ios 防止app被抓包（判断网络请求是否设置了代理）

判断ios app是否被抓包了（抓包工具是charles或是fiddler目前不知道怎么获取）

导入系统框架 获取系统代理设置 

可获取到代理服务器的地址、端口号、链接类型（http || https）

获取到app被抓包可以进行终止数据传输

    if ([[settings objectForKey:(NSString *)kCFProxyTypeKey] isEqualToString:@"kCFProxyTypeNone"]){

        //没有设置代理

        returnNO;

    }else{

        //设置代理了

        returnYES;
