UIColor blendedColorWithForegroundColor Bug with iOS7.1

[ngaje]

FUISwitch and UIColor return "shades of grey" with blendedColorWithForegroundColor in iOS7.1 - ON & OFF Foreground/Background colors return a blend of onWhite and offWhite. This is the section of code that prior to iOS7.1 did not appear to work or not sure of the purpose! Now it does in 7.1 - it returns shades of grey! Any suggestions on a fix for this - other than taking out the if{}'s?

if ([foregroundColor getWhite:&onWhite alpha:nil])
{
onRed = onWhite;
onBlue = onWhite;
onGreen = onWhite;
}
else
{
[foregroundColor getRed:&onRed green:&onGreen blue:&onBlue alpha:nil];
}
if ([backgroundColor getWhite:&offWhite alpha:nil])
{
offRed = offWhite;
offBlue = offWhite;
offGreen = offWhite;
}
else
{
[backgroundColor getRed:&offRed green:&offGreen blue:&offBlue alpha:nil];
}
