Array of pointers in Objective-C using NSArray
- by Amir
Hello,
I am writting program for my iphone and have a qestion.
lets say i have class named my_obj
class my_obj
{
NSString *name;
NSinteger *id;
NSinteger *foo;
NSString *boo;
}
now i allocate 100 objects from type my_obj and insert them to array from type NSArray.
then i want to sort the Array in two different ways. one by the name and the second by
the id.
i want to allocate another two arrays from type NSArray
*arraySortByName
*arraySortById
what i need to do if i just want the sorted arrays to be referenced to the original array
so i will get two sorted arrays that point to the original array (that didnt changed!)
i other word i dont want to allocate another 100 objects to each sorted array.
