I have a JSONModel class in Objective-C. I am initializing this with JSON returned by a server. 

#import "JSONModel.h"

@protocol MyJsonMoodelClass

@end

@interface MyJsonMoodelClass : JSONModel

@property (nonatomic, strong)  NSNumber <Optional>  * idFilm;

This JSON contains a variable called idFilm, and sometimes is returned of type NSNumber but another is returned in array.

For exaple:

idFilm : 5

or

idFilm : [2, 5]

How could I control this and how could I have the same variable defined by two types, NSNumber and NSArray? Is possible control this?

    You could set it to an NSObject which is superclass of both NSNumber and NSArray. But this is not really a good idea in most situations as you'd always have to be checking which type it is before doing anything with it (`isKindOfClass`), and it doesn't naturally convert to JSON, in your case, without extra work. Better would be to always use an array, and if you get a number, put that number in an array and use the array instead (ie, an array with only one element). – Son of a Beach Dec 22 '16 at 01:16

if you override "set" method? something like this:

- (void)setIdFilm:(id)idFilm
{
    if([idFilm isKindOfClass:NSArray])
        ...
    else
        ...
}

I don't know if can work but can be a starting point
