iOS share extension dismiss keyboard
问题 I'm implementing a share extension for my app, so far everything is going good except I can't seem to dismiss the keyboard that automatically opens using the default layout/storyboard. I'm keeping the default design/layout (SLComposeServiceViewController) which includes the preview image and UITextview, the UITextview automatically gets in focus which opens the keyboard. Normally this is fine, but if you're not logged in my app I display an UIAlertController saying you need to login to share.
