如何将 UIView 的标签推送到方法选择器

Question

我有 11 个 UIView 上每个都设置了一个手势识别器。这个UIView在可变数组中，每个都有一个标签。如何将 UIView 的标签推送到方法选择器？

viewIcone.userInteractionEnabled = YES;
viewIcone.tag = index;    
UITapGestureRecognizer * tap = [[UITapGestureRecognizer alloc]initWithTarget:self    action:@selector(touchUp:)];
tap.delegate = self;
[viewIcone addGestureRecognizer:tap];
[self.arrayMutabile insertObject:viewIcone atIndex:index];
[self addSubview:viewIcone];

方法选择器的实现是：

-(void) touchUp: (UITapGestureRecognizer *) gestureRecognizer{
   NSInteger tag = [self.arrayMutabile indexOfObject:self.viewIcone];
   NSLog(@"the tag is %d", tag);
}

我总是留下10个。错在哪里？提前致谢

UITapGestureRecognizer 有一个视图属性，它继承自其父级：

http://developer.apple.com/library/ios/#documentation/uikit/reference/UIGestureRecognizer_Class/Reference/Reference.html#//apple_ref/occ/cl/UIGestureRecognizer

The view the gesture recognizer is attached to. (read-only)
@property(nonatomic, readonly) UIView *view
Discussion
You attach (or add) a gesture recognizer to a UIView object using the addGestureRecognizer: method.
Availability
Available in iOS 3.2 and later.
Declared In
UIGestureRecognizer.h

这将是点击的视图，您可以从那里检索标签。
