iOS iCloud
由于未捕获的异常“NSInternalInconsistencyException”而终止应用程序，原因：“执行 SQL 字符串时出错”INSERT INTO Y_UBMETA(YPEERID, YTRANSACTIONNUMBER)
未解决的错误 Error Domain=NSCocoaErrorDomain Code=134312 “存储元数据恢复似乎失败，请尝试再次将存储添加到协调器。如果不成功，请将数据迁移到新的泛化持久存储。” UserInfo=0xdba5b80 {NSLocalizedDescription=存储元数据恢复似乎失败，请尝试再次将存储添加到协调器。如果不成功，将数据迁移到新的泛化持久化存储。}, { NSLocalizedDescription = "存储元数据恢复似乎失败，请尝试再次将存储添加到协调器。如果不成功，将数据迁移到新的无处不在的持久存储。”；
我该如何解决这个问题？因为它是 iCloud 的内部查询。我把我的代码块放在我写的方法下面..
