如果您不打算通过编写自己的应用程序来做到这一点.没办法啊！！！
If you are not gonna do it by writing your own application. There's no way you can do that!!!
首先，您描述的频繁拍照需要私有api.这将使您的应用被 App Store 拒绝.如果没问题，请阅读以下说明.
First, taking photos frequently as you described needs private apis. That will make your app rejected from App Store. If that's okay, read the instructions below.
转储名为PhotoLibrary"的私有库的标题.
Dump headers of a Private Library called 'PhotoLibrary'.
在 XCode 中设置您的项目.
Setup your project in XCode.
添加 [[PLCameraController sharedInstance] previewView] 到你的 UIWindow，在 applicationDidFinishLaunching:.
Add [[PLCameraController sharedInstance] previewView] to your UIWindow, in applicationDidFinishLaunching:.
创建一个 NSTimer，每 (30/20) 秒重复一次.
Create a NSTimer, repeats every (30/20) secs.
在定时器的回调中，运行
In the timer's callback, run
UIImage *image = [[PLCameraController sharedInstance] _createPreviewImage];
UIImage *image = [[PLCameraController sharedInstance] _createPreviewImage];
然后你会每 1.5 秒得到一个 UIImage.做任何你需要做的事情.您可能需要通过调用 UIImageWriteToAlbum() 将它们保存到相册.
Then you will get a UIImage every 1.5 second. Do whatever you need to do. You might need to save them to Photo Album by calling UIImageWriteToAlbum().
注意:这只会拍摄低分辨率的照片.不可能每 1.5 秒拍一张全分辨率照片.
Notice: This will only take photos of a low resolution. It's impossible to take full resolution photo per 1.5 second.
