//视图控制器//当一个视图控制器被创建，并在屏幕上显示的时候。 代码的执行顺序
//1、 alloc 创建对象，分配空间
//2、init (initWithNibName) 初始化对象，初始化数据
//3、loadView 从nib载入视图 ，通常这一步不需要去干涉。除非你没有使用xib文件创建视图
//4、viewDidLoad 载入完成，可以进行自定义数据以及动态创建其他控件
//5、viewWillAppear 视图将出现在屏幕之前，马上这个视图就会被展现在屏幕上了
//6、viewDidAppear 视图已在屏幕上渲染完成
//当一个视图被移除屏幕并且销毁的时候的执行顺序，这个顺序差不多和上面的相反
//1、viewWillDisappear 视图将被从屏幕上移除之前执行
//2、viewDidDisappear 视图已经被从屏幕上移除，用户看不到这个视图了
//3、dealloc 视图被销毁，此处需要对你在init和viewDidLoad中创建的对象进行释放- (void)loadView
