Question

在buttonpress回调中：

 MFMailComposeViewController *mailViewController = [[MFMailComposeViewController alloc] init];
    mailViewController.mailComposeDelegate = self;

    [self presentModalViewController:mailViewController animated:YES];

代表实施：

- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error {
NSLog (@" Inside  MAIL COMPOSER CONTROLLER DELIGATE ");


// Remove the mail view
[self dismissModalViewControllerAnimated:YES];
}

当我按下MailComposerView中的取消按钮时，不会调用删除。我做错了什么？

Answer 1

将viewController设置为MFMailComposeViewControllerDelegate：

@interface CurrentViewController : UIViewController <MFMailComposeViewControllerDelegate>

在实例化后立即设置mailComposer委托：

MFMailComposeViewController * mailComposer = [[MFMailComposeViewController alloc]init];
mailComposer.mailComposeDelegate = self;

Answer 2

你真的让你的班级成为MFMailComposeViewControllerDelegate吗？

@interface MyViewController : UIViewController <MFMailComposeViewControllerDelegate>

没有为MFMailComposeViewController调用didFinishWithResult
