Uilabel Subclass Appearance in Storyboard

UILabel subclass appearance in Storyboard

You could make it @IBDesignable, and then implement prepareForInterfaceBuilder:

@IBDesignable
public class MyUILabel: UILabel {

    public override func awakeFromNib() {
        super.awakeFromNib()
        configureLabel()
    }

    public override func prepareForInterfaceBuilder() {
        super.prepareForInterfaceBuilder()
        configureLabel()
    }

    func configureLabel() {
        font = UIFont(name: Constants.DefaultFont, size: 40)
    }

}

Note, IB didn't like it when I implemented init(coder:), so I moved it into awakeFromNib.

Also note that when you make an @IBDesignable class, Apple advises that you create a separate target (e.g. "File" - "New" - "Target..." - "Cocoa Touch Framework") for this designable class. For more information, see WWDC 2014 video What’s New in Interface Builder.

Standard text colour by subclassing UILabel for use on a storyboard - (IBOutlet)

That's because in init method no UI objects aren't initialised yet. You need to do it in awakeFromNib method.

-(void)awakeFromNib {
    [super awakeFromNib];
    [self setTextColor:kColourDefaultAppColourText];
}

Or you can use appearance. Set it in eg. didFinishLaunchingWithOptions method with your subclass:

[[CHLabel appearance] setTextColor:kColourDefaultAppColourText];

What is the white area around the UILabel when it is selected in storyboard?

It's just the Xcode UI behaviour of Xcode's interface builder, which highlights the selected UI component. It's not just for UILabel, every UI component has this effect.

UIAppearance overwrites custom textColor on UILabel

What you're experiencing is simply a matter of the exact timing with which the UIAppearance proxy applies its settings to a new UIView. When are we to suppose it does this? It can't possibly do it before init, because init is the first thing that happens in the life of the UIView. Thus, the order of events is like this:

override init(frame: CGRect) {
    super.init(frame: frame)
    setup() // black
}
// and some time later, UIAppearance proxy comes along and sets it to white

So your goal is to call setup pretty early in the life of the label — and certainly before the user ever has a chance to see it — but not so early that the UIAppearance proxy acts later. Let's move the call to setup to a bit later in the life of the label:

// some time earlier, UIAppearance proxy sets it to white
override func didMoveToSuperview() {
    setup() // black
}

Now we're acting after the appearance proxy has had a chance to act, and so your settings are the last to operate, and they win the day.

We remain in ignorance of how early we could move the call to setup and still come along after the appearance proxy setting has been obeyed. If you have time, you might like to experiment with that. For example, willMoveToSuperview is earlier; if you call setup there (and not in didMoveToSuperview), does that work? Play around and find out!

UILabel with text of different color in Storyboard

To achieve that in storyboard, make the label's text attributed, then select the range and change colors accordingly.

See the image below:

Hope this helps.

UILabel subclass - text cut off in bottom despite label being correct height

Turns out the problem was with

self.lineBreakMode = .ByClipping

changing it to

self.lineBreakMode = .ByCharWrapping

Solved the problem

Custom UILabel not displaying properly in Interface Builder

I think you need to call this:

[super drawRect:rect];

iPhone iOS UILabel how to customize text color for UITableView detail text labels only?

You could trick around this by subclassing the cells in the detail view, then use

[[UILabel appearanceWhenContainedIn:[YOUR_UITableViewCell class], nil] 
 setTextColor:[UIColor other_colr]];
