調用方法步驟：
1.加入AudioToolbox.framework到工程中
2.調用WQPlaySound工具類

2.1震動

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

2.2系統音效，以Tock為例

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

2.3自定義音效，將tap.aif音頻文件加入到工程

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