Trying to attach image to mail in my app - ios

Question

I'm using the UIimagepicker to choose an image that should be attached to a mail in my ios app. I'm getting this error:
Warning: Attempt to present < MFMailComposeViewController: 0xc142ab0 > on < ViewControllerMail: 0xb642520 > while a presentation is in progress!
I'm new to this so.. i gues i'm dismissing the views wrong? I don't even know if the code works to attach the choosen image.
- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
NSString *mediaType = [info objectForKey: UIImagePickerControllerMediaType];
UIImage *originalImage, *editedImage, *imageToUse;
// Handle a still image picked from a photo album
if (CFStringCompare ((CFStringRef) mediaType, kUTTypeImage, 0)
== kCFCompareEqualTo) {
editedImage = (UIImage *) [info objectForKey:
UIImagePickerControllerEditedImage];
originalImage = (UIImage *) [info objectForKey:
UIImagePickerControllerOriginalImage];
if (editedImage) {
imageToUse = editedImage;
} else {
imageToUse = originalImage;
[self dismissViewControllerAnimated:YES completion:NULL];
}
MFMailComposeViewController * mailComposer = [[MFMailComposeViewController alloc]init];
mailComposer.mailComposeDelegate = self;
// make sure you can make NSData from the object
[mailComposer addAttachmentData:UIImageJPEGRepresentation(imageToUse, 1.0) mimeType:#"image/jpg" fileName:#"what ever you want to call the file"];
[self presentViewController:mailComposer animated:YES completion:nil];
}
}
Thank you!

The problem is that your are presenting the mail composer while the image picker is being dismissed. Make use of the completion parameter:
[self dismissViewControllerAnimated:YES completion:^{
MFMailComposeViewController * mailComposer = [[MFMailComposeViewController alloc]init];
mailComposer.mailComposeDelegate = self;
// make sure you can make NSData from the object
[mailComposer addAttachmentData:UIImageJPEGRepresentation(imageToUse, 1.0) mimeType:#"image/jpg" fileName:#"what ever you want to call the file"];
[self presentViewController:mailComposer animated:YES completion:nil];
}];
