Question

我想知道这是否是GCD和realm.io所需的并发方法。我收到了一个从错误的线程错误＆＃34;访问的领域，两者都写入同一个领域，但根据文档，这是允许的吗？

RLMRealm *realm = [RLMRealm defaultRealm];
NSString *username = @"username3";
NSString *realmPath = realm.path;

dispatch_queue_t remote_registration_queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0);
dispatch_async(remote_registration_queue, ^(void) {
    [KUser remoteRegisterUsername:username realmPath:realmPath];
});

dispatch_queue_t local_registration_queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0);
dispatch_async(local_registration_queue, ^(void) {
    [KUser localRegistrationWithUsername:self.username password:password realmPath:realmPath];
});

在每种方法中，我都在呼叫：

RLMRealm *realm = [RLMRealm realmWithPath:realmPath];

你是否尝试过而没有通过Realm的路径？

我认为正确的方法是在每个方法中使用RLMRealm *realm = [RLMRealm defaultRealm];来获取对正确Realm的引用。无需担心这条路。

因此，您应该能够减少首次引用的代码：

NSString *username = @"username3";

dispatch_queue_t remote_registration_queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0);
dispatch_async(remote_registration_queue, ^(void) {
    [KUser remoteRegisterUsername:username];
});

dispatch_queue_t local_registration_queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0);
dispatch_async(local_registration_queue, ^(void) {
    [KUser localRegistrationWithUsername:self.username password:password];
});

使用GCD实现Realm.io的正确方法？
