Turn a UIView into a UIImage

Question

How can I turn a UIView (with subviews as UIImageViews) into a UIImage programatically?

Is this a common practice?

Answer 1

For anyone looking for a Swift 4 answer on iOS 10+

let renderer = UIGraphicsImageRenderer(bounds: view.bounds)
let image = renderer.image { rendererContext in
    view.layer.render(in: rendererContext.cgContext)
}

Seems you want a "screenshot" of a particular view?

UIGraphicsBeginImageContext(view.bounds.size); 
CGContextRef ctx = UIGraphicsGetCurrentContext();
[view.layer renderInContext:ctx];
UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
