AFNetworking第三方封装

https://github.com/AFNetworking/AFNetworking将第三方库，添加到工程#import "AFNetworking.h" NSMutableDictionary *dic = [NSMutableDictionary dictionary];    [dic setObject:@"1" forKey:@"pageindex"];    [dic setObject:@"1" forKey:@"pagesize"];    [dic setObject:@"上海" forKey:@"keyword"];    [dic setObject:@"79396f95d9bf1e813672358f2890cfa7" forKey:@"key"];#pragma mark - AfnetWorking第三方网络请求    AFHTTPRequestOperationManager *maneger = [AFHTTPRequestOperationManager manager];    [maneger POST:@"http://api2.juheapi.com/xiecheng/senicspot/ticket/search" parameters:dic success:^(AFHTTPRequestOperation *operation, id responseObject) {        NSLog(@"%@",responseObject);    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {        NSLog(@"error reason:%@",error.localizedDescription);    }];
