如何在App内使用Camera Control 拍照

To use Camera Control to take photos within an app, you can follow the steps outlined in the session "Enhancing your camera experience with capture controls" from WWDC 2025. Here’s a brief overview of the process:

1. Set Up AVCapture Session: Begin by creating an AVCapture session and adding a capture device as an input. This is the foundation for using camera controls.

2. Add Camera Controls: You can add system-defined controls to your AVCapture session. These controls can be used to manage camera properties like zoom and exposure. For example, you can use Camera Control as a shutter button to take photos.

3. Configure Event Handling: Use the AVCapture Event Interaction API to handle physical button presses, such as using the volume buttons as a shutter button. This allows you to map physical button gestures to camera actions, providing a familiar user experience similar to the native iOS camera app.

4. Update UI with KVO: If you are using Key Value Observing (KVO), you can update your UI when camera properties change. Alternatively, you can create system controls with action handlers to update the UI directly.

For more detailed guidance, you can refer to the session Enhancing your camera experience with capture controls (10:00) which covers the use of Camera Control in detail.
