如何更改导航栏的字体？

Answer 1

尝试使用titleTextAttributes属性...

的属性

  let attributesDictionary = [NSFontAttributeName: UIFont(name: "your font name", size: 24)!, NSForegroundColorAttributeName : UIColor.whiteColor()]
  UINavigationBar.appearance().titleTextAttributes = attributesDictionary

Answer 2

试试这段代码，这是用Obj-C编写的，但你可以从这里得到想法

[[UINavigationBar appearance] setTitleTextAttributes: [NSDictionary dictionaryWithObjectsAndKeys:
                                                           [UIColor colorWithRed:245.0/255.0 green:245.0/255.0 blue:245.0/255.0 alpha:1.0], NSForegroundColorAttributeName,
                                                           [UIFont fontWithName:@"HelveticaNeue-CondensedBlack" size:21.0], NSFontAttributeName, nil]];

Answer 4

如果您想更改所有导航栏的字体，可以在OC中执行此操作：

[[UINavigationBar appearance] setTitleTextAttributes:
    @{NSFontAttributeName:[UIFont systemFontOfSize:22], // font size
     NSForegroundColorAttributeName:[UIColor yellowColor], // foreground color
     NSBackgroundColorAttributeName:[UIColor blackColor]}]; // background color

这在Swift：

UINavigationBar.appearance().titleTextAttributes = 
    [NSFontAttributeName:UIFont.systemFontOfSize(22), // font size
     NSBackgroundColorAttributeName:UIColor.yellowColor(), // background color
     NSForegroundColorAttributeName:UIColor.blackColor()] // foreground color

但是如果你只是想改变一些指定的视图控制器，你可以在OC中这样做：

[self.navigationController.navigationBar setTitleTextAttributes:
    @{NSFontAttributeName:[UIFont systemFontOfSize:22], 
      NSForegroundColorAttributeName:[UIColor yellowColor], 
      NSBackgroundColorAttributeName:[UIColor blackColor]}];

这在Swift：

self.navigationController?.navigationBar.titleTextAttributes =
        [NSFontAttributeName:UIFont.systemFontOfSize(22),
            NSForegroundColorAttributeName:UIColor.yellowColor(),
            NSBackgroundColorAttributeName:UIColor.blackColor()]

希望这些有用。
