// RootViewController.m

使用方法:

ASIHttpRequst第三方类库不支持arc

使用前导入下面4个系统包

libz.1.1.3.dylib，MobileCoreServices.framework，SystemConfiguration.framework，CFNetwork.framework

#define URL_PATH @"http://sp.autohome.com.cn/clubapp/jingxuan/HomeJingHua.ashx?pageSize=20&pageIndex=0"

#import "RootViewController.h"

#import "ASIHTTPRequest.h"

@interface RootViewController ()

@end

@implementation RootViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil

{

self = [superinitWithNibName:nibNameOrNil bundle:nibBundleOrNil];

if (self) {

// Custom initialization

}

return self;

}

- (void)viewDidLoad

{

[superviewDidLoad];

// Do any additional setup after loading the view.

//ASI请求

[selfcreateASIHttp];

self.view.backgroundColor=[UIColorredColor];

}

-(void)createASIHttp{

//封装URL

NSURL *url=[NSURLURLWithString:URL_PATH];

//创建ASIHttp请求对象

ASIHTTPRequest *request=[ASIHTTPRequestrequestWithURL:url];

//协议

request.delegate=self;

//开始请求，开启异步请求

[request startSynchronous];

}

#pragma mark ASIHTTPRequestDelegate

-(void)requestStarted:(ASIHTTPRequest *)request{

NSLog(@"开始请求!");

}

-(void)request:(ASIHTTPRequest *)request didReceiveResponseHeaders:(NSDictionary *)responseHeaders{

NSLog(@"建立联系!");

}

-(void)requestFinished:(ASIHTTPRequest *)request{

// NSString *str=[[NSString alloc]initWithData:request.responseData encoding:NSUTF8StringEncoding];

// NSLog(@"%@",str);

//如若上面NSUTF8StringEncoding格式转换没用，链接的数据使用的GBK格式，所以data数据要格式转换

NSStringEncoding gbkEncoding =CFStringConvertEncodingToNSStringEncoding(kCFStringEncodingGB_18030_2000);

NSString *str=[[NSStringalloc]initWithData:request.responseDataencoding:gbkEncoding];

NSLog(@"%@",str);

}

- (void)didReceiveMemoryWarning

{

[superdidReceiveMemoryWarning];

// Dispose of any resources that can be recreated.

}
