在其他类中调用即可，例如：
- (void)viewDidLoad {
[super viewDidLoad];
NSString* url=@"http://ipad-bjwb.bjd.com.cn/DigitalPublication/publish/Handler/APINewsList.ashx?date=20151101&startRecord=1&len=5&udid=1234567890&terminalType=Iphone&cid=213";
[NetWorkingHelper requestWithType:GET url:url parameters:nil success:^(NSURLSessionTask *task, id responseObject) {

NSLog(@"请求成功----%@",responseObject);
}
} failure:^(NSURLSessionTask *task, NSError *error) {
if (error) {
NSLog(@"请求失败---%@",error.description);
}
}];
}
