我想在Swift 2.0和Xcode 7.0.1中使用MFMailComposeViewController()。我担心,这是一个重复的问题,但没有找到解决方案。
我的代码:
<%= fields_for :user do |user|
...
<% end %>
和
@IBAction func sendMail(sender: AnyObject) {
let picker = MFMailComposeViewController()
picker.mailComposeDelegate = self
picker.setSubject(subject.text!)
picker.setMessageBody(body.text, isHTML: true)
presentViewController(picker, animated: true, completion: nil)
}
引发错误 打印(&#34;邮件已取消&#34;)
当我在我的设备(iPad)上测试时,一切都很好。但是当我使用模拟器时,我得到了错误
func mailComposeController(controller: MFMailComposeViewController, didFinishWithResult result: MFMailComposeResult, error: NSError?) {
switch result.rawValue {
case MFMailComposeResultCancelled.rawValue:
print("Mail cancelled")
case MFMailComposeResultSaved.rawValue:
print("Mail saved")
case MFMailComposeResultSent.rawValue:
print("Mail sent")
case MFMailComposeResultFailed.rawValue:
print("Mail sent failure: \(error!.localizedDescription)")
default:
break
}
dismissViewControllerAnimated(true, completion: nil)
但是我想在模拟器中运行它,看看它在iPhone 6上的外观......
答案 0 :(得分:0)
您必须先检查设备是否可以使用MFMailComposeViewController.canSendMail()
发送邮件
@IBAction func sendMail(sender: AnyObject) {
guard MFMailComposeViewController.canSendMail()
else {
// TODO: Alert the user its device cannot send mail
print("Mail services are not available")
return
}
let picker = MFMailComposeViewController()
picker.mailComposeDelegate = self
picker.setSubject(subject.text!)
picker.setMessageBody(body.text, isHTML: true)
presentViewController(picker, animated: true, completion: nil)
}
