[GADSlot state]: unrecognized selector sent to instance in iphone - ios

Question

I am new to iOS development.
I am trying to implementing admob ads in iOS in my phonegap app so I googled & found somveadmob without plugin.
after following all procedure,
I got an error MyApp[2388:70b] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[GADSlot state]: unrecognized selector sent to instance 0x10415920'**
so I google about & found that I have to change other Linker flags. (-ObjC)here
I have tried it but it is not working.
I am getting this error.
this solution also not working for me. [GADSlot state]: unrecognized selector sent to instance

I think, GADBannerView is not set up correctly. If you have the source for GADBannerView, examine it and see where the object reference is coming from.U should try to solve this error in that direction.
check ur admob version as well, becoz GDBBannerview is a part of Admob this might accour from that code.
or else try with other (older or newer version) of admob api.
