蘋果閃光燈怎麼開
To turn on the flashlight on an iPhone, follow these steps:
1. Unlock your iPhone and go to the home screen.
2. Swipe down from the top right corner of the screen to open the Control Center.
3. Look for the flashlight icon, which looks like a small flashlight or a lightning bolt.
4. Tap on the flashlight icon to turn it on. You can adjust the brightness by pressing and holding the flashlight icon.
5. To turn off the flashlight, simply tap the flashlight icon again.
If you are looking to control the flashlight programmatically in an iOS app, you can use the following Swift code snippet:
```swift
import UIKit
import AVFoundation
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
}
func toggleFlashlight() {
guard let device = AVCaptureDevice.default(for: AVMediaType.video) else { return }
if device.hasTorch {
do {
try device.lockForConfiguration()
if device.isTorchActive {
device.torchMode = AVCaptureDevice.TorchMode.off
} else {
try device.setTorchModeOn(level: 1.0)
}
device.unlockForConfiguration()
} catch {
print("Error toggling flashlight: (error.localizedDescription)")
}
}
}
}
```
This code snippet demonstrates how to toggle the flashlight on an iOS device using the AVFoundation framework in Swift.
