Question

I’ve created a form kind of app form, Where a user feeds the data and it dynamically processes it and displays the output there itself.

Now I want to write a code on Button say Send Mail Clicking on it should launch the default mail app (it would be better if it launches without closing my application) and should attach the current screen either in Png or pdf format of my form.

Answer 1

you can create a UIImage of the current screen by doing:

UIGraphicsBeginImageContext(self.view.bounds.size);
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

as far as composing the mail goes, look at MFMailComposeViewController.
