Solution

• Enter Build Settings
• Search for OTHER LINKER FLAGS

-frameworkThis logo is for .frameworkthe files you bring , so you need to find out those unnecessary -frameworkframes and -frameworkdelete the ones below it .
For example, I don’t have MJRefresh here .framework, so just delete the -l"MJRefresh"following -framework.
