AFNetworking 2.0 使用

AFNetworking 下载地址：https://github.com/AFNetworking/AFNetworking/

AFNetworking 2.0 当Deployment Target 低于6.0时，AFURLConnectionOperation.h,AFURLSessionManager.h

@property (nonatomic, strong) dispatch_queue_t completionQueue;

由于sdk低于6.0时，dispatch_queue_t  ARC没有托管，出现提示错误

 Property with 'retain (or strong)' attribute must be of object type

修改为

#if OS_OBJECT_USE_OBJC
@property (nonatomic, strong) dispatch_queue_t completionQueue;
#else
@property (nonatomic, assign) dispatch_queue_t completionQueue;
#endif

 

使用示例：(不使用官方的自带的json和xml解析，返回NSData)

1.0兼容版

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    manager.responseSerializer = [AFHTTPResponseSerializer serializer];
    [manager GET:@"http://www.com" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {

    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {

    }];

 2.0

    AFHTTPSessionManager *httpSessionManager =[AFHTTPSessionManager manager];
    httpSessionManager.responseSerializer = [AFHTTPResponseSerializer serializer];
    NSURLSessionDataTask *task = [httpSessionManager GET:@"http://www.com" parameters:nil success:^(NSURLSessionDataTask *task, id responseObject)
    {

    } failure:^(NSURLSessionDataTask *task, NSError *error)
    {
        
    }];

 

IOS SDK 4.3以上兼容版,需要使用AFNetworking-0.10.x版本

    AFHTTPClient *httpClient = [AFHTTPClient clientWithBaseURL:nil];
    [httpClient getPath:@"http://www.com" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject)
     {

     } failure:^(AFHTTPRequestOperation *operation, NSError *error)
     {

     }];
