AFHTTPSessionManager 的封装使用

1.首先创建单体类

#import "AFHTTPSessionManager.h"

@interface SXNetworkTools : AFHTTPSessionManager
+ (instancetype)sharedNetworkTools;
@end



#import "SXNetworkTools.h"
@implementation SXNetworkTools
+ (instancetype)sharedNetworkTools
{
    static SXNetworkTools*instance;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        
        // http://c.m.163.com//nc/article/list/T1348649654285/0-20.html
        // http://c.m.163.com/photo/api/set/0096/57255.json
        // http://c.m.163.com/photo/api/set/54GI0096/57203.html
        NSURL *url = [NSURL URLWithString:@"http://c.m.163.com/"];
        //设置会话
        NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration];
        //创建会话
        instance = [[self alloc]initWithBaseURL:url sessionConfiguration:config];
        //设置接收文件的格式
        instance.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript", @"text/html", nil];
    });
    return instance;
}

@end

调用get和pos方法

- (NSURLSessionDataTask *)GET:(NSString *)URLString
                   parameters:(id)parameters
                      success:(void (^)(NSURLSessionDataTask *task, id responseObject))success
                      failure:(void (^)(NSURLSessionDataTask *task, NSError *error))failure
{}


- (NSURLSessionDataTask *)POST:(NSString *)URLString
                    parameters:(id)parameters
                       success:(void (^)(NSURLSessionDataTask *task, id responseObject))success
                       failure:(void (^)(NSURLSessionDataTask *task, NSError *error))failure
{}

 

使用方法

 [[[SXNetworkTools sharedNetworkTools]GET:allUrlstring parameters:nil success:^(NSURLSessionDataTask *task, NSDictionary* responseObject) {
        NSLog(@"%@",allUrlstring);
        NSString *key = [responseObject.keyEnumerator nextObject];
        
        NSArray *temArray = responseObject[key];
        
        NSMutableArray *arrayM = [NSMutableArray arrayWithCapacity:temArray.count];
        [temArray enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
            
            SXNewsModel *news = [SXNewsModel newsModelWithDict:obj];
            [arrayM addObject:news];
        }];
        if (type == 1) {
            self.arrayList = arrayM;
            [self.tableView headerEndRefreshing];
            [self.tableView reloadData];
        }else if(type == 2){
            [self.arrayList addObjectsFromArray:arrayM];
            //        NSLog(@"%ld",self.arrayList.count);
            [self.tableView footerEndRefreshing];
            [self.tableView reloadData];
        }
        
    } failure:^(NSURLSessionDataTask *task, NSError *error) {
        NSLog(@"%@",error);
    }] resume];
