不知道這個錯誤代碼意味着什麼：「蘋果LLVM編譯器3.1錯誤」，「鐺失敗，退出代碼254」Cocos2D，Xcode 4.3.3

Question

四處看看，我找不到任何滿意的答案，我的特定問題。在SO上發現了關於這個錯誤代碼的一些帖子，但是他們大多在談論編譯器有點符號和標籤沒有被分配的問題，所以這些問題在這裏似乎不適用。

在我的HelloWorldLayer.m文件中，我有一個方法將CCSprites添加到圖層並將它們移動到屏幕上的某些位置。該方法工作正常 - 精靈被初始化並正確動畫 - 當我移動每個精靈和單獨設置我的布爾值將，就像這樣：

[card1 moveToCard1Position]; 
[opponentCard1 moveToOpponentCard1Position]; 
[card2 moveToCard2Position]; 
[opponentCard2 moveToOpponentCard2Position]; 
[CCDelayTime actionWithDuration: kHoleCardTravelTime]; 

// BOOLs to determine if the card is in its proper place 
card1ReachedPosition = YES; 
card2ReachedPosition = YES; 
opponentCard1ReachedPosition = YES; 
opponentCard2ReachedPosition = YES; 

但我需要的布爾變量沒有被設置，直到動畫已實際完成實時。所以，當我使用CCSequence延遲的bool爲YES的設置後，才動畫已經完成，像這樣：

[self runAction:[CCSequence actions:[CCDelayTime actionWithDuration:0.0], 
      [card1 moveToCard1Position], 
      [opponentCard1 moveToOpponentCard1Position], 
      [card2 moveToHoleCard2Position], 
      [opponentCard2 moveToOpponentCard2Position], 
      [CCDelayTime actionWithDuration:kCardTravelTime], 
      card1ReachedPosition = YES, 
      card2ReachedPosition = YES, 
      opponentCard1ReachedPosition = YES, 
      opponentCard2ReachedPosition = YES, 
      nil]];  

我得到錯誤「退出代碼254失敗鐺」。完整的錯誤，我會在底部顯示徹底。我在我的HelloWorldLayer.m文件的其他地方使用了[self runAction：...]，但由於某些原因我無法弄清楚，只有這種方法會拋出254錯誤。我會做什麼錯？ TIA

Answer 1

CCSequence獲取從CCAction派生的類對象的列表。顯然card1ReachedPosition不是CCAction類的實例，它是一個BOOL。從代碼很難說，但[card1 moveToCard1Position]可能不會返回一個CCAction類的實例。

你想要做什麼（除了不重嵌套方法調用）是使用CCCallFunc或CCCallBlock操作分別爲你設置布爾值以將調用轉接到moveToXXX方法。
