你如何在一个屏幕上有两个随机字生成器

我目前正在开发一个应用程序，在这个应用程序中，您可以分别将电话屏幕的两半分别滑动，而每次向左滑动时都会生成一个随机单词。

我已经为屏幕的上半部分创build了一个随机生成单词的单词列表。 我将如何应用这种相同的方法在屏幕的下半部分？ 我有2个图像的代码，我目前在视图控制器

import UIKit class ViewController: UIViewController { // put the labels and the buttons @IBOutlet var InspirationalThought: UILabel! @IBOutlet var Click: UIButton! //what the label is going to show var quotes = ["Geometrics", "Vectors", "Celebration", "Triangle", "Landscapes", "Seasons", "Snow", "Rain", "Sunrays", "Stencils", "Paint", "Graphics", "Graffiti", "Sports","Fashion","Ancient Greek", "Philosophers", "Fairy tales", "Fantasy", "Clouds", "Mystery", "Time Clocks", "Canvas", "Tie-dye", "Glitter", "Dessert", "Desert", "Energy", "Astrology", "Solar Systems", "Sea", "Beach", "Sphere", "Roots", "Lights", "Darks", "Fire", "Air", "Aperture", "Long exposure", "Portraits", "World", "Travel", "Architecture", "Freedom", "Old", "New", "Urban", "Lenses", "Fisheye", "Chords", "Music notes", "Spices", "Herbs", "Natural", "Marbles", "Wood", "Trees", "Forests", "Interior","Mammals", "Reptiles", "Ocean", "Birds", "Photography", "Exposure", "Opaque", "Translucent", "Freestyle", "Spots", "Stripes", "Zig Zag", "Spiral", "Glass", "Feathers", "Calm", "Bulb", "Heat", "Cold", "Stitches", "Views", "Birds", "Sunset", "Earth"] var whichQuotestoChoose = 0 // what the button is going to show var ButtonText = ["Inspiration", "Tell me more", "more inspirational"] var whichButtonTexttoChoose = 0 @IBAction func ClickButtonClicked(sender: UIButton) { chooseAQuote() chooseTextonButton() } func chooseAQuote(){ showTheQuote() whichQuotestoChoose = Int(arc4random_uniform (84)) } func showTheQuote(){ InspirationalThought.text = "\(quotes[whichQuotestoChoose])" } func chooseTextonButton(){ Click.setTitle("\(ButtonText[whichButtonTexttoChoose])", forState:UIControlState.Normal) } } 

Answer 1

这是你如何做到的。 如果您的背景保持不变，顶部和底部的颜色总是与星星相同，然后将其作为图像。

添加imageView并将图像设置为背景图像

添加2个UIView的view1和view2作为顶部和底部视图。 设置背景颜色为clearColor，标签分别为1和2

使用相同的select器添加滑动手势2。

将UILabel添加到每个视图label1和label2。

创build一个string来保存来自引号的文本当被转移。 根据视图的标签，相应地设置标签文本。

以下是示例实现：

 import UIKit class ViewController: UIViewController { @IBOutlet weak var view1: UIView! @IBOutlet weak var view2: UIView! @IBOutlet weak var label1: UILabel! @IBOutlet weak var label2: UILabel! var displayString: String? var quotes = ["Geometrics", "Vectors", "Celebration", "Triangle", "Landscapes", "Seasons", "Snow", "Rain", "Sunrays", "Stencils", "Paint", "Graphics", "Graffiti", "Sports","Fashion","Ancient Greek", "Philosophers", "Fairy tales", "Fantasy", "Clouds", "Mystery", "Time Clocks", "Canvas", "Tie-dye", "Glitter", "Dessert", "Desert", "Energy", "Astrology", "Solar Systems", "Sea", "Beach", "Sphere", "Roots", "Lights", "Darks", "Fire", "Air", "Aperture", "Long exposure", "Portraits", "World", "Travel", "Architecture", "Freedom", "Old", "New", "Urban", "Lenses", "Fisheye", "Chords", "Music notes", "Spices", "Herbs", "Natural", "Marbles", "Wood", "Trees", "Forests", "Interior","Mammals", "Reptiles", "Ocean", "Birds", "Photography", "Exposure", "Opaque", "Translucent", "Freestyle", "Spots", "Stripes", "Zig Zag", "Spiral", "Glass", "Feathers", "Calm", "Bulb", "Heat", "Cold", "Stitches", "Views", "Birds", "Sunset", "Earth"] var whichQuotestoChoose = 0 override func viewDidLoad() { super.viewDidLoad() // Do any additional setup after loading the view, typically from a nib. let swipeLeft = UISwipeGestureRecognizer(target: self, action: #selector(ViewController.viewSwipped(_:))) swipeLeft.direction = UISwipeGestureRecognizerDirection.Left view1.addGestureRecognizer(swipeLeft) let swipeLeft1 = UISwipeGestureRecognizer(target: self, action: #selector(ViewController.viewSwipped(_:))) swipeLeft1.direction = UISwipeGestureRecognizerDirection.Left view2.addGestureRecognizer(swipeLeft1) } func viewSwipped(gesture: UIGestureRecognizer) { self.chooseAQuote() if let swippedView = gesture.view { if swippedView.tag == 1 { label1.leftToRightAnimation() label1.text = displayString } else { label2.leftToRightAnimation() label2.text = displayString } } } func chooseAQuote() { displayString = quotes[whichQuotestoChoose] whichQuotestoChoose = Int(arc4random_uniform (84)) } override func didReceiveMemoryWarning() { super.didReceiveMemoryWarning() // Dispose of any resources that can be recreated. } } extension UIView { func leftToRightAnimation(duration: NSTimeInterval = 0.5, completionDelegate: AnyObject? = nil) { // Create a CATransition object let leftToRightTransition = CATransition() // Set its callback delegate to the completionDelegate that was provided if let delegate: AnyObject = completionDelegate { leftToRightTransition.delegate = delegate } leftToRightTransition.type = kCATransitionPush leftToRightTransition.subtype = kCATransitionFromRight leftToRightTransition.duration = duration leftToRightTransition.timingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut) leftToRightTransition.fillMode = kCAFillModeRemoved // Add the animation to the View's layer self.layer.addAnimation(leftToRightTransition, forKey: "leftToRightTransition") } }
