Question

当我尝试在Swift中集成代码时，我遇到了Quickblox的问题。

下面的代码在Objective-C中运行没有任何错误

AppDellgate.m文件

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    [QBSettings setApplicationID:kApplicationID];
    [QBSettings setAuthKey:kAuthKey];
    [QBSettings setAuthSecret:kAuthSecret];
    [QBSettings setAccountKey:kAcconuntKey];

    [[GeoDataManager instance] fetchLatestCheckIns];    

    return YES;
}

GeoDataManager.m文件

@implementation GeoDataManager

+ (instancetype)instance
{
    static GeoDataManager *instance = nil;
    static dispatch_once_t onceToken;

    dispatch_once(&onceToken, ^{
        instance = [self new];
    });

    return instance;
}

- (void)fetchLatestCheckIns
{
    QBLGeoDataFilter* filter = [QBLGeoDataFilter new];
    filter.lastOnly = YES;
    filter.sortBy = GeoDataSortByKindCreatedAt;

    QBGeneralResponsePage *page = [QBGeneralResponsePage responsePageWithCurrentPage:1 perPage:70];

    [QBRequest geoDataWithFilter:filter                            page:page                    successBlock:^(QBResponse *response, NSArray *objects, QBGeneralResponsePage *page) {
                        [[DataManager sharedDataManager] saveCheckIns:objects];
                    } errorBlock:^(QBResponse *response) {

                        NSLog(@"Error = %@", response.error);

                    }];
}

但是当我尝试从代码

下面的Swift基础项目调用相同的方法时

Swift AppDelegate。

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

        // Set QuickBlox credentials (You must create application in admin.quickblox.com).
        QBSettings.setApplicationID(kQBApplicationID)
        QBSettings.setAuthKey(kQBAuthKey)
        QBSettings.setAuthSecret(kQBAuthSecret)
        QBSettings.setAccountKey(kQBAccountKey)

         GeoDataManager .instance().fetchLatestCheckIns()

         return true
    }

我收到未捕获的异常'NSInvalidArgumentException'，原因是： '+ [QBRequest geoDataWithFilter：page：successBlock：errorBlock：]：无法识别的选择器被发送到班级。

我已经添加了GeoDataManager＆amp;为此创建了一个桥接标题。

任何人都可以帮我解决我做错的事吗？任何想法或建议都会很棒。
