我已将 AdMob 集成到我的应用程序中,但是当我尝试显示任何广告时,它会出现以下错误:
"_OBJC_CLASS_$_CJSONDeserializer", referenced from:
objc-class-ref-to-CJSONDeserializer in libAdMob.a(AdMobAd.o)
objc-class-ref-to-CJSONDeserializer in libAdMob.a(AdMobSearchViewController.o)
objc-class-ref-to-CJSONDeserializer in libAdMob.a(AdMobOpener.o)
"_OBJC_CLASS_$_CJSONSerializer", referenced from:
objc-class-ref-to-CJSONSerializer in libAdMob.a(AdMobAd.o)
objc-class-ref-to-CJSONSerializer in libAdMob.a(AdMobWebView.o)
objc-class-ref-to-CJSONSerializer in libAdMob.a(AdMobFlexWebView.o)
有谁知道出了什么问题?
