UINavigationBar title - iphone

Question

I am trying to use a UILabel to replace the title at the UINavigationBar, the code is as follows:
UINavigationBar *bar = [self.navigationController navigationBar];
[bar setBackgroundColor:[UIColor blackColor]];
UILabel * nav_title = [[UILabel alloc] initWithFrame:CGRectMake(80, 2, 220, 25)];
nav_title.font = [UIFont fontWithName:#"Arial-BoldMT" size:18];
nav_title.textColor = [UIColor whiteColor];
nav_title.adjustsFontSizeToFitWidth = YES;
nav_title.text = title;
nav_title.backgroundColor = [UIColor clearColor];
[bar addSubview:nav_title];
[nav_title release];
The problem is that, how do I remove the original title of the bar? I didn't declare any self.title = #"title", but it always shows it there:
If I do self.title = nil, then everything is gone... How do eliminate this mysterious title from the navbar and just use the UILabel I created.

Answer 1

Why don't you just do self.title = #""?
EDIT: Try this?
UINavigationBar *bar = [self.navigationController navigationBar];
[bar setBackgroundColor:[UIColor blackColor]];
UILabel * nav_title = [[UILabel alloc] initWithFrame:CGRectMake(80, 2, 220, 25)];
nav_title.font = [UIFont fontWithName:#"Arial-BoldMT" size:18];
nav_title.textColor = [UIColor whiteColor];
nav_title.adjustsFontSizeToFitWidth = YES;
nav_title.text = title;
self.title = #"";
nav_title.backgroundColor = [UIColor clearColor];
[bar addSubview:nav_title];
[nav_title release];

Answer 2

Use self.navigationItem.titleView = nav_title; instead of adding your label as a subview.

Answer 3

Use this:
UILabel *label = [[UILabel alloc]init];
[label setBackgroundColor:[UIColor clearColor]];
[label setTextColor:[UIColor whiteColor]];
[label setText:self.title];
label.adjustsFontSizeToFitWidth=YES;
label.lineBreakMode=UILineBreakModeWordWrap;
label.numberOfLines=0;
[label setFont:[UIFont boldSystemFontOfSize:16.0]];
[self.navigationController.navigationBar.topItem setTitleView:label];
[label release];
Hope this will help u..!
