Conventions

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.

Code words in text are shown as follows: "In AppDelegate.h file, find the application:didFinishLaunchingWithOptions: method and where we are registering for push notifications."

A block is set of code will be shown as follows:

SKAction *sequence = [SKAction sequence:@[[SKAction rotateByAngle:degreeToRadian(-3.0f) duration:0.2],[SKAction rotateByAngle:0.0 duration:0.1],[SKAction rotateByAngle:degreeToRadian(3.0f) duration:0.2]]];
[touchedNode runAction:[SKAction repeatActionForever:sequence]];

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Select a location on the drive to save the project and click on Create."
