title: Possible to create UITabBarController w/ Custom Images, Pressed/NotPressed?
body: <p>I want to add a little flair to my application and while I have been somewhat successful, I haven't figured out a way to truly do what I want to do. I would try to subclass UITabViewController, but I don't think I would even know where to start or if that is the right approach. </p>
  
  <p>Basically, what I want to do is have custom images for each tab bar button. I have both pressed and non-pressed images. Instead of using the highlight that is generated over the current icon, I want the pressed image to be shown. What I've been able to do is create a Category of the UITabBar with a custom drawRect method that basically draws all of my custom tab bar icons. I then initialize the same amount of UITabBarItems w/out specifying an image or title of any kind which I then add to the array of items. This lets me have my icons and then just overlays the highlight on them. </p>
  
  <p>This is ok I guess, but I would really like to have the pressed button look. </p>
  
  <p>Here is the code I use for drawing the tab bar:</p>
  
  <pre><code>@implementation UITabBar (CustomImage)
  
  
  -(void)drawRect:(CGRect)rect
  {
      UIImage *image = [UIImage imageNamed:@"TabBar.png"];
      [image drawInRect:CGRectMake(0,0,320,50)];
  }
  
  @end
  </code></pre>
  
  <p>And then I initialize the tab bar items like this:</p>
  
  <pre><code>UITabBarItem *homeTabBarItem = [[UITabBarItem alloc] init];
  </code></pre>
  
  <p>If anyone knows how I would do this, that would be greatly appreciated. Please keep in mind that I'm still relatively new to Objective-C, so I'm somewhat confused as to how I would correctly subclass anything at this point. </p>
  
  <p>The functionality I'm looking for would be similar to what RougeSheep was able to accomplish with Postage: <a href="http://postage.roguesheep.com/" rel="nofollow noreferrer">http://postage.roguesheep.com/</a> They did an awesome job, and this is kind of what I'd like to emulate. </p>
