Getting Error on compiling project with Parse

Question

I have followed all the steps specified https://www.parse.com/apps/quickstart#parse_push/ios/native/existing and also tried to add Parse Framework from cocoPods but still getting these following duplicate symbol errors, the IOS min version is 7.0 and objective c is used. The errors are:

duplicate symbol _BFTaskMultipleExceptionsException in:

Answer 1

It appears that you are trying to compile the same code twice. This is throwing you an error and may have been caused by you installing the library and also the cocoaPods file. Another possible reason would be that you have same class implementation into two different files. However, I wouldn't expect that with a third party library. In order to fix that, the easiest way would probably to just delete the project ans start with a clean one. If that isn't possible, delete the cocoaPod, delete the framework and any files that you installed, clean the cache and build the project. It should compile without any problem. Then just install the SDK once.

Hope that helps, Julian

在这里找到解决方案： https : //stackoverflow.com/a/29724276/4841900原因是Bolts和FacebookSDK相互冲突，所以我得到了重复的符号错误。
