Using storyboard this is very easy. You just drag the action to "Exit". But how should I call it from my code?

Create a manual segue (ctrl-drag from File’s Owner to Exit),
Choose it in the Left Controller Menu below green EXIT button.

Choose it in the Left Controller Menu below green EXIT button

Go to Targets in Xcode.
Build Settings on your project's target (your current development name).
Search for Product Name under Packaging. Change its value to what you want your new project name to be.

Ios – Constants in Objective-C

You should create a header file like

// Constants.h
FOUNDATION_EXPORT NSString *const MyFirstConstant;
FOUNDATION_EXPORT NSString *const MySecondConstant;
//etc.

(you can use extern instead of FOUNDATION_EXPORT if your code will not be used in mixed C/C++ environments or on other platforms)

You can include this file in each file that uses the constants or in the pre-compiled header for the project.

You define these constants in a .m file like

// Constants.m
NSString *const MyFirstConstant = @"FirstConstant";
NSString *const MySecondConstant = @"SecondConstant";

Constants.m should be added to your application/framework's target so that it is linked in to the final product.

The advantage of using string constants instead of #define'd constants is that you can test for equality using pointer comparison (stringInstance == MyFirstConstant) which is much faster than string comparison ([stringInstance isEqualToString:MyFirstConstant]) (and easier to read, IMO).
