Like button animation similar to Zhihu

Source code introduction:

NumberScrollAnimatedView.swift This file encapsulates the animation effect similar to the counter and can be used separately.

The ZanButton.swift file encapsulates the entire like animation process. Just find a UIView and set it to this class.

For details, please see the project's comments and examples.

PS PopView with arrows has not been implemented yet, it should not be difficult. I will continue to improve it next time

Source code effect:

Source code snippet:

 <br>
 <br>
 /**<br>
 * Set the like action<br>
 */ <br>
        zanView.zanAction = {(zhanNumber)->Void in<br>
            self.label.text = "(zhanNumber)" <br>
            self.label.textColor = UIColor(red: 0.098 , green: 0.565 , blue: 0.827 , alpha: 1 )<br>
 }<br>
 <br>
 /**<br>
 * Set the action to cancel the like<br>
 */ <br>
        zanView.unzanAction = {(zhanNumber)->Void in<br>
            self.label.text = "(zhanNumber)" <br>
            self.label.textColor = UIColor.blackColor()<br>
 }<br>
 <br>
 //Set the initial value<br>  
        zanView.initNumber = 5 <br>
 <br>
