AVPlayer

AVPlayer的功能很强大,既可以播放视频, 也可以播放音频, 既可以播放本地的, 也可以播放网络的;

下面是我封装的一个AVPlayer的Demo,在ViewController中实现

工程中的所有东西如下:

创建一个PlayView类,PlayView.h中的代码如下

#import <UIKit/UIKit.h>
#import <AVFoundation/AVFoundation.h>

@class PlayView;
@protocol PlayViewDelegate  <NSObject>

@optional

//向左转全屏播放
- (void)fullScreen:(PlayView *)playerView;
//左全屏转回小窗口播放
- (void)normalScreen:(PlayView *)playerView;
//向右转全屏播放
- (void)turnRight:(PlayView *)playerView;
//右全屏转窗口播放
- (void)rtghtTurnBack:(PlayView *)playerView;
//播放失败
- (void)AVPlayerStatusFailed:(PlayView *)playerView;

@end

@interface PlayView : UIView

@property (nonatomic, strong) NSURL *url;
@property (nonatomic, strong) AVPlayer *player;
@property (nonatomic, strong) UIView *container;
@property (nonatomic, strong) AVPlayerItem *playerItem;
@property (nonatomic, strong) UIButton *playButton;
@property (nonatomic, strong) UIButton *fullButton;
@property (nonatomic, strong) UILabel *startTime;
@property (nonatomic, strong) UILabel *endTime;
@property (nonatomic, strong) UILabel *gang;
@property (nonatomic, strong) UISlider *progress;
@property (nonatomic, strong) UISlider *playableProgress;
@property (nonatomic, strong) UISlider *volume;
@property (nonatomic, strong) UIView *backView;
@property (nonatomic, strong) UIActivityIndicatorView *actiity;
@property (nonatomic, assign) BOOL isSliding;
@property (nonatomic, assign) BOOL istouched;
@property (nonatomic, strong) NSTimer *timer;
@property (nonatomic, strong)UIImageView *imageView;
@property (nonatomic, assign)BOOL _isSmall;
@property (nonatomic, strong) NSString *urlStr;
@property (nonatomic, strong)AVPlayerLayer *playerLayer;

@property (nonatomic, assign)id<PlayViewDelegate> delegate; 

@end
