为多个.realm文件执行域迁移

Question

我有多个领域文件（每个用户登录一次我的应用程序），我需要为文件系统中的每个领域文件运行迁移

      RLMRealmConfiguration *config = [RLMRealmConfiguration defaultConfiguration];

  config.schemaVersion = 1;
  config.migrationBlock = ^(RLMMigration *migration, uint64_t oldSchemaVersion) {

    if (oldSchemaVersion < 1) {
    //do the same changes for all file.realm in the filesystem 
    }
  };


  [RLMRealmConfiguration setDefaultConfiguration:config];

  [RLMRealm defaultRealm];

如何为每个文件系统数据库执行域迁移，而不仅仅是默认域文件？

+[RLMRealm migrateRealm:]在配置指定的路径上执行Realm的迁移：

RLMRealmConfiguration *config = [RLMRealmConfiguration defaultConfiguration];
config.schemaVersion = 1;
config.migrationBlock = ...;
config.path = @"path 1";
[RLMRealm migrateRealm:config];
config.path = @"path 2";
[RLMRealm migrateRealm:config];
