我已經在我的項目中實現了this tutorial,但是segue不起作用!我已經嘗試過所有的東西,但是單擊時單元格保持突出顯示。我曾嘗試在推送中添加標識符 - 沒有區別。我的標籤欄以編程方式添加到我的appdelegate中 - 可以這樣嗎?此外tableview拒絕適合在屏幕上,它重疊狀態欄(嘗試幾乎所有的東西)。TableViewController不會延續到詳細視圖

我的appdelegate文件(標籤欄的東西)
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
//Add tab bar
UITabBarController *tbc = [[UITabBarController alloc]init];
//Specify viewcontrollers for each tab

TableViewController *evc = [[TableViewController alloc]init];
AboutViewController *avc = [[AboutViewController alloc]init];
//Label for tabs
[mvc.tabBarItem setTitle:@"Map"];
[evc.tabBarItem setTitle:@"Eat"];
[avc.tabBarItem setTitle:@"About"];
[mvc.tabBarItem setImage:[UIImage imageNamed:@"103-map.png"]];
[evc.tabBarItem setImage:[UIImage imageNamed:@"125-food.png"]];
[avc.tabBarItem setImage:[UIImage imageNamed:@"28-star.png"]];
[tbc setViewControllers:[NSArray arrayWithObjects:mvc, evc, avc, nil]];
//Add the view controller's view to the window and display.
[self.window setRootViewController:tbc]; //tab bars

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
