Swift: Cropping a Screenshot without TabBar and NavigationBar

Question

I have a screenshot of the entire screen, screenshot, generated using the following:

let layer = UIApplication.sharedApplication().keyWindow!.l         


        

Answer 1

swift:

let contextImage: UIImage = <>!
let cropRect: CGRect = CGRectMake(x, y, width, height)
let imageRef: CGImageRef = CGImageCreateWithImageInRect(contextImage.CGImage, cropRect)
let image: UIImage = UIImage(CGImage: imageRef, scale: originalImage.scale, orientation: originalImage.imageOrientation)!

obj-c:

UIImage *image = <>;

CGRect croprect = CGRectMake(0, 0,
self.view.bounds.width,
self.view.bounds.height + self.navigationController!.navigationBar.frame.height));

// Draw new image in current graphics context
CGImageRef imageRef = CGImageCreateWithImageInRect([image CGImage], croprect);

// Create new cropped UIImage
UIImage *croppedImage = [UIImage imageWithCGImage:imageRef];
