Xamarin Forms iOS应用突然启动时崩溃

Question

My Xamarin Forms iOS app was working fine. Suddenly it started crashing on launch of the app. The debug point is not even hitting app delegate or app.xaml.cs. I tried changing few iOS configs. I tried removing all packages and added them back to check. Also, I check both in simulator and device. Also, in iPad and iPhone versions.

The same code is working for Android. Can you please guide me how to go about this scenario and how to figure out where the problem is?

Is it possible to stop working suddenly like this?

Answer 1

It seems in Main.cs, line of AppDelegate reference got commented out somehow. That is the reason for the crash.

Answer 2

Have you tried using exception handling? it's really usefull in this situation.

    try ()
{
//your code
}
catch(exception e)
{
Messagebox.Show(e);
}
