iOS swift 设置电量 计算属性实例

// width: 21
@IBOutlet var batteryBackView: UIView!
@IBOutlet var btteryContentView: UIView!
@IBOutlet var batteryTrailingConstraint: NSLayoutConstraint!
var batteryValue: CGFloat = 0 {
willSet {
batteryTrailingConstraint.constant = 19 - newValue/100*18
if newValue <= 10 { btteryContentView.backgroundColor = .hexColor(hexValue: 0xFA3C3C)
