将捕获的图像存储到UIImage数组(AVFoundation)中,可以通过以下步骤实现:
以下是一个示例代码:
import AVFoundation
class ImageCaptureManager: NSObject, AVCaptureVideoDataOutputSampleBufferDelegate {
var imageArray: [UIImage] = []
var captureSession: AVCaptureSession?
func startCapture() {
captureSession = AVCaptureSession()
guard let captureSession = captureSession else {
return
}
guard let captureDevice = AVCaptureDevice.default(for: .video) else {
return
}
do {
let input = try AVCaptureDeviceInput(device: captureDevice)
captureSession.addInput(input)
let output = AVCaptureVideoDataOutput()
output.setSampleBufferDelegate(self, queue: DispatchQueue.main)
captureSession.addOutput(output)
captureSession.startRunning()
} catch {
print("Error setting up capture session: \(error.localizedDescription)")
}
}
func stopCapture() {
captureSession?.stopRunning()
captureSession = nil
}
func captureOutput(_ output: AVCaptureOutput, didOutput sampleBuffer: CMSampleBuffer, from connection: AVCaptureConnection) {
guard let imageBuffer = CMSampleBufferGetImageBuffer(sampleBuffer) else {
return
}
let ciImage = CIImage(cvPixelBuffer: imageBuffer)
let context = CIContext()
guard let cgImage = context.createCGImage(ciImage, from: ciImage.extent) else {
return
}
let image = UIImage(cgImage: cgImage)
imageArray.append(image)
}
}
// 使用示例
let captureManager = ImageCaptureManager()
captureManager.startCapture()
// 在需要停止捕获时调用
captureManager.stopCapture()
在上述示例代码中,我们创建了一个ImageCaptureManager类,该类负责捕获图像并将其存储到UIImage数组中。通过调用startCapture()方法,可以开始捕获图像;通过调用stopCapture()方法,可以停止捕获图像。在代理方法captureOutput(_:didOutput:from:)中,我们将捕获到的图像数据转换为UIImage对象,并将其添加到imageArray数组中。
请注意,上述示例代码仅涉及图像捕获和存储部分,其他相关功能(如图像处理、网络传输等)需要根据具体需求进行实现。
