Yesterday when I was making a label for my project I discovered that I can use two formats for displaying text on screen: 

label.text = @"Hello world";

And

NSString* textForLabel =[NSString stringWithFormat:@"Hello world"];
[label setText:textForLabel];

They both do the same thing.
Question - which one is better to use for app development and why?

StringwithFormat is used in those cases when dynamically you want to pass some value in string.

So if you just need to pass a string without need to pass any particular value in it then do not use stringwithformat.

The first one, because it's shorter, more obvious and it doesn't create a string from a string where that string isn't a format but incurs the processing cost of checking it as a format just to find it has no parameter insertion.

    the first one - in this particular case only. The second if you're building a string with parameters. – Russell Mar 09 '16 at 07:56
