MvvmCross: Binding progress bar in iOS - ios

Question

I would like to know how to bind the UIProgressView's Progress property.
Having this in the design:
[Outlet]
MonoTouch.UIKit.UIProgressView ProgressIndicator { get; set; }
I've tried the following:
set.Bind(ProgressIndicator).For(p => p.Progress).To(vm => vm.IosProgress);
set.Bind(ProgressIndicator).For("Progress").To(vm => vm.IosProgress);
In the ViewModel I have:
private float _iosProgress;
public float IosProgress
{
get { return _iosProgress; }
set { _iosProgress = value; RaisePropertyChanged(()=>IosProgress); }
}
UPDATE AS REQUESTED:
- I have an iPhone 4 with iOS7.
- I have tried to bind the IosProgress indicator to a Label, works perfectly, having tested with 3 values, 0.33333, 0,666667 and 1 showing in the label.
I created two screen captures for you.
This is showing the value of the IosProgress indicator during debug with initial value given in constructor as 0.1f, also the debug message.
This is showing the 3 versions I've tried, having the same faulty results, debug message for the current one:
Thank you!

I just tried the SeekView in https://github.com/MvvmCross/MvvmCross-Tutorials/tree/master/ApiExamples with a UIProgressView like:
public override void ViewDidLoad()
{
base.ViewDidLoad();
var label = new UILabel(new RectangleF(10, 100, 100, 30));
label.Text = "Slide me:";
Add(label);
var seek = new UISlider(new RectangleF(110, 100, 200, 30));
seek.MinValue = 0;
seek.MaxValue = 100;
Add(seek);
var pro = new UIProgressView(new RectangleF(110, 130, 200, 30));
Add(pro);
var set = this.CreateBindingSet<SeekView, SeekViewModel>();
set.Bind(seek).To(vm => vm.SeekProperty);
set.Bind(pro).For(v => v.Progress).To("SeekProperty / 100");
set.Apply();
}
This worked exactly as expected on an iOS7 iPhone simulator.
The only problem I had was if the ViewModel property went outside the 0.0f to 1.0f range.
