How to attach screenshot to mailcomposer in iOS - iphone

Question

Hi i'm using the below code to attach screenshot to mailcomposer, i'm not having a device to check so will this work on actual device?
-(void)launchMailAppOnDevice
{
/*Take a SnapShot of current screen*/
UIGraphicsBeginImageContext(self.view.frame.size);
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage * image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
NSData * imageData = UIImageJPEGRepresentation(image, 1.0);
NSString *recipients = #"mailto:xyz#abc.com?cc=#\"\"&subject=blah!!blah!!";
NSString *body = #"&body=blah!!blah!!";
NSString *email = [NSString stringWithFormat:#"%#%#%#", recipients, body, imageData];
email = [email stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:email]];
}

Answer 1

The last 5 lines are wrong. You most likely want to use the MFMailComposeViewController class:
MFMailComposeViewController *mcv = [[MFMailComposeViewController alloc] init];
[mcv setSubject:#"blah!!blah!!"];
[mcv setToRecipients:[NSArray arrayWithObject:#"xyz#abc.com"]];
[mcv setMessageBody:#"Blah!! 'tis the body!" isHTML:NO];
[mcv addAttachmentData:imageData mimeType:#"image/jpeg" fileName:#"Screenshot.jpg"];
[someViewController presentModalViewController:mcv animated:YES];
[mcv release];
P. s.: don't forget to add the MessageUI framework to your project and also #import <MessageUI/MessageUI.h>.
P. p. s.: while it's important to test on an actual device, it's even more important to read some guides and documentation before writing the actual code.

Answer 2

You'll want to add:
NSData *imageData = UIImagePNGRepresentation(image);
[picker addAttachmentData:imageData mimeType:#"image/png" fileName:#"fileName"];
if you plan on using a MFMailComposeViewController, which you should use instead of mailto:, but I can't stress enough how important it is to always test your applications on a real device.
