iOS 7导航栏文本和箭头颜色

Question

我想将导航栏的背景设置为黑色，并将其中的所有颜色设置为白色。

因此，我使用了以下代码：

[[UINavigationBar appearance] setTitleTextAttributes:

     [NSDictionary dictionaryWithObjectsAndKeys:

      [UIColor whiteColor],

      NSForegroundColorAttributeName,

      [UIColor whiteColor],

      NSForegroundColorAttributeName,

      [NSValue valueWithUIOffset:UIOffsetMake(0, -1)],

      NSForegroundColorAttributeName,

      [UIFont fontWithName:@"Arial-Bold" size:0.0],

      NSFontAttributeName,

      nil]];

但是后退按钮的文字颜色，箭头和方向键仍为默认蓝色。

如何更改下图所示的颜色？

Answer 1

UINavigationBar从iOS 7开始，某些属性的行为已更改。您可以在下面显示的图像中看到：我想与您分享两个美丽的链接。有关更多详细信息，您可以通过以下链接：iOS 7 UI过渡指南。如何为iOS更新您的应用程序7。苹果文档的barTintColor说：除非您将半透明属性设置为NO，否则默认情况下此颜色为半透明。样例代码：self.navigationController.navigationBar.barTintColor = [UIColor blackColor];self.navigationController.navigationBar.tintColor = [UIColor whiteColor];[self.navigationController.navigationBar  setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor whiteColor]}];self.navigationController.navigationBar.translucent = NO;

这花了我大约半天时间才弄清楚，但这对我有用。在用于初始化navigationController的rootViewController中，将以下代码放入viewDidAppear方法中：//set bar color[self.navigationController.navigationBar setBarTintColor:[UIColor colorWithRed:85.0/255.0 green:143.0/255.0 blue:220.0/255.0 alpha:1.0]];//optional, i don't want my bar to be translucent[self.navigationController.navigationBar setTranslucent:NO];//set title and title color[self.navigationItem setTitle:@"Title"];[self.navigationController.navigationBar setTitleTextAttributes:[NSDictionary dictionaryWithObject:[UIColor whiteColor] forKey:UITextAttributeTextColor]];//set back button color[[UIBarButtonItem appearanceWhenContainedIn:[UINavigationBar class], nil] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor], UITextAttributeTextColor,nil] forState:UIControlStateNormal];//set back button arrow color[self.navigationController.navigationBar setTintColor:[UIColor whiteColor]];

Swift3，iOS 10要全局分配颜色，请在AppDelegate中didFinishLaunchingWithOptions：let textAttributes = [NSForegroundColorAttributeName:UIColor.white]UINavigationBar.appearance().titleTextAttributes = textAttributesSwift 4，iOS 11let textAttributes = [NSAttributedStringKey.foregroundColor:UIColor.white]UINavigationBar.appearance().titleTextAttributes = textAttributes
