Objective C convert number to NSNumber

Question

Why doesn\'t this please the compiler? Casting is supposed to work like in C as I can read here How to cast an object in Objective-C.

[p setAge:(NSNumber*)10         


        

Answer 1

Use this:

[p setAge:[NSNumber numberWithInt:10]];

You can't cast an integer literal like 10 to a NSNumber* (pointer to NSNumber).
