objective-c

I've been studying objective-c for a few days now. I keep coming across these two structures:

NSString * somestring
(NSString *) somestring

I understand the first simply sets a pointer to an NSString object, but what does the second construct do, and when should I use it? What's the deal with the asterix marks?

Sorry if this question doesn't make any sense, I am completely new to this language, and haven't even reached the level of asking proper questions.

Main purpose -- I'm trying to decipher this method:

-(NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger) row forComponent: (NSInteger)component

*Also, the classes I chose don't matter. *
