If you've completed your other projects, why not take the time to learn Objective-C? There is a ton of material out on the web to help you get started. Honestly, it won't be that hard and learning to do some memory management will be a great learning exercise. Have you programmed in C before?

Most cross compilers won't do a great job in converting your code, and debugging your project may become much more difficult if you develop them this way.

I think your teacher sent you down the wrong path.

This is a classic example of trying to put a square peg into a round hole. The best way to develop for the iPhone is with the iPhone SDK and objective C. The best way to develop for Andriod is Java and the Android SDK. The best way to develop for WinMobile is C#/VB and the .Net Framework.

As you can see each has their own "best" SDK. Since you are only learning Java I would second the suggestion to play around with Java and Android.

If you plan on integrating app functionality with a website, I'd highly recommend the GWT + PhoneGap model:

Here's my two cents from my own experience: We use the same Java POJOs for our Hibernate database, our REST API, our website, and our iPhone app. The workflow is simple and beautiful:

Database ---1---> REST API ---2---> iPhone App / Website

<ul>
<li>1: Hibernate</li>
<li>2: GSON Serialization and GWT JSON
Deserialization</li>
</ul>

There is another benefit to this approach as well - any Java code that can be compiled with GWT and any JavaScript library become available for use in your iPhone app.

Even if the question states Java, most of the answers have digressed. So I thought I would do the same :)

We have been using Adobe AIR for the last 5 years and it is truly cross-platform and provides native-like performance with the same code base (at least 99% of our code is the same). Adobe AIR got some bad press at the beginning during the 'beta' period (slow, no GPU, Flash 'dead' etc.) But now, it's amazing what you can do with it. Not to mention the wealth of open source libs out there.

With the same code base you can push your app onto:

<ul>
<li>iOS</li>
<li>Android (x86 and ARM)</li>
<li>Flash (still VERY useful)</li>
<li>ChromeBook</li>
<li>PC (as native with installer)</li>
<li>Mac (as native with installer) </li>
</ul>

Why bother with Java or Objective-C ?

The only common platform not covered is Window Phone. But that's coming soon too.

Build a hybrid app. Anyways Java is not enough for a software engineer , you need to learn JS,HTML5,CSS as well for becoming a full stack mobile/app developer.
Build the complete backend using Java &amp; frontend using Cordova/Phonegap.

I'm assuming you dont need the last drop of juice from the hardware even hybind app should suffice your needs.

Build a responsive webapp using Bootstrap 4 + React JS. Use <a href="https://github.com/ipselon/structor" rel="nofollow noreferrer">https://github.com/ipselon/structor</a> to quickly build up the frontend. Now the web app becomes an app in the browser.

You could also take the same app and build it using cordova to publish a app on ios/android platform.

I was wondering if is it possible to develop iPhone applications using Java plus XMLV, which claims to cross-compile Java-based Android applications to native iPhone applications.
Is XMLV a viable way to develop iPhone applications using Java?
Here are a few Java code examples used to build and application in an iPhone:

How can one develop iPhone apps in Java?

我想知道是否有可能使用Java plus XMLV开发iPhone应用程序，它声称可以将基于Java的安卓应用程序交叉编译为本机iPhone应用程序。XMLV是一种使用Java语言开发iPhone应用程序的可行方法吗？下面是一些用于在iPhone中构建和应用程序的代码示例：
