viewDidLoad 此方法只有当view从nib文件初始化的时候才被调用。 loadView 此方法在控制器的view为nil的时候被调用。 此方法用于以编程的方式创建view的时候用到。
加载通过 XIB 自定义 View 的加载我们一般会有如下方法 XIBView: ZYXIBTestView.xib 在需要使用的 VC: override func viewDidLoad() {...super.viewDidLoad() let view = Bundle.main.loadNibNamed("ZYXIBTestView", owner: nil, options:...ZYXIBTestView } 使用的时候： override func viewDidLoad() { super.viewDidLoad() let view = ZYXIBTestView.initByNib...() { super.viewDidLoad() let view = ZYXIBTestView.initNib(by: ZYXIBTestView.self) } 可是看起有点怪怪的...- (void)viewDidLoad { [super viewDidLoad]; UIView *view = [ZYXIBTestView initByNib]; }
创建三个视图控制器：FirstViewController、SecondViewController和ThirdViewController 2、修改FirstViewController.swift的viewDidLoad...override func viewDidLoad() { super.viewDidLoad() self.view.backgroundColor = UIColor.brown self.navigationItem.rightBarButtonItem...UIBarButtonItemStyle.Plain, target：self, action： selector(FirstViewController.nextPage)) } 3、 SecondViewController.swift的viewDidLoad...override func viewDidLoad() { super.viewDidLoad() self.view.backgroundColor = UIColor.purple }
override func viewDidLoad() { super.viewDidLoad() nameObserver = NSNotificationCenter.defaultCenter...deinit { print("dealloced") // 析构方法永远不会被执行 } override func viewDidLoad() { super.viewDidLoad...deinit { print("dealloced") // 这样就可以走到析构方法了 } override func viewDidLoad() {...super.viewDidLoad() weak var welf = self nameObserver = NSNotificationCenter.defaultCenter...nameObserver) // 那我们就把它释放掉好了 } print("dealloced") // 这样就可以走到析构方法了 } override func viewDidLoad

控制器View的创建 首先我们来看一下控制器view创建的流程图 控制器view加载.jpeg 从图中我们可以看出，在控制器view加载过程中有两个重要的方法loadView和viewDidLoad。...viewDidLoad 作用：一般我们会在这里做界面上的初始化操作，比如往view中添加一些子视图等。 什么时候调用：每当view创建完毕的时候，最终都会调用viewDidLoad方法。...控制器View的生命周期 控制器View的生命周期方法 loadView： 加载view viewDidLoad： view...{ [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib....方法，loadView中将view设置为绿色，viewDidLoad方法中又将view设置成蓝色，但是最后被vc.view.backgroundColor = [UIColor redColor];设置为红色
