更改UINavigationBar字体属性？

• 21

  在iOS8 swift中，使用以下代码设置字体：

  var navigationBarAppearance = UINavigationBar.appearance()
  let font = UIFont(name: "Open Sans", size: 17)
  if let font = font {
      navigationBarAppearance.titleTextAttributes = [NSFontAttributeName: font, NSForegroundColorAttributeName: UIColor.whiteColor()]
  }

  （使用新的iOS 5.0 Appearance API无法实现） .

  Edit:

  iOS> = 5.0：

  设置导航栏的 Headers 文本属性：

  // Customize the title text for *all* UINavigationBars
  NSDictionary *settings = @{
      UITextAttributeFont                 :  [UIFont fontWithName:@"YOURFONTNAME" size:20.0],
      UITextAttributeTextColor            :  [UIColor whiteColor],
      UITextAttributeTextShadowColor      :  [UIColor clearColor],
      UITextAttributeTextShadowOffset     :  [NSValue valueWithUIOffset:UIOffsetZero]};
  
  [[UINavigationBar appearance] setTitleTextAttributes:settings];
  

  iOS <5.0

  UINavigationItem没有名为label之类的属性，只有titleView . 您只能通过将自定义标签设置为此 Headers 视图来设置字体您可以使用以下代码:(如建议here）

  UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 200, 44)];
  label.font = [UIFont fontWithName:@"YOURFONTNAME" size:20.0];
  label.shadowColor = [UIColor clearColor];
  label.textColor =[UIColor whiteColor];
  label.text = self.title;  
  self.navigationItem.titleView = label;      
  [label release];

  把它放在你的app代表中

  - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

  [[UINavigationBar appearance] setTitleTextAttributes:
  [NSDictionary dictionaryWithObjectsAndKeys:
  [UIColor colorWithRed:255.0/255.0 green:255.0/255.0 blue:255.0/255.0 alpha:1.0], 
  UITextAttributeTextColor, 
  [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.8], 
  UITextAttributeTextShadowColor, 
  [NSValue valueWithUIOffset:UIOffsetMake(0, -1)], 
  UITextAttributeTextShadowOffset, 
  [UIFont fontWithName:@"STHeitiSC-Light" size:0.0], 
  UITextAttributeFont, nil]];

  从iOS 5开始，我们必须使用titleTextAttribute Dictionary（UInavigation控制器类引用中的预定义字典）设置 Headers 文本颜色和导航栏的字体 .

  [[UINavigationBar appearance] setTitleTextAttributes: 
      [NSDictionary dictionaryWithObjectsAndKeys: 
          [UIColor blackColor], NSForegroundColorAttributeName, 
             [UIFont fontWithName:@"ArialMT" size:16.0], NSFontAttributeName,nil]];
  

  以下教程是UIElements自定义的最佳教程，如UInavigation bar，UIsegmented control，UITabBar . 这可能对您有所帮助

  不要忘记将字体添加到目标 .

  我做了一切关于字体的事情我无法加载它，实际上字体不是我的目标成员 .

  因此，在添加的自定义字体上也检查目标成员身份 .

  以下链接将帮助您 . 这取决于您希望在应用程序的任何位置在当前viewController的导航栏上设置字体属性的位置

  你可以在这里找到很好的教程％http://www.appcoda.com/customize-navigation-status-bar-ios-7/?utm_campaign=iOS_Dev_Weekly_Issue_118&utm_medium=email&utm_source=iOS%2BDev%2BWeekly

  基本思想是创建NSDictionary实例并用您想要的字体和其他属性填充它 . 我完成了这个解决方案：

  在[super viewDidLoad]之后的-viewDidLoad控制器方法中放入以下行：

  UIColor *color = [UIColor redColor];
  NSShadow *shadow = [NSShadow new];
  UIFont *font = [UIFont fontWithName:@"EnterYourFontName" size:20.0]
  shadow.shadowColor = [UIColor greenColor];
  shadow.shadowBlurRadius = 2;
  shadow.shadowOffset = CGSizeMake(1.0f, 1.0f);
  
  //fill this dictionary with text attributes
  NSMutableDictionary *topBarTextAttributes = [NSMutableDictionary new];
      //ios 7
  topBarTextAttributes[NSForegroundColorAttributeName] = color;
      //ios 6
  topBarTextAttributes[UITextAttributeTextColor] = color;
      //ios 6
  topBarTextAttributes[UITextAttributeTextShadowOffset] = [NSValue valueWithCGSize:shadow.shadowOffset];
  topBarTextAttributes[UITextAttributeTextShadowColor] = shadow.shadowColor;
      //ios 7
  topBarTextAttributes[NSShadowAttributeName] = shadow;
      //ios 6
  topBarTextAttributes[UITextAttributeFont]   = font;
      //ios 7
  topBarTextAttributes[NSFontAttributeName]   = font;
  
  //for all the controllers uncomment this line
  //    [[UINavigationBar appearance]setTitleTextAttributes:topBarTextAttributes];
  
  //for current controller uncoment this line
  //    self.navigationController.navigationBar.titleTextAttributes = topBarTextAttributes;
