##How To Use It

Sample project have some examples of customization. Look in viewDidAppear, uncomment some lines to see variants.

###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, custom view in EAIntroPage, this way every other option is ignored.

Simple

EAIntroPage *page1 = [EAIntroPage page];
page1.title = @"Hello world";
page1.desc = @"Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.";

Custom

EAIntroPage *page3 = [EAIntroPage page];
page3.title = @"This is page 3";
page3.titleFont = [UIFont fontWithName:@"Georgia-BoldItalic" size:20];
page3.titlePositionY = 220;
page3.desc = @"Neque porro quisquam est, qui dolorem ipsum quia dolor sit amet, consectetur, adipisci velit.";
page3.descFont = [UIFont fontWithName:@"Georgia-Italic" size:18];
page3.descPositionY = 200;
page3.titleImage = [UIImage imageNamed:@"femalecodertocat"];
page3.imgPositionY = 100;

Custom view

UIView *viewForPage2 = [[UIView alloc] initWithFrame:self.view.bounds];
UILabel *labelForPage2 = [[UILabel alloc] initWithFrame:CGRectMake(0, 220, 300, 30)];
labelForPage2.text = @"Some custom view";
labelForPage2.font = [UIFont systemFontOfSize:32];
labelForPage2.textColor = [UIColor whiteColor];
labelForPage2.backgroundColor = [UIColor clearColor];
labelForPage2.transform = CGAffineTransformMakeRotation(M_PI_2*3);
[viewForPage2 addSubview:labelForPage2];
EAIntroPage *page2 = [EAIntroPage pageWithCustomView:viewForPage2];

###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.

Simple

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

Custom

EAIntroView *intro = [[EAIntroView alloc] initWithFrame:self.view.bounds andPages:@[page1,page2,page3]];
intro.backgroundColor = [UIColor colorWithRed:1.0f green:0.58f blue:0.21f alpha:1.0f]; //iOS7 orange    
intro.pageControlY = 100.0f;    
UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[btn setBackgroundImage:[UIImage imageNamed:@"skipButton"] forState:UIControlStateNormal];
[btn setFrame:CGRectMake((320-230)/2, [UIScreen mainScreen].bounds.size.height - 60, 230, 40)];
[btn setTitle:@"SKIP NOW" forState:UIControlStateNormal];
[btn setTitleColor:[UIColor blueColor] forState:UIControlStateNormal];
intro.skipButton = btn;

Don't forget to set the delegate to the calling class if you are using delegation for 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.

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 and pass it to EAIntroView property in setPages:.
