极光IM监听方法一写就报错

我只要在项目里一写这个监听方法

   func onReceive(_ event: JMSGUserLoginStatusChangeEvent!) {
        print("收到监听：\(event)")
    }

就会在编译时报错

Undefined symbols for architecture arm64:
  "_OBJC_CLASS_$_JMSGUserLoginStatusChangeEvent", referenced from:
      objc-class-ref in AppDelegate+Jmsg.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

其它监听方法写了就没事，怎么这个关键的监听方法一写就编译报错？

用的cocoapods导入的，来回删了，导入试了好几次了还是不行

有没有pod里导入的库有冲突了？

    pod 'Masonry'
    pod 'Alamofire'
    pod 'SwiftyJSON'
    pod 'Kingfisher'
    pod 'AliyunPlayer_iOS/AliyunVodPlayerSDK'
    pod 'RealmSwift'
    pod 'JPush'
    pod 'JMessage'
