DYCornerBanner

DYCornerBanner written in Swift 3 allows you to quickly create corner labels on top of any kind of view, e.g. UIImageView. The rotation angle of the corner label is determined by the width and height of the banner view.

Features

• set the corner position to bottom right, top right, top left or bottom left.
• supports banners in any rotation angle and distance from the corner - the rotation angle and the distance from the corner are determined by the size and height-width proportion of the DYCornerBanner view's frame.
• override the default setting for the banner label width.
• override the default setting for the banner text font.

Installation

Install DYCornerBanner through Cocoapods or simply clone the repository and drop the DYCornerBanner.swift file into your project. Enter the following information into your Podfile (see current version in header):

platform :ios, '9.0'

use_frameworks!

target '[Your app project title]' do
pod 'DYCornerBanner', '~> 1.0'
end

Make sure to import DYCornerBanner into your View Controller subclass:

	import DYCornerBanner

Usage

See the following examples.

Code example: Creating a DYCornerBanner from Interface Builder

 @IBOutlet weak var cornerBannerBottomLeft: DYCornerBanner!  // simply drop a UIView into the VC from interface builder in storyboard  and set the UIView class to DYCornerBanner
 

 override func viewDidLoad() {
   super.viewDidLoad()
   
   self.cornerBannerBottomLeft.setup(text: "Sunshine Guaranteed!", textColor: 	UIColor.black, bannerColor: UIColor.yellow, position: .bottomLeft)
   
 }

Code example: Creating a DYCornerBanner in code

Alternatively, you can create a corner banner instance in code like so:

   let frame = CGRect(x: self.imageView.frame.size.width -  90, y: 0, width: 90, height: 90)
   let bannerInCode = DYCornerBanner(frame: frame)
   bannerInCode.setup(text: "Free Cocktails!", textColor: UIColor.red, bannerColor: UIColor.white.withAlphaComponent(0.6), position: .topRight)
  self.imageView.addSubview(bannerInCode)

Customising

You can override the settings for bannerWidth and textFont as shown below. Make sure to set these properties before calling setup, otherwise the defaults will be set instead.

  self.cornerBannerTopLeft.textFont = UIFont(name: "ChalkboardSE-Bold" , size: 15.0)!
  self.cornerBannerTopLeft.bannerWidth = 17.0
self.cornerBannerTopLeft.setup(text: "Just Added!", textColor: UIColor.white, bannerColor: UIColor.grassGreen(), position: .topLeft)
