我正在应用程序的核心数据中实现 iCloud。但问题是，当我在添加持久存储时切换 iCloud 帐户应用程序崩溃。以下是我得到的错误日志

我还在拦截 iCloud 帐户更改并删除存储文件并创建新文件。但我没有成功。请建议您是否知道我在做什么

最初检查天气您是否已登录 icloud 帐户，以下代码 

 NSURL *ubiq = [[NSFileManager defaultManager]
                       URLForUbiquityContainerIdentifier:nil];

if(ubip== nil)  
     NSLOG(no icloud acount);  
else  
     NSLOG(icloud acount);
