How to change UISearchBar Font Size & Color?

问题

I've google fews hours how to change my UISearchBar font size & color, but I cannot any documents related to it.

This is what I've done so far on swift 4:

 searchBar = UISearchBar(frame: CGRect(x: 0, y: 0, width: view.frame.width - (menuImage.frame.width + iconImage.frame.width + 55), height: 30))
 searchBar.placeholder = "SEARCH BAR"
 searchBar.tintColor = UIColor.gray
 searchBar.delegate = self
 searchBar.font = [UIFont fontWithName:@"Oswald" size:11];

but it gave me an error.

Could you tell me how can I change the UISearchBar font size & color?

Please help!!!

To change text and placeholder searchbar:

// SearchBar text
let textFieldInsideUISearchBar = searchBar.value(forKey: "searchField") as? UITextField
textFieldInsideUISearchBar?.textColor = UIColor.red
textFieldInsideUISearchBar?.font = textFieldInsideUISearchBar?.font?.withSize(12)

// SearchBar placeholder
let textFieldInsideUISearchBarLabel = textFieldInsideUISearchBar!.value(forKey: "placeholderLabel") as? UILabel
textFieldInsideUISearchBarLabel?.textColor = UIColor.red

Here's how you can change the font and text color on latest Swift:

let attributes = [NSAttributedString.Key.font: UIFont.boldSystemFont(15), NSAttributedString.Key.foregroundColor: UIColor.gray]
UITextField.appearance(whenContainedInInstancesOf: [UISearchBar.self]).defaultTextAttributes = attributes

You can use the Appearance proxies to style the UISearchBar text and placeholder:

Change placeholder:

let placeholderAppearance = UILabel.appearance(whenContainedInInstancesOf: [UISearchBar.self])
placeholderAppearance.font = UIFont(name: "Baskerville", size: 14)
placeholderAppearance.textColor = .red

Change search text:

let searchTextAppearance = UITextField.appearance(whenContainedInInstancesOf: [UISearchBar.self])
searchTextAppearance.font = UIFont(name: "Baskerville", size: 14)
searchTextAppearance.textColor = .green

searchBarOutlet.setScopeBarButtonTitleTextAttributes([NSForegroundColorAttributeName: UIColor.whiteColor()], forState:UIControlState.Normal)
