Object-C开发教程--如何在项目中使用AFNetworking

AFNetworking 是 iOS 一个使用很方便的网络开发框架。今天我们就简单介绍如何在我们的项目中使用它。

1、从官网下载最新的AFNetworking代码。

2、将AFNetWorking和UIKit+AFNetworking文件夹导入项目
3、添加类库 Security.framework、MobileCoreServices.framework、SystemConfiguration.framework
4、在使用的地方导入

#import AFNetworking.h

#import UIKit+AFNetworking.h

5、网络url访问测试。

NSString *URLTmp = @https://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];

NSLog(@success:%@,resultDic);

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

NSLog(@Failure: %@, error);

//[SVProgressHUD dismissWithError:@提交失败，请重试];

}];

[operation start];

6、如何获取一张网络图片

 

NSString *url = @https://www.uimaker.com/uploads/allimg/111101/1_111101085050_3.jpg;

UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(10.0f, 150.0f, 200.0f, 200.0f)];

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

[self.view addSubview:imageView];
