I have a Xamarin iOS app, it was working properly, but I don't know what I've touched so it started raising this exception when I click on button to move to another view in storyboard:
System.Exception: Failed to marshal the Objective-C object 0x7ffa72c19570 (type: PropertyListViewController). Could not find an existing managed instance for this object, nor was it possible to create a new managed instance (because the type 'Rental.iOS.PropertyListViewController' does not have a constructor that takes one IntPtr argument).

What can I check in Interface Designer to make sure I am not doing anything wrong?
I added thhis constructor:
public partial class PropertyListViewController : UIViewController
{
protected PropertyListViewController(IntPtr handle) : base(handle)
{
// Note: this .ctor should not contain any initialization logic.
}
~~~~
}
But now I receive this error :
Foundation.MonoTouchException: Objective-C exception thrown. Name: NSInternalInconsistencyException Reason: -[UIViewController _loadViewFromNibNamed:bundle:] loaded the "PropertyListViewController" nib but the view outlet was not set.

PropertyListViewController does not have a constructor that takes one IntPtr argument.
In your UIViewController subclass, add an .ctor like so:
public partial class PropertyListViewController : UIViewController
{
protected PropertyListViewController(IntPtr handle) : base(handle)
{
// Note: this .ctor should not contain any initialization logic.
}

does the problem come from webassembly and why?
As #JL0PD correctly guessed in their comment, this is because Bolero's tryfsharp runs an older compiler that doesn't support nameof.
Updating it has been on my to-do list for ever, but there have been non-trivial changes both in Blazor and in the F# compiler service since the latest release of tryfsharp.bolero.
I'm trying to make a Xamarin.Forms Project with speech recognition. For Android done and easy but i'm in the hell with iOS.
I found and i readed about Open Ears.
When tried to use this, i found some problems:
First i try to use this git: https://github.com/oganix/MonoTouch-OpenEars
but monotouch is not valid for Xamarin.iOS:
https://www.dropbox.com/s/41rc7iyskbwby9n/error_phoenix.png?dl=0
Next, i found this question Xamarin OpenEars Native Binding Not working on Device but works on Simulator.
After read, i tried to make a binding proyect and now i have this issue when use sharpie for autogenerate the Open Ears API:
/Users/cristian.fernandez/Workspace/Speech-iOS/OpenEarsDistribution/Framework/OpenEars.framework/Versions/A/Headers/acmod.h:50:10: fatal error: 'sphinxbase/cmd_ln.h' file not found

What can i do now besides cry?
Thanks for all and sorry for my English.
Not sure why my code isn't working as I've followed examples I've found. Trying to get my iOS game to save and load data back using Unity3D but not using the player.prefs.
On the scene's I have this
void OnDisable(){
GameController.Save ();
}
void OnEable(){
GameController.Load ();
}
Game Controller is a static method..
static public void Save()
{
Debug.Log("Saving Player Data...");
print ("Saving Player Data...");
var bf = new BinaryFormatter();
var file = File.Create(Application.persistentDataPath + "/CatEscapeInfo.dat");
var data = new PlayerData
{
PlayerLives = PlayerLives,
Score = Score,
Distance = Distance,
CurrentLevelNo = CurrentLevelNo,
HighestLevelCompleted = HighestLevelCompleted
};
bf.Serialize(file, data);
file.Close();
//PlayerPrefs.SetString (data);
Debug.Log ("Player Data Saved: " + PlayerLives + ", " + Score);
print ("Player Data Saved: " + PlayerLives + ", " + Score);
}
static public void Load()
{
Debug.Log("Loading Player Data...");
if (File.Exists(Application.persistentDataPath + "/CatEscapeInfo.dat"))
{
var bf = new BinaryFormatter();
var file = File.Open(Application.persistentDataPath + "/CatEscapeInfo.dat", FileMode.Open);
var data = bf.Deserialize(file) as PlayerData;
file.Close();
Debug.Log("Player Data Loaded: " + data.PlayerLives + ", " + data.Score);
print ("Player Data Loaded: " + data.PlayerLives + ", " + data.Score);
if (data != null)
{
PlayerLives = data.PlayerLives;
Score = data.Score;
Distance = data.Distance;
CurrentLevelNo = data.CurrentLevelNo;
HighestLevelCompleted = data.HighestLevelCompleted;
}
}
}
Even though I have this code running, when I manually close the game on iOS and bring it back up it never loads the game back to the stats it had.
Any thoughts? Am I missing something?
Update:
In iOS XCode, I find it's spitting out this stack trace when trying to "Load" though at the this point the file doesn't exist yet.
On Loading This is Stack Trace:

Put this code to Awake or Start funtion in your scene script:
// Forces a different code path in the BinaryFormatter that doesn't rely on run-time code generation (which would break on iOS).
Environment.SetEnvironmentVariable("MONO_REFLECTION_SERIALIZER", "yes");
By default Mono binary-serializer uses JIT-compilation which is unsupported by iOS. Fortunately, there is a way (the code above) to switch it to use reflection instead.

http://answers.unity3d.com/questions/30930/why-did-my-binaryserialzer-stop-working.html
Environment.SetEnvironmentVariable("MONO_REFLECTION_SERIALIZER", "yes");
Create an error in the Unity editor like:
"Environment" not found in namespace
After hours of searching I found the following code that works perfectly:
System.Environment.SetEnvironmentVariable("MONO_REFLECTION_SERIALIZER","yes");
I hope it'll help.
My iOS Simulator crashes when I try to use a UITapGestureRecognizer.
This is my Gesture:
UITapGestureRecognizer tap = new UITapGestureRecognizer (new NSAction(delegate {
if(SettingsTapped != null){
SettingsTapped(this, EventArgs.Empty);
}
}));
I am adding this Gesture to a UIView and then add this view to a UITableViewCell.
The App crashes after touching the View (every time), showing no Exception.
Her is a Output from the Simulator Log File:

What can I do now?
I don´t want to Develop on the Device...
EDIT
I ended up by overriding UIView and use its TouchesBegan() Method.
There are many approaches to make something clickable but why can´t I just use this one above??
Here's a bit of code that I'm using in my application:
private void addTapGesture()
{
imgLogo.UserInteractionEnabled = true;
var tapGesture = new UITapGestureRecognizer(this, new Selector("ResendTrigger:"));
tapGesture.NumberOfTapsRequired = 5;
imgLogo.AddGestureRecognizer(tapGesture);
}
[Export("ResendTrigger:")]
public void ResendTrigger(UIGestureRecognizer sender)
{
System.Diagnostics.Debug.WriteLine("Triggered");}
}
First argument of constructor (this) points to object that contains definition of method with specified Export attribute so if you will define selector and method inside your view NSObject target will be reference of your view if method that you want to call exist for example in cell your cell reference will be the target.EDITBased on comment I assumed that you may be using UITableViewSource . I think your case is similar to mine so try this approach :Declare event in your UITableSource something like public event EventHandler<DataBaseModels.SavedActions> OnActionSelected;Then in getCell assign tap gesture to your view and inside method you will have reference to sender objec, cast it to UIView and retain tag to identify corresponding record
I am getting this error when trying to create a new View in an ASP.Net MVC 4 project in Xamarin Studio. There are no pending updates in my setup. How can I fix this?
