Can I use short code when initialize?

I have a very simple question. When I read iPad programming guide, there are a lot of similar codes as below:

Code:

NSString *str =  [[NSString alloc] initWithFormat:@"Row is %d", row];
cell.textLabel.text = str;
[str release];

I want to know if I can use code as below:

Code:

cell.textLabel.text = [[NSString alloc] initWithFormat:@"Row is %d", row]

 

Thanks for your answer.

I also read what you suggested, maybe my English is not good enough, I am not sure about that so I want to confirm it.

 

Thanks, this one is better!
