可可触摸则hitTest withEvent可以识别UIView子类

Question

我有子视图的视图，这些子视图的UIView的子类，在本例中的子类被称为ESDcelda

- (id)initWithFrame:(CGRect)frame 
{ 
    self = [super initWithFrame:frame]; 
    if (self) { 
     UIImage *img = [UIImage imageNamed:@"lgrey091.gif"]; 
     [self setBackgroundColor:[UIColor colorWithPatternImage:img]]; 

     ESDcelda *cel1 = [[ESDcelda alloc] initWithTipo:1]; 
     [cel1 setFrame:CGRectMake(100, 100, cel1.frame.size.width, cel1.frame.size.height)]; 
     [self addSubview:cel1]; 

     cel1 = [[ESDcelda alloc] initWithTipo:2]; 
     [cel1 setFrame:CGRectMake(300, 100, cel1.frame.size.width, cel1.frame.size.height)]; 
     [self addSubview:cel1]; 
    } 
    return self; 
} 

现在我triyng知道什么样的UIView我指向与以下方法的touchEvents，但在日志指针“Vista”只识别自我类或UIView类，有任何方法来识别子类“celdaSel”？

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event 
{ 
    UITouch *touch = [[touches allObjects] objectAtIndex:0]; 

    [self perfTouch:touch]; 
} 

-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event 
{ 
    UITouch *touch = [[touches allObjects] objectAtIndex:0]; 

    [self perfTouch:touch]; 
} 

-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event 
{ 
    UITouch *touch = [[touches allObjects] objectAtIndex:0]; 

    [self perfTouch:touch]; 
} 

-(void)perfTouch:(UITouch *)touch 
{ 
    CGPoint punto = [touch locationInView:self]; 

    UIView *vista = (ESDcelda *)[self hitTest:punto withEvent:nil]; 

    if (![vista isKindOfClass:[self class]]) 
    { 
     celdaSel = (ESDcelda *)vista; 
     [celdaSel seleccion:YES]; 
    } 
    else 
    { 
     if (celdaSel != nil) 
     { 
      [celdaSel seleccion:NO]; 
     } 
    } 
}

解决，有

1. 在主视图中仅留下了interpects触摸，并且其中是它的代码的步骤。

v

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event 
{ 
    UITouch *touch = [[touches allObjects] objectAtIndex:0]; 

    [self perfTouch:touch]; 
} 

-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event 
{ 
    UITouch *touch = [[touches allObjects] objectAtIndex:0]; 

    [self perfTouch:touch]; 
} 

-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event 
{ 
    UITouch *touch = [[touches allObjects] objectAtIndex:0]; 

    [self perfTouch:touch]; 

    if (self.celdaSel != nil) 
    { 
     NSLog(@"%d",self.celdaSel.elemento); 
    } 
} 

-(void)perfTouch:(UITouch *)touch 
{ 
    CGPoint punto = [touch locationInView:self]; 

    [self hitTest:punto withEvent:nil]; 

} 

1. 在UIView子类称为ESDCelda我重写pointInside：withEvent方法来了解当前单点触摸是认为，“跨”是，让我知道变量如果触摸位于视图上，“seleccionada”指示视图是否突出显示，“conten”是指向superview的指针，“seleccion：”是突出显示其自身视图的方法。

v

-(BOOL)pointInside:(CGPoint)point withEvent:(UIEvent *)event 
{ 
    BOOL inter = [super pointInside:point withEvent:event]; 
    if (inter) 
    { 
     //NSLog(@"%i, %@", inter, self); 
     if (!self.selecionada) 
     { 
      [self seleccion:YES]; 
      if (self.conten.celdaSel != nil) 
       [self.conten.celdaSel seleccion:NO]; 
      [self.conten setCeldaSel:self]; 
     } 
    } 
    else 
    { 
     if (self.selecionada) 
     { 
      [self seleccion:NO]; 
      [self.conten setCeldaSel:nil]; 
     } 
    } 
    return inter; 
}
