在UIPopoverController中更改后退按钮，导航标题的颜色

Question

I have added the UIActivityViewController in the contentView of UIPopoverController . And trying to open Print Option which is navigating in UIPopoverController itself. I am getting that view

And I am getting the color of Title (Print Options / Printer) and back button is white , I want it to blue.this is only in case of UIPopoverController . Otherwise al is fine.

Please suggest !!!

Answer 1

For the Title use:

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

For the arrow and text of back button:

[self.navigationController.navigationBar setTintColor:[UIColor blueColor]];

And of course if you have an object of UIPopoverController you have to apply the styles from navigation bar:

popoverController.navigationBar.titleTextAttributes = self.navigationController.navigationBar.titleTextAttributes;

Answer 2

在该控制器的viewDidLoad方法中：

 for (UIView *subview in self.navigationController.navigationBar.subviews) [subview setTintColor:[UIColor blueColor]];
