在iPhone中的应用内检索电子邮件 [英] Retrieve E-mail in In-app in iPhone

问题描述

目前我的项目在IOS开发目标3.2中工作得很完善，但是一旦开发目标为4.0或更高版本。它给我错误。以下是错误：

架构i386的未定义符号：
_OBJC_CLASS _ $ _ MessageWebLayer，引用来自：

 ld：没有找到符号i386 
 collect2：ld返回1退出状态
  

另外在上面的错误显示在我ssageWebLayer 与相同github上的。那么在构建设置或开发目标中需要做哪些更改才能在iOS 4.0或更高版本上运行。我在构建设置中尝试了很多变化，但是在github中的链接表示，在4.0或更高版本中不支持MessageWebLayer。任何人都可以帮助我吗？

如果这个代码不可能，那么iPhone中的其他类可以让我在In-App中检索电子邮件？ / p>

解决方案

没有公开API可以从iOS中的邮件应用程序中检索电子邮件标识。

Currently my project is working perfectly on IOS development target 3.2 But as soon as i will do development target 4.0 or higher. It gives me error. Following is the error:

Also in above error shows in MessageWebLayer which is same as on github. So What changes i need to do in Build Settings or Development target to run on iOS 4.0 or higher. I tried lots of changes in build settings but then Link in github says MessageWebLayer is not supported in 4.0 or higher. Can any one help me in this matter?

If it is not possible for this code then what other classes in iPhone allows me to retrieve email in In-App??

解决方案

There is no public api's to retrieve Email Id from Mail app in iOS.
