为什么音频在模拟器中工作但在我的iPad上没有？

问题描述

我正致力于创建一个非常简单的应用。 2个按钮，都播放声音。每个剪辑持续1秒钟并响应TouchUpInside。它们是我在iTunes中转换的.caf文件。

I am working on creating a very simple app. 2 buttons, both play sound. Each clip lasts 1 second and responds to "TouchUpInside". They are .caf files that I converted in iTunes.

这是我的代码，再一次，它可以在模拟器中运行但不在设备上运行：

Here is my code, once again, it works in the simulator but not on the device:

enter code here- (void)viewDidLoad {

    NSLog(@"InView did load");

AudioServicesCreateSystemSoundID ((CFURLRef)[NSURL fileURLWithPath:[[NSBundle mainBundle]pathForResource:@"bigaif" ofType:@"caf"]], &systemSoundID);


    AudioServicesCreateSystemSoundID((CFURLRef)[NSURL fileURLWithPath:[[NSBundle mainBundle]
                                                                   pathForResource: @"smallwav" ofType:@"wav"]],
                                                                    &systemSoundIDTwo);

}

-(IBAction) playSound:(id) sender {
AudioServicesPlaySystemSound(systemSoundID);
}

-(IBAction) playSoundTwo:(id) sender {
AudioServicesPlaySystemSound(systemSoundIDTwo);

}

推荐答案

我找到了答案。我正在使用SystemSound，你知道什么，我的设备设置中的系统声音已静音。

I found my answer. I was using SystemSound and what do you know, I had my system sounds muted in my device settings.
