8 | 2.强烈建议小图和大图为等比缩放的图片
9 | 3.动画浏览图片，类似微信的效果
10 | 4.长按手势弹框可保存图片，复制图片地址
11 | 5.支持双击和捏合手势放大和缩小图片
12 | 6.支持最低版本iOS7.0 13 | 14 | # 版本2.2 15 | 1.修复加载动画复用圆圈变形问题
16 | 2.修复小图不存在时，大图加载不出来问题 17 | 18 | # 版本2.1 19 | 1.添加浏览本地图片 20 | 21 | # 版本2.0 22 | 1.放弃Autolayout,利用view的transform支持单个浏览页的横屏
23 | 2.双击图片放大缩小添加
24 | 3.长按手势弹框保存图片
25 | 4.部分代码优化 26 | 27 | # 版本1.2 28 | 1.适配iOS7横屏显示错乱的问题
29 | 2.随主流应用，只有浏览图片页才可以横屏
30 | 3.解决加载本地图片第一次会闪一下的bug 31 | 32 | # 版本1.1 33 | 1.添加横竖屏(Masonry布局)
34 | 2.修改了图片加载错乱的bug
35 | 3.View改为ViewController控制
36 | 4.关闭图片浏览view的时候，不需要继续执行小图加载大图动画
37 | 5.修复转换坐标不准确问题 38 | 39 | #Example 40 | 1.加载网络图片
