1.設定tabbar背景顏色

1 NSArray *controllers = [NSArray arrayWithObjects:nav_main,nav_channle,nav_me, nil];2     _tabController.viewControllers = controllers;3     _tabController.delegate = self;4     5     for (int i=0;i<self.tabController.viewControllers.count;i++) {6         UIViewController *viewController = [self.tabController.viewControllers objectAtIndex:i];7         // 設定tabbar 背景顏色8         [viewController.tabBarController.tabBar setBackgroundImage:[UIImage imageWithColor:kTabBarBackgroundColor]];9     }

2.ios7.ios6選中 未選中顏色

 [[UITabBarItem appearance]setTitleTextAttributes:@{ UITextAttributeTextColor : cMainColor }                                                forState:UIControlStateSelected];        [[UITabBarItem appearance] setTitleTextAttributes:@{ UITextAttributeTextColor : cTabUnselect }                                                 forState:UIControlStateNormal];

以下添加font屬性

[[UITabBarItem appearance] setTitleTextAttributes:@{NSFontAttributeName : [UIFont fontWithName:@"HelveticaNeue-Bold" size:10.0f],                                                    NSForegroundColorAttributeName : appTintColor                                                    } forState:UIControlStateSelected];// doing this results in an easier to read unselected state then the default iOS 7 one[[UITabBarItem appearance] setTitleTextAttributes:@{NSFontAttributeName : [UIFont fontWithName:@"HelveticaNeue-Bold" size:10.0f],                                                    NSForegroundColorAttributeName : [UIColor colorWithRed:.5 green:.5 blue:.5 alpha:1]                                                    } forState:UIControlStateNormal];
