Ios 带有UIViewAnimationOptionRepeat的动画不重复

我有一段代码，应该循环动画，直到它运行到另一个形状。但是，它只运行一次，不执行任何后续操作。

您正在使用CoreAnimation对象，将不受UIView动画块的影响，请删除UIView动画块并添加：

[UIView animateWithDuration:speedOfCutout
                      delay:0.2f
                    options:UIViewAnimationCurveEaseInOut | UIViewAnimationOptionRepeat //| UIViewAnimationOptionAutoreverse
                 animations:^{

                     CABasicAnimation *animation = [CABasicAnimation animation];
                     animation.keyPath = @"position.y";
                     animation.fromValue = @77;
                     animation.toValue = @600;
                     animation.duration = speedOfCutout;

                     [cutout.layer addAnimation:animation forKey: @"basic"];
                     cutout.layer.position = CGPointMake(160, 61);
                     [cutout.layer addAnimation:animation forKey: @"basic"];
                     cutout.layer.position = CGPointMake(160, 61);

                     [cutout.layer addAnimation:animation forKey: @"basic"];
                     cutout.layer.position = CGPointMake(160, 61);

                 }
                 completion:^(BOOL fin) {
                 }];

if (CGRectIntersectsRect(cutout.frame, shape.frame)) {
    cutout.hidden = YES;
    shape.hidden = YES;

    [cutoutMovementTimer invalidate];

    [self gameOver];

}

会有用的。

试试这个： 设置animation.repeatCount=-1；

完成块是否处理形状更改事件并停止动画。

可能是因为第一个选项不是选项，所以忽略了所有选项，所以它不起作用。我想应该是UIViewAnimationOptionCurveEaseInOut

animation.autoreverses = YES;
animation.repeatCount = HUGE_VAL;
