我试图播放AlertSound，但有4个错误，这是我的功能：
#import "AudioToolbox/AudioServices.h"
+(void)jouerSon:(NSString *)fichierSon:(NSString *) extensionFichier
{
NSString* soundPath = [[NSBundle mainBundle] pathForResource:fichierSon ofType:extensionFichier];
CFURLRef baseURL = (CFURLRef) [NSURL fileURLWithPath:soundPath];
SystemSoundID mysound;
AudioServicesCreateSystemSoundID(baseURL,&mysound);
AudioServicesPropertyID flag = 0;
AudioServicesSetProperty(kAudioServicesPropertyIsUISound,sizeof(SystemSoundID), &mysound, sizeof(AudioServicesPropertyID), &flag);
AudioServicesPlayAlertSound(mysound);
//AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);
AudioServicesDisposeSystemSoundID(mysound);
}
这是日志错误：

最佳答案
您需要将AudioToolbox框架添加到项目中。
光靠进口是不够的。
