现在实现了从右往左滚动的弹幕效果, 并且添加了中间的弹幕

弹幕内容为AttributeString 支持表情图片等等

具体里面的实现思路来自: 大家可以参考下

效果如下:

使用方法:

-----------------------------------

### 创建CFDanmakuView对象, 进行配置, 并添加到View上 

    _danmakuView = [[CFDanmakuView alloc] initWithFrame:rect];

    _danmakuView.duration = 6.5;

    _danmakuView.centerDuration = 2.5;

    _danmakuView.lineHeight = 25;

    _danmakuView.maxShowLineCount = 15;

    _danmakuView.maxCenterLineCount = 5;

    

    _danmakuView.delegate = self;

    [self.view addSubview:_danmakuView];

    

### 配置弹幕的数据

    CFDanmaku* danmaku = [[CFDanmaku alloc] init];

    [danmakus addObject:danmaku];

    [_danmakuView prepareDanmakus:danmakus];

    // 对应视频的时间戳

    @property(nonatomic, assign) NSTimeInterval timePoint;

    // 弹幕内容

    @property(nonatomic, copy) NSAttributedString* contentStr;

    // 弹幕类型(如果不设置 默认情况下只是从右到左滚动)

    @property(nonatomic, assign) CFDanmakuPosition position;

### 遵守协议, 并实现代理方法

    // 获取视频播放时间

    - (NSTimeInterval)danmakuViewGetPlayTime:(CFDanmakuView *)danmakuView

    {

      if(_slider.value == 1.0) [_danmakuView stop]

        ;

      return _slider.value*120.0;

    }

    // 是否正在加载视频中

    - (BOOL)danmakuViewIsBuffering:(CFDanmakuView *)danmakuView

    {

      return NO;

    }
