GameKit成就問題

Question

我的遊戲中心成就出現在Game Center中，所以我知道我的實施在報告中是正確的。

幾個關於這個問題的問題。

首先，在Game Center中，它沒有顯示圖像上的百分比視圖...即在成就旁邊完成了2％，儘管我已經報告了0.02。我知道這個成就是有報道的，因爲如果我把它放在100上，它就會記錄下這個成就。

其次，我的成就並沒有在獎賞時顯現給用戶。據我瞭解，這個功能假設是由gamekit自動處理的。我的印象是小模態會讓用戶知道他們完成了一個成就。我現在認爲我必須做的事情，因爲沒有小模式出現。

我會附上我的代碼，但大部分都是現貨。

我最後的問題是檢索分數。我相信我將不得不存儲我自己的分數，因爲我目前的實現看起來並不會很好。

在此先感謝...

Answer 1

了許多問題。

• 我很困惑的背後的邏輯遞增gamesComplete
• 你應該在本地存儲它們而不是問的GameCenter每次。
• -getAchievementPercentageForIdentifier:將始終返回0，因爲GameKit方法是異步的。
• GKAchievement.percentageComplete是百分比。你需要乘以100.

我認爲你必須做你自己的成就通知。
