Change UISearchBar textColor not working (5 answers)

Closed 10 months ago.

I'm using a GMSAutocompleteViewController and want to change the textColor in the searchBar but can't find a way to do it, I managed to change the some colors but not the searchBar text.

I've tried following code but the color won't change:

        acController.searchBarController?.searchBar.tintColor = UIColor.whiteColor()
        acController.searchBarController?.searchBar.textColor = UIColor.whiteColor()

        acController.searchBarController?.searchBar.textField.textColor = UIColor.whiteColor()
        acController.searchBarController?.searchBar.textField.tintColor = UIColor.whiteColor()
        acController.searchBarController?.searchBar.textField.backgroundColor = UIColor.whiteColor()

        acController.searchDisplayController?.searchBar.setTextColor(UIColor.whiteColor())
        acController.searchDisplayController?.searchBar.tintColor = UIColor.whiteColor()

        // changes the color of the sugested places
        acController.primaryTextColor = UIColor.whiteColor()
        acController.secondaryTextColor = UIColor.whiteColor()

For those who are looking for Swift 4 version, following code worked for me in Swift 4 (Xcode 9.4 & iOS 11)

UITextField.appearance(whenContainedInInstancesOf: [UISearchBar.self]).defaultTextAttributes = [NSAttributedStringKey.foregroundColor.rawValue: UIColor.white]
