Question

我正在使用设置包来存储我的应用的基本用户首选项。启动后，我将设置首选项的默认值（如另一篇文章中所述）。但是，如果我启动settings.app并进行更改，则会丢失一些首选项。

这是我的捆绑文件中的组：

在进行编辑之前（首次设置默认值之后），以下内容存储在设置中;

bucket = 1;
"bucket_name" = Bucket;
"bucket_size" = 10000;
"colour_scheme" = Black;
"version_preference" = "0.5";

在更改首选项后，他们会报告以下内容;

bucket = 1;
"last_bucket" = 201203;

除了委托中的initialize方法中的初始设置之外，我没有进一步更改首选项。

任何建议表示赞赏。

更改设置应用后设置会丢失值
