我们开发了适用于iOS和Android的Xamarin Forms应用程序。该应用程序现在已经工作了几个月，并且可以在商店中使用。 但自从我们的应用程序的最后一个发布周期以来，应用程序在启动时崩溃了。 仅在发布模式下发生，仅在实际设备上发生。所有其他组合仍然有效（在模拟器上发布/在设备上调试/ ..）。 我们还试图回滚版本但仍无法构建发布版本。
并且还尝试更改链接器选项。
目前Xamarin或Xcode看起来有变化，但这只是假设。
当我尝试通过Console输出进行调试时，所有内容都会加载，直到它调用iOS项目的Appdelegate中的ApplicationLoad。所以看起来问题出在表单代码中。
我从设备日志中附加了Stacktrace。如果有人想要缩小问题的范围，那就太好了。
提前致谢。

PS：在android中一切正常。
编辑：添加了FinishedLaunching方法
public override bool FinishedLaunching(UIApplication app, NSDictionary options)
{
Locator.CurrentMutable.RegisterConstant(new IOSCookieStore(), typeof(IPlatformCookieStore));
InitXamarinForms();
Xamarin.FormsMaps.Init();
// check for a notification
if (options != null)
{
// check for a local notification
if (options.ContainsKey(UIApplication.LaunchOptionsLocalNotificationKey))
{
var localNotification = options[UIApplication.LaunchOptionsLocalNotificationKey] as UILocalNotification;
if (localNotification != null)
{
UIAlertController okayAlertController = UIAlertController.Create(localNotification.AlertAction, localNotification.AlertBody, UIAlertControllerStyle.Alert);
okayAlertController.AddAction(UIAlertAction.Create("OK", UIAlertActionStyle.Default, null));
GetWindow().RootViewController.PresentViewController(okayAlertController, true, null);
// reset our badge
UIApplication.SharedApplication.ApplicationIconBadgeNumber = 0;
}
}
}
InitTrackerAndExceptionHandling();
InitAndRegisterPushNotifications();
FFImageLoading.Forms.Touch.CachedImageRenderer.Init();
// Needed for loading the Lib!
var t = typeof(SignaturePad.Forms.iOS.SignaturePadRenderer);
var urls = NSFileManager.DefaultManager.GetUrls(NSSearchPathDirectory.CachesDirectory, NSSearchPathDomain.User);
var path = urls[0].Path;
string pathToCacheDbFile = System.IO.Path.Combine(path, "EasierLife/BlobCache/blobs.db");
LoadApplication(new EasierLifeApp(pathToCacheDbFile));
return base.FinishedLaunching(app, options);
}
我还在考虑使用akavache进行缓存时出错。 但正如我所提到的，实际上我们在这里没有改变任何东西。
编辑2： 好了，我发现，这是akavache /缓存的问题。在不初始化缓存的情况下，应用程序将重新启动。
public void InitCache() {
BlobCache.ApplicationName = "EasierLife";
BlobCache.EnsureInitialized();
_cache = BlobCache.LocalMachine;
}
但我仍然没有回答为什么突然发生这种情况而没有对代码进行任何更改。
