I got an exception after I went back to home and launched the app and tapped on any alert in iOS 9.x
I do not have any issue with iOS 8.x

'NSInvalidArgumentException', reason: '-[__NSCFNumber title]: unrecognized selector sent to instance 0xb000000000000002'

As per iOS 10b2, the title and message is not visible when using this. Perhaps they rearranged the view hierarchy (again...)?

Is there any ways to set the message colour, when I use the dark mode, the message is also the black colour on ios 9, and it's able to change the button colours but no ways to set the message colour ? and also try every style all the message color is black in alter view.

my codes:
[UIAlertController mz_applyCustomStyleForAlertControllerClass:[UIAlertController class]];
MZAlertControllerStyle *defaultStyle = [UIAlertController mz_sharedStyle];
defaultStyle.blurEffectStyle = UIBlurEffectStyleDark;
defaultStyle.backgroundColor = RF_WHITE_COLOR;
defaultStyle.defaultButtonColor = RF_WHITE_COLOR;
defaultStyle.destructiveButtonColor = RF_WHITE_COLOR;

The background color of UIAlertActionStyleCancel type cannot be modified

MZAlertControllerStyle *defaultStyle = [UIAlertController mz_sharedStyle];
defaultStyle.blurEffectStyle = UIBlurEffectStyleDark;
defaultStyle.backgroundColor = [[UIColor blackColor] colorWithAlphaComponent:0.1];
defaultStyle.actionSheetCancelButtonBackgroundColor = [UIColor redColor];
defaultStyle.shouldApplyBlur = YES;
[defaultStyle setActionSheetCancelButtonConfigurationHandler:^(UIAlertAction *action, UILabel *label, UIView *backgroundView) {
    backgroundView.backgroundColor = [UIColor greenColor];
}];
