My first question here:) Recently I update my Xcode to 8, and the resizableSnapshotView
method doesn\'t work properly on some simulators. The snapshotView works we
Works in:
Swift 3
import Foundation
import UIKit
extension UIView {
func snapshotView() -> UIView? {
guard let image = snapshotImage() else { return nil }
return UIImageView(image: image)
}
func snapshotImage() -> UIImage? {
UIGraphicsBeginImageContextWithOptions(bounds.size, isOpaque, contentScaleFactor)
defer { UIGraphicsEndImageContext() }
drawHierarchy(in: bounds, afterScreenUpdates: false)
return UIGraphicsGetImageFromCurrentImageContext()
}
}
Use the following UIView extension to create a snapshot using CoreGraphics.
I can confirm this works on iPhone 7 simulator.
public extension UIView {
public func snapshotImage() -> UIImage? {
UIGraphicsBeginImageContextWithOptions(bounds.size, isOpaque, 0)
drawHierarchy(in: bounds, afterScreenUpdates: false)
let snapshotImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return snapshotImage
}
public func snapshotView() -> UIView? {
if let snapshotImage = snapshotImage() {
return UIImageView(image: snapshotImage)
} else {
return nil
}
}
}
