ASIHttpRequest框架使用

要使用ASIRequest必须添加5个动态库，CFNetwork.framework、SystemConfigureation.framework、MobileCoreServices.framework、libz.dylib和libxml2.dylib

    ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
    [request setRequestMethod:@"GET"];
    [request setTimeOutSeconds:60];
    // 设置请求头
    // [request setRequestHeaders:<#(NSMutableDictionary *)#>]
    // 设置cookies
    // [request setRequestCookies:<#(NSMutableArray *)#>]
    // 发送同步请求
    [request startSynchronous];
    NSError *error = request.error;
    if (error == nil) {
        NSData *data = request.responseData;
        UIImage  *img = [UIImage imageWithData:data];
        NSLog(@"%@", data);
        self.image = img;
    } else {
        NSLog(@"请求网络出错:%@", error);
    }

如果出现编译出错
