Better way is create a subClass of <code>UITabBarController</code>

To changeBackGround Color ,

<pre><code> self.tabBar.backgroundColor = [UIColor redColor];
</code></pre>

for tintColor

<pre><code>self.tabBar.barTintColor = [UIColor greenColor];
</code></pre>

in ' init ' method itself.

For seetTitle

create an array

<pre><code>//title

titleArray = [[NSMutableArray alloc]initWithObjects:@"Title 1",@"Title 2",@"Title 3", nil];

//image array

NSArray *imageArray = @[image1,image2,image3];



for (int i = 0; i&lt; imageArray.count; i++)
 {
 UINavigationController *nav = [self.viewControllers objectAtIndex:i];
 [nav.tabBarItem setTitle:[titleArray objectAtIndex:i]];

 //You can adjust title position by adjust `titlePositionAdjustment`
 nav.tabBarItem.titlePositionAdjustment = UIOffsetMake(0, -15);

 //for add image on tabbr item for ios 7
 nav.tabBarItem.image = [[imageArray objectAtIndex:i]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

 }
</code></pre>

To add image on ios 6

<pre><code>nav.tabBarItem.image = [imageArray objectAtIndex:i];
</code></pre>

To cahnge selected image in ios 7

<pre><code>nav.tabBarItem.image = [imageArray objectAtIndex:i];
</code></pre>

for ios 6

<pre><code>nav.tabBarItem.selectedImage = [imageArraySelected objectAtIndex:i];
</code></pre>

Adjust Image EdgeInset

<pre><code>nav.tabBarItem.imageInsets = UIEdgeInsetsMake(14,0.0, -14,-2);
</code></pre>

For add title Attibutes

<pre><code>[nav.tabBarItem setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor],NSForegroundColorAttributeName,[UIFont fontWithName:@"Helvetica-Bold" size:14.0f],NSFontAttributeName, nil] forState:UIControlStateNormal];
</code></pre>

I have a simple design for each TabBar item :

<ul>
<li>a background color:

firstTab width = 1/3 of the screen(left) height = tabBarHeight
 secondTab width = 1/3 of the screen(in the middle) height = tabBarHeight
 thirdTab width = 1/3 of the screen(right) height = tabBarHeight</li>
<li>a title centered horizontal and vertical of the tabbaritem</li>
</ul>

I found different articles about how to change the entire tabbar background like this :

<pre><code>UIImage* tabBarBackground = [UIImage imageNamed:@"tabbar.png"];
[[UITabBar appearance] setBackgroundImage:tabBarBackground];
</code></pre>

And I found selected images per tabbaritem but that doesn't fill the entire tab :

<pre><code>[[tabBarController.tabBar.items objectAtIndex:0] setFinishedSelectedImage:[UIImage imageNamed:@"tabbaritem.png"] withFinishedUnselectedImage:[UIImage imageNamed:@"tabbaritem.png"]];
</code></pre>
