Is it possible to capture the screen of an iPhone programatically?

Question

I am not sure that Apple allows this kind of stuff. I just want to make an application to take a screen capture whatever app is open on the iPhone not only the current application. Please suggest any solutions.

You can capture the things which are on a `UIView` but you can't capture which are on a `UIWindow`. For ex: If you have a `UIAlertView` presented, that won't be captured but other subviews of UIView will be — Rajan Maheshwari, Jul 28 '16 at 06:09

You cant capture Navigation Bar and all elements which are presented on UIWindow like AlertView, ActionSheet etc. — Rajan Maheshwari, Jul 28 '16 at 06:13

No, afraid not. Due to sandboxing, you only have access to your own app's window.

You can't capture screen of another applications or windows rather then your application. It's restricted by apple.

You can capture your application's screen by using UIGraphicsBeginImageContextWithOptions. for that you can refer this so post.

We can't capture any objects that are on UIWindow like `UIAlertView` or you can say `UIAlertController` – Rajan Maheshwari Jul 28 '16 at 06:14

You can find all information about background tasks here: https://developer.apple.com/library/ios/documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/BackgroundExecution/BackgroundExecution.html But I don't think, that Apple will allow you to take screenshots of other apps, as it could lead to security problems.

You can't capture other applications screen except your own application. Here is the code to take screen shot of the view

class Welcome: UIViewController {

       if ([[UIScreen mainScreen] respondsToSelector:@selector(scale)])
UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, NO, [UIScreen mainScreen].scale);
else
       UIGraphicsBeginImageContext(self.view.bounds.size);

       [self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
       UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
       UIGraphicsEndImageContext();

       UIImageWriteToSavedPhotosAlbum(image, self, nil, nil);

}
