Question

id        idPointer = [[SomeObject alloc] init];
NSObject *nsPointer = [[SomeObject alloc] init];

我如何获得<条码>idPointer和<条码>s Pointer的点码?

Answer 1

要让点人点到点,只需在变量上添加<条码>*。为了指派他们,你通常会找到一个正常的点子(&。然后在前面再次引用<代码>*。

//Declare and Assign them
id       *idPointerPointer = &idPointer;
NSObject **nsPointerPointer = &nsPointer;

//Dereference them (just an example to send a message)
[*idPointerPointer release];
[*nsPointerPointer release];
