javascript - Cordova Camera 插件在 iOS 上崩溃

Question

我正在尝试在应用程序中使用 Cordova 相机插件。它在 Android 设备上运行良好，但由于某种原因在 iOS 设备上安装时应用程序崩溃。在iOS模拟器中调用摄像头时失败。(因为模拟器显然没有摄像头)。这个问题有什么解决办法吗？

HTML

<!--Save my look-->
<div id="saveMyLook">
<div id="cameraSection">
<button id="cameraBtn">Lets take a picture</button>
<img id="myImage" width="35%" height="35%" />
</div>
</div>

Javascript

document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
console.log(navigator.camera);
}
var camBtn=document.getElementById("cameraBtn");

function cam (){
    navigator.camera.getPicture(onSuccess, onFail,
    {sourceType: Camera.PictureSourceType.CAMERA});

function onSuccess(imageURI) {
    var image = document.getElementById('myImage');
    image.src = imageURI;
}

function onFail(message) {
    alert( message);
}
}
 camBtn.addEventListener('click',cam);

Answer 1

请将以下行作为源代码添加到您的 Info.plist 中:

<key>NSCameraUsageDescription</key>
<string>Camera usage description</string>


这是因为在 iOS 10 之后，您必须在 Info.plist 中定义并提供您的应用访问的所有系统隐私敏感数据的使用说明。
