Attach an captured image to an email on clicking a button - iphone

Question

I have captured image from iphone using the below UIImagePickerController delegate method.
- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
UIImage *image = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
self.myImageView.image = image;
// [self performSelector:#selector(emailButtonPressed:) withObject:image afterDelay:1.0];
[self dismissModalViewControllerAnimated:YES];
}
See above emailButtonPressed method it was called by self. I want to call this in a button action.
I wrote the code below for emailButtonPressed.
- (void)emailButtonPressed:(UIImage *)image
{
MFMailComposeViewController *mailview=[[MFMailComposeViewController alloc]init]; mailview.navigationBar.tintColor=[UIColor colorWithRed:55/255.0 green:190/255.0 blue:55/255.0 alpha:1];
mailview.mailComposeDelegate=self;
// NSMutableString *subject=[NSMutableString stringWithFormat:#"%#",#"Testing"];
[mailview setSubject:#"Picture from my iPhone!"];
// NSString *email_new=#"";
[mailview setMessageBody:#"Description" isHTML:NO];
NSData *imageData = UIImagePNGRepresentation(image);
[mailview addAttachmentData:imageData mimeType:#"image/png" fileName:#"ImageName"];
[self presentModalViewController:mailview animated:YES];
}
sorry for any mistakes in my code.

Answer 1

Modify your emailButtonPressed method as follows,
- (void)emailButtonPressed //removed the param
{
UIImage *image = self.myimageview.image; //or set some other param as image = self.image; whichever you set in picker delegate method
MFMailComposeViewController *mailview=[[MFMailComposeViewController alloc]init]; mailview.navigationBar.tintColor=[UIColor colorWithRed:55/255.0 green:190/255.0 blue:55/255.0 alpha:1];
mailview.mailComposeDelegate=self;
// NSMutableString *subject=[NSMutableString stringWithFormat:#"%#",#"Testing"];
[mailview setSubject:#"Picture from my iPhone!"];
// NSString *email_new=#"";
[mailview setMessageBody:#"Description" isHTML:NO];
NSData *imageData = UIImagePNGRepresentation(image);
[mailview addAttachmentData:imageData mimeType:#"image/png" fileName:#"ImageName"];
[self presentModalViewController:mailview animated:YES];
}
Keep this method as is,
- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
UIImage *image = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
self.myImageView.image = image; //instead of this, you can create an #property for image in .h file and assign to that also here.
[self dismissModalViewControllerAnimated:YES];
}
Assuming that you have declared your email button as,
UIButton *emailbutton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; //or any other way
Now add this method as your button target immediately after that line,
[emailbutton addTarget:self action:#selector(emailButtonPressed) forControlEvents:UIControlEventTouchUpInside];
Now on tap of emailbutton whatever image you have set in self.myimageview.image in UIImagePickerController delegate will be sent as an attachment.
