CALayer的动画

Question

我是初学者，我想继续CALayer熟悉自己...

再次感谢@Alexsander埃克斯，@DHamrick和@Tommy因为现在我可以扭曲我的CALayer！

它看起来像：

我想移动我的手指上的灰UIView（与touchesBegan/touchesMoved/touchesEnded）和我的 “卡” 移动是这样的： （对于为例，如果我向左移动了我的手指）

• 黄牌消失&绿色的看法是地方
• 白走绿色的地方
• 红白色
• 蓝色红色的
• 和，而不是蓝卡一黑一出现...

也许我是在做梦，它的到对我来说很难，但如果你可以给我建议，我会接受它！

谢谢！

您可以使用自定义功能，这样

- (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移动和旋转层，

，但是，我知道，你可以自定义自己。

这对你很好。你可以做到。

祝你好运！
