touchesmoved leave frame

Question

touchesmovedが現在選択されているボタンのフレームを離れるときに、どのボタンを強調表示しないように設定できるかを調べようとしています。以下のコードを参照してください。以下のコードでは、3つのボタンのいずれかを個別に押してスワイプすることができます。私が抱えている問題は、ボタンがスウィープされたとき、例えばtouchesmovedを使用してボタンがアクションを呼び出すときですが、スワイプがボタンフレームを離れるときにボタンが戻らないように戻すことは決してありません。事前に

おかげで、

OK、私は前にこの同じ問題を扱ってきました知っています。私はまた、コード内の自分のコメントでそれへの参照を参照してください。私はシミュレートされたボタンを処理するために書いた非常に古いコードの塊を添付しました。多分これを見て助けてくれるでしょう：

typedef struct { 
      BOOL enabled; 
      BOOL isActivated; 
      NSTimeInterval activatedStartTime; 
      NSTimeInterval holdTime; 
      CGRect frame; 
      UIImageView *glowImage; 
      BOOL processPending; 
      SEL callWhenTouched; 
      } SIM_BUTTON;

    { 
    int fingers = [touches count]; 
    UITouch *touch; 
    CGPoint touchPoint; 
    int i, j; 

    for (i=0; i<fingers; i++) 
     { 
     touch = [[touches allObjects] objectAtIndex:i]; 
     touchPoint = [touch locationInView:self.view]; 


     for (j=0; j<SIM_BUTTON_COUNT; j++) 
      { 
      if (simButton[j].enabled && CGRectContainsPoint(simButton[j].frame, touchPoint)) 
       { 
       simButton[j].isActivated=YES; 
       simButton[j].activatedStartTime = [NSDate timeIntervalSinceReferenceDate]; 
       simButton[j].processPending = YES; 
       }

     } 
    }
