How to manage subviews added in a UIView?

I have a problem in clearing my view, For a particular case I have been adding user names as label into my view, I may have multiple user based on situation, now my problem is, For one case I want to clear the view without popping it, I am not sure how to remove those added labels, I have an idea I can set tag for each label, and I can clear using that later. Any other efficient way is there in this particular case.

Hope my question is clear thanks.

Call below method and pass the "UIWebView" object as argument:

+(void)removeAllSubViews:(id)pObj
{
    NSArray *Array = [pObj subviews];
    for(int index = 0; index < [Array count]; index++)
    {
        [[Array objectAtIndex:index] removeFromSuperview];
    }
}

You can also check object like this if you want for any particular object:

if(view isKindOfClass:[UILabel class]) {
    //do whatever you want to do
}

Cheers!

Try this:

for (UIView *v in [self.relatedView subviews])
{
    [v removeFromSuperview];
}

    {
        [viewSub removeFromSuperview];

You can do in the following way

for (UIView *view in [self.view subviews])
{
    if ([view isKindOfClass:[UILabel class]])
    {
        [view removeFromSuperview];
    }
}

Hope you are asking about this.

You can remove all subviews like this:

for (UIView *subView in [view subviews])
    [subView removeFromSuperview];

Or if you want to access a particular view with tag value of n,

UIView *subview = [view viewWithTag:n]
