Screen Recording App Using Swift
The app we will be making today is extremely simple to write and use. There is a green button which is used to start screen recording. Once tapped, the button will turn red and the status label at the top of the screen will indicate that it is currently recording. The app also features a segmented view with various color names in it. Tapping a color will change the background of the square in the middle of the screen to that color. This is here so you can record something changing on the screen. There is also a microphone toggle so you can choose if you want to record with the microphone or not.
Write coding in ViewController.swift :-
import UIKit
import ReplayKit
class ViewController: UIViewController, RPPreviewViewControllerDelegate {
@IBOutlet var statusLabel: UILabel!
@IBOutlet var colorPicker: UISegmentedControl!
@IBOutlet var colorDisplay: UIView!
@IBOutlet var recordButton: UIButton!
@IBOutlet var micToggle: UISwitch!
let recorder = RPScreenRecorder.shared()
private var isRecording = false
override func viewDidLoad() {
super.viewDidLoad()
recordButton.layer.cornerRadius = 32.5
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
func viewReset() {
micToggle.isEnabled = true
statusLabel.text = "Ready to Record"
statusLabel.textColor = UIColor.black
recordButton.backgroundColor = UIColor.green
}
@IBAction func colors(sender: UISegmentedControl) {
switch sender.selectedSegmentIndex {
case 0:
colorDisplay.backgroundColor = UIColor.red
case 1:
colorDisplay.backgroundColor = UIColor.blue
case 2:
colorDisplay.backgroundColor = UIColor.orange
case 3:
colorDisplay.backgroundColor = UIColor.green
default:
colorDisplay.backgroundColor = UIColor.red
}
}
@IBAction func recordButtonTapped() {
if !isRecording {
startRecording()
} else {
stopRecording()
}
}
func startRecording() {
guard recorder.isAvailable else {
print("Recording is not available at this time.")
return
}
if micToggle.isOn {
recorder.isMicrophoneEnabled = true
} else {
recorder.isMicrophoneEnabled = false
}
recorder.startRecording{ [unowned self] (error) in
guard error == nil else {
print("There was an error starting the recording.")
return
}
print("Started Recording Successfully")
self.micToggle.isEnabled = false
self.recordButton.backgroundColor = UIColor.red
self.statusLabel.text = "Recording..."
self.statusLabel.textColor = UIColor.red
self.isRecording = true
}
}
func stopRecording() {
recorder.stopRecording { [unowned self] (preview, error) in
print("Stopped recording")
guard preview != nil else {
print("Preview controller is not available.")
return
}
let alert = UIAlertController(title: "Recording Finished", message: "Would you like to edit or delete your recording?", preferredStyle: .alert)
let deleteAction = UIAlertAction(title: "Delete", style: .destructive, handler: { (action: UIAlertAction) in
self.recorder.discardRecording(handler: { () -> Void in
print("Recording suffessfully deleted.")
})
})
let editAction = UIAlertAction(title: "Edit", style: .default, handler: { (action: UIAlertAction) -> Void in
preview?.previewControllerDelegate = self
self.present(preview!, animated: true, completion: nil)
})
alert.addAction(editAction)
alert.addAction(deleteAction)
self.present(alert, animated: true, completion: nil)
self.isRecording = false
self.viewReset()
}
}
func previewControllerDidFinish(_ previewController: RPPreviewViewController) {
dismiss(animated: true)
}
}
