Change the font size of UISearchBar

Question

How can I change the font size of UISearchBar ?

Answer 1

I wanted to use 'Roboto-Regular' as default font for all the uisearchbars in my project. I made an uisearchbar extension.

extension UISearchBar {
func addRobotoFontToSearchBar(targetSearchBar:UISearchBar?) -> UISearchBar
{
    let textFieldInsideSearchBar = targetSearchBar!.valueForKey("searchField") as! UITextField
    textFieldInsideSearchBar.font = UIFont(name: "Roboto-Regular", size: 15.0)

//UIBarButtons font in searchbar
let uiBarButtonAttributes: NSDictionary = [NSFontAttributeName: UIFont(name: "Roboto-Regular", size: 15.0)!] 
UIBarButtonItem.appearance().setTitleTextAttributes(uiBarButtonAttributes as? [String : AnyObject], forState: UIControlState.Normal)

    return targetSearchBar!
}
}

Usage:

self.sampleSearchBar.addRobotoFontToSearchBar(sampleSearchBar)
