Emailing photo taken with ImagePickerController? - iphone

Question

In my app I want to:
a.) Present camera to user to take picture
b.) Create email and attach picture taken
I figured out how to take the picture. But, I don't know how to attach it to the email. In the examples I've seen the filename is known. This is one example.
picker.mailComposeDelegate = self;
[picker setSubject:#"I have a pencil for you"];
UIImage *roboPic = [UIImage imageNamed:#"RobotWithPencil.jpg"];
NSData *imageData = UIImageJPEGRepresentation(roboPic, 1);
[picker addAttachmentData:imageData mimeType:#"image/jpg" fileName:#"RobotWithPencil.jpg"];
NSString *emailBody = #"This is a cool image of a robot I found. Check it out!";
[picker setMessageBody:emailBody isHTML:YES];
[self presentModalViewController:picker animated:YES];
I am getting the image from the callback method and it does get stored in the camera roll.
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
// Access the uncropped image from info dictionary
UIImage *image = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
[picker dismissModalViewControllerAnimated:TRUE];
[picker release];
}
But from there, I'm not sure how to attach the image to the email? Mainly because I don't know what the filename is when a photo is added to the camera roll when the UIImagePickerController camera source is used to obtain it?
So, I guess I need to either:
a.) Find a way to get the name of the image file once it is saved OR
b.) Another way to attach UIImage data as an email attachment.
Any help appreciated.

Answer 1

maybe I don't understand what you are trying to do UI wise, but why would this not work from your code provide:
EDIT: (changed code to use a delegate)
- (void)imagePickerController:(UIImagePickerController *)imagepicker didFinishPickingMediaWithInfo:(NSDictionary *)info {
// Access the uncropped image from info dictionary
UIImage *image = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
if([delegate respondsToSelector:#selector(didSelectImage:)])
[delegate didSelectImage:image];
}
this goes in your header file (usually above your class declaration):
#protocol PostHelperDelegate <NSObject>
#optional
- (void)DimissModal;
//image data for image selected
- (void)DidSelectImage:(UIImage*)image;
#end
also you need to create this property in your class
#property(nonatomic,assign)id<PostHelperDelegate>* delegate; //don't forgot to synthizie
then in the class implementing the delegate you will assign the delegate your class:
Poster = [[delegateclass alloc] init];
Poster.delegate = self;
then just add the delegate function:
- (void)DidSelectImage:(UIImage*)image
{
//handle image here
}
I simplify this quite a bit, let me know if you have any trouble getting it working

BEFORE UPDATE:
personally I would use a delegate to notify that the image has been picked and than launch the mail picker, but that is another thing. As far as the UIImage, I don't know a way or have never found a way to name/or get a name from the UIImagePicker as I do not believe they are named anything meaningful. Any questions on the delegate or further explanation let me know.

use bellow code
-(void)yourmethodname_clicked{
UIImagePickerController * picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentModalViewController:picker animated:YES];
}
else{
UIAlertView *altnot=[[UIAlertView alloc]initWithTitle:#"Camera Not Available" message:#"Camera Not Available" delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil, nil];
[altnot show];
[altnot release];
}
}
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[picker dismissModalViewControllerAnimated:YES];
MFMailComposeViewController *mailpicker = [[MFMailComposeViewController alloc] init];
[mailpicker.navigationBar setTintColor:[UIColor blackColor]];
mailpicker.mailComposeDelegate = self;
[mailpicker setSubject:#"set your subject"];
NSArray *toRecipients = [NSArray arrayWithObjects: nil];
[mailpicker setToRecipients:toRecipients];
UIImage *picture = [info objectForKey:#"UIImagePickerControllerOriginalImage"]];;
NSData *imageData = UIImagePNGRepresentation(picture);
[mailpicker addAttachmentData:imageData mimeType:#"image/png" fileName:#"set your file name"];
NSString *emailBody = #"set your body string";
[mailpicker setMessageBody:emailBody isHTML:YES];
[mailpicker setSubject:#"set your subject"];
mailpicker.title = #"Email";
[self presentModalViewController:mailpicker animated:YES];
[mailpicker release];
}
may this help you
