一款靈動的動畫標簽欄類庫：Ramotion/animated-tab-bar

一款靈動的動畫標簽欄類庫。可在storyboard中直接使用，非常方便。Demo效果非常漂亮。遞交僅一周時間，今天即在GitHub上以122顆星極速躍居到Swift分類第一的位置。

要求

• iOS 7.0+
• Xcode 6.1
</ul>

安裝

Just add the RAMAnimatedTabBarController folder to your project.

用法

1. Create a new UITabBarController in your storyboard or nib.

2. Set the class of the UITabBarController to RAMAnimatedTabBarController in your Storyboard or nib.

3. For each UITabBarItem, set the class to RAMAnimatedTabBarItem.

4. Add a custom image icon for each RAMAnimatedTabBarItem

5. Add animation for each RAMAnimatedTabBarItem :

   • drag and drop an NSObject item into your ViewController
   • set its class to ANIMATION_CLASS (where ANIMATION_CLASS is the class name of the animation you want to use)
   • connect the outlet animation in RAMAnimatedTabBarItem to your ANIMATION_CLASSDemonstration video for step 5

包含的動畫

• RAMBounceAnimation
• RAMLeftRotationAnimation
• RAMRightRotationAnimation
• RAMFlipLeftTransitionItemAniamtions
• RAMFlipRightTransitionItemAniamtions
• RAMFlipTopTransitionItemAniamtions
• RAMFlipBottomTransitionItemAniamtions
• RAMFrameItemAnimation

創建自定義動畫

1. Create a new class which inherits from RAMItemAnimation:

      class NewAnimation : RAMItemAnimation

2. Implement the methods in RAMItemAnimationProtocol:

     // method call when Tab Bar Item is selected
     override func playAnimation(icon : UIImageView, textLable : UILabel) {
       // add animation
     }
   
     // method call when Tab Bar Item is deselected
     override func deselectAnimation(icon : UIImageView, textLable : UILabel, defaultTextColor : UIColor) {
       // add animation
     }
   
     // method call when TabBarController did load
     override func selectedState(icon : UIImageView, textLable : UILabel) {
       // set selected state  
     }

3. Example:

class RAMBounceAnimation : RAMItemAnimation {

    override func playAnimation(icon : UIImageView, textLable : UILabel) {
        playBounceAnimation(icon)
        textLable.textColor = textSelectedColor
    }

    override func deselectAnimation(icon : UIImageView, textLable : UILabel, defaultTextColor : UIColor) {
        textLable.textColor = defaultTextColor
    }

    override func selectedState(icon : UIImageView, textLable : UILabel) {
        textLable.textColor = textSelectedColor
    }

    func playBounceAnimation(icon : UIImageView) {

        let bounceAnimation = CAKeyframeAnimation(keyPath: "transform.scale")
        bounceAnimation.values = [1.0 ,1.4, 0.9, 1.15, 0.95, 1.02, 1.0]
        bounceAnimation.duration = NSTimeInterval(duration)
        bounceAnimation.calculationMode = kCAAnimationCubic

        icon.layer.addAnimation(bounceAnimation, forKey: "bounceAnimation")
    }
}
