@interface NSArray<__covariant ObjectType> : NSObject <NSCopying, NSMutableCopying, NSSecureCoding, NSFastEnumeration> -->1.如果为基本数值类型,须要用NSNumber 封装为对象类型后,才能放入数组中。 NSInteger number=100; NSNumber *numberObject1= [NSNumber numberWithInteger:number ]; -->2.如果为C...
Deriving a class would entail copying this dispatch table and replacing the entries that you wanted to override, with your new "methods" having to call the original method if it wants to invoke the base method. Eventually, you end up rewriting C++. Share Improve this answer Follow answered ...

Typically, this means * copying any mutable objects that comprise the internal "deep structure" * of the object being cloned and replacing the references to these * objects with references to the copies. If a class contains only * primitive fields or references to immutable objects, then it ...
By convention, the object returned by this method should be independent of this object (which is being cloned). To achieve this independence, it may be necessary to modify one or more fields of the object returned bysuper.clonebefore returning it. Typically, this means copying any mutable obj...

The CLR garbage collector (GC) divides objects into small and large categories. When an object is large, some attributes associated with it become more significant than if the object is small. For instance, compacting it—copying the memory elsewhere on the heap—is expensive. In this mon...
