错误说明:
clang: error: linker command failed with exit code 1 (use -v to see invocation)
推荐答案
出现此错误是由于文件重复.有时我们使用多个框架，但这些框架也有其他框架也有的文件.因此，我们需要识别重复文件并删除它们.
This error occur due to duplicate of files. Sometimes we use multiple frameworks but those framework have files which other framework have too. So, we need to identify the duplicate file and remove them.
