Objective-C loop through array

Question

I have code similar to this

if (count == 0)
{
    [array1 addObject:@"No Items"];
} 
else
{
    int x;
    for (x = 0;x <= count; x++) 
    {
            [array1 addObject:[itemsArray objectAtIndex:x];
            NSLog(@"%@",array1);
    }
}

itemsArray has numbers in it (0-40). My expected result is:

• 1
• 2
• 3
• ...

However it actually does:

• 1
• 1,2
• 1,2,3
• 1,2,3,4
• 1,2,3,4,5
• ...

Why does this happen? If possible, I'd also like to ask for an example to use fast enumeration for this situation (if it suits for this).

Thanks in advance.

Solution 1

You are NSLoging the whole array, not the current index of array1. What you are seeing logged is what you've coded - to log what you are expecting, change NSLog(@"%@",array1); to NSLog(@"%@",[array1 objectAtIndex:x]);

To confirm add the following after your assignment loop:

for (NSObject* o in array1)
{
    NSLog(@"%@",o);
}

Solution 2

Use NSLog(@"%@", [array1 objectATIndex:x]);

if (count == 0)
{
    [array1 addObject:@"No Items"];
} 
else
{
    int x;
    for (x = 0;x <= count; x++) 
    {
            [array1 addObject:[itemsArray objectAtIndex:x];
            NSLog(@"%@", [array1 objectATIndex:x]);
    }
}
