UISwitch 子类，当开关打开时，会将其所选颜色“传染”给父视图。灵感来源于这个 Dribble，由Ramotion团队制作。

用法

AMViralSwitch是UISwitch的直接替代品

• 使用AMViralSwitch替代UISwitch
• 设置开关的onTintColor属性

开关将自动将所选颜色传染给其父视图。

动画时长

使用animationDuration属性来控制动画速度

self.toggle.animationDuration = 1.0

动画完成

可以为on和off动画设置完成块

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

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

动画视图

您可以与开关同时动画化其他视图传染。通常，您会想改变同一父视图中视图或标签的颜色。您可以这样做来动画化CoreAnimation属性

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 }
];

要动画化UILabel的textColor属性，语法稍有不同

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] }
];

按照相同的原理来动画化您UIButton的tintColor

Swift

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

Objective-C

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