Ibm Worklight have samples that calling the native app, but that was created in worklight itself eg: module_09_1_Android_CombiningNativeAndWebPages in this sample in android
Why write code that will work on Android and not on iPhone? Worklight uses PhoneGap, so you can use camera.getPicture and get to your application the image taken with the camera as base64.
navigator.camera.getPicture( cameraSuccess, cameraError, [ cameraOptions ] );
See PhoneGap documentation for more information (http://docs.phonegap.com/en/1.0.0/phonegap_camera_camera.md.html).
Use this function in your applicaton. By default Cordova plugin is installed in worklight application. you need to just call its functionality
function takePicture() {
navigator.camera.getPicture(
function(data) {
var img = dom.byId('camera_image');
img.style.visibility = "visible";
img.style.display = "block";
//img.src = "data:image/jpeg;base64," + data;
img.src = data;
dom.byId('camera_status').innerHTML = "Success";
},
function(e) {
console.log("Error getting picture: " + e);
dom.byId('camera_status').innerHTML = e;
dom.byId('camera_image').style.display = "none";
},
{ quality: 50, destinationType: navigator.camera.DestinationType.FILE_URI, sourceType : navigator.camera.PictureSourceType.CAMERA});
};
