• API
• 類方法 封裝
• JSON 數(shù)據(jù)轉(zhuǎn)換
• 數(shù)據(jù)庫 緩存 (根據(jù)需要寫)

問題來了 怎么使用呢餐屎？見最下面 （實(shí)例化方法中 調(diào)用即可）

類方法

+ (void)requestWihtMethodUrl:(NSString *)url
                      params:(NSDictionary *)params
                     success:(void (^)(id response))success
                     failure:(void (^)(NSError *err))failure {
    
    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    manager.requestSerializer.timeoutInterval = kTimeOutInterval;
    manager.responseSerializer = [AFHTTPResponseSerializer serializer];
    //設(shè)置相應(yīng)內(nèi)容類
    manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json",
                                                         @"text/html",
                                                         @"image/jpeg",
                                                         @"image/png",
                                                         @"application/octet-stream",
                                                         @"text/json",
                                                         @"text/plain",
                                                         nil];
    
    [manager POST:url parameters:params progress:^(NSProgress * _Nonnull uploadProgress) {
        
    } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        if (success) {
            success(responseObject);
        }
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        if (failure) {
            failure(error);
        }
    }];
}

JSON

- (NSDictionary *)jsonToDictionary:(id)json {
    NSDictionary *resultDic = [NSJSONSerialization JSONObjectWithData:json
                                                              options:NSJSONReadingMutableContainers
                                                                error:nil];
    return [resultDic valueForKey:@"serverResponse"] ? : [resultDic valueForKey:@"alibaba_aliqin_fc_sms_num_send_response"];
}

FMDB

//緩存數(shù)據(jù)到sqlite數(shù)據(jù)庫
- (void)cacheDataToSqite:(id)data type:(NSString *)type {
    NSString *dataString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
    MYIDatabase *db = [MYIDatabase sharedBatabase];
    [db creationSqlite];
    [db deleteDataType:type];
    [db insertType:type data:dataString];
}

//從sqlite中讀取數(shù)據(jù)
- (void)readDataForSqlite:(NSString *)type result:(void (^)(NSData *result))result {
    [[MYIDatabase sharedBatabase] creationSqlite];
    [[MYIDatabase sharedBatabase] dataType:type result:^(NSString *data) {
        if (result) {
            result([data dataUsingEncoding:NSUTF8StringEncoding]);
        }
    }];
}

                                                     }
                                                 }
                                             }];
                                         }];
