How to customize iOS tab icon colors (2 ways)

TabViewController.swift

override func viewDidLoad() {
    super.viewDidLoad()
    //change text under icon
    UITabBarItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.init(netHex: 0x000000)], forState: .Normal)
    UITabBarItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.init(netHex: 0xffffff)], forState: .Selected)
    
    //store every image in a variable
    let homeUnselectedImage: UIImage = UIImage(named: "home_grey")!.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
    let homeSelectedImage: UIImage = UIImage(named: "home_white")!.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
    
    let userUnselectedImage: UIImage = UIImage(named: "user_grey")!.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
    let userSelectedImage: UIImage = UIImage(named: "user_white")!.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
    
    let globeUnselectedImage: UIImage = UIImage(named: "globe_grey")!.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
    let globeSelectedImage: UIImage = UIImage(named: "globe_white")!.imageWithRenderingMode(UIImageRenderingMode.AlwaysOriginal)
    
    //use that variable for each icon
    tabBar.items![0].image = homeUnselectedImage
    tabBar.items![0].selectedImage = homeSelectedImage
    
    tabBar.items![1].image = globeUnselectedImage
    tabBar.items![1].selectedImage = globeSelectedImage
    
    tabBar.items![2].image = userUnselectedImage
    tabBar.items![2].selectedImage = userSelectedImage

}

TabViewController2.swift

override func viewDidLoad() {
    super.viewDidLoad()
    
    //Setting the text color under each tab bar item
    UITabBarItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.blackColor()], forState:.Normal)
    UITabBarItem.appearance().setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.whiteColor()], forState:.Selected)
    
    //setting tab bar items colors when NOT selected
    for item in self.tabBar.items as [UITabBarItem]! {
        if let image = item.image {
            item.image = image.imageWithColor(UIColor.blackColor()).imageWithRenderingMode(.AlwaysOriginal)
        }
    }

    //setting tab bar items colors when selected
    UITabBar.appearance().tintColor = UIColor.whiteColor()

}

UIImageExtension.swift

//This part is not my code, I took it from : http://stackoverflow.com/a/24545102/3050466
//You will need this code to be able to do the second way (TabViewController2.swift)

extension UIImage {
  func imageWithColor(color1: UIColor) -> UIImage {
      UIGraphicsBeginImageContextWithOptions(self.size, false, self.scale)
      color1.setFill()
      
      let context = UIGraphicsGetCurrentContext() as CGContextRef!
      CGContextTranslateCTM(context, 0, self.size.height)
      CGContextScaleCTM(context, 1.0, -1.0);
      CGContextSetBlendMode(context, CGBlendMode.Normal)
      
      let rect = CGRectMake(0, 0, self.size.width, self.size.height) as CGRect
      CGContextClipToMask(context, rect, self.CGImage)
      CGContextFillRect(context, rect)
      
      let newImage = UIGraphicsGetImageFromCurrentImageContext() as UIImage
      UIGraphicsEndImageContext()
      
      return newImage
  }
}

how could I set color for a specific item?

@chienpm304,
hi
Are you able to find a solution for setting colours for a specific item and other sets of different colours?
