I want to convert a UIView to an image and save it in my app. Can someone please tell me how to take screenshot of a view or convert it to an image and what is the best way to save it in an app (Not camera roll)? Here is the code for the view:
var overView = UIView(frame: CGRectMake(0, 0, self.view.frame.width/1.3, self.view.frame.height/1.3))
overView.center = CGPointMake(CGRectGetMidX(self.view.bounds),
CGRectGetMidY(self.view.bounds)-self.view.frame.height/16);
overView.backgroundColor = UIColor.whiteColor()
self.view.addSubview(overView)
self.view.bringSubviewToFront(overView)
An extension on
UIView
should do the trick.Apple discourages using
UIGraphicsBeginImageContext
starting iOS 10 with the introduction of the P3 color gamut.UIGraphicsBeginImageContext
is sRGB and 32-bit only. They introduced the newUIGraphicsImageRenderer
API that is fully color managed, block-based, has subclasses for PDFs and images, and automatically manages the context lifetime. Check out WWDC16 session 205 for more details (image rendering begins around the 11:50 mark)To be sure that it works on every device, use
#available
with a fallback to earlier versions of iOS:
