objective-c - 关闭 mailComposeController

Question

如果用户发送或取消，我试图在完成后从我的应用程序中关闭邮件。但出于某种原因，这永远不会被驳回。我几乎尝试了一切。我也记录了这个，所以我会看看它是否进入了 dissmiss 方法。问题就在那里，因为它从未进入 dismiss 方法。

我做错了什么？？？

- (IBAction)sendmail:(id)sender{
    UIGraphicsBeginImageContext(self.view.frame.size);
    [self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
    UIImage * image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    NSData * imageData = UIImageJPEGRepresentation(image, 1.0);

    if ( [MFMailComposeViewController canSendMail] ) {
        MFMailComposeViewController * mailComposer = [[MFMailComposeViewController alloc] init];
        mailComposer.delegate = self;
        [mailComposer addAttachmentData:imageData mimeType:@"image/jpeg" fileName:@"attachment.jpg"];

        [mailComposer setSubject:@"Hello from My App!"];

        NSString *emailBody = @"Sent from My App, Still not in AppStore!";
        [mailComposer setMessageBody:emailBody isHTML:YES];

        [self presentModalViewController:mailComposer animated:YES];
    }
}

-(void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error
{ 
    [self dismissModalViewControllerAnimated:YES];

    NSLog (@"mail finished"); // NEVER REACHES THIS POINT.
}

Answer 1

你可以替换这一行:

[self dismissModalViewControllerAnimated:YES];

使用以下行:

[controller dismissModalViewControllerAnimated:YES];
