Build Status

UISwitch subclass that 'infects' the parent view with the onTintColor when the switch is turned on. Inspired by this Dribble by Ramotion.

Installation

Usage

AMViralSwitch is a drop-in replacement of UISwitch:

  • Use AMViralSwitch instead of UISwitch
  • Set the onTintColor property of the switch

The switch will automatically infect its superview with the selected color.

Animation duration

Use animationDuration property to control the animation's speed:

self.toggle.animationDuration = 1.0

Animation completion

You can set a completion block for both on and off animations:

self.toggle.completionOn = {
  print("Enabled")
}

self.toggle.completionOff = {
  print("Disabled")
}

Animate views

You can animate other views alongside the switch infection. Typically you'll want to change color to views or labels that are inside the same superview. You can animate CoreAnimation properties likes this:

Swift

toggle.animationElementsOn = [
    [
        AMElementView: self.greenView.layer,
        AMElementKeyPath: "backgroundColor",
        AMElementFromValue: UIColor.blackColor().CGColor,
        AMElementToValue: UIColor.whiteColor().CGColor
    ]
]

Objective-C

self.toggle.animationElementsOn = @[
   @[ AMElementView: self.greenView.layer,
      AMElementKeyPath: @"backgroundColor", 
      AMElementFromValue: (id)[UIColor clearColor].CGColor,
      AMElementToValue: (id)[UIColor whiteColor].CGColor }
];

To animate the textColor of an UILabel the syntax is slightly different:

Swift

toggle.animationElementsOn = [
    [
        AMElementView: label,
        AMElementKeyPath: "textColor",
        AMElementFromValue: UIColor.blackColor(),
        AMElementToValue: UIColor.whiteColor()
    ]
]

Objective-C

self.blueSwitch.animationElementsOn = @[
    @{ AMElementView: self.blueLabel,
       AMElementKeyPath: @"textColor",
       AMElementToValue: [UIColor whiteColor] }
];

Follow the same principle to animate the tintColor of your UIButtons:

Swift

toggle.animationElementsOn = [
    [
        AMElementView: self.infoButton,
        AMElementKeyPath: "tintColor",
        AMElementToValue: UIColor.whiteColor()
    ]
]

Objective-C

self.blueSwitch.animationElementsOn = @[
    @{ AMElementView: self.infoButton,
       AMElementKeyPath: @"tintColor",
       AMElementToValue: [UIColor whiteColor] }
];
