  6. NSString Class Reference https://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Foundation/Classes/NSString_Class/Reference/NSString.html • The NSString class declares the programmatic interface for an object that manages immutable strings. An immutable string is a text string that is defined when it is created and subsequently cannot be changed. NSString is implemented to represent an array of Unicode characters, in other words, a text string. • NSString class contains 146 methods. • stringWithFormat: Returns a string created by using a given format string as a template into which the remaining argument values are substituted. + (id)stringWithFormat:(NSString *)format,...

  7. UILabel Class Reference • The UILabel class implements a read-only text view. You can use this class to draw one or multiple lines of static text, such as those you might use to identify other parts of your user interface. • See below for detail: https://developer.apple.com/library/ios/#documentation/UIKit/Reference/UILabel_Class/Reference/UILabel.html
