iOS开发 - 播放系统音效、自定义音效

分享到:
播放系统音效、自定义音效工具类
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

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

2.2系统音效,以Tock为例

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

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