Question

我已阅读其他主题并尝试了多个变量。

我有一个应用程序，可以将屏幕截图附加到应用内电子邮件中当我按下发送或取消按钮时，电子邮件不会被解雇。

不确定我是否有代理此行动。

代码：

.h

- (IBAction)openMail: (id)sender;

.m

//Open Mail
- (IBAction)openMail: (id)sender {
UIGraphicsBeginImageContext(self.view.bounds.size);
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
//UIImageWriteToSavedPhotosAlbum(viewImage, nil, nil, nil);

NSData * imageData = UIImageJPEGRepresentation(viewImage,2.0);

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

    /* Configure other settings */
    [mailComposer setSubject:@""];
    [mailComposer setToRecipients:[NSArray arrayWithObjects:@"", nil]];
    [mailComposer setToRecipients:[NSArray arrayWithObjects:@"%@", nil]];
    [mailComposer setSubject:@"4-4-2 Tactics/Line Up"];
    //[mailComposer setMessageBody:AddNotesTextField.text isHTML:NO];
    [mailComposer setModalTransitionStyle:UIModalTransitionStyleCrossDissolve];

    [self presentViewController:mailComposer animated:YES completion:nil];
}

- (void)mailComposeController:(MFMailComposeViewController*)controller   
didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error{
if (error) { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error" message:  
[NSString stringWithFormat:@"Error %@", [error description]] delegate:self 
cancelButtonTitle:@"Dismiss" otherButtonTitles:nil];
    [alert show];
}
[self dismissViewControllerAnimated:YES completion:NULL];

}

newMedia = YES;
}

Answer 1

弄清楚了。

这就是我需要的。

//打开邮件

- (IBAction)openMail: (id)sender {

UIGraphicsBeginImageContext(self.view.bounds.size);
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
//UIImageWriteToSavedPhotosAlbum(viewImage, nil, nil, nil);

NSData * imageData = UIImageJPEGRepresentation(viewImage,2.0);


MFMailComposeViewController *mailComposer = [[MFMailComposeViewController alloc] init];
[mailComposer setMailComposeDelegate:self];
if ([MFMailComposeViewController canSendMail]) {
    [mailComposer setToRecipients:[NSArray arrayWithObjects:@"%@", nil]];
    [mailComposer setSubject:@"4-4-2 Tactics/Line Up"];
    [mailComposer setMessageBody:AddNotesTextField.text isHTML:NO];
    [mailComposer addAttachmentData:imageData mimeType:@"image/png" fileName:@"attachment.jpng"];
    [mailComposer setModalTransitionStyle:UIModalTransitionStyleCrossDissolve];
    [self presentViewController:mailComposer animated:YES completion:nil];
}

newMedia = YES;


}

非常微妙的变化

Answer 2

也许你应该试试这个

[self dismissViewControllerAnimated:YES completion:nil];

在应用程序中，电子邮件将发送电子邮件，但不会在Xcode中解散
