GameKit 成就问题

Question

我的游戏中心成就出现在游戏中心中，因此我知道我的实施在报告中是正确的。

有几个问题。

首先，在游戏中心中，它没有在图像上显示百分比视图...即成就旁边的 2% 完成，即使我已报告 0.02。我知道正在报告该成就，因为如果我向其扔 100，它就会记录该成就。

其次，我的成就不会以奖励的形式呈现给用户。据我了解，此功能应该由游戏包自动处理。我的印象是，会出现小模式，让用户知道他们完成了一项成就。我现在认为我必须做一些事情，因为没有出现任何小模态。

我将附上我的代码，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，因为我当前的实现看起来并不能很好地配合。

提前致谢...

Answer 1

很多问题...

• 我对递增 gamesComplete 背后的逻辑感到困惑。
• 您应该将它们存储在本地，而不是每次都询问 GameCenter。
• -getAchievementPercentageForIdentifier: 将始终返回 0，因为 GameKit 方法是异步的。
• 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。
