##Sliding Tutorial iOS 
###Simple library that helps developers to create awesome sliding iOS app tutorial.
Applied parallax effects will make your product presentation look like Google apps tutorial.
All you need to do is:
1. Create icons for each screen of your tutorial
2. Follow the instructions below
Add to your Podline a line
pod 'SlidingTutorial'
Run in terminal command
$ pod install
Then import PRLView.h to your view controller:
#import "PRLView.h"
After you should instantiate an instance of sliding view tutorial class:
PRLView *viewParallax = [[PRLView alloc] initWithPageCount:3 scaleCoefficient:0.8];
Where first parameter is a count of pages in tutorial and second parameter is a coefficient of scaling images (put 1.0 if you don't need scale and images will displaying in a full size).
Then add background colors for all your tutorial pages:
[viewParallax addBackgroundColor:[UIColor colorWithRed:231./255 green:150./255 blue:0 alpha:1]];
[viewParallax addBackgroundColor:[UIColor colorWithRed:163./255 green:181./255 blue:0 alpha:1]];
[viewParallax addBackgroundColor:[UIColor colorWithRed:35./255 green:75./255 blue:122.0/255 alpha:1]];
The colors follow the order they are added. All missing colors will be replaced with white color.
After that you should add all image-layers onto sliding tutorial view:
[viewParallax addElementWithName:@"elem00-00" offsetX:0 offsetY:0 slippingCoefficient:0.3 pageNum:0];
[viewParallax addElementWithName:@"elem01-00" offsetX:-140 offsetY:25 slippingCoefficient:-0.15 pageNum:1];
[viewParallax addElementWithName:@"elem02-00" offsetX:-50 offsetY:-120 slippingCoefficient:0.2 pageNum:2];
First param - image name from your project resources.
offsetX and offsetY - layer offset from the center of the screen. If you send offsetX:0 offsetY:0 your image layer will be placed exactly in the center of the screen. Dot (0,0) in this coords system situated in the center of the screen in all device orientations.
slippingCoefficient - ratio bound to scroll offset in scroll view. For 1 pixel content offset of scroll view layer will be slipping for 1 * slippingCoefficient (so if slippingCoefficient == 0.3, it will be equal 0.3px). Sign determines the direction of slipping - left or right.
pageNum - the page number on which you will add this image layer.
After all call last method - prepareForShow:
[viewParallax prepareForShow];
And now your tutorial is ready to show.
For handle skip button action, you should support PRLViewProtocol and implement protocol method skipTutorial
