Question

我正试图通过iphone访问相机而我不知道该怎么做。

我有一个<button>点击后我想在iphone上访问相机。

有人可以向我解释我该怎么办？

Answer 1

使用import Camera from 'react-native-camera';

然后创建一个方法，

takePicture() {
    this.camera.capture()
      // some service action if you want to use... 
      .then(data => {
        .........
      // this is for vibrating device while taking photo
        Vibration.vibrate();
        ..........
      });
  }

您需要添加权限

<uses-permission android:name="android.permission.VIBRATE"/>

    <uses-permission android:name="android.permission.CAMERA" />
    <uses-feature android:name="android.hardware.camera" />
    <uses-feature android:name="android.hardware.camera.autofocus" />




async function requestCameraPermission() {
      try {
        const granted = await PermissionsAndroid.request(
          PermissionsAndroid.PERMISSIONS.CAMERA,
          {
            'title': 'Cool Photo App Camera Permission',
            'message': 'Cool Photo App needs access to your camera ' +
                       'so you can take awesome pictures.'
          }
        )
        if (granted === PermissionsAndroid.RESULTS.GRANTED) {
          alert("You can use the camera")
        } else {
          alert("Camera permission denied");
        }
      } catch (err) {
        alert(err)
      }
    }
