iOS开发——播放系统音效、自定义音效

需求大致分为三种：
1.震动
2.系统音效（无需提供音频文件）
3.自定义音效（需提供音频文件）
我的工具类的封装：

@implementation WQPlaySound

-(id)initForPlayingVibrate
{
    self = [super init];
    if (self) {
        soundID = kSystemSoundID_Vibrate;
    }
    return self;
}

-(id)initForPlayingSystemSoundEffectWith:(NSString *)resourceName ofType:(NSString *)type
{
    self = [super init];
    if (self) {
        NSString *path = [[NSBundle bundleWithIdentifier:@"com.apple.UIKit"] pathForResource:resourceName ofType:type];
        if (path) {
            SystemSoundID theSoundID;
            OSStatus error = AudioServicesCreateSystemSoundID((__bridge CFURLRef)[NSURL fileURLWithPath:path], &theSoundID);
            if (error == kAudioServicesNoError) {
                soundID = theSoundID;
            }else {
                NSLog(@"Failed to create sound ");
            }
        }

    }
    return self;
}

-(id)initForPlayingSoundEffectWith:(NSString *)filename
{
    self = [super init];
    if (self) {
        NSURL *fileURL = [[NSBundle mainBundle] URLForResource:filename withExtension:nil];
        if (fileURL != nil)
        {
            SystemSoundID theSoundID;
            OSStatus error = AudioServicesCreateSystemSoundID((__bridge CFURLRef)fileURL, &theSoundID);
            if (error == kAudioServicesNoError){
                soundID = theSoundID;
            }else {
                NSLog(@"Failed to create sound ");
            }
        }
    }
    return self;
}

-(void)play
{
    AudioServicesPlaySystemSound(soundID);
}

-(void)dealloc
{
    AudioServicesDisposeSystemSoundID(soundID);
}
@end

调用方法步骤：
1.加入AudioToolbox.framework到工程中
2.调用WQPlaySound工具类

2.1震动

[cpp]
WQPlaySound *sound = [[WQPlaySound alloc]initForPlayingVibrate];
[sound play];

2.2系统音效，以Tock为例

[cpp]
WQPlaySound *sound = [[WQPlaySound alloc]initForPlayingSystemSoundEffectWith:@"Tock" ofType:@"aiff"];
[sound play];

2.3自定义音效，将tap.aif音频文件加入到工程

[cpp]
WQPlaySound *sound = [[WQPlaySound alloc]initForPlayingSoundEffectWith:@"tap.aif"];
[sound play];
