1.自定义tabBarController
1.1 设置tabBarItem的相关属性
/**
设置tabBarItem的相关属性
*/
- (void)setupItemTextAttrs {
//普通状态下的文字属性
NSMutableDictionary *norAttrs = [[NSMutableDictionary alloc] init];
norAttrs[NSForegroundColorAttributeName] = [UIColor grayColor];
//选中状态下的文字属性
NSMutableDictionary *selectedAttrs = [NSMutableDictionary dictionary];
selectedAttrs[NSForegroundColorAttributeName] = [UIColor darkGrayColor];
//统一设置UITabBarItem的属性
UITabBarItem *item = [UITabBarItem appearance];
[item setTitleTextAttributes:norAttrs forState:UIControlStateNormal];
[item setTitleTextAttributes:selectedAttrs forState:UIControlStateSelected];
}
1.2 添加子控制器
/**
添加子控制器
*/
- (void)setupChildVcs {
[self setupOneChildVc:[[LXXEssenceViewController alloc] init] title:@"精华" image:@"tabBar_essence_icon" selectedImage:@"tabBar_essence_click_icon"];
[self setupOneChildVc:[[LXXNewViewController alloc] init] title:@"新帖" image:@"tabBar_new_icon" selectedImage:@"tabBar_new_click_icon"];
[self setupOneChildVc:[[LXXFriendTrendsViewController alloc] init] title:@"关注" image:@"tabBar_friendTrends_icon" selectedImage:@"tabBar_friendTrends_click_icon"];
[self setupOneChildVc:[[LXXMeViewController alloc] init] title:@"我" image:@"tabBar_me_icon" selectedImage:@"tabBar_me_click_icon"];
}
/**
设置tabBar
*/
- (void)setupOneChildVc:(UIViewController *)vc title:(NSString *)title image:(NSString *)image selectedImage:(NSString *)selectedImage
{
vc.title = title;
vc.tabBarItem.image = [UIImage imageNamed:image];
vc.tabBarItem.selectedImage = [UIImage imageNamed:selectedImage];
[self addChildViewController:vc];
}
