A/B testing Xamarin.iOS apps with Leanplum

via A/B testing Xamarin.iOS apps with Leanplum — Medium.

As applications move to maturity, A/B testing provides a great mechanism to polish the user experience and optimize your application to promote certain actions or behaviors. While A/B testing has been used extensively on the web, until recently, it had been impractical for mobile due to the app submission/approval process. Naturally, tools like Optimizely, Apptimize, and Leanplum have emerged to address this pain point. Of the three, my preference goes to the last, since they provide a very solid analytics and marketing automation features as well (along with amazing support). Still, I’ll be addressing mostly the A/B testing side of things in this post.

Using Auto Layouts for iOS 9 SplitView

via Using Auto Layouts for iOS 9 SplitView | Xamarin Blog.

The official launch of iOS 9 is on the horizon, which makes it a great time to ensure your Xamarin.iOS app is ready to take advantage of all of the upcoming features. One that I’m excited about is the new and improved multi-tasking experience on the iPad. With iOS 9, it’s possible to run two apps side-by-side in a split view on the iPad. This means that your app can’t assume that it’s going to have the device’s full resources, or, more importantly, the entire screen. If you already use Auto Layouts for your apps, then you’re all set to take advantage of split view on the iPad, but if your app is using the older layout option of Autoresizing, you’ll want to transition to Auto Layouts as soon as possible to make sure you’re ready for the change.

Put Some Azure Active Directory in Xamarin.Forms

via Put Some Azure Active Directory in Xamarin.Forms | Xamarin Blog.

he Azure Active Directory Authentication Library (aka ADAL) makes authentication with Azure Active Directory a breeze. We’ve already covered usage of ADAL in various posts on authenticating with Active Directory, adding storage, and adding collaboration (SharePoint) to your mobile apps.
ADAL is available for various platforms and supports Xamarin.Android, Xamarin.iOS, and Windows Phone. It’s easy to integrate ADAL into these projects by adding a NuGet package. Although ADAL hasn’t released a specific Package for Xamarin.Forms, there have been many questions in the Xamarin forums and on StackOverflow about how to use ADAL in a Xamarin.Forms app.

Recently, Vittorio Bertocci, Principal Program Manager at Microsoft, posted ablog about integrating ADAL into Xamarin.Forms apps using a PageRenderer. In this post, I’ll be sharing another way to integrate ADAL into Xamarin.Forms apps using Dependency Service, which is available in Xamarin.Forms.

Customize Your Xamarin.Forms App With Pages For Each Platform

via Customize Your Xamarin.Forms App With Pages For Each Platform | Xamarin Blog.

When I was building Moments, a Snapchat clone built with Xamarin.Forms and Microsoft Azure, I needed a way to show a live, in-app camera feed so users could take all the selfies their hearts desire without having to leave the app to take a photo. This type of camera access is possible in traditional Xamarin.iOS and Xamarin.Android development, which I learned how to do from our Xamarin recipes, but I knew that this type of camera access wasn’t part of Xamarin.Forms’ out-of-the-box 40+ controls, layouts, and pages.

Luckily, not only can you extend existing controls and build your own controls in Xamarin.Forms, you can also render platform-specific pages from within your Xamarin.Forms apps. This was the type of customization that I needed, and it was surprisingly simple to implement.
