Question

我的代码在这里：

RLMRealmConfiguration *configuration = [RLMRealmConfiguration defaultConfiguration];
NSString *filePath = [NSString stringWithFormat:@"%@",configuration.fileURL];
NSString *dateBaseName = @"aaa";
configuration.fileURL = [NSURL URLWithString:[[[filePath stringByDeletingLastPathComponent]
                                               stringByAppendingPathComponent:dateBaseName]
                                              stringByAppendingPathExtension:@"realm"]];
 configuration.encryptionKey = [self getEncriptionKey];
[RLMRealmConfiguration setDefaultConfiguration:configuration];
NSError *err = nil;
RLMRealm *realm = [RLMRealm realmWithConfiguration:configuration
                                             error:&err];
if (!realm) {
    NSLog(@"Error opening realm: %@", err);
}

但是当我迁移数据库时，似乎＆＃34; Realm文件解密失败＆＃34;并且应用程序崩溃了。

我的迁移代码在这里：

RLMRealmConfiguration *configuration = [RLMRealmConfiguration defaultConfiguration];
configuration.schemaVersion  = 3;
configuration.encryptionKey = [self getEncriptionKey];
configuration.migrationBlock = migrationBlock;
[configuration setDeleteRealmIfMigrationNeeded:YES];
[RLMRealmConfiguration setDefaultConfiguration:configuration];

帮助我!!!

您何时执行迁移代码？

您的代码应如下所示：

RLMRealmConfiguration *configuration = [RLMRealmConfiguration defaultConfiguration];

NSString *filePath = [NSString stringWithFormat:@"%@",configuration.fileURL];
NSString *dateBaseName = @"aaa";

configuration.fileURL = [NSURL URLWithString:[[[filePath stringByDeletingLastPathComponent]
                                               stringByAppendingPathComponent:dateBaseName]
                                              stringByAppendingPathExtension:@"realm"]];
configuration.encryptionKey = [self getEncriptionKey];
configuration.schemaVersion  = 3;
configuration.migrationBlock = migrationBlock;

[RLMRealmConfiguration setDefaultConfiguration:configuration];

NSError *err = nil;
RLMRealm *realm = [RLMRealm realmWithConfiguration:configuration
                                             error:&err];
if (!realm) {
    NSLog(@"Error opening realm: %@", err);
}

另请注意，如果需要迁移，[configuration setDeleteRealmIfMigrationNeeded:YES];将删除Realm文件，并且不会执行迁移。

领域问题，Realm文件解密失败，有什么问题？
