iOS 模仿QQ音乐用Xcode写的一个播放器

我使用AvPlayer写的,所以大家一定得记住要导入AvFoundation的库，话不多说，直接上代码

这里我是把AvPlayer封装到了一个类里,

//
//  CXPlayMvViewController.m
//  LeeMusic

//#import "LoveMusicPlayer.h"
#import <AVFoundation/AVFoundation.h>
@implementation LoveMusicPlayer+ (LoveMusicPlayer *)sharePlayer{static LoveMusicPlayer* Player = nil;if (Player==nil) {Player =[[LoveMusicPlayer alloc] init];}return Player;
}- (void)playWithURL:(NSString *)url{AVPlayerItem * item = [[AVPlayerItem alloc] initWithURL:[NSURL URLWithString:url]];[self replaceCurrentItemWithPlayerItem: item];[self play];
}
@end

这里是在ViewController里完成的代码，我是直接找了一个音乐播放器的歌单的Url然后在这里请求数据的。
其实做起来也没那么难，AvPlayer它本身就有很多方法供大家使用，比如从url中获取歌曲总长（不过大家它给的时间是以秒为单位的，大家别忘了把它化成分秒，下面我也写到，大家可以参考），比如播放器音量，直接跟你写的音量slider绑定到一起等等。大家可以慢慢看，先把页面铺完(歌曲的图片转动我为了偷工减料就直接用计时器写了，看起来有点Low)，再把该完成的方法写了就完事了。
