Hello,
I would like to use Gamecenter/Leaderboard on Xojo.
I am struggling with handling GameCenter using iOSkit.
Logging in is OK, (maybe) I can send my score, but I cannot show Leaderboard.
Anyone can open Leaderboard on Xojo?
BTW, if interested, see my Xojo iOS alarm app here: http://suzu.ltd/en/waatanalarm/

Hi Jason, nice to meet you! Your library is so great!
I am working on
AchievementAndScoreHelper.DisplayLeaderboard method.
It has 2 args and I have no idea what I should pass for the first one.
Dim v As iOSview
v = New iOSView( )
App.aas.DisplayLeaderboard( v, “game001LB” )
this code works, but v is shown and do not get Leaderboard.
passing Self instead v crashes.
I wonder what should I pass for the first argument…
Any sample code or ideas?
Hi Yoshitaka,
Glad you are enjoying the library!
You should be using self as the parameter. Would you be able show the crash log (available by pressing cmd-/ in the simulator, or through the devices menu in Xcode from your phone/ipad)? That would help me to direct you on what needs to be changed, it is possible there is an error in my implementation.
Jason

Are you using a tab bar?
You mean a Navigation bar?
In my test project, the View1 has a button only, no navigation bars.
This is the error. I can do some searching tomorrow but I would google this and see if there is anything useful on resolving it.
Thank you very much for your reply. I am waiting your your reply since I am no good at Objective-C thing.
BTW, here is the project for testing : http://suzu.ltd/g1.zip
And No, I do not use Tabbar (I understand what TabBar is now… sorry)
I will take a look later today and let you know what I find.
I’ve identified the issue and pushed a fix to github. If you would like me to send you the example project back I can do so in PM.
Hi Jason,
Thank you very very very much for your fix! It works great!
Now I can easily continue working on my iOS game.
Thank you very much again for your great library!!
Good luck with the rest of your game and happy holidays to you too!

I didn’t want to open a new thread for this. Just have a question regarding the iOS Kit. First of all, it’s absolutely awesome! I don’t understand much of the code but I can still interact with GameCenter. Terrific work, thank you!
In the link above it is mentioned that you can reset the leaderboard in GameCenter. Is there some code for it in the iOS Kit? I haven’t found anything on that. Thank you!
Glad you are finding the module useful! Resetting the leaderboard isn’t possible with the code in iOSKit. I believe it must be done through iTunes connect. I’ll be honest that I’ve never tried that before
Thanks for your reply, Jason. I was wrong, I misread the article. It says “Resetting the achievements” and that is in your code. I find your iOSKit and Jeremy’s iOSDesignExtensions extremely useful and I want to thank you again for that. Is there a way I can donate to show my appreciation? Didn’t find anything on GitHub.
