iOS，从代码中检测临时内容

iOS是苹果公司开发的操作系统，广泛应用于iPhone、iPad和iPod Touch等移动设备上。在iOS开发中，我们经常需要检测临时内容，以便进行相应的处理和操作。本文将介绍如何在iOS代码中检测临时内容，并通过自然语言生成一篇文章来详细说明这个过程。

swift
func isValidEmail(email: String) -> Bool {
    let emailRegex = "[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,}"
    let emailPredicate = NSPredicate(format:"SELF MATCHES %@", emailRegex)
    return emailPredicate.evaluate(with: email)
}
let email = "test@example.com"
if isValidEmail(email: email) {
    print("Valid email address")
} else {
    print("Invalid email address")
}

swift
import CoreML
import Vision
func detectObjectsInImage(image: UIImage) {
    guard let model = try? VNCoreMLModel(for: MobileNetV2().model) else {
        return
    }
    
    let request = VNCoreMLRequest(model: model) { (request, error) in
        guard let results = request.results as? [VNClassificationObservation] else {
            return
        }
        
        for result in results {
            print("\(result.identifier): \(result.confidence)")
        }
    }
    
    let handler = VNImageRequestHandler(cgImage: image.cgImage!, options: [:])
    try? handler.perform([request])
}
let image = UIImage(named: "example.jpg")
detectObjectsInImage(image: image)

swift
import AVFoundation
func detectSpeechInAudio(audioURL: URL) {
    let recognizer = SFSpeechRecognizer(locale: Locale(identifier: "en-US"))
    let request = SFSpeechURLRecognitionRequest(url: audioURL)
    
    recognizer?.recognitionTask(with: request) { (result, error) in
        guard let result = result else {
            return
        }
        
        if result.isFinal {
            print(result.bestTranscription.formattedString)
        }
    }
}
let audioURL = Bundle.main.url(forResource: "example", withExtension: "m4a")
detectSpeechInAudio(audioURL: audioURL)
