问题描述
UINavigationBar和UISearchBar都有一个tintColor属性,允许你改变这两个项目的色调(我知道)。我想在我的应用程序中对UITabBar做同样的事情,但现在已经找到了从默认的黑色中改变它的方法。任何想法?
The UINavigationBar and UISearchBar both have a tintColor property that allows you to change the tint color (surprising, I know) of both of those items. I want to do the same thing to the UITabBar in my application, but have found now way to change it from the default black color. Any ideas?
推荐答案
我已经能够通过继承UITabBarController并使用私有类来实现它:
I have been able to make it work by subclassing a UITabBarController and using private classes:
@interface UITabBarController (private)
- (UITabBar *)tabBar;
@end
@implementation CustomUITabBarController
- (void)viewDidLoad {
[super viewDidLoad];
CGRect frame = CGRectMake(0.0, 0.0, self.view.bounds.size.width, 48);
UIView *v = [[UIView alloc] initWithFrame:frame];
[v setBackgroundColor:kMainColor];
[v setAlpha:0.5];
[[self tabBar] addSubview:v];
[v release];
}
@end
