我正在尝试使用MFMailComposeViewController发送电子邮件.我可以发送附有图像的电子邮件,但是当我尝试附加mp3或mp4文件时,我收到以下消息:

DA |无法在/tmp/DAAccountsLoading.lock中打开锁定文件.无论如何我们都会加载帐户,但可能会发生不好的事情

(如果似乎在我开始填写"To"字段后出现,并且发送消息失败.

这是我的代码(HelperUtils类只是我创建的东西,我确定问题不存在):

NSData *myData = [NSData dataWithContentsOfFile:[HelperUtils getPathWithEnding:media.name]];
NSString *mimeTypeStr = [HelperUtils getMimeTypeOfFileWithPath:[HelperUtils getPathWithEnding:media.name]];
NSLog(mimeTypeStr);
NSLog([HelperUtils getPathWithEnding:media.name]);
[picker addAttachmentData:myData mimeType:mimeTypeStr fileName:media.name];

我想以编程方式从我的应用程序发送.doc文件作为电子邮件附件.

我使用以下代码在电子邮件正文中显示超链接.但它只显示邮件正文中的文本.当我点击它时.没有任何反应.

-(IBAction)emailToFriend:(id)sender
{
    NSLog(@"E-Mail...");
    MFMailComposeViewController *controller = [[MFMailComposeViewController alloc] init];
    controller.mailComposeDelegate = self;

    [controller setSubject:@"My Subject"];



    [controller setMessageBody:@"<a href=\"http://www.google.com\">http://www.google.com</a>" isHTML:YES]; 

    [self presentModalViewController:controller animated:YES];
    [controller release];

}

任何人都可以告诉我这里有什么问题吗？我检查了问题MFMailComposeViewController:我如何将可点击的URL链接嵌入到电子邮件正文中它没有帮助我

好的,这一直困扰着我一段时间......

我已检查过,所有其他问题/答案都与非ARC项目有关.

每当我提出MFMCvc并且我快速取消消息时,我就会在iPhone上收到Thread1:EXEC_BAD_ACCESS错误消息.可以在iPad上正常工作,或者我让它静坐(比如30秒或更长时间)

有什么建议吗？(除了放一个计时器而不是在计时器启动之前解雇？)

BTW我对MFMessageComposeViewController做了同样的事情,它在iPhone和iPad上运行良好.

这是我的代码来呈现它

if (([action isEqualToString:@"EMail"]) && contact.length>0)
{
    MFMailComposeViewController *mailViewController = [[MFMailComposeViewController alloc] init];
    if([MFMailComposeViewController canSendMail]) {
        [mailViewController setSubject:@""];
        [mailViewController setMessageBody:@"" isHTML:NO];
        [mailViewController setToRecipients:[NSArray arrayWithObject:contact]];
        [mailViewController setMailComposeDelegate:self];
        [self presentModalViewController:mailViewController animated:NO];
    }
}

这是我解雇它的地方

-(void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
    {
        switch (result)
        {
            case MFMailComposeResultCancelled:
            {
                UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Send EMail" message:@"EMail Has Been Cancelled"
                                                               delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];
                [alert show];
            }
                break;
            case MFMailComposeResultFailed:
            {
                NSLog(@"Error");
            }
                break;
            case MFMailComposeResultSent:
            {
                UIAlertView *alert = …

我使用以下内容来显示mailViewController

-(IBAction)sendMailbuttonTapped {

if([MFMailComposeViewController canSendMail]) {
    MFMailComposeViewController *mailCont = [[MFMailComposeViewController alloc] init];
    mailCont.mailComposeDelegate = self;

    [mailCont setSubject:@"yo!"];
    [mailCont setToRecipients:[NSArray arrayWithObject:@"surendherbtech@gmail.com"]];
    [mailCont setMessageBody:@"Don't ever want to give you up" isHTML:NO];

    [self presentModalViewController:mailCont animated:YES];
    [mailCont release];
}


}


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

它显示良好但我现在需要的是,我希望在他点击按钮时不用用户的知识发送邮件.它必须在没有用户点击发送选项的情

任何人都可以告诉我如何自动发送邮件提前谢谢

我在我的App Delegate中有这个代码:

[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"Nav Bar.png"] forBarMetrics:UIBarMetricsDefault];

这很好用,但我使用它MFMailComposeViewController,我希望它具有默认的NavigationBar外观.

我怎么做？

编辑:

我试过这段代码:

[[UINavigationBar appearanceWhenContainedIn: [MFMailComposeViewController class], [UIViewController class], nil] setBackgroundImage:[UIImage imageNamed:@"Textured Background.png"] forBarMetrics:UIBarMetricsDefault];

我也试过只有这个代码.没有什么变化.默认导航栏,包括邮件视图控制器.

我认为它可能与之相关appearanceWhenContainedIn:.有谁知道MFMailComposeViewController会包含什么？

我正在努力在我的应用程序中实现Peek和Pop,以及UIPreviewActions.我的PreviewView都设置好了,Peek和Pop都很棒,我的问题是添加UIPreviewActions.当然,您必须将UIPreviewAction方法放在预览控制器中,那么如何获取它然后关闭该视图,并在其父控制器中打开视图？

我在PreviewController中:

- (NSArray*)previewActionItems {

    // setup a list of preview actions
    UIPreviewAction *action1 = [UIPreviewAction actionWithTitle:@"Post to Facebook" style:UIPreviewActionStyleDefault handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) {


    }];

    UIPreviewAction *action2 = [UIPreviewAction actionWithTitle:@"Message" style:UIPreviewActionStyleDefault handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) {


    }];

    UIPreviewAction *action3 = [UIPreviewAction actionWithTitle:@"Email" style:UIPreviewActionStyleDefault handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) {
        [self displayComposerSheet];


    }];

    // add them to an arrary
    NSArray *actions = @[action1, action2, action3];

    // and return them …

我想使用MFMessageComposeViewController向多个收件人发送一条消息，我无法添加第二个等收件人

这是我的代码：

@IBAction func sendSms(sender: AnyObject) {

        if (MFMessageComposeViewController.canSendText())
        {
            let controller = MFMessageComposeViewController()
            controller.body = self.textView.text
            controller.recipients = [self.phoneField.text!]
            controller.messageComposeDelegate = self
            self.presentViewController(controller, animated: true, completion: nil)
        }
        else
        {
            print("Error")
        }
    }

extension MyViewController : MFMessageComposeViewControllerDelegate 
{
    func messageComposeViewController(_ controller: MFMessageComposeViewController, didFinishWith result: MessageComposeResult)     
    {
            controller.dismissViewControllerAnimated(true, completion: nil)}
    }
}

任何建议如何将其发送给多个收件人？

非常感谢 Paulw11 帮助我解决了这个问题。我在这里添加了完整的代码以便于重用：

班级：

import UIKit
import MessageUI

struct Feedback {
    let recipients: [String]
    let subject: String
    let body: String
    let footer: String
}

class FeedbackManager: NSObject, MFMailComposeViewControllerDelegate {

private var feedback: Feedback

private var completion: ((Result<MFMailComposeResult,Error>)->Void)?

override init() {
    fatalError("Use FeedbackManager(feedback:)")
}

init?(feedback: Feedback) {
    guard MFMailComposeViewController.canSendMail() else {
        return nil
    }
    
    self.feedback = feedback
}

func send(on viewController: UIViewController, completion:(@escaping(Result<MFMailComposeResult,Error>)->Void)) {
    
    let mailVC = MFMailComposeViewController()
    self.completion = completion
    
    mailVC.mailComposeDelegate = self
    mailVC.setToRecipients(feedback.recipients)
    mailVC.setSubject(feedback.subject)
    mailVC.setMessageBody("<p>\(feedback.body)<br><br><br><br><br>\(feedback.footer)</p>", isHTML: true)
    
    viewController.present(mailVC, …

自从我为新的iOS 5.0更新了XCode后,我的MailComposer函数中出现了警告.

 MFMailComposeViewController *pickerZap = [[MFMailComposeViewController alloc] init];
 pickerZap.mailComposeDelegate = self;
 // warning: Assigning to 'id<MFMailComposeViewControllerDelegate>' 
 // from incompatible type 'Infocontroller *'

MFMailComposeViewControllerDelegate发生了什么？我究竟做错了什么？
