在IOS AVFoundation中以纵向模式保存/捕获照片,可以通过以下步骤实现:
以下是一个示例代码:
import AVFoundation
func capturePhoto() {
let captureSession = AVCaptureSession()
guard let captureDevice = AVCaptureDevice.default(for: .video) else {
print("Failed to get the camera device")
return
}
guard let input = try? AVCaptureDeviceInput(device: captureDevice) else {
print("Failed to create input device")
return
}
let photoOutput = AVCapturePhotoOutput()
if captureSession.canAddInput(input) && captureSession.canAddOutput(photoOutput) {
captureSession.addInput(input)
captureSession.addOutput(photoOutput)
let photoSettings = AVCapturePhotoSettings()
photoSettings.isHighResolutionPhotoEnabled = true
photoSettings.flashMode = .auto
if let connection = photoOutput.connection(with: .video) {
connection.videoOrientation = .portrait
}
photoOutput.capturePhoto(with: photoSettings, delegate: self)
}
}
extension YourViewController: AVCapturePhotoCaptureDelegate {
func photoOutput(_ output: AVCapturePhotoOutput, didFinishProcessingPhoto photo: AVCapturePhoto, error: Error?) {
if let imageData = photo.fileDataRepresentation() {
if let image = UIImage(data: imageData) {
// 处理照片
// ...
// 保存照片到相册
UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil)
}
}
}
}
这段代码使用AVCaptureSession来管理捕获会话,AVCaptureDevice作为输入源,AVCapturePhotoOutput用于捕获照片输出。在回调中,可以处理照片数据并保存到相册。
