单击子项时如何一次获取父视图标签和子标签？

Question

我已经动态创建了视图，并在其中动态创建了按钮。单击按钮时，我必须同时获取视图和按钮的标签。我已经将代码用作

-(void)addButton
{
    for (int j=0; j<[defaultNumberAry count]; j++) {

    numberButton=[[UIButton alloc]initWithFrame:CGRectMake(n, 0, 40, 40)];
    n=n+42;
    [numberButton setBackgroundImage:[defaultNumberAry objectAtIndex:j] forState:UIControlStateNormal];
    numberButton.tag=j;
    [numberTagAry addObject:[NSString stringWithFormat:@"%d",j]];
    numberButton.userInteractionEnabled = YES;
    [numberButton addTarget:self action:@selector(pressed:) forControlEvents:UIControlEventTouchUpInside];
    numberButton.autoresizingMask = UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleBottomMargin | UIViewAutoresizingFlexibleWidth;
    [numberView addSubview:numberButton];

}
}
-(void)addView:(int)yv
{
n=22;
numberView=[[UIView alloc]initWithFrame:CGRectMake(300, yv, 400, 44)];
numberView.backgroundColor=[UIColor yellowColor];
numberView.tag=b;
b++;
numberView.autoresizingMask = UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleBottomMargin | UIViewAutoresizingFlexibleWidth;
UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(touched:)];
[tapGestureRecognizer setNumberOfTapsRequired:1];
[numberView addGestureRecognizer:tapGestureRecognizer];

}
-(void)pressed:(id)sender{
    UIButton *button = (UIButton *)sender;
    if(!button.selected){
        NSLog(@"selected btn tag:%d",button.tag);       
                       }
}
- (void) touched:(id)sender
{
    int v=((UIGestureRecognizer *)sender).view.tag;
    NSLog(@"view tag:::%d",v);

  }

有时控件要按下按钮，有些时候要查看触摸。我必须一次获得两个标签。提前致谢

当您添加子视图时，如下所示：

[numberView addSubview:numberButton];

numberButton成为子视图的numberView; 也numberView成为上海华盈的numberButton。您可以通过该属性访问它。

-(void)pressed:(id)sender{
    UIButton *pressedButton = (UIButton *)sender;
    UIView *superViewOfPressedButton = pressedButton.superview;
    NSLog(@"Tag of button:%i Tag of pressed button's button view is %i",pressedButton.tag,superViewOfPressedButton.tag);
}
