CALayer的動畫

Question

我是初學者，我想繼續CALayer熟悉自己...

再次感謝@Alexsander埃克斯，@DHamrick和@Tommy因爲現在我可以扭曲我的CALayer！

它看起來像：

我想移動我的手指上的灰UIView（與touchesBegan/touchesMoved/touchesEnded）和我的 「卡」 移動是這樣的： （對於爲例，如果我向左移動了我的手指）

• 黃牌消失&綠色的看法是地方
• 白走綠色的地方
• 紅白色
• 藍色紅色的
• 和，而不是藍卡一黑一出現...

也許我是在做夢，它的到對我來說很難，但如果你可以給我建議，我會接受它！

謝謝！

您可以使用自定義功能，這樣

- (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"]; 
} 

這是動畫的解決方案只是移動和旋轉層，

，但是，我知道，你可以自定義自己。

這對你很好。你可以做到。

祝你好運！
