我正在尝试使用UISegmentedControl更改UI中的语言，我想将其他实例作为ViewControler类的属性，例如
private let speechRecognizer_en = SFSpeechRecognizer(locale: Locale.init(identifier: "en-US")) //1
private let speechRecognizer_fr = SFSpeechRecognizer(locale: Locale.init(identifier: "fr-BE")) //1
这是一种方法，但是可以肯定的是，我肯定不知道这是最好的方法。你们大家能给我一个更好的主意，我该怎么办？
这是应用程序源代码，我们可以输入用户曾经用英语说的内容，但我们希望为用户提供更改语言的选项：
import UIKit
import Speech
class ViewController: UIViewController {
@IBOutlet weak var segView: UISegmentedControl!
@IBOutlet weak var startStopBtn: UIButton!
@IBOutlet weak var textView: UITextView!
private Let speechRecognizer = SFSpeechRecognizer(locale: Locale.init(identifier: "en-US")) //1
private Let recognitionRequest: SFSpeechAudioBufferRecognitionRequest?
private Let recognitionTask: SFSpeechRecognitionTask?
private Let audioEngine = AVAudioEngine()
override func viewDidLoad() {
super.viewDidLoad()
startStopBtn.isEnabled = false //2
speechRecognizer?.delegate = self as? SFSpeechRecognizerDelegate //3
SFSpeechRecognizer.requestAuthorization { …我正在尝试录制视频，然后将其保存在 IOS 设备上，我可以录制它，但我想知道如何将其保存在设备上？
import UIKit
import AVKit
import MobileCoreServices
class ViewController: UIViewController , UIImagePickerControllerDelegate , UINavigationControllerDelegate {
@IBOutlet weak var RecordButton: UIButton!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
@IBAction func RecordAction(_ sender: UIButton) {
if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.camera) {
print("Camera Available")
let imagePicker = UIImagePickerController()
imagePicker.delegate = self
imagePicker.sourceType = .camera
imagePicker.mediaTypes = [kUTTypeMovie as String]
imagePicker.allowsEditing = false
self.present(imagePicker, animated: true, completion: nil)
} else {
print("Camera UnAvaialable") …当我们按下它时,下面的代码中存在Keyup事件的错误,它适用于所有浏览器exets IE9你是否对此有所了解:
// on 'enter' in any input field, do the search
$("input, select", _this.sbox).keyup(function(event) {
if (event.keyCode == 13) _this.doSearch();
});
