Question

I want to add string objects to an array inside for loop. Below is my code;

for (int i=0;i<[retrievedArray count];i++)
{
    NSString *temp = [[retrievedArray objectAtIndex:i] OfficialName];
    [detailPgArray addObject:temp];
}

I have 10 objects inside retrievedArray (not as direct strings, but as OfficialName)

But for some reason, at the end of the for loop, detailPgArray has 0 objects. Please help.

detailPgArray is more than likely nil. You need to allocate somewhere. If it is an instance variable try the following.

[detailPgArray release];
detailPgArray = [[NSMutableArray alloc] initWithCapacity:[retrievedArray count]];

for (int i=0;i<[retrievedArray count];i++)
{
    NSString *temp = [[retrievedArray objectAtIndex:i] OfficialName];
    [detailPgArray addObject:temp];
}
