Question

I have dynamically created view ,inside that dynamically created buttons.while clicking the buttons I have to get both view’s and button’s tag.
I have used the code as

-(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);

  }

some times the control goes to button press and some times to view touched.I have to get both tag at a time.
Thanks in advance

When you add a subview like so:

[numberView addSubview:numberButton];

numberButton becomes a subview of numberView; also numberView becomes the superview of numberButton. And you can access it through that property.

-(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);
}
