<p><strong>之前开始使用ijk进行了一些简单的播放器实现，不过因为项目需要，所以又重新花了一些时间完善了一个demo</strong><br />
主要是对工具栏的逻辑进行了优化，顺便封装了一下，不过第一次做播放器，难免在一些地方有所疏漏，而且时间仓促，一些细节部分暂时还未完善。<br />
主要的一些文件：（参考ijk自带demo）<br />
<img src="media/16791192499654/16791196769070.png" alt="image.png" /></p>
<p>首先在工具栏部分主要是以下的一些东西<br />
包含了工具栏的自动消失以及工具栏上面的button的初始化（这部分还没有做autolayout，全屏后工具栏暂时未优化）</p>
<pre class="line-numbers"><code class="language-objectivec">#import <UIKit/UIKit.h>
@protocol IJKMediaPlayback;
@interface PlayerViewControl : UIControl
@property (weak, nonatomic) id<IJKMediaPlayback> delegatePlayer;
@property (strong, nonatomic) UIButton* switchBut;
@property (strong, nonatomic) UISlider* slider;
@property (strong, nonatomic) UILabel * timer;
@property (strong, nonatomic) UIButton* danmakuBut;
@property (strong, nonatomic) UIButton* fullScreenBut;
@property (strong, nonatomic) UIButton* playBut;
@property (strong, nonatomic) UIView* overlay;
@property (strong, nonatomic) UIView* buttomlay;
@property (strong, nonatomic) UIActivityIndicatorView* indicator;
- (void)refreshPlayerContrl;
- (void)showNoFade;
- (void)showAndFade;
- (void)hide;
- (void)beginDragMediaSlider;
- (void)endDragMediaSlider;
- (void)continueDragMediaSlider;
@end
</code></pre>
<p>因为要像bilibili那样能过最小化播放，于是在之前的基础上进行了修改，把ijkplayer封装成了一个uiview类型，之前的demo里面是一个controller：主要实现的还是播放器加载，以及全屏、切换源等逻辑（那个滑动调节音量和亮度的需要真机测试。。。没试过行不行）</p>
<pre class="line-numbers"><code class="language-objectivec">#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>
#import <IJKMediaFramework/IJKMediaFramework.h>
#import "PlayerViewControl.h"
@class PlayerViewControl;
@interface PlayerViewController : UIView
@property (atomic, strong) NSURL *url;
@property (atomic, retain) id <IJKMediaPlayback> player;
@property (strong, nonatomic) PlayerViewControl *playerControl;
@property (strong, nonatomic) UIView *playerView;
- (instancetype)initWithURL:(NSURL*)url withFrame:(CGRect)frame;
@end
</code></pre>
<p>另外，我把ijk必要notification部分分离了出来，方便维护和增加功能</p>
<pre class="line-numbers"><code class="language-objectivec">#import "PlayerViewController.h"
@interface PlayerViewController (Notification)
- (void)setupNotification;
- (void)removeNotification;
@end
</code></pre>
<p>需要调用的时候就只需要：</p>
<pre class="line-numbers"><code class="language-objectivec">PlayerViewController *vc = [[PlayerViewController alloc] initWithURL:[NSURL URLWithString:@"http://live.hkstv.hk.lxdns.com/live/hks/playlist.m3u8"] withFrame:CGRectMake(0, 64, self.view.frame.size.width, 200)];
[self.view addSubview:vc];
</code></pre>
<p>就可以了。当然，这只是简单的封装，更多需求自然要自己增加</p>
<p>详细的代码可以下载我的demo进行参考：<br />
