Description Tom Gilder 2013-11-26 19:27:07 UTC
UIWindow's WindowLevel property is bound to a float, but should be bound to a corresponding enum (UIWindowLevel.Normal, UIWindowLevel.Alert and UIWindowLevel.StatusBar).

Comment 1 Sebastien Pouliot 2013-11-27 08:19:26 UTC
This is not a mistake. The native/ObjC definition is a `float`, e.g.

    typedef CGFloat UIWindowLevel;

(from your 2nd link) and C# does not allow `enums` to be based on on floats (or doubles).

It's uncommon and it generally means any (float) value is valid and some specific values are given as constants (e.g. you can insert yourwelf between the defined values).

OTOH we should expose enum values as constants (so I'm not closing the bug).
Comment 2 Sebastien Pouliot 2013-11-28 09:29:15 UTC
The next (non-hotfix) release will include a new type that expose the 3 constants.

public static class UIWindowLevel {
	// properties
	public static float Alert { get; }
	public static float Normal { get; }
	public static float StatusBar { get; }
}

So it will be possible to do:

    window.WindowLevel = UIWindowLevel.Alert;

while still allowing any other float values.


Fixed in master d85bf4987d98b9b3101aed798113fb9c2719f8e7
QA: unit tests added in the same revision.

This fix is planned to be released with Xamarin.iOS 7.0.6, which should hit the beta channel before December 23rd.

I verified this issue, following are the verified steps:

1. Created a sample iOS project.
2. opened monotouch assembly and searched "WindowLevel"
3. verified that UIWindowLevel class added with all above mentioned properties.

Checked with:
All Mac
XS 4.2.3 (build 20)
X. iOS 7.0.6.164
