CATransform3DGetAffineTransform用於翻轉一個接一個地被調用的視圖不工作

Question

我正在開發一個水族館應用程序。我需要在其中產生魚的動作。魚應該游泳，當到達水族館的一端時應該轉動（或翻轉）並移動到另一端，再次轉動（或翻轉）並且回到其原始位置。

fishforword motion正常工作，它也輪到（翻轉）達到其結束。但是當它到達另一端時，翻轉動畫加上進一步的動畫突然跳過。

以下是我使用的代碼.....

CGFloat originalChildXpos = fishView.frame.origin.y; 

/************************************** Animation 1 **************************************************************/ 

[UIView animateWithDuration:15.0 
         delay:1.0 
        options:UIViewAnimationOptionCurveEaseInOut 
       animations:^{       
        fishView.frame =CGRectMake(0, fishView.frame.origin.y, fishView.frame.size.width, fishView.frame.size.height);       
       }completion:NULL]; 


/*********************************** Animation 2 ****************************************************************/ 
[UIView animateWithDuration:2.4 
         delay:3.0 
        options:UIViewAnimationOptionCurveEaseInOut 
       animations:^{ 
        fishView.transform = CATransform3DGetAffineTransform(CATransform3DMakeRotation(M_PI, 0.0, 1.0, 0.0)); 

       }completion:NULL]; 



/********************************* Animation 3 ****************************************************************/ 
[UIView animateWithDuration:10 
         delay:3.4 
        options:UIViewAnimationOptionCurveEaseInOut 
       animations:^{ 
        fishView.frame = CGRectMake(-aquariumView.frame.size.width, fishView.frame.origin.y, fishView.frame.size.width, fishView.frame.size.height); 
       }completion:NULL]; 



/*************************************** Animation 4 *****************************************************/ 
[UIView animateWithDuration:1.4 
         delay:13.4 
        options:UIViewAnimationOptionCurveEaseInOut 
       animations:^{ 
        fishView.transform = CATransform3DGetAffineTransform(CATransform3DMakeRotation(-M_PI, 0.0, 1.0, 0.0)); 

       }completion:NULL]; 


/************************************* Animation 5 *******************************************/ 
[UIView animateWithDuration:13.8 
         delay:2.2 
        options:UIViewAnimationOptionCurveEaseInOut 
       animations:^{ 
        fishView.frame = CGRectMake(originalChildXpos, fishView.frame.origin.y, fishView.frame.size.width, fishView.frame.size.height); 
       }completion:NULL]; 

我想我在使用CATransform3DGetAffineTransform(CATransform3DMakeRotation())功能，第二次翻蓋旋轉錯過的東西.....

任何人都可以在這裏告訴我出路，並解釋我出錯的地方

我也想知道，而使用CATransform3D旋轉，做座標軸相對於視圖，應用變換改變或受到影響？ ？

CGFloat originalChildXpos = fishView.frame.origin.y; 
    CGAffineTransform currentTransform=fishView.transform; // step one add this 

    /************************************** Animation 1 **************************************************************/

         fishView.frame =CGRectMake(0, fishView.frame.origin.y, fishView.frame.size.width, fishView.frame.size.height);

用於變ü沒有在最初的X = Y那麼現在你的X成爲Ÿ 並在接下來的語句中，改變Y = Y所以沒有效果...
