大多数用户感知到的卡顿等性能问题的最主要根源都是因为渲染性能。从设计师的角度，他们希望App能够有更多的动画，图片等时尚元素来实现流畅的用户体验。但是Android系统很有可能无法及时完成那些复杂的界面渲染操作。Android系统每隔16ms发出VSYNC信号，触发对UI进行渲染，如果每次渲染都成功，这样就能够达到流畅的画面所需要的60fps，为了能够实现60fps，这意味着程序的大多数操作都必须

python学习list笔记List（列表） 是 Python 中使用最频繁的数据类型；支持字符，数字，字符串甚至可以包含列表（所谓嵌套）1、定义：list = [1,3,4,5,'goog','well',777]2、从最后一列增加： list.append("your are good!")显示：直接输入：list显示：[1, 3, 4, 5, 'goog', 'well', 777

简介 libimobiledevice又称libiphone，是一个开源包，可以让Linux支持连接iPhone/iPod Touch等iOS设备。由于苹果官方并不支持Linux系统，但是Linux上的高手绝对不能忍受因为要连接iOS设备就换用操作系统这个事儿。因此就有人逆向出iOS设备与Windows/Mac Host接口的通讯协议，最终成就了横跨三大桌面平台的非官方版本U
