如何更改導航欄標題顏色？

Question

我試圖這樣更改標題顏色，但沒有效果。

NSDictionary *navbarTitleTextAttributes = [NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor], NSForegroundColorAttributeName, nil];
[[UINavigationBar appearance] setTitleTextAttributes:navbarTitleTextAttributes];

導航欄樣式可能是黑色的問題？

self.navigationController.navigationBar.barStyle = UIBarStyleBlack;

Answer 1

使用UITextAttributeTextColor而不是NSForegroundColorAttributeName作為密鑰，它將起作用:)

Answer 2

嘗試這個 ：

self.navigationItem.title = @"The title";
self.navigationController.navigationBar.titleTextAttributes = [NSDictionary dictionaryWithObject:[UIColor redColor] forKey:NSForegroundColorAttributeName];

Answer 3

嘗試使用控制器的navigationBar的實例

UIFont* font = kRobotoMedium(21));
[controller.navigationController.navigationBar setTitleTextAttributes:@{NSForegroundColorAttributeName:[UIColor whiteColor],NSFontAttributeName:font}];
