iOS Lifecycle: Handling willEnterForeground in AppDelegate and SceneDelegate

by

Hope you guys already know that we need to migrate to scene-based life cycle in near future.

Below lines are written in this reference document provided by Apple.

In iOS 18.4, iPadOS 18.4, Mac Catalyst 18.4, tvOS 18.4, visionOS 2.4 and later, UIKit logs the this message for apps that haven’t adopted the scene-based life-cycle.

This process does not adopt UIScene lifecycle. This will become an assert in a future version.

Soon, all UIKit based apps will be required to adopt the scene-based life-cycle, after which your app won’t launch if you don’t. While supporting multiple scenes is encouraged, only adoption of scene life-cycle is required.

Here I am discussing about the methods applicationWillEnterForeground and sceneWillEnterForeground actually work same or not? As there are key differences let’s discuss in detail.

How to prevent screenshot for UIView in iOS?

by

iOS – Apple provides screenshot detection notification but not providing direct solution for prevention.

Here I found solution for preventing screenshot taking from the UIView. It’s a simple extension of the UIView that allows to hide it from screen-capturing and also from screen recording. The solution uses ability of UITextField to hide a password from capturing.

extension UIView {
func preventScreenshot() {
DispatchQueue.main.async {
let field = UITextField()
field.isSecureTextEntry = true
self.addSubview(field)
field.centerYAnchor.constraint(equalTo: self.centerYAnchor).isActive = true
field.centerXAnchor.constraint(equalTo: self.centerXAnchor).isActive = true
self.layer.superlayer?.addSublayer(field.layer)
field.layer.sublayers?.first?.addSublayer(self.layer)
}
}
}

Usage:

viewSecure.preventScreenshot()

So, when you take screenshot the logic of text field secure entry (password text field) will not allow to take screenshot of that part.

ScrollView Screenshot Prevention

Update: Here is recursive function for preventing screenshot.

extension UIView {
func preventScrollViewScreenshotRecursive() {
guard superview != nil else {
for subview in subviews {
subview.preventScrollViewScreenshotRecursive()
}
return
}
let guardTextField = UITextField()
guardTextField.backgroundColor = .red
guardTextField.translatesAutoresizingMaskIntoConstraints = false
guardTextField.tag = Int.max
guardTextField.isSecureTextEntry = true
addSubview(guardTextField)
guardTextField.isUserInteractionEnabled = false
sendSubviewToBack(guardTextField)
layer.superlayer?.addSublayer(guardTextField.layer)
guardTextField.layer.sublayers?.first?.addSublayer(layer)
guardTextField.centerYAnchor.constraint(
equalTo: self.centerYAnchor
).isActive = true
guardTextField.centerXAnchor.constraint(
equalTo: self.centerXAnchor
).isActive = true
}
}
