Installation

You can setup EAIntroView using Carthage, CocoaPods or completely manually.

Carthage

Add EAIntroView to your project's Cartfile:
```
github "ealeksandrov/EAIntroView"
```
Run carthage update in your project directory.
On your application targets’ “General” settings tab, in the “Linked Frameworks and Libraries” section, drag and drop EAIntroView.framework and EARestrictedScrollView.framework from the Carthage/Build/iOS/ folder on disk.

On your application targets’ “Build Phases” settings tab, click the “+” icon and choose “New Run Script Phase”. Create a Run Script with the following contents:

/usr/local/bin/carthage copy-frameworks

add the paths to the frameworks under “Input Files”:

$(SRCROOT)/Carthage/Build/iOS/EAIntroView.framework
$(SRCROOT)/Carthage/Build/iOS/EARestrictedScrollView.framework

and the paths to the copied frameworks to the “Output Files”:

$(BUILT_PRODUCTS_DIR)/$(FRAMEWORKS_FOLDER_PATH)/EAIntroView.framework
$(BUILT_PRODUCTS_DIR)/$(FRAMEWORKS_FOLDER_PATH)/EARestrictedScrollView.framework

CocoaPods

Add EAIntroView to your project's Podfile:
```
pod 'EAIntroView'
```
Run pod update or pod install in your project directory.

Setting Up Manually

Add EARestrictedScrollView header and implementation to your project (2 files total).
Add EAIntroPage and EAIntroView headers and implementations to your project (4 files total).
You can now use EAIntroView by adding the following import:
```
import EAIntroView
```
```
#import <EAIntroView/EAIntroView.h>
```

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.

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