BatteryView

Simple battery shaped UIView.

Usage

let batteryView = BatteryView(frame: smallRect)
batteryView.level = 42 // anywhere in 0...100
batteryView.lowThreshold = 25 // battery fill becomes red if level is below this threshold
batteryView.gradientThreshold = 50 // battery fill gradually changes from green to red below this threshold

Changing Appearance

The properties below can be set in Interface Builder, in code, or through a UIAppearance proxy (e.g., BatteryView.appearance().borderColor = .gray).

Colors:

batteryView.borderColor    = .darkGray
batteryView.highLevelColor = .green
batteryView.lowLevelColor  = .red
batteryView.noLevelColor   = .gray
batteryView.noLevelText = "?" // shown over battery when the level is undefined or out of bounds

Battery Shape:

batteryView.direction = .minXEdge     // terminal facing left

batteryView.terminalLengthRatio = 0.1 // relative to battery length
batteryView.terminalWidthRatio = 0.4  // relative to battery width

batteryView.borderWidth = 2.5         // default is batteryLength / 20
batteryView.cornerRadius = 5          // default is batteryLength / 10
