创建桥接文件 导入3.0
创建RecipeResultViewController,RecipeViewController,,XiangQingViewController, 继承uiviewcontroller 进行跳转
创建URLService 继承NSObject 创建 Recipe
.plist中 App Transport Security Settings 加Allow Arbitrary Loads
在AppDelegate中
letdenglu = dengluViewController()
//登录
denglu.navigationItem.title = ""
let nav1 = UINavigationController.init(rootViewController: denglu)
self.window?.rootViewController = nav1
