仿餘額寶數字漸慢跳動效果，仿餘額漸慢跳動
找到一個開源Demo：https://github.com/PigRiver/NumberJumpDemo
Demo裡的都是整數間的跳轉，想弄成帶小數的跳轉，很簡單，只要到CATextLayer+NumberJump.m檔案 裡
changeNumberBySelector方法裡修改成如下
float value = [(NSNumber *)[pointValuesobjectAtIndex:1] floatValue];就OK
<html><head><title>js 數字跳動問題</title><script type="text/javascript"> var i = 0; window.onload = function () { setInterval(function () { document.getElementById("myDiv").innerHTML = i++; }, 1000); };</script></head><body> <div id="myDiv"></div></body></html>
電腦開機時出現一排英語，有數字跳動，像更新一樣，數字跳到一百時，螢幕出現未連接線，是為何？
