方法前面的 +/- 号代表函数的类型:加号(+)代表类方法(class method),不需要实例就可以调用,与C++ 的静态函数(static member function)相似。减号(-)即是一般的实例方法(instance method)。 这里提供了一份意义相近的C++语法对照,如下: classMyObject:publicNSObject{protected:intmemberVar1;// 实体变量void*membe...
Comparing pointers using the equality operators==and!=has well-defined semantics regardless of whether or not either of the pointers is null, points into the same object, or points one past the last element of an array object or function. ...

When calling the CDeferredCommand::Invoke member function, the calling application gets an interface pointer that is reference-counted, and the CCmdQueue object also holds a reference count on the deferred command. Calling the IDeferredCommand::Cancel member function takes the deferred command off ...
