开始图层动画的代码:
class="brush:objc;gutter:true;"> //mySuperLayer父图层 CFTimeInterval pausedTime = [self.mySuperLayer timeOffset]; if (pausedTime > 0)//在暂停后才能使用 { self.mySuperLayer.speed = 1.0; self.mySuperLayer.timeOffset = 0.0; self.mySuperLayer.beginTime = 0.0; CFTimeInterval timeSincePause = [self.mySuperLayer convertTime:CACurrentMediaTime() fromLayer:nil] - pausedTime; self.mySuperLayer.beginTime = timeSincePause; }
暂停图层动画的代码:
CFTimeInterval pausedTime = [self.mySuperLayer convertTime:CACurrentMediaTime() fromLayer:nil]; self.mySuperLayer.speed = 0.0; self.mySuperLayer.timeOffset = pausedTime;
