網(wǎng)上也有很多的對(duì)AFNetworking進(jìn)行封裝的方法，此處我只是簡(jiǎn)單的記錄一下；

首先，我們創(chuàng)建一個(gè)繼承與NSObject的類(lèi)，定義兩個(gè)屬性，分別是請(qǐng)求成功和請(qǐng)求失敗的，.h中的代碼如下：

#import <Foundation/Foundation.h>

typedef void (^SuccessBlock)(NSDictionary *data);
typedef void (^FailureBlock)(NSError *error);

@interface SYNetworkingManager : NSObject

@property (nonatomic, copy) SuccessBlock successBlock;
@property (nonatomic, copy) FailureBlock failureBlock;

/**
 *  發(fā)送get請(qǐng)求
 *
 *  @param URLString  請(qǐng)求的網(wǎng)址字符串
 *  @param parameters 請(qǐng)求的參數(shù)
 *  @param success    請(qǐng)求成功的回調(diào)
 *  @param failure    請(qǐng)求失敗的回調(diào)
 */
+ (void)getWithURLString:(NSString *)urlString
              parameters:(id)parameters
                 success:(SuccessBlock)successBlock
                 failure:(FailureBlock)failureBlock;

/**
 *  發(fā)送post請(qǐng)求
 *
 *  @param URLString  請(qǐng)求的網(wǎng)址字符串
 *  @param parameters 請(qǐng)求的參數(shù)
 *  @param success    請(qǐng)求成功的回調(diào)
 *  @param failure    請(qǐng)求失敗的回調(diào)
 */
+ (void)postWithURLString:(NSString *)urlString
               parameters:(id)parameters
                  success:(SuccessBlock)successBlock
                  failure:(FailureBlock)failureBlock;

@end

.m中的實(shí)現(xiàn)如下：

+ (void)getWithURLString:(NSString *)urlString
              parameters:(id)parameters
                 success:(SuccessBlock)successBlock
                 failure:(FailureBlock)failureBlock
{
    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    /**
     *  可以接受的類(lèi)型
     */
    manager.responseSerializer = [AFHTTPResponseSerializer serializer];
    /**
     *  請(qǐng)求隊(duì)列的最大并發(fā)數(shù)
     */
    //    manager.operationQueue.maxConcurrentOperationCount = 5;
    /**
     *  請(qǐng)求超時(shí)的時(shí)間
     */
    manager.requestSerializer.timeoutInterval = outTime;
    [manager GET:urlString parameters:parameters progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        if (successBlock) {
            NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableLeaves error:nil];
            successBlock(dic);
        }
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        if (failureBlock) {
            failureBlock(error);
            NSLog(@"網(wǎng)絡(luò)異常 - T_T%@", error);
        }
    }];
}

+ (void)postWithURLString:(NSString *)urlString
               parameters:(id)parameters
                  success:(SuccessBlock)successBlock
                  failure:(FailureBlock)failureBlock
{
    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    manager.responseSerializer = [AFHTTPResponseSerializer serializer];
    manager.requestSerializer.timeoutInterval = outTime;
    [manager POST:urlString parameters:parameters progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        if (successBlock) {
            NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingMutableLeaves error:nil];
            successBlock(dic);
        }
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        if (failureBlock) {
            failureBlock(error);
            NSLog(@"網(wǎng)絡(luò)異常 - T_T%@", error);
        }
    }];
}

以上只是對(duì)post和get請(qǐng)求的封裝，如果有好的建議和好的文章，我很樂(lè)意學(xué)習(xí)！
