I tried to add the cordova project to my In an existing ios project. I can successfully compile the application. But when I run it, I get this exception of cordovaSettingForKey.

– [__ NSDictionaryM cordovaSettingForKey:]: Unrecognized Selector sent to instance 0x147052a30

EXCEPTION THROW: – [__ NSDictionaryM cordovaSettingForKey:]: Unrecognized selector sent to instance 0x147052a30

Anyone knows how to solve the problem

This is the header file

That’s how I call it

MainViewController * layer = [[MainViewController alloc] initWithNibName:@"MainViewController" bundle:nil ];

Thank you

Try to add -ObjC to the target’s “other link flags” Medium. Note: The cordova documentation says that it is the “-Obj-C” flag, which cannot solve the problem.
