ios5 - Phonegap/Cordova 不显示摄像头

Question

我的第一个 ios phonegap/cordova 应用程序有一个奇怪的问题

我复制粘贴了示例 http://docs.phonegap.com/en/2.3.0/cordova_camera_camera.md.html#camera.getPicture

和

http://docs.phonegap.com/en/2.3.0/cordova_media_capture_capture.md.html#capture.captureImage

但是当我按下任何按钮时，没有任何反应，除非我随后双击 iphone 上的“主页”按钮。

这是我的 index.html:

    <script src="assets/js/cordova.ios.js"></script>

    <script type="text/javascript" charset="utf-8">
    var pictureSource;   // picture source
    var destinationType; // sets the format of returned value 

    // Wait for Cordova to connect with the device
    document.addEventListener("deviceready", onDeviceReady, false);

    // Cordova is ready to be used!
    function onDeviceReady() {
        pictureSource = navigator.camera.PictureSourceType;
        destinationType = navigator.camera.DestinationType;
    }

    // Called when a photo is successfully retrieved
    function onPhotoDataSuccess(imageData) {
        // Uncomment to view the base64 encoded image data
        // console.log(imageData);

        // Get image handle
        var smallImage = document.getElementById('smallImage');

        // Unhide image elements
        smallImage.style.display = 'block';

        // Show the captured photo
        // The inline CSS rules are used to resize the image
        smallImage.src = "data:image/jpeg;base64," + imageData;
    }

    // Called when a photo is successfully retrieved
    function onPhotoURISuccess(imageURI) {
        // Uncomment to view the image file URI 
        // console.log(imageURI);

        // Get image handle
        var largeImage = document.getElementById('largeImage');

        // Unhide image elements
        largeImage.style.display = 'block';

        // Show the captured photo
        // The inline CSS rules are used to resize the image
        largeImage.src = imageURI;
    }

    // A button will call this function
    function capturePhoto() {
        // Take picture using device camera and retrieve image as base64-encoded string
        navigator.camera.getPicture(onPhotoDataSuccess, onFail, {
            quality: 50,
            destinationType: destinationType.DATA_URL
        });
    }

    // A button will call this function
    function capturePhotoEdit() {
        // Take picture using device camera, allow edit, and retrieve image as base64-encoded string  
        navigator.camera.getPicture(onPhotoDataSuccess, onFail, {
            quality: 20, allowEdit: true,
            destinationType: destinationType.DATA_URL
        });
    }

    // A button will call this function
    function getPhoto(source) {
        // Retrieve image file location from specified source
        navigator.camera.getPicture(onPhotoURISuccess, onFail, {
            quality: 50,
            destinationType: destinationType.FILE_URI,
            sourceType: source
        });
    }

    // Called if something bad happens.
    function onFail(message) {
        alert('Failed because: ' + message);
    }
    </script>
    <button onclick="capturePhoto();">Capture Photo</button>  
    <button onclick="capturePhotoEdit();">Capture Editable Photo</button>  
    <button onclick="getPhoto(pictureSource.PHOTOLIBRARY);">From Photo Library</button>  
    <button onclick="getPhoto(pictureSource.SAVEDPHOTOALBUM);">From Photo Album</button>  
    <img style="display:none;width:60px;height:60px;" id="smallImage" src="" />  
    <img style="display:none;" id="largeImage" src="" />  


    <script type="text/javascript" charset="utf-8">

    // Called when capture operation is finished
    function captureSuccess(mediaFiles) {
        //var i, len;
        //for (i = 0, len = mediaFiles.length; i < len; i += 1) {
        //    //uploadFile(mediaFiles[i]);
        //}
        //navigator.notification.alert('Weee', null, 'Great success!');
    }

    // Called if something bad happens.
    function captureError(error) {
        //var msg = 'An error occurred during capture: ' + error.code;
        //navigator.notification.alert(msg, null, 'Uh oh!');
    }

    // A button will call this function
        function captureImage() {
        // Launch device camera application, 
        // allowing user to capture up to 2 images
        navigator.device.capture.captureImage(captureSuccess, captureError, { limit: 2     });
    }

    // Upload files to server
    function uploadFile(mediaFile) {
        var ft = new FileTransfer(),
            path = mediaFile.fullPath,
            name = mediaFile.name;

        ft.upload(path,
            "http://my.domain.com/upload.php",
            function (result) {
                console.log('Upload success: ' + result.responseCode);
                console.log(result.bytesSent + ' bytes sent');
            },
            function (error) {
                console.log('Error uploading file ' + path + ': ' + error.code);
            },
            { fileName: name });
    }
    </script>

    <button onclick="captureImage();">Capture Image</button> 

这是我的 config.xml:

有人知道我做错了什么吗？

是的!我终于让它工作了，我从 phonegap 2.3.0 降级到 2.0.0

对于有同样问题的人，这里是我的最终代码:

index.html

    <script src="assets/js/cordova-2.0.0.js"></script>
    <script type="text/javascript" charset="utf-8">

        // Called when capture operation is finished
        //
        function captureSuccess(mediaFiles) {
            //var i, len;
            //for (i = 0, len = mediaFiles.length; i < len; i += 1) {
            //    //uploadFile(mediaFiles[i]);
            //}
            //navigator.notification.alert('Weee', null, 'Great success!');
        }

        // Called if something bad happens.
        // 
        function captureError(error) {
            //var msg = 'An error occurred during capture: ' + error.code;
            //navigator.notification.alert(msg, null, 'Uh oh!');
        }

        // A button will call this function
        //
        function captureImage() {
            // Launch device camera application, 
            // allowing user to capture up to 2 images
            navigator.device.capture.captureImage(captureSuccess, captureError, { limit: 2 });
        }

        // Upload files to server
