Getting Started

import TextDrawer
Design

This framework is composed on different parts. The first one is the TextEditView. It allows you to edit the text. it is composed of a UITextView, and manage the keyboard notifications. Next, DrawTextView, is a UIView, showing your text in the view. And, TextDrawer, it contains the above views. It allows to configure some parameter (like font, size, color, etc ...). All the gestures are managed here.

Usage

Add an instance of TextDrawer above an UIImageView, or an another UIView (with an optional clear background). Adjust the size and layout of TextDrawer however you'd like. TextDrawer uses, Masonry to manage auto-layout. You don't have anything to do, after that. TextDrawer will handle, the gesture for you. See this screen bellow.

Render the TextDrawer to an UIImage outup:

// draw the TextDrawer view on an UIImageView
let image = drawTextView.renderTextOnView(imageViewBackground)

// render the TextDrawer View to UIImage
let image = drawTextView.render()

// render the TextDrawer View directly on an UIImage
let image = drawTextView.renderTextOnImage(image)

Clear the TextDrawer view:

self.textDrawer.clearText()
self.textDrawer.resetTransformation()

TextDrawer configuration:

drawTextView.font = UIFont.systemFontOfSize(34)
drawTextView.textColor = UIColor.whiteColor()
drawTextView.textAlignement = NSTextAlignment.Center
drawTextView.textBackgroundColor = UIColor.redColor()
drawTextView.text = "test input"
drawTextView.textSize = 40
