Change UIBarButtonItem from UISearchBar

问题

I'd like to change the text font and color of the Cancel button inside the UISearchBar in iOS 8. I've tried the solutions for iOS 6 and 7 already and they don't seem to work.

回答1:

This was not the solution I was looking for, but it worked.

let cancelButtonAttributes: NSDictionary = [NSFontAttributeName: FONT_REGULAR_16!, NSForegroundColorAttributeName: COLOR_BLUE]
UIBarButtonItem.appearance().setTitleTextAttributes(cancelButtonAttributes, forState: UIControlState.Normal)

回答2:

What you are looking for is:

//The tintColor below will change the colour of the cancel button
searchBar.tintColor = UIColor.blueColor()

But these are also useful While we are on the subject:

searchBar.placeholder = "Placeholder"
//The barTintColor changes the colour of the flashing text indicator
searchBar.barTintColor = UIColor.redColor()
//This sets the cancel button to show up
searchBar.setShowsCancelButton(true, animated: true)
//This makes the searchBar become active 
searchBar.becomeFirstResponder()
