黑色導航欄標題顏色可以更改嗎？

Question

我navigationBar是黑色的：

self.navigationController.navigationBar.barStyle = UIBarStyleBlack; 

但標題不能改變文字顏色，它有沒有效果，爲什麼呢？

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

Answer 1

嘗試使用此代碼：

NSDictionary *navbarTitleTextAttributes = [NSDictionary dictionaryWithObjectsAndKeys: 
              [UIColor whiteColor],UITextAttributeTextColor, 
              [UIColor blackColor], UITextAttributeTextShadowColor, 
              [NSValue valueWithUIOffset:UIOffsetMake(-1, 0)], UITextAttributeTextShadowOffset, nil]; 

[[UINavigationBar appearance] setTitleTextAttributes:navbarTitleTextAttributes]; 

Answer 2

試一下這個code.You可以很容易地改變你的標題顏色:)

self.navigationController.navigationBar.tintColor = White; 
self.navigationController.navigationBarHidden=NO; 
self.navigationItem.title = @"yourTitle"; 
[self.navigationController.navigationBar setTitleTextAttributes: 
@{NSForegroundColorAttributeName:White}]; 
self.navigationController.navigationBar.barTintColor = [UIColor blackColor]; 

Answer 3

[[UINavigationBar appearance] setTitleTextAttributes:@{NSFontAttributeName:[UIFont fontWithName:kBoldFontName size:16],NSForegroundColorAttributeName:[UIColor blueColor]}]; 

這是爲我工作的罰款請嘗試一次。

Answer 4

我嘗試下面的代碼，它正在fine.I我使用Xcode中8和iOS 10.2

self.navigationController.navigationBar.barStyle = UIBarStyleBlack; 

self.navigationItem.title = @"your Title here"; 

[self.navigationController.navigationBar setTitleTextAttributes: 
    @{NSForegroundColorAttributeName:[UIColor greenColor]}]; 

self.navigationController.navigationBar.barTintColor = [UIColor lightGrayColor];
