Removing view from its superview

I have added a few buttons to self.view. When the user clicks on one button, i will load another view (subView). My code where i am loading the subView is shown below

subView = [[UIView alloc] initWithFrame:CGRectMake(0,0,self.scrollView.contentSize.width, self.scrollView.contentSize.height)];
subView.tag=1;
// and then i add various other components to it

[self.view addSubview:subView]; // and finally add it to the view

When the user touches this view, i detect it and remove the view (i have already done the detection part).

This is how i am removing the view

UIView *v = [self.subView viewWithTag:1];
    v.hidden = YES;
    [v endEditing:YES];
 [v removeFromSuperview];

The view dissapears, but i can't click on the buttons or anything that was on the self.view. When i hold the mouse cursor on a button for awhile i could click it otherwise i can't. How can i solve this ?

I think your problem is that you do

[self.subView viewWithTag:1];

but the view you want to remove is "owned" by self.view so it should be

[self.view viewWithTag:1];

But if you have a reference to subView, why search it again? Why not immediately:

self.subView.hidden = YES;
[self.subView endEditing:YES];
[self.subView removeFromSuperview];

Btw you might want to look into your memory management, I see you alloc your subView but I don't see it being released, when the view is removed again. Maybe you do and you just don't show the code, in that case forget my comment.

Try removing the subview like this:

for (UIView *subView in self.view.subviews) {
    if (subView.tag == (int)yourSubViewTag) {

        [subView removeFromSuperview];
    }
}

Should this line:

UIView *v = [self.subView viewWithTag:1];

really be:

UIView *v = [self.view viewWithTag:1];

?
