This code units up a primary page-based navigation system for switching between totally different cases of filtercameraViewController. When you’ve got particular questions or want additional help with this code, please let me know.
that is my code for web page view controller for digital camera views like photographic types.
`
import UIKit
import AVFoundation
class filterViewController: UIPageViewController, UIPageViewControllerDelegate, UIPageViewControllerDataSource {
var cameraViewControllers: [UIViewController] = []
override func viewDidLoad() {
tremendous.viewDidLoad()
self.dataSource = self
self.delegate = self
// Add your digital camera view controllers
let camera1ViewController = filtercameraViewController()
let camera2ViewController = filtercameraViewController()
let camera3ViewController = filtercameraViewController()
cameraViewControllers = [camera1ViewController, camera2ViewController, camera3ViewController]
if let firstView = cameraViewControllers.first {
setViewControllers([firstView], route: .ahead, animated: true, completion: nil)
}
}
// In filterViewController
func setPageSize() {
// Set the web page measurement to match the dimensions of filtercameraViewController
let pageWidth = UIScreen.predominant.bounds.width
let pageHeight = UIScreen.predominant.bounds.top / 5.0 // Regulate as wanted
self.view.body = CGRect(x: 0, y: 0, width: pageWidth, top: pageHeight)
}
func pageViewController(_ pageViewController: UIPageViewController, viewControllerBefore viewController: UIViewController) -> UIViewController? {
guard let currentIndex = cameraViewControllers.firstIndex(of: (viewController as? filtercameraViewController)! ) else { return nil }
let previousIndex = currentIndex - 1
if previousIndex < 0 {
return nil
}
return cameraViewControllers[previousIndex]
}
func pageViewController(_ pageViewController: UIPageViewController, viewControllerAfter viewController: UIViewController) -> UIViewController? {
guard let currentIndex = cameraViewControllers.firstIndex(of: (viewController as? filtercameraViewController)!) else { return nil }
let nextIndex = currentIndex + 1
if nextIndex >= cameraViewControllers.depend {
return nil
}
return cameraViewControllers[nextIndex]
}
override init(transitionStyle model: UIPageViewController.TransitionStyle, navigationOrientation: UIPageViewController.NavigationOrientation, choices: [UIPageViewController.OptionsKey: Any]? = nil) {
tremendous.init(transitionStyle: .scroll, navigationOrientation: .horizontal, choices: nil)
}
required init?(coder: NSCoder) {
fatalError("init(coder:) has not been carried out")
}
}`
The code initializes the digital camera view, units up the digital camera with an AVCaptureSession, and provides AVCaptureDevice enter and AVCapturePhotoOutput to the session. It additionally units up a preview layer for the digital camera view.
`import UIKit
import AVFoundation
class filtercameraViewController: cameraViewController {
// var CameraView : UIView!
override func viewDidLoad() {
tremendous.viewDidLoad()
cameraView = UIView ()
cameraView.translatesAutoresizingMaskIntoConstraints = false
view.addSubview(cameraView)
//CameraView.backgroundColor = .black
let X: CGFloat = 40.0
let Y: CGFloat = 40.0
// let X: CGFloat = 60.0
let x : CGFloat = 140.0
NSLayoutConstraint.activate([
cameraView.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: Y),
cameraView.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: -Y),
cameraView.topAnchor.constraint(equalTo: view.topAnchor, constant: X),
cameraView.bottomAnchor.constraint(equalTo: view.bottomAnchor, constant: -x)
])
captureSession = AVCaptureSession()
// captureSession.sessionPreset = currentAspectRatio
if let gadget = AVCaptureDevice.default(for: .video) {
do {
let enter = strive AVCaptureDeviceInput(gadget: gadget)
if ((captureSession.canAddInput(enter)) ) {
captureSession.addInput(enter)
}
stillImageOutput = AVCapturePhotoOutput() // Initialize it as an AVCapturePhotoOutput
if ((captureSession.canAddOutput(stillImageOutput!))) { // Unwrap the optionally available
captureSession.addOutput(stillImageOutput!)
}
previewLayer = AVCaptureVideoPreviewLayer(session: captureSession!)
cameraView?.layer.addSublayer(previewLayer)
DispatchQueue.international(qos: .userInitiated).async {
self.captureSession.startRunning()
}
} catch {
print("Error establishing digital camera: (error)")
}
}
}
}

That is the primary class of my code right here is in have button to open pages. after opening pages it may apply a filters i put's small little bit of code ..thats sufficient for you i believe :
import UIKit
import AVFoundation
import Pictures
import CoreMotion
class cameraViewController: UIViewController,AVCapturePhotoCaptureDelegate, UIGestureRecognizerDelegate {
var cameraView: UIView!
var captureButton: UIButton!
var cameraSwitchButton: UIButton!

var previewLayer: AVCaptureVideoPreviewLayer!
var currentZoomFactor: CGFloat = 1.0
var maxZoomFactor: CGFloat = 5.0
var zoomStep: CGFloat = 1.0
var currentFlashMode: AVCaptureDevice.FlashMode = .auto // set flash mode on auto
var isFlashOn: Bool = false
// var exposurePoint = CGPoint(x: 0.5, y: 0.5)

var currentFocusLevel: Float = 0.0 // calculate
var motionManager: CMMotionManager!
var yawAngle: Double = 0.0
var segmentedControll : UISegmentedControl! // phase controll for choose a side ratio
var currentAspectRatio: AVCaptureSession.Preset = .hd1920x1080 // set default aspet ratio on seize session
var timerButton : UIButton!
var timerDuration: TimeInterval = 0
var timerLabel: UILabel!
var timer : Timer?
var styleButton : UIButton!
var gadget : AVCaptureDevice!
var lastManualExposureValue: Float = 0.0
var index : Int = 0
// var pageViewController: UIPageViewController!
var isStyleViewActive = false
var cameraViewControllers: [cameraViewController] = []
override func viewDidLoad() {

}
//it was utilizing for cover standing bar on show eg:battery standing,singnal
override var prefersStatusBarHidden: Bool{
return true
}
override var supportedInterfaceOrientations: UIInterfaceOrientationMask {
return .portrait
}
override func viewDidAppear(_ animated: Bool) {
tremendous.viewDidAppear(animated)
previewLayer?.connection?.videoOrientation = currentVideoOrientation()
previewLayer?.body = cameraView.bounds
// previewLayer.videoGravity = .resizeAspect
}
override func viewWillTransition(to measurement: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {
}
func setupCameraView() {
cameraView = UIView()
cameraView.translatesAutoresizingMaskIntoConstraints = false
view.addSubview(cameraView)

I've created an iOS digital camera app with a predominant digital camera view, and I need to add assist for various digital camera modes or types, much like the photographic types in iPhone 13. Every mode ought to have its personal set of digital camera settings and UI parts.
What's the easiest way to implement this function in my iOS app? Are you able to present some steering or code examples on tips on how to create totally different digital camera modes and swap between them?
I am in search of recommendation on the general structure and tips on how to deal with digital camera settings and UI transitions between modes successfully. Any suggestions, code snippets, or references to related documentation could be drastically appreciated.
Thanks!
