Summary:
In an IBDesignable subclass of UIButton, when calling setImage: programmatically … the image is displayed with the TINT color (both in IB and at runtime).  [This is the tintColor inherited from UIView — even though the image does NOT have its .renderMode property set to Template.]

Workaround:
If the ‘image’ property is set manually in IB, then cleared, the image color returns to normal.  (This might be temporary.)

Sample code, from subclass "CustomButton : UIButton”:

IB_DESIGNABLE
@interface CustomButton ()
@property (nonatomic, strong) IBInspectable NSString *buttonStyle;
@end

-(void)setButtonStyle:(NSString *)styleName {
    if ([styleName isEqualToString:@“play"]) {
        UIImage *foregroundImage = [UIImage imageNamed:(@“icon-play")
                       inBundle:[NSBundle bundleForClass:[self class]]
                compatibleWithTraitCollection:nil];

        [self setImage:foregroundImage forState:UIControlStateNormal];
    }
}

Expected behavior:
The image should show in its true color — just as it does when the same property is set manually in IB [see screenshots].
