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.
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.
This is ok I guess, but I would really like to have the pressed button look.
Here is the code I use for drawing the tab bar:
@implementation UITabBar (CustomImage)
-(void)drawRect:(CGRect)rect
{
UIImage *image = [UIImage imageNamed:@"TabBar.png"];
[image drawInRect:CGRectMake(0,0,320,50)];
}
@end
And then I initialize the tab bar items like this:
UITabBarItem *homeTabBarItem = [[UITabBarItem alloc] init];
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.
The functionality I'm looking for would be similar to what RougeSheep was able to accomplish with Postage: http://postage.roguesheep.com/ They did an awesome job, and this is kind of what I'd like to emulate.
