Question

When I try running my Xcode Project it fails with an error stating that I have duplicate symbols. Below is the way I sovled this error. Hope to help you~

The error info:

From the error info I found that WPBuySkinAlertView maybe the duplicate class.So I seach the file in the project.

There are two WPBuySkinAlertView files in the project.

So, next time when you come with this error, check your project according to the error info, find the duplicate classes and remove the one.
