Question

I am working on an app where I need to save a part of iphone’s screen shot as JPEG and then send this through email. The part of screen has some text labels, fields etc. Any ideas please on how can I save part of screen as JPEG (I am a newbie therefore any help/sample code is highly appreciated)

Answer 1

The following code will save the contents of a view to the user’s photo library. You should be able to modify it to be able to email the file instead.

  CGRect myRect = [myView bounds];
  UIGraphicsBeginImageContext(myRect.size);

  CGContextRef ctx = UIGraphicsGetCurrentContext();
  [[UIColor blackColor] set];
  CGContextFillRect(ctx, myRect);

  [myView.layer renderInContext:ctx];

  UIImage *image1 = UIGraphicsGetImageFromCurrentImageContext();

  // Replace the following line with code that emails the image
  UIImageWriteToSavedPhotosAlbum(image1, nil, nil, nil);
  UIGraphicsEndImageContext();
