ios开发中有没有一种技术能在二维码中间嵌套一个二维码让相机能够识别区分这两个二维码呢
可以实现的，二维码包含的信息是由你控制的，对这两个二维码做不同标示，扫描时根据这个标示做个判断就可以实现
在apicloud开发app的时候，ios企业级证书，二维码扫描无法正常安装？
原因是制作mobileprovision证书时，没有选择in house而是选择了 ad hoc, ad hoc只支持证书绑定的测试设备,inhouse是不限制设备的，任何Ios设备都可以直接安装app,另外替换了证书记得在云端点击“保存”，不保存还是老的证书。
iOS做扫描二维码界面，有什么第三方框架可以用

iphone扫二维码在哪里 苹果手机的扫描二维码功能在哪？
1、方法一：
（1）使用相机自带的扫描二维码功能，首先，打开iphone电源，回到ios的主屏幕界面；
（2）然后在主屏幕界面，从下往上滑动打开“控制中心”；
（3）在“控制中心”找到“二维码扫面”。点击打开；
（4）然后将要扫描的二维码对准摄像头；
（5）扫描完成，就可以选择打开连接了。
2、方法二：苹果手机的QQ、微信等app也具有扫描二维码的功能。
（1）在手机桌面用力按下相应app的图标呼出二级菜单；
（2）在二级菜单选择“扫一扫”即可。
IOS利用AVFoundation框架进行二维码扫描开发，扫描完成后，显示了个二维码图片，卡在这个界面上好久
在海韩帝国可以看的，更新的也很快，v+这个321524，在航空公司以及各机票售票处，未能在乘坐飞机后7日内领取行程单的旅客，可以在购票站补打行程单。2、购票后至飞机起飞后的30天内打印行程单服务有效。机场领取行程单的旅客，务必在起飞后30天内领取。3、飞机起飞后的30天以后申请打印行程单服务无效。超过30天无法打印行程单。这时需要联系承运人(航空公司)或购票的销售商协商解决。4、在指定bai的机场柜台行程单领取，一般的航空公司都会在机场设置机行程单领取柜台。5、如有不明白的问题可以咨询机场工作人员，他们会给你详细的解答。1、为保护您的合法权益，在网上预订机票，须注意查看网站上是否具备工商局颁发的网上电子标识，电信主管部门颁发的ICP证号，国际航空运输协会（IATA）颁发的国际证书。2、正规的经营航空客运代理业务的旅du行社或票务代理公司除需有固定的经营场所外,还应具备以下条件：（1）具有'国际航空运输协会'颁发的IATA执照号码。（2）具有民航局颁发的经营航空客运代理业务的许可。只有国内客票代理权的公司不可经营国际票务业务。（3）具有固定的经营场所和民航预订终端系统。（4）具有经过民航和国际航空运输协会培训合格的票务专业人员。RTHTHRTH3、为保证查到正确的票价，请询价时告知准确的去程、回程日期，并要求书面确认报价。4、航空公司会不时推出促销价格和有关信息，敬请经常留意'最新消息'栏目。5、为避免机位紧张时订不到座位，最好尽可能提前将机位订好。预订机位是不收费的，届时如决定不购票可通知订票取消
