I found an answer to this at Silent Mac Design.
I implemented this way:
First make a subclass of UITabBarContoller
// CustomUITabBarController.h
#import <UIKit/UIKit.h>
@interface CustomUITabBarController: UITabBarController {
IBOutlet UITabBar *tabBar1;
}
@property(nonatomic, retain) UITabBar *tabBar1;
@end
?
// CustomUITabBarController.m
#import "CustomUITabBarController.h"
@implementation CustomUITabBarController
@synthesize tabBar1;
- (void)viewDidLoad {
[super viewDidLoad];
CGRect frame = CGRectMake(0.0, 0, self.view.bounds.size.width, 48);
UIView *v = [[UIView alloc] initWithFrame:frame];
[v setBackgroundColor:[[UIColor alloc] initWithRed:1.0
green:0.0
blue:0.0
alpha:0.1]];
[tabBar1 insertSubview:v atIndex:0];
[v release];
}
@end
And in your Nib file replace the class of your TabBar Controller with CustomUITabBarController.
