无法在iOS Unity Build上禁用沙盒密码提示吗？

Question

启动我的应用程序时，它会不断提示我输入沙盒密码。我附了一张照片。

我不再使用IAP，而是要完全禁用它。但是，当我在Unity中关闭IAP服务时，出现此构建错误：

ArgumentException: The Assembly UnityEngine.Purchasing is referenced by Stores ('Assets/Plugins/UnityPurchasing/Bin/Stores.dll.old.dll'). But the dll is not allowed to be included or could not be found. 
UnityEditor.AssemblyHelper.AddReferencedAssembliesRecurse (System.String assemblyPath, System.Collections.Generic.List`1 alreadyFoundAssemblies, System.String[] allAssemblyPaths, System.String[] foldersToSearch, System.Collections.Generic.Dictionary`2 cache, BuildTarget target) (at /Users/builduser/buildslave/unity/build/Editor/Mono/AssemblyHelper.cs:152) 
UnityEditor.AssemblyHelper.FindAssembliesReferencedBy (System.String[] paths, System.String[] foldersToSearch, BuildTarget target) (at /Users/builduser/buildslave/unity/build/Editor/Mono/AssemblyHelper.cs:192) 
UnityEngine.GUIUtility:processEvent(Int32, IntPtr)

该怎么办？
