The most common place to put the call to SetMinimumBackgroundFetchInterval is in your FinishedLaunching delegate method, such as below:. The final step is to implement the PerformFetch delegate method in your AppDelegate declaration. This is the method iOS will invoke to help your app update its content and UI.
This method must finish in 30 seconds, or iOS will likely terminate your app. Below is a sample implementation of PerformFetch which downloads an image and saves it to the personal directory of the app:. So there you have it—a basic iOS app that will periodically wake up your app, fetch an image, and save it to disk. We're Hiring. Atomic Object. By: Matt Rozema. About This Author Over the last few months, I have had the opportunity to work with Xamarin , a platform for writing native mobile apps iOS, Android, Windows in a single, cross-platform implementation.
Implementing Background Fetch with Xamarin 1. Enable Background Fetch. The default interval is BackgroundFetchIntervalNever , which basically means that Background Fetch is disabled by default. You can specify a desired interval, which means that iOS will wait at least the desired amount of time before waking up your app. Setup: Visual Studio Hey everyone!
A new NuGet version has been built which should fix every scenario. I would appreciate if you could verify! Should I also install Xamarin.

I see things are going fast right now haha. I think 32 and 33 should work too There have been a couple of new builds :. I noticed that there is still a small visual issue with the tab bar and the unselected icon color. The burger color is fixed, but it looks like the "tab bar" or at least the placeholder for it is present in a project that is a flyout.
The bottom of the screen shot is white, but the map should be "Stretch"ed to the bottom. Now my app seems to look way better, I only see a bug on tab selected icon color.
The color should be the same as text, but a blueish color is used. I tested also the TabBar template and the icons behaviour is the same just like the way you reported, but the bug is on the selected Icon, not on unselected icons.
Great simonemarra thanks so much for all your efforts! We've tracked the white space for the tab bar, we fixed that and we have an idea on what happens to the icon.
Stay tuned for another update :D. Hey, just tested my app with XF 5. Visuals 5. Thanks for being on top of this simonemarra! I suppose Looks good captain. Great, thanks for confirming biapar!

I expected to get white icons when selected, but I see the "standard" xamarin blue icons Looks like there's an issue when building a "Release". The tab placeholder is showing up on the bottom. Please open a new issue if you think something is still wrong and where possible add details and even better; a reproduction sample. Thanks for letting us know rsbepvb! Skip to content. Forms Public.
