篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Swift - 添加UIView后无法点击按钮相关的知识,希望对你有一定的参考价值。
所以,我有一个类创建了UIView
的Confetti子类,它在达到高分时运行。但是,当五彩纸屑运行时,我的按钮变得不可点击,这使它成为问题。当没有运行五彩纸屑时,我的按钮是可点击的,没有错误。请帮助我,我一直试图解决这个问题几个小时。
这是我运行Confetti的代码:
override func viewDidLoad() {
super.viewDidLoad()
if UserDefaults.standard.integer(forKey: "Score") > UserDefaults.standard.integer(forKey: "Highscore") {
confettiView.startConfetti()
delay(3, completion: {
confettiView.stopConfetti()
})
}
这是我创建五彩纸屑的代码:
import UIKit
import QuartzCore
public class SAConfettiView: UIView {
public enum ConfettiType {
case Confetti
case Triangle
case Star
case Diamond
case Image(UIImage)
}
var emitter: CAEmitterLayer!
public var colors: [UIColor]!
public var intensity: Float!
public var type: ConfettiType!
private var active :Bool!
required public init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
setup()
}
public override init(frame: CGRect) {
super.init(frame: frame)
setup()
}
func setup() {
colors = [UIColor(red:0.95, green:0.40, blue:0.27, alpha:1.0),
UIColor(red:1.00, green:0.78, blue:0.36, alpha:1.0),
UIColor(red:0.48, green:0.78, blue:0.64, alpha:1.0),
UIColor(red:0.30, green:0.76, blue:0.85, alpha:1.0),
UIColor(red:0.58, green:0.39, blue:0.55, alpha:1.0)]
intensity = 0.5
type = .Confetti
active = false
}
public func startConfetti() {
emitter = CAEmitterLayer()
emitter.emitterPosition = CGPoint(x: frame.size.width / 2.0, y: 0)
emitter.emitterShape = kCAEmitterLayerLine
emitter.emitterSize = CGSize(width: frame.size.width, height: 1)
var cells = [CAEmitterCell]()
for color in colors {
cells.append(confettiWithColor(color: color))
}
emitter.emitterCells = cells
layer.addSublayer(emitter)
active = true
}
public func stopConfetti() {
emitter?.birthRate = 0
active = false
}
func imageForType(type: ConfettiType) -> UIImage? {
var fileName: String!
switch type {
case .Confetti:
fileName = "confetti"
case .Triangle:
fileName = "triangle"
case .Star:
fileName = "star"
case .Diamond:
fileName = "diamond"
case let .Image(customImage):
return customImage
}
/*
let path = Bundle(for: SAConfettiView.self).path(forResource: "SAConfettiView", ofType: "bundle")
let bundle = Bundle(path: path!)
let imagePath = bundle?.path(forResource: fileName, ofType: "png")
let url = NSURL(fileURLWithPath: imagePath!)
let data = NSData(contentsOf: url as URL)
if let data = data {
return UIImage(data: data as Data)!
}
return nil */
return UIImage(named: fileName)
}
func confettiWithColor(color: UIColor) -> CAEmitterCell {
let confetti = CAEmitterCell()
confetti.birthRate = 6.0 * intensity
confetti.lifetime = 14.0 * intensity
confetti.lifetimeRange = 0
confetti.color = color.cgColor
confetti.velocity = CGFloat(350.0 * intensity)
confetti.velocityRange = CGFloat(80.0 * intensity)
confetti.emissionLongitude = CGFloat(M_PI)
confetti.emissionRange = CGFloat(M_PI_4)
confetti.spin = CGFloat(3.5 * intensity)
confetti.spinRange = CGFloat(4.0 * intensity)
confetti.scaleRange = CGFloat(intensity)
confetti.scaleSpeed = CGFloat(-0.1 * intensity)
confetti.contents = imageForType(type: type)!.cgImage
return confetti
}
public func isActive() -> Bool {
return self.active
}
}
答案
开始运行五彩纸屑后,将按钮子视图置于正面。
希望这可以帮助。
另一答案
看来你的新视图模糊了它下面的按钮视图。理想情况下,在完成所有操作后,您应该从stopConfetti()方法中的superview中删除五彩纸屑视图。
