iOS开发——播放系统音效、自定义音效

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：

[cpp] view
plaincopyprint?

@interface WQPlaySound : NSObject

{

SystemSoundID soundID;

}

/**

* @brief 为播放震动效果初始化

*

* @return self

*/

-(id)initForPlayingVibrate;

/**

* @brief 为播放系统音效初始化(无需提供音频文件)

*

* @param resourceName 系统音效名称

* @param type 系统音效类型

*

* @return self

*/

-(id)initForPlayingSystemSoundEffectWith:(NSString *)resourceName ofType:(NSString *)type;

/**

* @brief 为播放特定的音频文件初始化（需提供音频文件）

*

* @param filename 音频文件名（加在工程中）

*

* @return self

*/

-(id)initForPlayingSoundEffectWith:(NSString *)filename;

/**

* @brief 播放音效

*/

-(void)play;

@end

@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] view
plaincopyprint?

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

[sound play];

2.2系统音效，以Tock为例

[cpp] view
plaincopyprint?

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] view
plaincopyprint?

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

[sound play];
