Question

I´m using this method to initialize an nsmutablearray

- (void)getAllContacts
{
Contact *contact = [[Contact alloc] init];
self.allContacts = [[NSMutableArray alloc] init];

int i=0;

for (i=0; i<5; i++) 
{
    contact.nome = [[NSString alloc] initWithFormat:@"Bruno %d", i];    
    [self.allContacts insertObject:contact atIndex:i];
    }
}

Pretty straightforward! But right after, i do a for to print it´s elements like:

for (int i=0; i<[self.allContacts count]; i++)
{
    Contact *c = [self.allContacts objectAtIndex:i];
    NSLog(@"i=%d\nNome:%@", i, c.nome);
} 

And it will show me 5 times the last element “Bruno 4”. It doesn´t start from 0 and increments. What should i do to start from 0?

Try this:

  - (void)getAllContacts
    {
    Contact *contact = nil;
    self.allContacts = [NSMutableArray array];

    int i=0;

    for (i=0; i<5; i++) 
    {
        contact = [Contact new];
        contact.nome = [NSString stringWithFormat:@"Bruno %d", i];    
        [self.allContacts addObject:contact];
        [contact release]
        }
    }
