CALayer动画

Question

我是初学者，我试着继续熟悉CALayer .

再次感谢“阿历克山德·阿克斯”、“达姆里克”和“汤米”，因为现在我可以扭曲我的CALayer了！

看上去：

​

​

我想把我的手指移到灰色UIView上(用UIView和我的“卡片”移动如下：(举个例子，如果我的手指向左移动)

• 黄牌消失&绿色的是
• 白色的地方
• ，白色的
• 蓝色的红色的

H 116而不是蓝色的卡片出现了.H 217f 218

也许我在做梦，这对我来说太难了，但如果你能给我建议，我会接受的！

谢谢！

您可以像这样使用自定义的函数

- (void)moveAndRotateLayer: (CALayer *)layer withDuration:(double)duration degreeX:(double)degreeX y:(int)degreeY angle:(float)angle autoreverseEnable:(BOOL)ar repeatTime:(int)repeat andTimingFunctionType:(NSString *)type
{
    // You should type the timing function type as "Liner", "EaseIn", "EaseOut" or "EaseInOut".
    // The default option is the liner timing function.
    // About these functions, look in the Apple's reference documents.

    CAAnimationGroup *theGroup = [CAAnimationGroup animation];

    CGPoint movement = CGPointMake(layer.position.x + degreeX, layer.position.y + degreeY);
    NSArray *animations = [NSArray arrayWithObjects:[self moveLayers:layer to:movement duration:duration], [self rotateLayers:layer to:angle duration:duration], nil];

    theGroup.duration = duration;
    theGroup.repeatCount = repeat;
    theGroup.autoreverses = ar;

    if ([type isEqualToString:@"EaseIn"]) 
    {
        theGroup.timingFunction = [CAMediaTimingFunction functionWithName: kCAMediaTimingFunctionEaseIn];
    }
    else if ([type isEqualToString:@"EaseOut"]) 
    {
        theGroup.timingFunction = [CAMediaTimingFunction functionWithName: kCAMediaTimingFunctionEaseOut];
    }
    else if ([type isEqualToString:@"EaseInOut"]) 
    {
        theGroup.timingFunction = [CAMediaTimingFunction functionWithName: kCAMediaTimingFunctionEaseInEaseOut];
    }
    else
    {
        theGroup.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear];
    }

    theGroup.animations = [NSArray arrayWithArray:animations];

    [layer addAnimation:theGroup forKey:@"movingAndRotating"];
}

这是动画的解决方案，只是为了移动和旋转图层，

但是，我知道你可以定制自己。

这对你很有好处。你能做到。

祝好运!
