Usage

Start

First, import JLStickerTextView, then subclass the UIImageView, which you want to add text on, to JLStickerImageView, like this:

import JLStickerTextView
class ViewController: UIViewController {
    @IBOutlet var stickerView: JLStickerImageView!
}

If you use Storyboard, you also need connect the UIImageView to JLStikcerImageView Class in Identity Inspector.

Add new Label

It is quite easy to add new label to current StickerImageView:

stickerView.addLabel()

Set the Label

You can set the color, font , alignment, alpha.... of the label.(check all avaliable text attributes)

stickerView.textColor = UIColor.whiteColor()

Note: when you set the properties, you make change to the current selected TextLabel.

Render Text on Image

When you feel good, you are going to render the Text on Image and save the image:

let image = stickerView.renderTextOnView(stickerView)
UIImageWriteToSavedPhotosAlbum(image!, nil, nil, nil)

Customize the StickerTextView appearance

Customize stickerTextView appearance is very strightforward:

//Set the image of close Button
stickerView.currentlyEditingLabel.closeView!.image = UIImage(named: "cancel")
//Set the image of rotate Button
stickerView.currentlyEditingLabel.rotateView?.image = UIImage(named: "rotate")
//Set the border color of textLabel
stickerView.currentlyEditingLabel.border?.strokeColor = UIColor.redColor().CGColor

Note: closeView and rotateView are both UIimageView, while border is CAShapeLayer

Scale stickerView proportionally

This function is not complete yet, I just make it to fit my requirement.

stickerView.limitImageViewToSuperView()

When you render the text on UIImageView whose content mode is AspectFit, it is possible you will get some unwanted border. This function will scale UIImageView to fit the image.

Plan

Here are some ideas:

• [ ] More options for text(eg: lineSpacing)
• [x] Interface to customize the appearance of StickerLabelView(close Button, rotate button, border,etc)
• [ ] More general solution for Scaling stickerView proportionally
• [ ] Support placeholder
