// 1. 需要加入SystemConfiguration.framework、MobileCoreServices.framework、Security.framework三个框架// 2. 消除警告在pch文件中添加 #import #import// 3. 引入AFNetworking框架  #import "AFNetworking.h"// 4. 下面是详细代码，包括：简单网络请求、图片请求、JSON数据请求、XML数据请求、流媒体播放功能// 普通网络请求NSURL *url = [NSURL URLWithString:@"http://192.168.198.125/admin/index.php?m=interface&a=companies"];NSURLRequest *request = [NSURLRequest requestWithURL:url];// 准备AFHTTPRequestOperationAFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {    NSArray *array = operation.responseString;
