Question

afnetworking可以解析json吗

Answer 1

目前我只是用到
#import “AFHTTPClient.h”;
#import “AFHTTPRequestOperation.h”
这两个类
发起一个请求

NSString *URLTmp = @”http://www.coneboy.com”;
NSString *URLTmp1 = [URLTmp stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; //转码成UTF-8 否则可能会出现错误
URLTmp = URLTmp1;
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString: URLTmp]];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@”Success: %@”, operation.responseString);

NSString *requestTmp = [NSString stringWithString:operation.responseString];
NSData *resData = [[NSData alloc] initWithData:[requestTmp dataUsingEncoding:NSUTF8StringEncoding]];
//系统自带JSON解析
NSDictionary *resultDic = [NSJSONSerialization JSONObjectWithData:resData options:NSJSONReadingMutableLeaves error:nil];
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@”Failure: %@”, error);
[SVProgressHUD dismissWithError:@”提交失败，请重试”];
}];
[operation start];
}

AFNetworking 下载图片
AFNETWorking 下载图片是异步并且可缓存到cache里面 非常好用不会阻塞主线程。用过的都说好！而且使用也简单！
#import “UIImageView+AFNetworking.h”

[imageView setImageWithURL:[NSURL URLWithString:URL]];
