103 | self.layer.speed = 0.0; 104 | self.layer.timeOffset = pausedTime; 105 | ``` 106 | 107 | - 恢复 resume 108 | - 恢复layer动画即可 109 | 110 | ``` 111 | CFTimeInterval pausedTime = [self.layer timeOffset]; 112 | self.layer.timeOffset = 0.0; 113 | self.layer.beginTime = 0.0; 114 | self.layer.speed = 1.0; 115 | CFTimeInterval timeSincePause = [self.layer convertTime:CACurrentMediaTime() fromLayer:nil] - pausedTime; 116 | self.layer.beginTime = timeSincePause; 117 | ``` 118 | 119 | 120 | - 关闭 close 121 | ``` 122 | [self.layer removeAllAnimations]; 123 | [self removeFromSuperview]; 124 | ``` 125 | 126 | ##插件使用 127 | [下载项目]()导入到项目中，使用时`import 'BarrageKit.h'`即可 128 | ``` 129 | _manager = [BarrageManager manager]; 130 | 131 | //出现的View 132 | _manager.bindingView = self.view; 133 | 134 | //delegate 135 | _manager.delegate = self; 136 | 137 | //弹幕显示位置 138 | _manager.displayLocation = BarrageDisplayLocationTypeDefault; 139 | 140 | //滚动方向 141 | _manager.scrollDirection = BarrageScrollDirectRightToLeft; 142 | 143 | //滚动速度 144 | _manager.scrollSpeed = 30; 145 | 146 | //收到内存警告的处理方式 147 | _manager.memoryMode = BarrageMemoryWarningModeHalf; 148 | 149 | //刷新时间 150 | _manager.refreshInterval = 1.0; 151 | 152 | //开始滚动 manager主动获取弹幕，另外一种方式，`[_manager showBarrageWithDataSource:m]` 退出弹幕即可 153 | [_manager startScroll]; 154 | ``` 155 | **Tips:** 156 | - ①如果弹幕为投票类型的弹幕时，请重写`ViewController`的`touchesBegan` 方法 157 | 158 | ``` 159 | - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { 160 | UITouch *touch = [touches anyObject]; 161 | CGPoint touchPoint = [touch locationInView:self.view]; 162 | [[_manager barrageScenes] enumerateObjectsUsingBlock:^(BarrageScene * _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) { 163 | if ([obj.layer.presentationLayer hitTest:touchPoint]) { 164 | //弹幕类型为投票类型时，为弹幕添加点击事件，请在此处添加 165 | /* if barrage's type is ` BarrageDisplayTypeVote `, add your code here*/ 166 | NSLog(@"message = %@",obj.model.message.string); 167 | } 168 | }]; 169 | } 170 | ``` 171 | 172 | - ②重写`ViewController`的`dealloc`方法，执行`BarrageManager`的`toDealloc` 173 | - ③ViewController收到内存警告时，`[_manager didReceiveMemoryWarning];`将会按照`memoryMode`指定的方法清楚缓冲池 174 | ``` 175 | - (void)didReceiveMemoryWarning { 176 | [super didReceiveMemoryWarning]; 177 | // Dispose of any resources that can be recreated. 178 | 179 | // 收到内存警告时，清楚弹幕缓冲池 When you receive a memory warning，clean the barrage's cache 180 | [_manager didReceiveMemoryWarning]; 181 | } 182 | ``` 183 | - ④如果要高度自定义弹幕显示，可以修改`BarrageScene`中的初始化代码 184 | 185 | 186 | ##最后 187 | ###大家查看项目后，欢迎[issue](https://github.com/jiachenmu/BarrageKit/issues)，同时有其他的功能或建议欢迎提出来，简书、github均可。 188 | - [项目及Demo下载地址](https://github.com/jiachenmu/BarrageKit) 189 | - ![IOS开发交流群](http://i2.buimg.com/567571/cd9b3c8edd6f164c.png) 190 | --------------------------------------------------------------------------------
