If you are new to the Xamarin world and are still hesitating what approach to take for developing your application, you should familiarize yourself with the strengths and weaknesses of the available approaches for developing Xamarin applications. We are here summarizing the main points discussed in the Xamarin.Forms introduction page.
Using this approach you can quickly achieve similar look and feel on all available platforms by sharing the same code base. All controls and views are eventually translated to platform-specific native elements without the need of any further actions from your side. You should consider this approach for:
Apps that require little platform-specific functionality
Apps where code sharing is more important than custom UI and platform-specific features
You feel comfortable creating your UI through XAML
If you choose this approach, you should refer to the available custom controls from the Xamarin Forms Controls section.
For more details check the official Xamarin.Forms documentation.
By choosing this approach, you can take full advantage of each platform. You are free to create platform-specific views to achieve the desired appearance in the smallest details. You can access native APIs and utilize device-specific features. You should consider this approach for:
Apps that require native behavior
Apps that need to use platform-specific APIs
Apps where you need to achieve custom UI according to the target platform
Aside from the Xamarin.Forms control that the Progress Telerik UI for Xamarin suite provides, you can take advantage of the Native Controls Wrappers.
The Android Wrappers are built on top of the truly native controls from the UI for Android suite(discontinued as a separate product as of April 20th 2017). The following controls are available for Xamarin.Android development:
The iOS Wrappers are built on top of the truly native controls from the UI for iOS suite(discontinued as a separate product as of April 20th 2017). The following controls are available for Xamarin.iOS development:
Though the UI for iOS and UI for Android suites have been discontinued as available products we are using them as basis for the Xamarin.Android and Xamarin.iOS controls. With this in mind, we are still dedicated to improving their quality and features so they fit nicely and provide smooth development experience in the Xamarin world.
