ios - 由于 Spotify 问题，应用程序在启动时崩溃

Question

我们正在开发一个项目，从 Spotify 获取源。我们在其中集成了 Spotify 库。由于应用程序启动崩溃问题，该应用程序被 MFI 审批流程拒绝。我们被困在这里了。这确实很紧急，我们感谢您的快速帮助。

应用程序启动时，我们收到应用程序崩溃错误。我们正在调用一个方法，这可能是崩溃的原因，但我们不确定。

- (void)clearKeychain {
  for( NSString *serviceName in @[@"rdio",@"spotify",@"spotifyUsername",@"muzik"]) {
    DDLogVerbose(@"removing keychain entry for service = %@", serviceName);
    [MZUserManager removeTokenForService:serviceName];
  }

MZSpotifyService *spotify = (MZSpotifyService*)[[MZDataManager sharedManager] serviceWithName:[MZSpotifyService shortName]];
  [spotify.sessionManager logout];

  [MZRdioService rdio].delegate = nil;
  [[MZRdioService rdio] logout];
}

---------------------------------

- (MZBaseService *)serviceWithName:(NSString *)serviceName
{
    NSLog(@"active services : \n %@",_activeServices);
  return _activeServices[serviceName];
}

---------------------------------------

- (void)logout {
  [[SPSession sharedSession] logout:^{
    DDLogVerbose(@"logged out from spotify");
  }];
}

下面是日志

Answer 1

重要错误在这里:

The operation couldn’t be completed. (OSStatus error -34018 - client has neither application-identifier nor keychain-access-groups entitlements)

现在，至于你为什么触发它，我不知道。尝试用 Google 搜索该特定错误 — 它不是 Spotify 特有的。

但是，您似乎正在将 Spotify 凭据存储在钥匙串(keychain)中，并且您可能会通过清除钥匙串(keychain)中的内容来触发问题。不幸的是，“我们正在调用一个方法”并不是有用的信息。

现在，您不应该将 Spotify 凭据存储在钥匙串(keychain)中。绝对不是用户密码——这违反了服务条款。 CocoaLibSpotify 为您提供可以安全存储在 NSUserDefaults 中的 token 。

您可以在库附带的“Empty CocoaLibSpotify”示例项目中找到如何正确存储 Spotify 凭据的示例。

此外，在将存档版本提交到 App Store 之前，请尝试测试它们。如果在审核期间发生这种情况，则没有理由不在本地触发此操作。
