我正在制作一个应用程序,一旦计时器达到一定的限制振动.

但是,在打电话时

AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);

Xcode出现两个错误:

Undefined symbols for architecture i386:
  "_AudioServicesPlaySystemSound", referenced from:
      -[drawGraph drawRect:] in drawGraph.o
ld: symbol(s) not found for architecture i386

和

clang: error: linker command failed with exit code 1 (use -v to see invocation)

有关导致这些错误的原因的任何想法？
