在应用程序中附加一个pdf文件 [英] Attach a pdf file in-app-mail

问题描述

我试图将我的pdf附加到应用内邮件。应用内邮件显示带有pdf的图标，但不发送。我不知道为什么...

I tried to attach my pdf to an in-app-mail. The in-app-mail displays an icon with the pdf but it doesn't send it. I don't know why...

这是代码：

- (void)openInEmail {

    if ([MFMailComposeViewController canSendMail]) {

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

        [viewController setSubject:@"Stundenplan 1A"];

        NSArray *sysPaths = NSSearchPathForDirectoriesInDomains( NSDocumentDirectory, NSUserDomainMask, YES );
        NSString *docDirectory = [sysPaths objectAtIndex:0];
        NSString *filePath = [NSString stringWithFormat:@"%@/Stundenplan_1A.pdf", docDirectory];

        NSMutableData *data=[NSMutableData dataWithContentsOfFile:filePath];

        [viewController addAttachmentData:data mimeType:@"text/pdf" fileName:@"Stundenplan_1A.pdf"];

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

任何想法？

推荐答案

更改这样的MIME类型。

Change the mime type like this.

NSURL *url = [NSURL URLWithString:pdfURL];
NSData *pdfData = [NSData dataWithContentsOfURL:url];
[mailComposeView addAttachmentData:pdfData mimeType:@"application/pdf" fileName:@"CheckList.pdf"];
