Use user defined type (with typedef) as method parameter

Question

Hi

I've defined a new type with this code

typedef enum result 
{

     error,
     error1,
     erorr2,

}result;

After that I want to implement a method that takes a "result" as parameter

- (void) setError:(result)errorNumber

It seems that it is not allowed and give me an compiler error.

Is not possible to use user defined type as method parameters?!?

Answer 1

You need to import the header file that contains the typedef before you use it. For example:

File1.h:

typedef enum { a, b, c } resultType;

File2.h:

#import "File1.h"

...


- (void) someMethod:(resultType)param;

File1.h can be imported into as many header (or implementation) files as you need.
