I have a UILabel and I want to change its background view. Somebody advised me to use bezier but I want a simple variant.

My label:

What it should look like:

Answer 1

Since these are not very complex shapes, I would suggest creating two white UIViews, rotating them 45 degrees and then adding them as subviews to the UILabel. The code would look something like this:

    myLabel.clipsToBounds = true
    // create the triangle on the left side of the label
    let leftSquare = UIView(frame: CGRect(x: myLabel.frame.height / -2, y: 0, width: myLabel.frame.height, height: myLabel.frame.height))
    leftSquare.translatesAutoresizingMaskIntoConstraints = true
    leftSquare.isUserInteractionEnabled = false
    leftSquare.backgroundColor = UIColor.white
    leftSquare.transform = CGAffineTransform(rotationAngle: CGFloat(Double.pi / 4)) // 45 degree rotation
    // create the triangle on the right side of the cell
    let rightSquare = UIView(frame: CGRect(x: myLabel.bounds.width - (myLabel.frame.height / 2), y: 0, width: myLabel.frame.height, height: myLabel.frame.height))
    rightSquare.translatesAutoresizingMaskIntoConstraints = true
    rightSquare.isUserInteractionEnabled = false
    rightSquare.backgroundColor = UIColor.white
    rightSquare.transform = CGAffineTransform(rotationAngle: CGFloat(Double.pi / 4))
    // add squares to label
    myLabel.addSubview(leftSquare)
    myLabel.addSubview(rightSquare)
    myLabel.sendSubview(toBack: leftSquare)
    myLabel.sendSubview(toBack: rightSquare)
