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。

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 }
scaleAspectFit imageView.center = view.center return imageView }() override func viewDidLoad...() { super.viewDidLoad() view.addSubview(imageView) // iOS18新增 imageView.addSymbolEffect...scaleAspectFit imageView.center = view.center return imageView }() override func viewDidLoad...() { super.viewDidLoad() view.addSubview(imageView) // iOS18新增 imageView.addSymbolEffect...scaleAspectFit imageView.center = view.center return imageView }() override func viewDidLoad
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]; }
