I have a very basic question. I'm a new iPhone programmer. My question is can anybody tell me how can I pass values by reference to a function in obj. C? I know how to do it in VB and C#. But don't know how to do it in Obj c.

Thanks

There's an argument to be had if you want to get more than one address from a resulting function call. You can do so instead by creating a wrapper class and passing that instead. For example:

@interface AddressWrapper : NSObject {
    NSArray     *array;
    NSString    *string;
}

@property (nonatomic, assign)   NSArray *array;
@property (nonatomic, assign)   NSString *string;
@end

In *.m:

@implementation AddressWrapper
@synthesize array, string;
@end



-(void) getAddresses: (AddressWrapper*) wrapper {
    wrapper.array = myNSArray;
    wrapper.string = myNSString;
}
