自定义地物未显示在“今日扩展"中 [英] Custom figure doesn't display in Today Extension
本文介绍了自定义地物未显示在“今日扩展"中的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我在今天的扩展中取得进展.我为此创建了其他类.我可以在IBDesignable
的帮助下在情节提要中看到它.但是,圆圈并没有出现在实际设备(iPhone 5s,iPad 3)或模拟器上的今天扩展中.我该如何解决?
I make progress circle in today extension. I create additional class for it. I can see it in storyboard with help of IBDesignable
. But circle doesn't appear in today extension on real device ( iPhone 5s, iPad 3) or simulator. How can I fix it?
import UIKit
@IBDesignable
class CPUView: UIView {
// MARK: - colors
@IBInspectable var firstColor: UIColor = UIColor.blackColor()
@IBInspectable var secondColor: UIColor = UIColor.greenColor()
@IBInspectable var thirdColor: UIColor = UIColor.yellowColor()
// Only override drawRect: if you perform custom drawing.
// An empty implementation adversely affects performance during animation.
override func drawRect(rect: CGRect) {
// Drawing code
self.addCircle(10, capRadius: 0.0)
}
func addOval(lineWidth: CGFloat, path: CGPath, strokeColor: UIColor, fillColor: UIColor, strokeStart: CGFloat, strokeEnd: CGFloat) {
let shape = CAShapeLayer()
shape.lineWidth = lineWidth
shape.path = path
shape.strokeColor = strokeColor.CGColor
shape.fillColor = fillColor.CGColor
shape.strokeStart = strokeStart
shape.strokeEnd = strokeEnd
layer.addSublayer(shape)
}
func addCircle(arcRadius: CGFloat, capRadius: CGFloat) {
let X = CGRectGetMidX(self.bounds)
let Y = CGRectGetMidY(self.bounds)
let firstPathCircle = UIBezierPath(ovalInRect: CGRectMake(X - arcRadius/2, Y - arcRadius/2, arcRadius, arcRadius)).CGPath
self.addOval(0.1, path: firstPathCircle, strokeColor: UIColor.redColor(), fillColor: UIColor.yellowColor(), strokeStart: 0.0, strokeEnd: 0.5)
}
}
更新
我试图用drawRect
编写代码,但是得到了相同的结果
I tried to write the code in drawRect
but I got the same result
override func drawRect(rect: CGRect) {
// Drawing code
let x = CGRectGetMidX(self.bounds)
let y = CGRectGetMidY(self.bounds)
let radius = CGFloat()
let path = UIBezierPath(ovalInRect: CGRectMake(x - radius/2, y - radius, 100, 100)).CGPath
let shape = CAShapeLayer()
shape.lineWidth = 0.0
shape.fillColor = UIColor.greenColor().CGColor
shape.path = path
layer.addSublayer(shape)
}
推荐答案
我写了以下代码,它对我有用
I wrote the following code and it works for me
override func viewDidLoad() {
super.viewDidLoad()
self.preferredContentSize = CGSize(width: self.view.frame.width, height: 200.0)
}
