(kvoClass, aSel))); However, I encountered some issues. If I don't call the superclass's dealloc method in the cus_dealloc function, the superclass's dealloc implementation will not be executed. On the other hand, if I explicitly call the superclass's dealloc method, the program ...
So, with your class `L1` given, Swift generates `encode(to:)` and `init(from:)` automatically, which encodes and decodes all the properties in `L1`. By the way, Swift does not generate such a method or an initializer when they already exists, enabling users to customize the behavior ...
You can call methods on classes too, which is how you create objects. In the example below, we call the string method on the NSString class, which returns a new NSString object: 你也可以使用类直接调用方法。实际如在NSString类中直接调用string方法,返回一个NSString的对象: id myObject = [NS...
Every object has an instance variable calledisa. When an instance is created by sendingallocto a class, that class sets theisainstance variable of the returned object to point back at the class that created it (Figure 2.13). We call it theisapointer because an object “is a” instance of...
@implementation ZOCViewController - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { // call to the superclass designated initializer self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; if (self) { // Custom initialization (自定义的初始化过程) ...
CContainedWindowT allows you to create a new window by superclassing an existing window class. The Create method first registers a window class that is based on an existing class but uses CContainedWindowT::WindowProc. Create then creates a window based on this new window class. Each ...
关键字super用来指代上一个父类,可以用来调用父类的普通方法和构造方法。 注意:不能用来调用静态方法! 静态方法直接使用父类名调用即可。 子类调用父类的构造方法只能使用super,而不能使用构造方法名。 普通函数 super.toString(); Superclass.toString(); // 等价 构造函数 super(); // 正确 Superclass(); /...
