我正在尝试使用NXOauth2 pod 在我的 iOS 应用程序上处理 OAuth2 来实施解决方案。
我能够通过已安装的应用程序流程来获取 OAuth2 属性，包括-accessToken并且refreshToken该帐户已正确保存到我的帐户中NXOAuth2AccountStore（通过检查验证[[NXOAuth2AccountStore sharedStore] accounts]）。
现在我已经保存了令牌，我想在随后的应用程序打开时使用它们，而不是再次向用户请求访问权限。我在这里这样做：
- (NSArray *)allAccounts
{
NXOAuth2AccountStore *store = [NXOAuth2AccountStore sharedStore];
NSArray *accounts = [store accountsWithAccountType:kIDMOAuth2AccountType];
return accounts;
}
以下调用（用于获取一些用户详细信息）在用户完成批准流程后立即起作用，但在应用程序关闭并重新打开时不起作用。
- (void)requestOAuth2ProtectedDetails
{
[NXOAuth2Request performMethod:@"GET"
onResource:[NSURL URLWithString:@"https://www.googleapis.com/oauth2/v1/userinfo"]
usingParameters:nil
withAccount:[self allAccounts][0]
sendProgressHandler:^(unsigned long long bytesSend, unsigned long long bytesTotal) {
// e.g., update a progress indicator
}
responseHandler:^(NSURLResponse *response, NSData *responseData, NSError *error){
// Process the response
if (responseData) {
NSError *error;
NSDictionary *userInfo = [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableContainers error:&error];
NSLog(@"%@", userInfo);
}
if (error) {
NSLog(@"%@", error.localizedDescription);
}
}];
}
我应该如何使用保存的 accessToken / refreshToken 来：
- 使用查询数据
requestOAuth2ProtectedDetails？ accessToken如果需要，使用refreshToken我已保存的获取更新？
这是我得到的错误：

第一次通过，这有效：
- (void)performRequestWithSendingProgressHandler:(NXOAuth2ConnectionSendingProgressHandler)progressHandler
responseHandler:(NXOAuth2ConnectionResponseHandler)responseHandler;
{
NSAssert(self.me == nil, @"This object an only perform one request at the same time.");
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:self.resource];
[request setHTTPMethod:self.requestMethod];
self.connection = [[NXOAuth2Connection alloc] initWithRequest:request
requestParameters:self.parameters
oauthClient:self.account.oauthClient
sendingProgressHandler:progressHandler
responseHandler:responseHandler];
self.connection.delegate = self;
// Keep request object alive during the request is performing.
self.me = self;
}
我注意到以下几点：
(lldb) po self.account.oauthClient
<NXOAuth2Client: 0x8f1e760>
但在失败的情况下，会发生这种情况：
(lldb) po self.account.oauthClient
