A Unity plugin to open native sharing dialogs on iOS and Android, primarily for sharing screenshots.
To use, copy the iOSNativeShare.h and iOSNativeShare.m files to Assets/Plugins/iOS and NativeShare.cs to Assets/Plugins, then call the Share method in NativeShare.cs. See NativeShare.cs for details. For Android, you'll need to have Write Access set to External(SDCard) under Android Build Settings/Other Settings.
Unity screenshots are run asynchronously and as such you will need to check that the file has been written, or put a delay between capturing the screenshot and sharing it using a coroutine. Otherwise you will likely end up trying to access a file that does not yet exist or will access a previous version of the screenshot.
Also, note that some apps cannot reliably accept a link, image, and text at once (at least Facebook and Whatsapp). If you pass both a link and an image to Facebook, the link 'takes over' and the image will not be posted. See this comment for more info: NicholasSheehan#19 (comment). Thank you ryhok for letting me know about this!
