cocoa-touch - Xcode：检查电子邮件是否已发送或取消

Question

我想login通过电子邮件注册，为此我必须检查用户是否点击了“发送”或“取消”。有没有可能检查这个？因为如果用户不发送它，我不希望他进入我的应用程序。问候

如果您使用默认值MFMailComposeViewController，请尝试检查“ (MFMailComposeResult)result”：

// Then implement the delegate method
- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error {
    [self dismissModalViewControllerAnimated:YES];
}




enum MFMailComposeResult {

   MFMailComposeResultCancelled,

   MFMailComposeResultSaved,

   MFMailComposeResultSent,

   MFMailComposeResultFailed

};
typedef enum MFMailComposeResult MFMailComposeResult;
