I create a message when a process starts (BOOL YES) and I am trying to make it go away when it ends (BOOL NO), debugging shows me stepping through the whole function both in the beginning and end, however the message is still there.

Where am I going wrong? Thank you in advance

-(void) loadStillLoadingMessage:(BOOL)yesNo{
CGRect screenBound = [[UIScreen mainScreen] bounds];
CGSize screenSize = screenBound.size;
CGFloat screenWidth = screenSize.width;
CGFloat screenHeight = screenSize.height;
UILabel *loading = [[[UILabel alloc]initWithFrame:CGRectMake((screenWidth/2)-75,(screenHeight)-140,300,40)]autorelease];

loading.text = @"still loading";
loading.backgroundColor = [UIColor clearColor];
loading.textColor = [UIColor blueColor];
loadingLabel = loading;
[self.view addSubview:loadingLabel];
[loadingLabel setHidden:YES];
if (yesNo == YES) {
    [loadingLabel setHidden:NO];
}else if (yesNo ==NO){
    [loadingLabel setHidden:YES];
}

This method is creating a UIView whenever it is called. So the UIView you create and show on the first time is different to the UIView you create, show and then hide the second time. You need to look at instance variables (declaring a variable in the header file).
