为什么 MFMailComposeViewController 的“取消”或“发送”按钮不起作用？

我有一个问题...

我创建了一个 MFMailComposeViewController 并且它出现了。

但是，“发送”按钮和“取消”按钮都不起作用。

您必须在您的应用程序中添加此代码，

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

尝试一下这个代码，它可以正常使用发送和取消按钮。

You have to put on this code in ur application,

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

Try this one and it works send and cancel buttons properly.

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

[controller setSubject:@"Important Data"];

对于 html 文件邮件

NSString *path=[[NSBundle mainBundle]pathForResource:@"table" ofType:@"html"];
NSFileHandle *readHandle=[NSFileHandle fileHandleForReadingAtPath:path];
htmlString = [[NSString alloc] initWithData: [readHandle readDataToEndOfFile] encoding:NSUTF8StringEncoding];

NSString *emailBody=[NSString stringWithFormat:@"Product Name         %@ \n Company Name       %@  \n Last Updated Date   %@ \n desired data \n %@  ",lblProductName.text,lblCompanyName.text,lblUpdateDate.text,htmlString];

[controller setMessageBody:emailBody isHTML:YES];

[self presentModalViewController:controller animated:YES];

[controller release];

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

[controller setSubject:@"Important Data"];

for html file mail

NSString *path=[[NSBundle mainBundle]pathForResource:@"table" ofType:@"html"];
NSFileHandle *readHandle=[NSFileHandle fileHandleForReadingAtPath:path];
htmlString = [[NSString alloc] initWithData: [readHandle readDataToEndOfFile] encoding:NSUTF8StringEncoding];

NSString *emailBody=[NSString stringWithFormat:@"Product Name         %@ \n Company Name       %@  \n Last Updated Date   %@ \n desired data \n %@  ",lblProductName.text,lblCompanyName.text,lblUpdateDate.text,htmlString];

[controller setMessageBody:emailBody isHTML:YES];

[self presentModalViewController:controller animated:YES];

[controller release];

今天我发现Swift 3.0为这个问题带来了一个新的函数签名。在此之前，mailComposeController 从未被调用过，并且邮件（尽管确实发送了）只是停留在那里。当我改为下面时，它起作用了。

  public func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith: MFMailComposeResult, error: Error?) {

    self.dismiss(animated:true, completion: nil)


}

Today I found Swift 3.0 brings a new function signature to this question. Before this, mailComposeController was never even called, and the mail (although it did send) just stuck there. When I changed to below, it worked.

  public func mailComposeController(_ controller: MFMailComposeViewController, didFinishWith: MFMailComposeResult, error: Error?) {

    self.dismiss(animated:true, completion: nil)


}
