ios - 每五秒钟发出一次声音循环警报

我正在尝试每五秒钟编写一个简单的循环声音警报

我该如何添加

调整cydia

Tweak.xm模板

     if (lowenabled) {
      if ([batString isEqualToString:lowbatPercent_String]) {
        if (lowplayer) {
          return;
        }

        if (lowsound == 0)
          soundFilePath = [NSString stringWithFormat:@"%@/Super Mario.mp3", bundlePrefix];
        else if (lowsound == 1)
          soundFilePath = [NSString stringWithFormat:@"%@/Super Mario 1.mp3", bundlePrefix];

        soundFileURL = [NSURL fileURLWithPath:soundFilePath];

        lowplayer = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL error:nil];
        lowplayer.numberOfLoops = 3;
        [lowplayer play];
      } else {
        if (lowplayer) {
          lowplayer = nil;
        }
      }
    }
}
%end

最佳答案

包括触发计时器：

NSTimer *timer = [NSTimer scheduledTimerWithTimeInterval:5.0 target:self selector:@selector(playSound:) userInfo:nil repeats:YES];
[timer fire];

将方法放在同一类中：

- (void)playSound {
 // the code you included here that plays the sound
}
