• Run pod install.
• Include with #import "EAIntroView.h" to use it wherever you need.
• Subscribe to the EAIntroDelegate to enable delegate/callback interaction.

##Manual installation

• Include with #import "EAIntroView.h" to use it wherever you need.
• Subscribe to the EAIntroDelegate to enable delegate/callback interaction.

##How To Use It

Sample project have many examples of customization. Here are only simple ones.

###Step 1 - Build Pages Each page created with [EAIntroPage page] class method. Then you can customize any property, all of them are optional. Another approach is to pass your own (can be nib), custom view in EAIntroPage, this way most other options are ignored.

// basic
EAIntroPage *page1 = [EAIntroPage page];
page1.title = @"Hello world";
page1.desc = sampleDescription1;
// custom
EAIntroPage *page2 = [EAIntroPage page];
page2.title = @"This is page 2";
page2.titleFont = [UIFont fontWithName:@"Georgia-BoldItalic" size:20];
page2.titlePositionY = 220;
page2.desc = sampleDescription2;
page2.descFont = [UIFont fontWithName:@"Georgia-Italic" size:18];
page2.descPositionY = 200;
page2.titleIconView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"title2"]];
page2.titleIconPositionY = 100;
// custom view from nib
EAIntroPage *page3 = [EAIntroPage pageWithCustomViewFromNibNamed:@"IntroPage"];
page3.bgImage = [UIImage imageNamed:@"bg2"];

###Step 2 - Create Introduction View Once all pages have been created, you are ready to create the introduction view. Just pass them in right order in the introduction view. You can also pass array of pages after IntroView's initialization, it will rebuild its contents.

EAIntroView *intro = [[EAIntroView alloc] initWithFrame:self.view.bounds andPages:@[page1,page2,page3,page4]];

Don't forget to set the delegate if you want to use any callbacks.

[intro setDelegate:self];

###Step 3 - Show Introduction View

[intro showInView:self.view animateDuration:0.0];

###Storyboard/IB Since 1.3.0 EAIntroView supports init from IB. Since 2.0.0 EAIntroPage supports it too.

1. Drop UIView to your IB document.
2. Set its class to EAIntroView.
3. Create IBOutlet property in your view controller: @property(nonatomic,weak) IBOutlet EAIntroView *introView;.
4. Connect IBOutlet with EAIntroView in IB.
5. Build array of pages (you can use pageWithCustomViewFromNibNamed: here with separate nibs for each page).
6. Pass pages array to EAIntroView property in setPages:.
