In fact, can also be used to play network audio, but it is the entire network file download down, in the actual development will be more expensive to do not recommend.

Here is the relevant code:

#import "ViewController.h"

#import <AVFoundation/AVFoundation.h>

@interface viewcontroller ()

<

Avaudioplayerdelegate

>

Set the global object, or there will be no sound to appear

@property (nonatomic,strong) avaudioplayer *audioplayer;

@property (nonatomic,strong) Nstimer *timer;

@property (nonatomic,strong) Nsarray *mp3array;

@property (nonatomic) nsinteger currentMp3;

@property (nonatomic,strong) Nsarray *lrcarray;

@property (nonatomic,strong) CYPARSERLRC *parser;

@property (nonatomic)nsinteger currentrow;

@end

@implementation Viewcontroller

-(void) Initwithmp3path: (nsstring *) Mp3path Lrcpath: (nsstring *) Lrcpath

{

//initwithcontentsofurl Path (local)

self. Audioplayer = [[avaudioplayer alloc] initwithcontentsofurl: [nsurl Fileurlwithpath: Mp3path] error:nil];

// ready to play

[self. Audioplayer preparetoplay];

// set sound

self. Audioplayer. Volume = 0.5f;

Set up proxy

self. Audioplayer. Delegate = self;

// Set the maximum value of the progress bar

//duration Total time of current music

self. Song. MaximumValue = self. Audioplayer. Duration;

// Parse lyrics

[self. Parser PARSERLRC: Lrcpath];

// next refresh tableView

[self. TableView reloaddata];

self. Timer = [nstimer scheduledtimerwithtimeinterval:. 1f target: Self selector:@selector(timechange) userInfo:nil repeats:YES ];

}
