Question

I want to transport an array / NSArray of a particular container across a few methods from different classes. In C++, I’d use something like a Vector of structs.

The container could be represented in a struct like this:

struct test
{
    NSString * a;
    NSString * b;
    NSNumber * c;
}

The container basically needs to hold some strings and numbers.

Is there an alternative to using structs in Objective C? Is there some other “container” that I could use to send data?

Answer 1

I would recommend creating a simple object, something like this (compiled in my browser):

@interface Container : NSObject {
    NSString* a;
    NSString* b;
    NSString* c;
}

@property (retain) NSString* a;
@property (retain) NSString* b;
@property (retain) NSString* c;

@end


@implementation Container

@synthesize a, b, c;

- (void) dealloc {
    [a release];
    [b release];
    [c release];
    [super release];
}
@end
