touchesmoved quitter frame

Question

J'essaie de comprendre comment je peux définir un bouton pour ne pas être mis en surbrillance lorsque touché touches quitte le cadre du bouton sélectionné en cours. Voir le code ci-dessous. Le code ci-dessous devrait permettre à l'un des trois boutons d'être pressé individuellement et swipped. Le problème que je rencontre est que lorsque les boutons ont été déplacés, par exemple en utilisant les touches, les boutons appellent les actions, mais ne remettent jamais les boutons en surbrillance lorsque le balayage quitte le cadre du bouton.

Merci à l'avance,

OK, je sais que je l'ai traité ce même problème auparavant. Je vois aussi une référence à cela dans mes propres commentaires dans le code. J'ai joint un morceau de code très ancien que j'ai écrit pour gérer des boutons simulés (similaire à ce que vous faites). Peut-être que regarder à travers cela aidera:

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



- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event 
    { 
    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; 
       } 
      } 
     } 
    } 



- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event 
    { 
    int fingers = [touches count]; 
    UITouch *touch; 
    CGPoint touchPoint; 
    CGPoint previousTouchPoint; 
    int i, j; 

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

     for (j=0; j<SIM_BUTTON_COUNT; j++) 
      { 
      if (simButton[j].enabled && simButton[j].isActivated && CGRectContainsPoint(simButton[j].frame, touchPoint) && CGRectContainsPoint(simButton[j].frame, previousTouchPoint)) 
       {

       simButton[j].activatedStartTime = [NSDate timeIntervalSinceReferenceDate]; 
       simButton[j].isActivated=YES; 
       } 
      else 
      if (simButton[j].enabled && simButton[j].isActivated && !CGRectContainsPoint(simButton[j].frame, touchPoint) && CGRectContainsPoint(simButton[j].frame, previousTouchPoint)) 
       { 
       simButton[j].isActivated=NO; 
       simButton[j].activatedStartTime = (NSTimeInterval)0.0;

       } 

      // 
      // If the user touched the SCAN button and then slid their finger off of the SCAN button 
      // 
      if (scannerActive==YES && simButton[RIGHT_SCAN_BUTTON].isActivated==NO && CGRectContainsPoint(simButton[RIGHT_SCAN_BUTTON].frame, previousTouchPoint)) 
       { 
       phraseMode = EXTERNAL_SCAN_PHRASES;  // Default 
       } 
      } 
     } 
    }
