Question

I want to store tuples of 2 ints and a char in an NSArray.
Is there an easyer way than to declare an class holding the 2 ints and the char?

I tryed it this way and it works, but it seems rather complicated to me. Is there a better and easyer way?

@interface Container : NSObject
@property  NSInteger a;
@property  NSInteger b;
@property  char      c;
@end

@implementation Container
@synthesize a = _a;
@synthesize b = _b;
@synthesize c = _c;

-(Container*) initWitha:(NSInteger) a andB:(NSInteger) b andC: (char) c
{
    if ((self = [super init])) {
        self.a = a;
        self.b = b;
        self.c = c;
    }
    return self;
}  
@end

...
//usage

NSMutableArray *array = [[NSMutableArray alloc] init];
[array addObject: [[Container alloc] initWitha:5 andB:6 andC:'D']];

Thanks

Maybe you could just use a C struct ?

struct Container {
    NSInteger a; // If you're using char c, why not use int a?
    NSInteger b;
    char c;
};

then you could do something like

struct Container c;

NSMutableArray *array = [[NSMutableArray alloc] initWithCapacity:1]

// Insert
[array addObject:[NSValue value:&c withObjCType:@encode(struct Container)]];

// Retrieve:
struct Container c;
[[array objectAtIndex:i] getValue:&c];
