MGTwitterEngine檢查是否關注用戶

Question

我在iOS應用中使用MGTwitterEngine SDK。 我正在嘗試檢查一個用戶是否正在使用此方法關注另一個用戶：

- (NSString *)isUser:(NSString *)username1 receivingUpdatesFor:(NSString *)username2
{
    if (!username1 || !username2) {
        return nil;
    }
    NSMutableDictionary *params = [NSMutableDictionary dictionaryWithCapacity:0];
    [params setObject:username1 forKey:@"user_a"];
    [params setObject:username2 forKey:@"user_b"];

    NSString *path = [NSString stringWithFormat:@"friendships/exists.%@", API_FORMAT];

    return [self _sendRequestWithMethod:nil path:path queryParameters:params body:nil 
                            requestType:MGTwitterUpdatesCheckRequest 
                           responseType:MGTwitterMiscellaneous];
}

此方法始終返回此格式但不相同的字符串：

CB4C097E-6740-4536-885E-BAF7D8A981FD

基本上，獲得布爾值會更好，我不知道如何使用該值。

有任何想法嗎？

**編輯初始化_engine的代碼

        _engine = [[SA_OAuthTwitterEngine alloc] initOAuthWithDelegate: self];
    _engine.consumerKey = kOAuthConsumerKey;
    _engine.consumerSecret = kOAuthConsumerSecret;

Answer 1

這是一個異步請求，您必須將您的類設置為MGTwitterEngine的委托，並在必須在您的類中實現的以下方法中獲取結果：

- (void)statusesReceived:(NSArray *)statuses forRequest:(NSString *)connectionIdentifier;
- (void)directMessagesReceived:(NSArray *)messages forRequest:(NSString *)connectionIdentifier;
- (void)userInfoReceived:(NSArray *)userInfo forRequest:(NSString *)connectionIdentifier;
- (void)miscInfoReceived:(NSArray *)miscInfo forRequest:(NSString *)connectionIdentifier;

您可以在MGTwitterEngineDelegate.h中閱讀：

 // These delegate methods are called after all results are parsed from the connection. If // the deliveryOption is configured for MGTwitterEngineDeliveryAllResults (the default), a // collection of all results is also returned. 

在那里您可以檢查結果值。
