ASIHTTPRequest同步请求数据

同步请求数据
简介:
新建一个textView,用他来接收请求到的数据.
//新建tv
    tv = [[UITextView alloc] initWithFrame: CGRectMake(0, 30, 320, 300)];
    tv.text = @"";
   
//使用asi同步请求数据
    NSURL *url = [NSURL URLWithString:@"http://www.baidu.com"];
    ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
    [request startSynchronous];
    
    NSError *error = [request error];
    if (!error)
    {
        // Call this method to get the received data as an NSString. Don't use for binary data!
        NSString *response = [request responseString];
        
//添加数据到tv中显示
        tv.text =  [NSString stringWithString: response];

//显示图片
UIImageView *image = [[UIImageView alloc] initWithImage: [UIImage imageWithData: response]]; 
        image.frame = CGRectMake(0, 50, 100, 50); 
        
        [self.window addSubview: image];  
     
    }
