我必须在iPhone中创建一个应用程序,它可以为文本,邮件,地图,照片等生成QRCode.还可以解码QRCode.有没有人知道它的API或例子？
提前致谢
我的应用程序在xcode 4.4.1中运行良好,但我刚刚更新到4.5,现在我遇到了一个clang错误.甚至不确定它讲的是什么,有没有人经历过这一点,或者可以阐明我如何修复它？这是确切的错误:

ld: file is universal (3 slices) but does not contain a(n) armv7s slice: …我一直在寻找扫描1d条形码的解决方案,并提出了以下答案:ios应用程序中的QR码扫描
我正在为iOS 8开发,对上述问题的第二个答案解决了我们不再需要使用第三方库这一事实.这似乎相对简单.
有些应用程序可以扫描条形码,然后您可以在设备上查看条形码.我假设他们正在从扫描的条形码创建一个UIImage.但是我不确定如何在我的应用程序中实现相同的功能.
有没有人知道处理这种行为的代码示例或库？
