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，但由于某些原因在iOS设备上安装时会崩溃应用程序。在iOS模拟器中调用相机时，它会失败。（因为模拟器显然没有相机）。这个问题有什么解决方案吗？

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>

的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);

的Config.xml

 <?xml version='1.0' encoding='utf-8'?>
 <widget id="com.MakeMePretty.joshua" version="1.0.0" 
 xmlns="http://www.w3.org/ns/widgets"

Answer 1

请将以下行添加到您的Info.plist中作为源代码：

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

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

可以找到更详细的解释，作为对此问题的回复：NSCameraUsageDescription in iOS 10.0 runtime crash?
