Question

iOS 5.0 SDK

I have a method that took a parameter as a ‘type’ that I defined. Lets call it ‘Places’. This type was defined as the following:

typedef enum {
    kBar = 0,
    kRestaurant = 1,
    kCafe = 2
} Places

My method would take a parameter of Places.

Based on the Place type passed in, I would append the type to the url:

ex: http://www.domain.com/place=1

However, the url parameter cannot be a number it has to be a string.

ex: http://www.domain.com/place=restaurant

I know enums cannot be strings so I am trying to figure out the right approach for this. Do I have a plist and then read the plist into a dictionary? Is there another way?

Answer 1

I would do something like:

typedef enum {
    PlaceTypeBar = 0,
    PlaceTypeRestaurant = 1,
    PlaceTypeCafe = 2
} PlaceType


@interface PlaceTypeHelper : NSObject
    + (NSString *) stringForPlace:(PlaceType)place;
@end

@implementation

+ (NSString *) stringForPlace:(PlaceType)place {
    NSArray *places = [NSArray arrayWithobjects:@"Bar", @"Restaurant", @"Cafe", nil];

   return [places objectForKey:(NSInteger)place];
}

@end

Headups, I’ve no tested the code yet.
