with my application in iTunes Connect first. Therefore I have to "create" my application in the iTunes Connect page, right? But, how do I do that without getting Apple's staff review my app since I am still working on it?
I tried making a new app like normal, but it asks me for a bunch of stuff like screenshots etc, but I have none to offer in the first place...
Fixed. It seems they won't even review it if there is no binary uploaded yet.
