After I updated to XF 2.3.4-pre5
XF/iOS's Global Tint color does not effect to DisplayAlert nor DisplayActionSheet.
So, my text color of DisplayAlert and DisplayActionSheet is set as blue color (which is default tint color).
It worked fine on XF220.127.116.11 with same Xamarin.iOS version which is latest.(Version: 10.4.0.123)
below code is my code that changes global tint color in AppDelegate.cs
LoadApplication (new App ());
bool result = base.FinishedLaunching(app, options);
UIApplication.SharedApplication.KeyWindow.TintColor = AppConstants.GlobalColor.ToUIColor();
Below code does not work either.
UIAlertView.Appearance.TintColor = mycolor;
UIActionSheet.Appearance.TintColor = mycolor;
attached sample project reproduces this bug.
I was able to reproduce this issue with the attached repro project and Forms 2.3.4-pre5. It is ignoring the UIApplication.SharedApplication.KeyWindow.TintColor set in AppDelegate and using the default color instead.
This does appear to be a regression as the issue does not occur with Forms 18.104.22.168.
### Regression Status
Forms 2.3.4-pre5 BAD
Forms 22.214.171.124 GOOD
Btw setting KeyWindow doesn't seem the correct way, maybe try UIWindow.Appearence.TintColor
In order to address some other problems in alerts and action sheets, DisplayAlert and DisplayActionSheet no longer use UIAlertView and UIActionSheet (both of which are deprecated as of iOS 8); instead they now use UIAlertController. They also display in a new UIWindow, which means they do not inherit the main application window's settings.
For globally setting a tint color which also applies to alerts and action sheets, you can use something like:
`UIView.Appearance.TintColor = myColor;`
If you only want to set the colors for alerts and action sheets specifically, you can use the `AppearanceWhenContainedIn` method, something like this:
`UIView.AppearanceWhenContainedIn(typeof(UIAlertController)).TintColor = UIColor.Green;`
Hi E.Z. Hart.
but UIView.Appearance.TintColor = AppConstants.GlobalColor.ToUIColor(); is unusable because if I do that, it changes UITabbar's unseleced color as well, which is not correct behavior.
I changed each UI type separately. like below.
UITabBar.Appearance.TintColor = AppConstants.GlobalColor.ToUIColor();
UITextField.Appearance.TintColor = AppConstants.GlobalColor.ToUIColor();
UIView.AppearanceWhenContainedIn(typeof(UIAlertController)).TintColor = AppConstants.GlobalColor.ToUIColor();
It's working well so far.
