title: UIViewAnimationOptionAllowUserInteraction not working
body: <p>the problem is this : i have the class <code>NKIngredient</code> which is a subclass of <code>UIImageView</code>. I've implemented the <code>touchesBegan/Moved/Ended</code> methods in it and set the <code>userInteractionEnabled</code> on <code>YES</code>. But the major problem is that when i animate my <code>NKIngredient</code> instance in a view controller i need the object can be touched during the animation. And this is impossible! 
  The interface of <code>NKIngredient</code> : </p>
  
  <pre><code>@protocol NKIngredientDelegate &lt;NSObject&gt;
  
  - (void)ingredientTouched;
  
  @end
  
  @interface NKIngredient : UIImageView {
      CGPoint touchStart;
  
  }
  
  @property (weak, nonatomic) id &lt;NKIngredientDelegate&gt; delegate;
  
  - (void)animate:(void (^)(void))animationBlock;
  
  @end
  </code></pre>
  
  <p>The implementation file : </p>
  
  <pre><code>@implementation NKIngredient
  
  - (id)initWithFrame:(CGRect)frame {
      self = [super initWithFrame:frame];
      if (self) {
          [self setUserInteractionEnabled:YES];
      }
      return self;
  }
  
  //Viene chiamato questo metodo se l'oggetto è disegnato come nib
  - (id)initWithCoder:(NSCoder *)aDecoder {
      NSLog(@"NKIngredient initWithCoder");
      if (self = [super initWithCoder:aDecoder]) {
          [self setUserInteractionEnabled:YES];
      }
      return self;
  }
  
  /*
  // Only override drawRect: if you perform custom drawing.
  // An empty implementation adversely affects performance during animation.
  - (void)drawRect:(CGRect)rect
  {
      // Drawing code
  }
  */
  
  - (BOOL)becomeFirstResponder {
      return YES;
  }
  
  - (void)animate:(void (^)(void))animationBlock {
      [UIView animateWithDuration:8.0 delay:0.0 options:UIViewAnimationOptionAllowAnimatedContent &amp; UIViewAnimationOptionAllowUserInteraction animations:animationBlock completion:^ (BOOL finished) {
          NSLog(@"Completed");
      }];
  }
  
  #pragma mark - Touch interaction
  
  - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
      //NSLog(@"Touches began");
      [_delegate ingredientTouched];
      touchStart = [[touches anyObject] locationInView:self];
      NSLog(@"Touched");
  }
  
  - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
      NSLog(@"Touches moved");
      CGPoint point = [[touches anyObject] locationInView:self];
      self.center = CGPointMake(self.center.x + point.x - touchStart.x, self.center.y + point.y - touchStart.y);
  }
  
  @end
  </code></pre>
  
  <p>And this is what i do in my view controller : </p>
  
  <pre><code>ingredient = [[NKIngredient alloc] initWithFrame:CGRectMake(20, -50, 34, 45)];
      [ingredient setImage:[UIImage imageNamed:@"liv1_Burro.png"]];
      [ingredient setUserInteractionEnabled:YES];
      [[self view] addSubview:ingredient];
  
  
      [ingredient animate:^ (void) {
          [ingredient setFrame:CGRectMake(20, 200, 34, 45)];
      }];
  </code></pre>
  
  <p>Some solution to get the touch even when the object is animating? Because when the <code>NKIngredient</code> is stationary the <code>touchesBegan/Moved/Ended</code> methods works.</p>
