In my previous blogpost I created a small PoC to show you how to work with the Azure Custom Vision Service and WinML. In this blogpost we are going to take the same model that I have trained back then, export it as a CoreML model and use it in iOS using Xamarin. I was… Read More »
I needed a simple control that could show a hyperlink inline with other text and I’d like the link to be defined in markdown. In short, something like this: HyperlinkLabel In Xamarin.Forms, I created a HyperlinkLabel class which isn’t anything more than a class inheriting from the standard Label with an additional bindable property RawText. It also… Read More »
Last week I gave a talk about Realm at the Xamarin Expert Day in Cologne, Germany. Some people asked me if I could put the code of the demos, that I used in this talk, on a public GitHub Repo. Sharing is caring, of course! 🙂 ShoppingList – Basic Realm Mobile DB demo (local storage) ShoppingList – Realm Mobile DB… Read More »
Realm offers a nice technique to share Realms with other users using the PermissionOffer and the PermissionOfferResponse objects. The idea is that you can provide a token that an other user can use to connect to your data store. In this blogpost we will use this flow in combination with a QR code -generated by ZXing- to let an other user connect… Read More »

Like I did today… The ‘problem’ with the Picker You might have noticed that when you are binding to the SelectedItem of a Picker in Xamarin Forms, that on iOS the value of the bound property already changes when the user is scrolling through the… Read More »

In this blogpost I would like to share how I recently set up localization in a Xamarin Froms app. With this approach, I am able to bind to items in… Read More »
Xamarin Forms supports binding to indexed properties. But do you know how to trigger a PropertyChanged event on such a property so that the binding engine gets the updated value? Binding to indexed properties Binding to an indexed property in Xamarin Forms is simple. Imagine my ViewModel has an indexed property:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
Dictionary<string, string> Data { get; } = new Dictionary<string, string>() { { "123", "Pie" }, { "456", "Eating" }, { "789", "Ninjas" } }; public string this[string id] { get { return Data[id]; } } |
I can simply bind… Read More »
Lately I’ve been playing around with Realm. Realm is a very cool platform that allows us to easily build mobile apps that use things like local data storage, two-way data synchronisation, real time collaboration, … Things that typically require some coding if you want to do it yourself! After doing some test with local data storage… Read More »
When I was building a Xamarin PoC at the client, I was disappointed to notice that there wasn’t any way of simulating the user’s location on the Remoted iOS Simulator for Windows. Not to mention simulating a walk or bike ride around an area other then the standard rides around Apple’s headquarters. Setting a custom… Read More »
Preface (you can skip this if you are not interested in the underlying idea, no hard feelings!) A while ago my brother -who sells windows (no, not the OS) and doors- asked me if I could build a small app for his business. The key feature he wanted to have in his app is a map… Read More »
