Only labels inside of a UIView can be styled

[mcohen75]

I cannot, for example have a label inside of a ScrollView and apply a style to it.

This is due to an explicit check in UILabel+NUI.m at line 25.

if ([self class] == [UILabel class] &&
        [[self superview] class] == [UIView class]) {
        [self initNUI];
        if (![self.nuiClass isEqualToString:@"none"]) {
            [NUIRenderer renderLabel:self withClass:self.nuiClass];
        }
    }

I have worked around this using the following code in my fork,

if ([self class] == [UILabel class] ) {
    if ( ( self.nuiClass && ![self.nuiClass isEqualToString:@"Label"] ) || [[self superview] class] == [UIView class]) {
        [self initNUI];
        if (![self.nuiClass isEqualToString:@"none"]) {
            [NUIRenderer renderLabel:self withClass:self.nuiClass];
        }
    }
}

What it does is only render all labels that are inside UIViews or render the label if they have a custom nuiClass (other than 'Label').

I've just merged @jamesjennings's pull request, which does exactly what @BasitAli mentions for all of the relevant UI elements. Now, if you set the label's nuiClass, styling will be applied. This isn't an ideal long-term solution, but it'll work while we set up support for descendant selectors.

Thanks @BasitAli for the response, and thanks @tombenner for merging that pull request. Looks like a good way to go until descendant selectors are supported.
