ios - No visible @interface for 'JSQSystemSoundPlayer' error -

-

i added files:

jsqsystemsoundplayer.h jsqsystemsoundplayer.m

into project , rose next error:

no visible @interface 'jsqsystemsoundplayer' declares selector 'playalertsoundwithfilename:fileextension:'

i searched lot could'n find solution. can know how solve it?

this declaration of method 

- (void)playalertsoundwithfilename:(nsstring *)filename                  fileextension:(nsstring *)fileextension                     completion:(nullable jsqsystemsoundplayercompletionblock)completionblock;

you're missing completion block, there no such method 2 parameters

here example how use it

[[jsqsystemsoundplayer sharedplayer] playsoundwithfilename:@"mysoundfile"                                              fileextension:kjsqsystemsoundtypeaif                                                 completion:^{                                                   // completion block code                                                 }];

edit: per comments

if @ declaration of playsoundwithfilename: fileextension: completion: method find 

@param completionblock block called after sound has stopped playing.

which means whatever want after sound has stopped playing. if don't want either can pass nil or empty block above
