ios - pointer in Objective-C -


I am learning iOS for several months, I think I use the pointer Should have many object-type objects.
But there are some cases that should not use indicators such as "NSInteger" "CGPoint" "BOOL" ... ... so the question is, what conditions do I suggest? And what is the purpose of using the indicator indicator

NSIFFER, CG points, etc. Objective-Objects are not They are Straits or Type Fif.

You have to use pointers with the object type. You can use Pointer with other (C) type
