ios - 如何使用 swift 使用 UIActivityViewController 仅通过电子邮件共享

Question

 let activityViewController = UIActivityViewController (activityItems: contentArray, applicationActivities:nil)
        if let popoverController = activityViewController.popoverPresentationController {
            popoverController.sourceView = sender

        }
        self.presentViewController(activityViewController, animated: true, completion: nil)

所以基本上我只想通过邮件分享内容，我不想显示消息选项。你能帮我解决这个问题吗？另外我想通过代码设置邮件的主题

Answer 1

只需添加 excludedActivityTypes 即可删除除电子邮件以外的所有其他事件

yourActivityViewController.excludedActivityTypes = [ UIActivityTypePostToFacebook, UIActivityTypePostToTwitter, UIActivityTypePostToWeibo, UIActivityTypeMessage, UIActivityTypePrint, UIActivityTypeCopyToPasteboard,UIActivityTypeAssignToContact,UIActivityTypeSaveToCameraRoll,UIActivityTypeAddToReadingList, UIActivityTypePostToFlickr, UIActivityTypePostToVimeo,UIActivityTypePostToTencentWeibo,UIActivityTypeAirDrop]

添加主题

 yourActivityViewController.setValue("Your email Subject" , forKey: "subject") ;

建议:-您还可以使用 MFMailComposeViewController 发送电子邮件

 var picker = MFMailComposeViewController()
    picker.mailComposeDelegate = self
    picker.setSubject(subject.text)
    picker.setMessageBody(body.text, isHTML: true)

    presentViewController(picker, animated: true, completion: nil)
