1、功能及简介

  • 1、用分类封装系统的 UIAlertController,代码无侵入,简洁高效,一个block 搞定系统alert 和 actionSheet
  • 2、可以自定义按钮数量、按钮颜色【多按钮样式,颜色数组和title数组个数不等情况下,默认蓝色】【待开发】
  • 3、可以自定义 NSMutableAttributedString 的 alert 和 actionSheet,让你的 alert 更加炫酷【待开发】
  • 4、完美适配 iPhone 和 iPad 版本
  • 5、理论完全兼容现有 iOS 8 以上系统版本

3、安装、导入示例和源码地址

  • 1、pod 导入【最新版本:BAAlertController-Swift】:
    OC: pod 'BAAlertController'
    Swift: pod 'BAAlertController-Swift'

如果发现 pod search BAAlertController-Swift 搜索出来的不是最新版本,需要在终端执行 cd 转换文件路径命令退回到 desktop,然后执行 pod setup 命令更新本地spec缓存(可能需要几分钟),然后再搜索就可以了。
具体步骤:
