I have a UIButton whose target performs some UIGraphicsBeginImageContextWithOptions
drawHierarchy
steps to create UIImage
from a few views.
let toPrint = cell.contentView UIGraphicsBeginImageContextWithOptions(toPrint.bounds.size, true, 0) toPrint.drawHierarchy(in: toPrint.bounds, afterScreenUpdates: true) if let image = UIGraphicsGetImageFromCurrentImageContext() { images.append(image) } UIGraphicsEndImageContext()
This causes the UIButton's on/off state change animation to stutter.
In iOS when once taps a UIButton, the knob animates from one position to another (off/on -> left to right knob animation). This iOS animation stutters when I perform my drawHierarchy
code.
Is there a way to fix this WITHOUT adding a delay?
