MFMailComposeViewController 不解雇

发布于 2024-12-08 19:55:20 字数 918 浏览 3 评论 0原文

我有在 didSelectRowAtIndexPath 中调用的以下代码。问题是，当我点击取消按钮时，它提示保存草稿或放弃。但是当我单击其中任何一个时，视图都不会消失。我在 iOS 5 之前的应用程序中使用了相同的代码，并且效果很好。有什么想法吗？我在界面中有 MFMailComposeViewController 委托协议。

    if (indexPath.row == 0)
    {
        if([MFMailComposeViewController canSendMail])
        {

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

            [picker setSubject:@"Support"];

            NSArray *toRecipients = [NSArray arrayWithObject:@"[email protected]"]; 

            [picker setToRecipients:toRecipients];

            NSString *emailBody = text;
            [picker setMessageBody:emailBody isHTML:NO];

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

I have the following code that gets called in didSelectRowAtIndexPath. The issue is, when I click the cancel button, it prompts for save draft or discard. But when I click either, the view does not dismiss. I've used the same code in a pre iOS 5 app and it dismissed fine. Any ideas? I have the MFMailComposeViewController delegate protocol in the interface.

    if (indexPath.row == 0)
    {
        if([MFMailComposeViewController canSendMail])
        {

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

            [picker setSubject:@"Support"];

            NSArray *toRecipients = [NSArray arrayWithObject:@"[email protected]"]; 

            [picker setToRecipients:toRecipients];

            NSString *emailBody = text;
            [picker setMessageBody:emailBody isHTML:NO];

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

使用：

dismissViewControllerAnimated:completion:

从 IOS 6.0 开始已弃用：

将此方法添加到您的类中：

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

玩得开心

Use:

dismissViewControllerAnimated:completion:

DEPRECATED FROM IOS 6.0:

Add this method to your class:

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

Have fun

可能存在几个问题：

未在 .h 中添加协议实现

@interface yourClass : UIViewController ;

不在.m中添加相关函数：

-(void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)结果错误:(NSError*)error {
     [自我解雇ModalViewControllerAnimated：是]；
}

我的错误是没有设置正确的委托，但我修复了它:)，现在它对我有用：
```
 picker.mailComposeDelegate = self;
```

There could be several problems:

Not adding protocol implemantation in the .h

@interface yourClass : UIViewController <MFMailComposeViewControllerDelegate>

Not adding the relevant function in .m:

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

My error was not setting the correct delegate, but I fixed it :) and now it works for me:
```
 picker.mailComposeDelegate = self;
```

“dismissModalViewControllerAnimated:”在 iOS 6.0 中已弃用

iOS 7 使用：

“dismissViewControllerAnimated:completion:”

我在这里更详细地描述了该问题以及解决该问题的方法：https://stackoverflow。 com/a/13576408/691660

我不确定旅达是否抓住了问题的核心。无论您是否指定委托都没有区别，这在模态+模态 MFMailComposeViewController 实例的情况下不起作用。

Swift 实现：

确保您的 MFMailComposeViewController 协议和委托在每次执行其函数时都被调用。

这解决了 MFMailComposeViewController 不被解雇的问题。

     let subj = "Test"
     let messageBody = "Test"
     let toRecipents = ["[email protected]"]
     let mc: MFMailComposeViewController = MFMailComposeViewController()
     mc.mailComposeDelegate = self
     mc.setSubject(subj)
     mc.setMessageBody(messageBody, isHTML: true)
     mc.setToRecipients(toRecipents)
     self.present(mc, animated: true, completion: nil)

Swift Implementation:

Make sure your MFMailComposeViewController protocol and delegate is being called every time its function being executed.

This solves the issue of MFMailComposeViewController not being dismissed.

     let subj = "Test"
     let messageBody = "Test"
     let toRecipents = ["[email protected]"]
     let mc: MFMailComposeViewController = MFMailComposeViewController()
     mc.mailComposeDelegate = self
     mc.setSubject(subj)
     mc.setMessageBody(messageBody, isHTML: true)
     mc.setToRecipients(toRecipents)
     self.present(mc, animated: true, completion: nil)
