Question

我想知道如何在使用UINavigationController时更改视图标题的字体大小..，提前致谢

Answer 1

您无法直接更改它。使用您想要的样式创建自定义UILabel或任何其他视图，并将其指定为self.navigationItem.titleView。

Answer 2

    self.title = @"";
    UILabel *myNavigationTitleLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 5, self.view.frame.size.width, 33)];
    myNavigationTitleLabel.textColor = [UIColor whiteColor];
    myNavigationTitleLabel.backgroundColor = [UIColor clearColor];
    myNavigationTitleLabel.text = @"my Custom title";
    myNavigationTitleLabel.textAlignment = UITextAlignmentCenter;
    myNavigationTitleLabel.font = [UIFont fontWithName:@"Arial" size:17];
    [self.navigationController.navigationBar addSubview:myNavigationTitleLabel];
    [myNavigationTitleLabel release];

请注意，如果您有横向界面方向，则需要为myNavigationTitleLabel设置新框架。

更改字体和标题...

+（void）setNavigationTitle：（NSString *）title ForNavigationItem：（UINavigationItem *）navigationItem { UIView * view = [[UIView alloc] initWithFrame：CGRectMake（0.0f， 0.0f，200.0f，44.0f）];
UILabel *titleLbl = [[UILabel alloc]
initWithFrame：CGRectMake（0.0f，6.0f，200.0f，30.0f）];
[titleLbl setFont:[UIFont fontWithName:@"BellCent NamNum BT"
尺寸：24.0]];
[titleLbl setBackgroundColor:[UIColor clearColor]];
[titleLbl setTextAlignment:UITextAlignmentCenter];

[titleLbl setTextColor:UIColorFromRedGreenBlue(35,134,192)];
[titleLbl setShadowColor:UIColorFromRedGreenBlue(186,186,186)];
[titleLbl setShadowOffset:CGSizeMake(1.0f, 1.0f)];

[titleLbl setText:title];

  [view addSubview:titleLbl];

[navigationItem setTitleView:view];
[titleLbl release];

 }
