Can't use navigator.camera.getPicture on iOS phonegap adobe build
提问by user1044220
I have been looking for hours now and can't get my phonegap app (compiled by adobe phonegap build) and I fear I am missing something about phonegap. I have added the following lines to the config.xml file:
我一直在寻找几个小时，但无法获得我的 phonegap 应用程序（由 adobe phonegap build 编译），我担心我错过了有关 phonegap 的一些信息。我在 config.xml 文件中添加了以下几行：
<feature name="http://api.phonegap.com/1.0/geolocation"/>
<feature name="Camera">
<param name="ios-package" value="CDVCamera" />
</feature>
<feature name="http://api.phonegap.com/1.0/file"/>
<feature name="http://api.phonegap.com/1.0/camera"/>
I try to take the picture using the following code:
我尝试使用以下代码拍照：
navigator.camera.getPicture(function(image) {callback("data:image/jpeg;base64," + image)}, cameraFail, { quality: 49 });
I am testing it by running it on an iPad2 running iOS 7. I've created a rudimentary inapp console and the problem appears to be that navigator.camera does not exist. Thanks for reading hope you can help.
我正在通过在运行 iOS 7 的 iPad2 上运行它来测试它。我创建了一个基本的 inapp 控制台，问题似乎是 navigator.camera 不存在。感谢阅读希望对你有所帮助。

With help from another answer it lead me to realize what I had done wrong so i'll post for anyone else that is in the same boat.
在另一个答案的帮助下，它让我意识到我做错了什么，所以我会为同一条船上的其他人发帖。
I hadn't included a reference to cordova.js which should be done just by adding a normal script tag like this:
我没有包含对cordova.js的引用，这应该通过添加一个像这样的普通脚本标签来完成：
<script src="cordova.js"></script>
I hadn't included it as I did not have the file cordova.js. What I did not realize is when using the adobe Phonegap Build service the file is added automatically and I did not need it in my source directory, just to include the tag.
我没有包含它，因为我没有文件cordova.js。我没有意识到的是，当使用 adobe Phonegap Build 服务时，文件会自动添加，我的源目录中不需要它，只是为了包含标签。

Installing plugins for PhoneGap can be difficult.
为 PhoneGap 安装插件可能很困难。
Do you have the following functions in your code?
您的代码中有以下功能吗？
navigator.camera.getPicture(onSuccess, onFail, { quality: 50,
? ? destinationType: Camera.DestinationType.DATA_URL
?});
function onSuccess(imageData) {
? ? var image = document.getElementById('myImage');
? ? image.src = "data:image/jpeg;base64," + imageData;
}
function onFail(message) {
? ? alert('Failed because: ' + message);
}
Your config.xml seems ok.
你的 config.xml 看起来没问题。
