问题
How can you create a PHLivePhoto programmatically in Objective-C (such as from multiple UIImages, or some other means)? I can't find any solution in Apple's documentation. I know this must be possible in some way as there are multiple apps on the App Store that provide animated Live Photos to use as the Lock Screen on the iPhone 6S.
Any help would be greatly appreciated! Thanks
