GameKit成绩问题

Question

我的游戏中心成绩出现在游戏中心，所以我知道我的实现在报告中是正确的。

这方面有几个问题。

首先，在游戏中心，它没有在图像上显示百分比视图.尽管我已经报告了.02，但ie 2%的成绩接近于预期成绩。我知道这个成就是被报道的，因为如果我把100投进去，它就会记录这个成就。

第二，我的成就在用户看来并不是有回报的。据我所知，这个功能应该由gamekit自动处理。我的印象是小模式会出现，让用户知道他们完成了一项成就。我现在认为有一些事情我必须做，因为没有一个小的模式出现。

我会附上我的代码，但大部分都是库存的。

我的最后一个问题是检索分数。我相信我将不得不存储我自己的分数，因为我目前的实现看起来不像它会很好的啮合。

提前谢谢..。

}

Answer 1

很多问题..。

我对增量gamesComplete

• You应该在本地存储它们的逻辑感到困惑，而不是问GameCenter每个time.

• -getAchievementPercentageForIdentifier:总是返回0，因为GameKit方法是asynchronous.

• GKAchievement.percentageComplete是一个百分比。你需要乘以100。

我认为你必须做你自己的成就通知。
