UI导航栏标题

我试图使用 UILabel 来替换 UINavigationBar 上的标题，代码如下：

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];

问题是，如何删除栏的原始标题？我没有声明任何 self.title = @"title"，但它总是显示在那里：

如果我这样做 self.title = nil，那么一切都消失了...如何从导航栏中消除这个神秘的标题并只使用我创建的 UILabel。

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:

enter image description here

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.

你为什么不直接做 self.title = @"" 呢？

编辑：试试这个？

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];

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];

使用 self.navigationItem.titleView = nav_title; 而不是将标签添加为子视图。

使用这个：

  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..!
