只需按一下按钮，我就会在不同的if语句中将声音文件附加到我的应用中。出于某种原因，一旦按下按钮，其中一个声音总是播放（谢谢），我无法找到音源。有时，它与现有声音重叠。 这是我的代码：

使用更清洁方法的示例代码：
// not all values present, just a sample here
NSDictionary *stringsToSounds = @{@"friend":@"You're my best friend", @"hat are you doing":@"I'm talking to you", @"chips":@"chipds"};
NSDictionary *stringsToLabels = @{@"friend":@"You're my best friend", @"hat are you doing":@"I'm talking to you", @"chips":@"Ooooh. I love chips."};
for(NSString *s in stringsToSounds) {
if([string rangeOfString:s] != NSNotFound) {
if(stringsToLabels[s]) {
[label setText:stringsToLabels[s]];
}
[self playSound:stringsToSounds[s]];
break;
}
}
和方法playSound看起来像：
-
(void) playSound(NSString *) soundFileName {
SystemSoundID SoundID;
NSString *soundfile= [[NSBundle mainBundle] pathForResource:soundFileName ofType:@"mp3"];
AudioServicesCreateSystemSoundID((__bridge CFURLRef)[NSURL fileURLWithPath:soundfile], &SoundID );
AudioServicesPlaySystemSound(SoundID);
NSLog(@"sound played");
}

正如其他海报建议的那样，您可以使用字典来查找要为不同标签值播放的声音。代码可能如下所示：
-(void) playSoundForLabelText: (NSString *) text
{
//Build a dictionary where each key is the string to search for, and the value is the name of the sound to play.
NSDictionary *soundFileNames = @{@"I was born one day in an Apple Computer. I can't seem to remember when that was.": @"Your birthday",
@"Ooooh. I love chips.": @"chips",
@"Cloudy with a chance of meatballs, GET It? But really, click below": @"Weather"};
//Attempt to fetch a sound file name for the key in "text"
NSString *soundName = soundFileNames[text];
if (soundName != nil)
{
NSString *soundfile= [[NSBundle mainBundle] pathForResource: soundName ofType:@"mp3"];
AudioServicesCreateSystemSoundID((__bridge CFURLRef)[NSURL fileURLWithPath:soundfile], &SoundID );
AudioServicesPlaySystemSound(SoundID);
NSLog(@"Played sound %@", soundName);
}
else
NSLog(@"No sound found for key %@", text);
}
然后你将这个方法用于这样的代码：
NSString *labelText = label.text;
[self playSoundForLabelText: labelText];
此代码未经过优化。它创建了每次都将标签文本映射到声音文件名的字典，这是低效的，但它为您提供了一般的想法。
BTW，AVAudioPlayer通常比AudioServicesCreateSystemSoundID更适合播放声音。在Xcode文档中搜索AVAudioPlayer以了解更多信息。
