iOS 项目集成支付宝SDK的经典错误如下,集成好支付宝SDK后在真机上运行报错： ld: '/Users/wangshuai1/Desktop/aliPaySDKPritical/aliPaySDKPritical/ALiPay/AlipaySDK.framework/AlipaySDK' does not contain bitcode. You must rebuild it with bitcode enab 阅读详情

storyBoard里拖tableView、tableViewCell。记得拖代理

大致思路：注册中心管理设备—》判断蓝牙是否开启——>扫描—》扫描发现设备—》加到数组里，刷新—》点击cell、连接结束扫描—》连接上外设、连接出错、断开连接三个方法。
