Models: UserModel.swift

Views: UserInfoCell.swift

Controllers: RootViewController.swift,DetailViewController.swift

AppDelegate.swift:

 self.window!.rootViewController=rootNav
 self.window!.backgroundColor=UIColor.whiteColor()
 self.window!.makeKeyAndVisible()
 returntrue
 }
 }

UserModel.swift

RootViewController.swift:

 }

DetailViewController.swift:

copy

 //changeItemneedstoadda?totheend,before(),because
 //thisfunctionisoptional
 //delegate?表示可能没有代理，而changeItem?表示方法可能没有实现，这样写就算没有实现也没有问题
 delegate?.changeItem?(forUserModel:userModel)
