精彩摘录
- "在便捷方法中，应该使用 self，而不是直接使用类名，这样子类也能使用同一个方法。"
- "All Objective-C objects are stored in a part of memory called the heap. When we send an alloc message to a class, a chunk of memory is allocated from the heap. This chunk includes space for the object’s instance variables. Pointer variables convery ownership of the objects that they point to. 1. Whe"
- "How objects lose owners 1. A variable that points to the object is changed to point to another object. 2. A variable that points to the object is set to nil. 3. A variable that points to the object is itself destroyed. A pointer variable stores the address of an object, that object has an owner and "
- "Build and run the application again. This time, the objects are destroyed properly. Every retain cycle can be broken down into a parent-child relationship. A parent typically keeps a strong reference to its child, so if a child needs a pointer to its parent, that pointer must be a weak reference to "
- "A property is declared in the interface of a class where methods are declared. A property declaration has the following form: @property NSString *itemName; When you declare a property, you are implicitly declaring a setter and a getter for the instance variable of the same name. So the above line of"
- "Delegation is an object-oriented approach to callbacks. A callback is a function that is supplied in advance of an event and is called every time that event occurs. Some objects need to make a callback for more than one event. For instance, the location manager wants to "callback" when it finds a ne"
- "A view is an instance of UIView or one of its subclasses. A view knows how to draw itself on the application’s window, an instance of UIWindow. A view exists within a hierarchy of views. The root of this hierarchy is the application’s window. A view handles events, like touches. Core Graphics CGCont"
- "Instances of UIResponder can become the first responder of the window and will receive nevents when the device is shaken or a key is pressed on the keyboard."
