我正在尝试实现发送邮件代码,但是出现以下错误:
Attempting to load the view of a view controller while it is deallocating is not allowed and may result in undefined behavior
这是我的代码段:
if MFMailComposeViewController.canSendMail() {
let mail = MFMailComposeViewController()
mail.mailComposeDelegate = self
mail.setToRecipients(["@gmail.com"])
presentViewController(mail, animated: true, completion: nil)
} else {
// show failure alert
}
最佳答案
如果您忘记将按钮删除到按钮的另一功能,则可能会发生收到的错误。
关于ios - 不允许在取消分配时尝试加载 View Controller 的 View ,这可能会导致未定义的行为,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/33176169/
