Delete images in camera roll from code iOS

问题 Is there a way to delete images (and videos) in camera roll in the photos app that my app didn't create. I know you can't delete things from Asset Library that your app didn't create. But this app isn't on app store. It's on a kiosk type environment. So I can use private APIs. So is there a way to do this using private APIs that apple would not approve for the app store, but would work for my situation. Thanks. 回答1: Yep, you can do this in iOS 8 using Photos framework. For example if you have

Getting Slow Motion meta data from captured video in iOS

问题 We have a video app that is importing video from the user's camera roll. Our problem is importing slo-mo video taken with the native Camera app. We can recognise that there is a higher than normal frame rate (e.g. 120 or 240 fps). What we can't find is the meta information that specifies when the video drops into slow motion and when it speeds up again. Does anyone know where this information is kept, and/or how to get at it? Is it in the file itself, or stored in a separate meta file

ios 8, how to get all photos using ALAssetLibrary to replace the missing camera roll album

问题 I have an app that has a custom Image Picker that uses the ALAssetLibrary to create an Album picker and image picker. We've implemented a custom picker in order for our customers to select multiple images. This image picker works great under iOS 7 and shows the "Camera Roll" album with ALL the user's photos. However, when running the same app under iOS 8, it seems that Apple has removed the "Camera Roll" album from the Albums view and only shows "Recent Photos". From what I can see, the only
