Add [self screenshot]; as email attachment? - ios

Question

I would like to add [self screenshot]; to my mail function as attachment. How can I do this without saving the image to the photo library? Here´s my code in ViewController.m:
Screenshot Function:
- (UIImage *)screenshot
{
UIImage *backgroundImage = [UIImage imageNamed:#"iphoneframe.png"];
UIGraphicsBeginImageContext(backgroundImage.size);
[backgroundImage drawInRect:CGRectMake(0, 0, backgroundImage.size.width, backgroundImage.size.height)];
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
[screenshot drawInRect:CGRectMake(backgroundImage.size.width - screenshot.size.width, backgroundImage.size.height - screenshot.size.height, screenshot.size.width, screenshot.size.height)];
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return image;
}
E-Mail Function:
- (void)sendMail
{
if ([MFMailComposeViewController canSendMail]){
MFMailComposeViewController *mailer = [[MFMailComposeViewController alloc] init];
mailer.mailComposeDelegate = self;
[mailer setSubject:#"Mein Punktestand bei KlickMich"];
//Attachement Object
UIImage *myImage = [UIImage imageNamed:#"image.jpg"];
NSData *imageData = UIImagePNGRepresentation(myImage);
[mailer addAttachmentData:imageData mimeType:#"image/jpg" fileName:#"image.jpg"];
NSString *messageBody = [NSString stringWithFormat:#"Hey, habe gerade ganze %i Punkte innerhalb von nur 15 Sekunden in der KlickMich App erreicht. Kannst du es besser?<br /><br />-> <a href='http://appstore.com/KlickMich'>appstore.com/KlickMich</a>",count];
[mailer setMessageBody:messageBody isHTML:YES];
[self presentViewController:mailer animated:YES completion:NULL];
}
[…]
Yours faithfully

When you take a screenshot that time you have to save your image in DocumentDirectory like this :
NSArray *path=NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *imagePath=[path objectAtIndex:0];
NSFileManager *fileManager = [NSFileManager defaultManager] ;
BOOL isDir ;
imagePath =[imagePath stringByAppendingPathComponent:#"MyImage"];
if(YES == [fileManager fileExistsAtPath:imagePath isDirectory:&isDir])
{
}
else
{
[fileManager createDirectoryAtPath:imagePath withIntermediateDirectories:NO attributes:nil error:nil];
}
imagePath =[imagePath stringByAppendingPathComponent:#"Image.jpg"];
NSData *tempImageData=[NSData dataWithData:UIImagePNGRepresentation(viewImage)];
[tempImageData writeToFile:imagePath atomically:YES];
When you want to share that image you have to retrieve that image from DocumentDirectory & share it.
NSFileManager *fileManager = [NSFileManager defaultManager] ;
NSArray *path=NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *imagePath=[path objectAtIndex:0];
imagePath =[imagePath stringByAppendingPathComponent:#"MyImage"];
NSArray *temp=[fileManager contentsOfDirectoryAtPath:imagePath error:nil];
NSString *tempImgPath = [imagePath stringByAppendingPathComponent:[temp objectAtIndex:0]];
NSData *imgData = [NSData dataWithContentsOfFile:tempImgPath];
MFMailComposeViewController *mailer = [[MFMailComposeViewController alloc] init];
mailer.mailComposeDelegate = self;
[mailer setSubject:#"Mein Punktestand bei KlickMich"];
[mailer addAttachmentData:imgData mimeType:#"image/jpg" fileName:#"image.jpg"];
NSString *messageBody = [NSString stringWithFormat:#"Hey, habe gerade ganze %i Punkte innerhalb von nur 15 Sekunden in der KlickMich App erreicht. Kannst du es besser?<br /><br />-> <a href='http://appstore.com/KlickMich'>appstore.com/KlickMich</a>",count];
[mailer setMessageBody:messageBody isHTML:YES];
[self presentViewController:mailer animated:YES completion:NULL];
