objective c - How do you store "int" values in an NSMutableArray* or NSMutableDictionary*? Chronic problems with JSON data that come in as integers.

Question

How do you store "int" values in an NSMutableArray or NSMutableDictionary? Chronic problems with JSON data that come in as integers.

Should I try to store these integers as NSNumber objects or just as strings that contain the integer?

How dangerous is it to do a "raw" (int) conversion on the pointers if I know the values will always be Natural Numbers (numbers>=0 including zero for null.)

The integers I'm always working with are Foreign Key Id's from a database.

Answer 1

Use NSNumber like this:

int yourInt = 5;
[myMutableArray addObject:[NSNumber numberWithInt:yourInt]];

Or using modern Objective C syntax, you can use the following for expressions:

[myMutableArray addObject:@(2 + 3)];

Or for lone numbers:

[myMutableArray addObject:@5];
