Can't remove a label programmatically - ios

Question

I am printing a label programmatically but I can't remove it from the screen. I have tried removeFromSuperview and lbl1.hidden = YES; and lbl1= nil; but non of them work. It stays on the screen all the time while I can see in the debug it pass from ELSE as in the code below.
Where would be my problem?
-(void)reloadData
lbl1 = [[UILabel alloc] initWithFrame:CGRectMake(320, 530, 550, 200)];
if (result1 > result2 && al == YES)
{
lbl1.userInteractionEnabled = YES;
lbl1.text = #" Warning!! ";
lbl1.tag = 30;
lbl1.font = [UIFont fontWithName:#"Helvetica" size:18.0];
lbl1.textColor = [UIColor redColor];
lbl1.backgroundColor = [UIColor clearColor];
lbl1.lineBreakMode = NSLineBreakByWordWrapping;
lbl1.numberOfLines = 2;
[self addSubview:lbl1];
[lbl1 release];
}
else{
//Non of them is removing the label.
[lbl1 removeFromSuperview];
lbl1= nil;
lbl1.hidden = YES;
}

Answer 1

Every time you go into reloadData, you are creating a new label, so if you go into reload and jump to the else, you are creating a label, and then removing it.
You need to save that label as an instance variable and remove it/add it in your reloadData.
#property(nonatomic, strong) UILabel *lbl1;
And in your code, do this only ONCE:
self.lbl1 = [[[UILabel alloc] initWithFrame:CGRectMake(320, 530, 550, 200)] autorelease];
And in your reloadData do:
-(void)reloadData
lbl1 = [[UILabel alloc] initWithFrame:CGRectMake(320, 530, 550, 200)];
if (result1 > result2 && al == YES)
{
self.lbl1.userInteractionEnabled = YES;
//Etc...
}
else{
[self.lbl1 removeFromSuperview];
}

Try like this:
-(void)reloadData
if(!lbl1)
lbl1 = [[UILabel alloc] initWithFrame:CGRectMake(320, 530, 550, 200)];
if (result1 > result2 && al == YES)
{
lbl1.userInteractionEnabled = YES;
lbl1.text = #" Warning!! ";
lbl1.tag = 30;
lbl1.font = [UIFont fontWithName:#"Helvetica" size:18.0];
lbl1.textColor = [UIColor redColor];
lbl1.backgroundColor = [UIColor clearColor];
lbl1.lineBreakMode = NSLineBreakByWordWrapping;
lbl1.numberOfLines = 2;
[self addSubview:lbl1];
[lbl1 release];
}
else{
//Non of them is removing the label.
[lbl1 removeFromSuperview];
lbl1= nil;
lbl1.hidden = YES;
}

Try to remove like this....
if (result1 > result2 && al == YES)
{
lbl1.userInteractionEnabled = YES;
lbl1.text = #" Warning!! ";
lbl1.tag = 30;
lbl1.font = [UIFont fontWithName:#"Helvetica" size:18.0];
lbl1.textColor = [UIColor redColor];
lbl1.backgroundColor = [UIColor clearColor];
lbl1.lineBreakMode = NSLineBreakByWordWrapping;
lbl1.numberOfLines = 2;
[self addSubview:lbl1];
[lbl1 release];
}
else{
//Non of them is removing the label.
[[self.view viewWithTag:30] removeFromSuperview];
lbl1= nil;
lbl1.hidden = YES;
}
