Take Screenshot of Textfield in swift?

Question

Am making an iOS application which captures screenshot of a textview filled with some image. The problem is that the screen shot captures the entire screen. How do I take screen shot of UITextView using Swift?

Answer 1

You can save any view as image by using drawViewHierarchyInRect method

UIGraphicsBeginImageContextWithOptions(self.textView.bounds.size, false, 0);
self.textText.drawViewHierarchyInRect(CGRectMake(0, 0, self.textView.frame.size.width, self.textView.frame.size.height),afterScreenUpdates:true)
var screenShot:UIImage = UIGraphicsGetImageFromCurrentImageContext();

Answer 2

The following worked for me

UIGraphicsBeginImageContextWithOptions(self.textField.bounds.size, false, 0);
self.textField.drawViewHierarchyInRect(self.textField.bounds, afterScreenUpdates: true)
let copied = UIGraphicsGetImageFromCurrentImageContext();
imageView.image = copied
UIGraphicsEndImageContext();

All answers are good but missing is scale which is necessary in context .

Use UIView's drawViewHierarchyInRect mehtod to capture screen.

//Use screen scale for better images
let screenScale = UIScreen.mainScreen().scale;
//create context 
UIGraphicsBeginImageContextWithOptions(yourView.bounds.size, false, screenScale);
//use view for drawing
yourView.drawViewHierarchyInRect(yourView.bounds, afterScreenUpdates: true)
//get captured image
let capturedImage = UIGraphicsGetImageFromCurrentImageContext();
//last dump context
UIGraphicsEndImageContext();

Another sloution : use UIView's layer's renderInContext

//Use screen scale for better images
let screenScale = UIScreen.mainScreen().scale;
//create context 
UIGraphicsBeginImageContextWithOptions(yourView.bounds.size, false, screenScale);
//use view for drawing
yourView.layer.renderInContext(UIGraphicsGetCurrentContext())
//get captured image
let capturedImage = UIGraphicsGetImageFromCurrentImageContext();
//last dump context
UIGraphicsEndImageContext();
