问题 Has anyone faced an issue where the MFMailcomposeviewcontroller send button is disabled/grayed out? The cancel button works perfectly fine. It seems like a new bug? 回答1: This could happen in case native Mail application is removed from iPhone (allowed starting from iOS 10). In this case system Setting missing "Mail" setting item and system probably cannot get configuration of default email account. At the same moment MFMailComposeViewController.canSendMail() return true , so I did not find

问题 Writing the part of the app that allows the user to generate a pdf and send it. Seems to be working fine. The sent PDF opens fine on the MAC, but on the iPhone it just keeps loading and never opens.
