Custom UITabBar icons iOS

I am developing a tabbed application and i want to integrate custom UITabbar background and icons. I already inserted a custom background but i have a problem with the icons.

This is how the icons are supposed to look:

enter image description here

But after adding the icons for each view in the storyboard i get grey icons like this:

enter image description here

Does anyone have an idea why the icons are displayed this way?

Thank you very much!

An updated Version to Julien's answer about IBInspectable is below

import UIKit

@IBDesignable
class CustomTabBarItem: UITabBarItem {
    @IBInspectable var finalImage: UIImage = UIImage() {
        didSet {
            self.image = finalImage.withRenderingMode(.alwaysOriginal)
            }
        }
    @IBInspectable var finalSelectedImage: UIImage = UIImage() {
       didSet {
            self.selectedImage = finalSelectedImage.withRenderingMode(.alwaysOriginal)
            }
        }
}

Using Xcode 6, in order to be able to change images directly from Storyboard, you can do this:

@IBDesignable class CustomizedTabBarItem: UITabBarItem {
    @IBInspectable var finalImage:UIImage = UIImage() {
        didSet {
            self.image = finalImage.imageWithRenderingMode(.AlwaysOriginal)
        }
    }
    @IBInspectable var finalSelectedImage:UIImage = UIImage() {
        didSet {
            self.selectedImage = finalSelectedImage.imageWithRenderingMode(.AlwaysOriginal)
        }
    }
}

After, you just have to set the images in your storyboard enter image description here

I can´t comment yet, so I´ll add as answer.

Since iOS 7 setFinishedSelectedImage:withFinishedUnselectedImage: is deprecated.

To solve this you can do it this way:

UIImage *selectedImage = [UIImage imageNamed:@"tabbar-highlight"];
selectedImage = [selectedImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
UIImage *unselectedImage = [UIImage imageNamed:@"tabbar"];
unselectedImage = [unselectedImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
tabBarItem = [[UITabBarItem alloc] initWithTitle:@"TabBarItem1" image:unselectedImage selectedImage:selectedImage];
//
//OR
//
UIImage *selectedImage = [UIImage imageNamed:@"tabbar-highlight"];
selectedImage = [selectedImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
UIImage *unselectedImage = [UIImage imageNamed:@"tabbar"];
unselectedImage = [unselectedImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
[yourTabBarItem setImage:unselectedImage];
[yourTabBarItem setSelectedImage:selectedImage];

Hope this help to clarify for iOS7+.

You can also keep it simple ;)

    [tabBarItemName setSelectedImage:[UIImage imageNamed:@"image name"]];

You'll have to declare the tabBarItemName in your ViewController.h

This is how I do it in one of my apps. In your AppDelegates didFinishLaunchingWithOptions: method, add this and fill in your image names:

    UITabBarController *tabController = (UITabBarController *)self.window.rootViewController;

    //tab1
    UIImage *selectedImage = [UIImage imageNamed:@"home-tab-selected"];
    UIImage *unselectedImage = [UIImage imageNamed:@"home2-tab"];
    MyTabBar *tabBar = (MyTabBar *)tabController.tabBar;
    UITabBarItem *item1 = [tabBar.items objectAtIndex:0];
    [item1 setFinishedSelectedImage:selectedImage withFinishedUnselectedImage:unselectedImage];

    //tab2
    selectedImage = [UIImage imageNamed:@"customers-tab-selected"];
    unselectedImage = [UIImage imageNamed:@"customers-tab"];
    UITabBarItem *item2 = [tabBar.items objectAtIndex:1];
    [item2 setFinishedSelectedImage:selectedImage withFinishedUnselectedImage:unselectedImage];

    //tab3
    selectedImage = [UIImage imageNamed:@"maps-tab-selected"];
    unselectedImage = [UIImage imageNamed:@"maps-tab"];
    UITabBarItem *item3 = [tabBar.items objectAtIndex:2];
    [item3 setFinishedSelectedImage:selectedImage withFinishedUnselectedImage:unselectedImage];

    //tab4
    selectedImage = [UIImage imageNamed:@"reports-tab-selected"];
    unselectedImage = [UIImage imageNamed:@"reports-tab"];
    UITabBarItem *item4 = [tabBar.items objectAtIndex:3];
    [item4 setFinishedSelectedImage:selectedImage withFinishedUnselectedImage:unselectedImage];

    //tab5
    selectedImage = [UIImage imageNamed:@"orders-tab-selected"];
    unselectedImage = [UIImage imageNamed:@"orders-tab"];
    UITabBarItem *item5 = [tabBar.items objectAtIndex:4];
    [item5 setFinishedSelectedImage:selectedImage withFinishedUnselectedImage:unselectedImage];


    if ([tabBar respondsToSelector:@selector(setBackgroundImage:)])
    {
        // ios 5 code here
        [tabBar setBackgroundImage:[UIImage imageNamed:@"tab-bg"]];

    }

Works perfect for me.

You can set the finished image of the tab bar icons with setFinishedSelectedImage:withFinishedUnselectedImage: on UITabBarItem

Check the docs here (look under Appearance)

The default behavior of the UITabBarItem is to create a mask based on your icon then it applies that special blue treatment as your seeing.
