作者其他Pod库

播放器 - KJPlayer是一款视频播放器，AVPlayer的封装，继承UIView
pod 'KJPlayer'  # 播放器功能区
pod 'KJPlayer/KJPlayerView'  # 自带展示界面

实用又方便的Category和一些自定义控件
pod 'KJEmitterView'
pod 'KJEmitterView/Function'#
pod 'KJEmitterView/Control' # 自定义控件

轮播图 - 支持缩放 多种pagecontrol 支持继承自定义样式 自带网络加载和缓存
pod 'KJBannerView'  # 轮播图，网络图片加载

菜单控件 - 下拉控件 选择控件
pod 'KJMenuView' # 菜单控件

加载Loading - 多种样式供选择
pod 'KJLoadingAnimation' # 加载控件

Issue

如果您在使用中有好的需求及建议，或者遇到什么bug，欢迎随时issue，我会及时的回复，有空也会不断优化更新这些库

使用方法

将需要转换的json字符串放在坐标框内，转换即可
