Exponents in NSString

问题

Is it possible to have exponents in an NSString object that will be displayed in a UITextField and a UILabel? If so, how do we do it? If not, any alternatives you might suggest?

As answered by jrturton in this question:

You need to include the unicode symbol for a superscripted character:

NSInteger number = 10; 
NSString *cubedSymbol = @"\u00B3";
NSString *tenCubed = [NSString stringWithFormat:@"%d%@",number,cubedSymbol];

Plenty more fun is to be had here
