音乐的播放

- 暂停和停止的效果木有区别!

#import "ViewController.h"#import@interface ViewController ()

//这个要用�强指针是因为  播放器要持续播放,记录之后,走出ViewDidload方法也会存在

@property(nonatomic,strong) AVAudioPlayer * player;

@end

@implementation ViewController

- (void)viewDidLoad {

[super viewDidLoad];

//准备URl

NSURL * URl= [[NSBundle mainBundle] URLForResource:@"童话.mp3" withExtension:nil];

//实例化播放器

AVAudioPlayer * player = [[AVAudioPlayer alloc]initWithContentsOfURL:URl error:nil];

//准备 不谢这个方法也是可以的,这个方法会开辟空间,如果不写自动调用,谢了效果更好;

[player prepareToPlay];

self.player = player;

}

- (IBAction)start:(UIButton *)sender {

[self.player play];

}

- (IBAction)pause:(UIButton *)sender {

[self.player pause];

}

- (IBAction)stop:(id)sender {
