Open up the code editor and, in Global.js, create an array with the correct time images you have e.g.
window.globalVar = "timepics";
timepics = [
assets/timepic1.png,
assets/timepic2.png
];
However many images you have put a comma at the end of each line except the last in your array list. Put your timepic1.png, timepic2.png, etc images in the assets panel in your iAd project.
Create and import an image the same size as your timepic images. This image, when tapped will be replaced with the correct answer. Because it needs to be tapped, it can't be transparent, but it could be styled as a button with "Check!" or something written in the middle. Add this code to the image in the code editor, deleting whatever code might appear there when you first open up the code editor:
this.onViewTouchDown = function (event) {
this.viewController.startActionWithSourceView({
"className" : "iAP.ImageSourceAction",
"delay" : 0,
"properties" : {
"duration" : 0.0001,
"targetViewId" : "Page1-MyImageName",
"url" : timepics[0], // This is timepic1.png (remember that the first item in an array is at index 0, not 1!)
"height" : 165, //change this to whatever your image height is
"width" : 173 //change this to whatever your image width is
}
}, this);
};
The MyImageName value of your tappable image is the Properties > Name value in the iAd Inspector. Replace MyImageName in the code with whatever appears there.
