纯代码给tabBar设置UIViewController

NSString *news = @"新闻";

NewsViewController *newsVC = [[NewsViewController alloc] init];

newsVC.title = news;

UINavigationController *newNC = [[UINavigationController alloc] initWithRootViewController:newsVC];

newNC.tabBarItem = [[UITabBarItem alloc] initWithTitle:news image:[UIImage imageNamed:@"tabbar_icon_news_normal"] selectedImage:[UIImage imageNamed:@"tabbar_icon_news_highlight"]];

NSString *reading = @"阅读";

ReadViewController *readingTVC = [[ReadViewController alloc]init];

readingTVC.title = reading;

UINavigationController *readingNC = [[UINavigationController alloc] initWithRootViewController:readingTVC];

readingNC.tabBarItem = [[UITabBarItem alloc] initWithTitle:reading image:[UIImage imageNamed:@"tabbar_icon_reader_normal"] selectedImage:[UIImage imageNamed:@"tabbar_icon_reader_highlight"]];

NSString *video = @"视听";

ViewController *videoTVC = [[ViewController alloc]init];

// videoTVC.title = video;

UINavigationController *videoNC = [[UINavigationController alloc] initWithRootViewController:videoTVC];

videoNC.tabBarItem = [[UITabBarItem alloc] initWithTitle:video image:[UIImage imageNamed:@"tabbar_icon_media_normal"] selectedImage:[UIImage imageNamed:@"tabbar_icon_media_highlight"]];

NSString *mine = @"我们";

MineTableViewController *mineTVC = [[MineTableViewController alloc] initWithStyle:UITableViewStyleGrouped];

mineTVC.title = mine;

UINavigationController *mineNC = [[UINavigationController alloc] initWithRootViewController:mineTVC];

mineNC.tabBarItem = [[UITabBarItem alloc] initWithTitle:mine image:[UIImage imageNamed:@"tabbar_icon_me_normal"] selectedImage:[UIImage imageNamed:@"tabbar_icon_me_highlight"]];

self.viewControllers = @[newNC, readingNC, videoNC, mineNC];
