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 = @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];
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.cppentry.com/upload_files/article/45/1_y20gh__.jpg;
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(10.0f, 150.0f, 200.0f, 200.0f)];
[imageView setImageWithURL:[NSURL URLWithString:url]];
[self.view addSubview:imageView];
