GravityTagCloudView

A tag cloud view with gravity for iOS. It is a rewritten version of https://github.com/zhangao0086/DKTagCloudView in swift 3 with UIdynamics gravity support (Thanks for this nice tutorial for UI dynamics - https://www.bignerdranch.com/blog/uidynamics-in-swift/).

You may play around GravityTagCloudView on Apptize.

Fill some bugs in the iPhone SE screen:

(To measure the performance of UIDynamic, you may include konoma/fps-counter in your project.)

Playground example:

Play with random font size:

Play with weighted font size and fill the entire view with tags:

How To Get Started

Installation with CocoaPods

Edit your Podfile and add DKTagCloudView, (TODO add to offical pod spec):

pod 'GravityTagCloudView', '~> 0.2.0'

Add import GravityTagCloudView to the top of classes that will use it.

Create instances (Also supports xib/storyboard) :

let gravityTagCloudView = GravityTagCloudView()

gravityTagCloudView.frame = CGRect(x: 0, y: 0, width: 360, height: 200)

self.view.addSubview(gravityTagCloudView)

Setup items:

If you want the size of the label is propertional to their weight, please set labelSizeType properties to kWeighted and assign array to titleWeights:

gravityTagCloudView.labelSizeType = .weighted
gravityTagCloudView.titleWeights = [["title":"elephant", "weight":10],
                                    ["title":"cow", "weight":7],
                                    ["title":"horse", "weight":7],
                                    ["title":"dog", "weight":5],
                                    ["title":"cat", "weight":3],
                                    ["title":"rat", "weight":1],
                                    ["title":"mouse", "weight":1],
                                    ]

Generates:

gravityTagCloudView.generate()

Callback

gravityTagCloudView.tagClickBlock = { title, tag -> Void in       
  print("tag =\(tag), title=\(title)")
}

Customized:

/**

 *  Label size option. Defautls to random.
 */
public var labelSizeType : LabelSizeType = .random

/**
 *  Gravity enabled?
 */
public var isGravity : Bool = true

/**
 *  Min font size. Defautls to 14.
 */
public var minFontSize : Float = 14

/**
 *  Max font size. Defaults to 60.
 */
public var maxFontSize : Float = 60

/**
 *  Random text colors with default list
 */
public var randomColors = [UIColor.black, UIColor.cyan, UIColor.purple, UIColor.orange, UIColor.red, UIColor.yellow, UIColor.lightGray, UIColor.gray, UIColor.green]
