iphone - tabbar set imagetintcolor (offstate)

问题

I see that there is [tabBar setSelectedImageTintColor:[UIColor]] which is great, but how do I set the imagetintcolor for the offstate? I can't seem to find a [tabBar setImageTintColor] or [tabBar setUnSelectedImageTintColor].

回答1:

Take a look at the "Managing the Finished and Selected Image" task's section of the docs of UITabBarItem.

And for a quick cut 'n paste:

NSArray *tabBarImages = [[NSArray alloc] initWithObjects:@"tab_a.png",
                         @"tab_b.png",
                         @"tab_c.png",
                         @"tab_d.png",
                         @"tab_e.png",
                         nil];


for (uint i=0;i<[_tabBarController.tabBar.items count];i++)
{
    UITabBarItem *uitbi = [_tabBarController.tabBar.items objectAtIndex:i];

    NSString *imageRef = [tabBarImages objectAtIndex:i];
    [uitbi setFinishedSelectedImage:[UIImage imageNamed:imageRef] withFinishedUnselectedImage:[UIImage imageNamed:imageRef]];

}

For changing the look and feel of the buttons to that level of detail, you are going to have to implement your own custom UITabBar. Here's a good reference:
