问题 I was already able to set the text and icon colors for my tab bar items as desired. White for not active, blue for active. However, I still run into one issue: When a popover or alert view is shown, the tab bar item icon is greyed out: Is there any possibility to keep the blue color for this state? Thanks for your help. EDIT I'm sorry, but my question is not a duplicate. I already do all these things: self.tabBar.tintColor = COLOR_CORPORATE_BLUE; [[UITabBarItem appearance]

To speed it up and to get to the real end I use estimatedHeightForRowAtIndexPath and I return for the first 8

问题 No matter what I seem to try, in the email screen that comes up when a user chooses to email a link (it's a MFMailComposeViewController ) the buttons are always the default blue. I have this in my AppDelegate: [[UINavigationBar appearance] setBarTintColor:[UIColor colorWithRed:0.000 green:156/255.0 blue:51/255.0 alpha:1]]; [[UINavigationBar appearance] setTintColor:[UIColor whiteColor]]; [[UINavigationBar appearance] setTitleTextAttributes:@{ NSForegroundColorAttributeName: [UIColor
