CABasicAnimation动画

使用CABasicAnimation动画:

　　　

 CALayer *znzLayer; = [[CALayer alloc]init];
//创建不断该表CALayer的transform属性动画CABasicAnimation *anim = [CABasicAnimation animationWithKeyPath:@"transform"];CATransform3D fromValue = znzLayer.transform;//设置动画开始的属性值anim.fromValue = [NSValue valueWithCATransform3D:fromValue];//绕z轴旋转heading弧度的变换矩阵CATransform3D toValue = CATransform3DMakeRotation(headings, 0, 0, 1);//设置动画结束的属性anim.toValue = [NSValue valueWithCATransform3D:toValue];anim.duration = 0.5;//持续时间anim.removedOnCompletion = YES; //如果需要继续使用本动画可以不用设置该属性,默认为NO,//设置动画结束后anzLayer的变换矩阵znzLayer.transform = toValue;//为znzLayer添加动画[znzLayer addAnimation:anim forKey:nil];
