Question

Ok so I populate the array like this:

NSMutableArray *participants;
for(int i = 0; i < sizeofpm; i++){
        NSDictionary *pmpart_dict = [pm_participants objectAtIndex:i];
        NSString *pmpart_email = [pmpart_dict objectForKey:@"email"];
        NSString *pmpart_email_extra = [@"pm" stringByAppendingString:pmpart_email];
        [participants setValue:pmpart_email forKey:pmpart_email_extra];
        NSLog(@"%@", participants);
    } 

sizeofpm is 1. that is using count. to get the number of values in the array. How can i store values to that array? It doesnt seem to be working. Thanks!

Answer 1

you need to alloc it first. Try to change the first line to:

NSMutableArray* participants = [[NSMutableArray alloc] init];

also using setValue:forKey: wont work with an NSMutableArray as an array has no key.

Try using [participants addObject:pmpart_email];.
