Error in compile: No visible @interface for 'RtmpWrapper' declares the selector..

[milinka]

Error:
--> BOOL ret = [rtmp rtmpOpenWithURL:rtmpDest enableWrite:YES];
rtmp-wrapper-master/rtmpTester/ViewController.m:32:22: No visible @interface for 'RtmpWrapper' declares the selector 'rtmpOpenWithURL:enableWrite:'

..every reference to rtmp will trigger same error..

• I tried to add new target (ios) single view application, with button (start)..
  copy the code in description.. and copy build settings from rtmp-wrapperTests, but cannot app to compiled ?

using xcode: 7.2
