样式

设置背景图片或者背景movie，然后在它们之上生成数个ViewController，默认是顶部一张图片，下面是标题和详细介绍，最下面是按钮和page

导入

pod 'Onboard'

使用

• 导入头文件#import "OnboardingViewController.h"

图片为背景

蒙板控制器生成方法

• title是标题
  
• body是介绍
  
• image是顶部图片
  
• buttonText是按钮文本
  
• block是按钮点击事件

```objc
OnboardingContentViewController *firstPage = [OnboardingContentViewController contentWithTitle:@"What A Beautiful Photo" body:@"This city background image is so beautiful." image:[UIImage imageNamed:@"blue"] buttonText:@"Enable Location Services" action:^{
}];

OnboardingContentViewController *secondPage = [OnboardingContentViewController contentWithTitle:@"I'm so sorry" body:@"I can't get over the nice blurry background photo." image:[UIImage imageNamed:@"red"] buttonText:@"Connect With Facebook" action:^{
}];
secondPage.movesToNextViewController = YES;
secondPage.viewDidAppearBlock = ^{
};

OnboardingContentViewController *thirdPage = [OnboardingContentViewController contentWithTitle:@"Seriously Though" body:@"Kudos to the photographer." image:[UIImage imageNamed:@"yellow"] buttonText:@"Get Started" action:^{
}];
```

底部图片控制器

	OnboardingViewController *onboardingVC = [OnboardingViewController onboardWithBackgroundImage:[UIImage imageNamed:@"milky_way.jpg"] contents:@[firstPage, secondPage, thirdPage]];

底部video控制器

	NSBundle *bundle = [NSBundle mainBundle];	NSString *moviePath = [bundle pathForResource:@"yourVid" ofType:@"mp4"];	NSURL *movieURL = [NSURL fileURLWithPath:moviePath];	OnboardingViewController *onboardingVC = [OnboardingViewController onboardWithBackgroundVideoURL:movieURL contents:@[firstPage, secondPage, thirdPage]];

定制

• 默认的会给背景图片或者movie加一层黑色的蒙板，可以去掉它们：

	onboardingVC.shouldFadeTransitions = YES;

• 可以给图片加上模糊效果（相当漂亮）：

	onboardingVC.shouldBlurBackground = YES;

• 可以给蒙板上的文字加上淡出效果：

	onboardingVC.shouldFadeTransitions = YES;
