Who can explain why in Objective-C sometimes are used this to my mind strange variable names like 

NSArray * _sushiTypes;
NSString * _lastSushiSelected;

or sometimes 

NSArray * sushiTypes = _sushiTypes;
NSString * lastSushiSelected = _lastSushiSelected;

Is there any necessity for this?

    Some people think that it's cool. They're wrong. That's it. (Also, you have to distinguish between local and instance variables - this is a valid convention in the case of instance variables in order to denote them being private.) –  Mar 29 '13 at 06:03

    @ShurupuS The `_` symbol is called the "underscore". – rmaddy Mar 29 '13 at 06:19
