swift UITabBarItem修改字体颜色和图标颜色

storyboard创建的选项卡，图片颜色固定，字体颜色固定。可以说完全没法用，查阅了好久的api和资料才找到修改的办法。

将UITabBarItem连线到FirstViewController

代码如下：

//
//  FirstViewController.swift
//  demo

import UIKit

class FirstViewController: UIViewController {
    @IBOutlet weak var tab1: UITabBarItem!

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view,typically from a nib.
        //这里修改图片颜色，使得图片和原图颜色一致
        tab1.image=UIImage(named: "tab1")?.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal);
        //这里修改字体颜色
        var attributes =  [NSForegroundColorAttributeName: UIColor(red: 220.0/255.0,green: 104.0/255.0,blue: 1.0/255.0,alpha: 1.0),NSFontAttributeName: UIFont(name: "Heiti SC",size: 24.0)!]
        tab1.setTitleTextAttributes(attributes,forState: UIControlState.Selected)
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


}
