我有一个应用程序,其中要求是以标签格式布置部分。在其中一个选项卡下,将有一个表视图,其中包含一个细节视图的segue。当我在选项卡式导航之外设置此转换时,它可以正常工作。但是,当我尝试在选项卡式导航中执行此操作时,我收到运行时错误并崩溃。是否存在一个已知的问题,即尝试使用选项卡加载segue的tableview?
谢谢! VIV

以下是您如何使用UITabBarController
第一次在UIViewController
文件中创建UINavigationController
和AppDelegate.h
的所有对象,并使用以下AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window=[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds ]];
self.viewCon=[[ViewController alloc] init];
self.navCon=[[UINavigationController alloc] initWithRootViewController:self.viewCon];
self.navCon.navigationBar.tintColor=[UIColor blackColor];
self.viewCon.title=@"First View";
self.fView=[[FirstViewController alloc] init];
self.FnavCon=[[UINavigationController alloc] initWithRootViewController:self.fView];
self.FnavCon.navigationBar.tintColor=[UIColor blackColor];
self.fView.title=@"Secound View";
self.sView=[[SecoundViewController alloc] init];
self.SnavCon=[[UINavigationController alloc] initWithRootViewController:self.sView];
self.SnavCon.navigationBar.tintColor=[UIColor blackColor];
self.sView.title=@"Third View";
.
.
// create UIViewController and UINavigationController As you need
.
.
.
UIImage *img1=[UIImage imageNamed:@"Australia.gif"];
self.tbItem1=[[UITabBarItem alloc] initWithTitle:@"First Page" image:img1 tag:1];
self.viewCon.tabBarItem=self.tbItem1;
UIImage *img2=[UIImage imageNamed:@"Cameroon.gif"];
self.tbItem2=[[UITabBarItem alloc] initWithTitle:@"Secound Page" image:img2 tag:2];
self.fView.tabBarItem=self.tbItem2;
UIImage *img3=[UIImage imageNamed:@"Canada.png"];
self.tbItem3=[[UITabBarItem alloc] initWithTitle:@"Third Page" image:img3 tag:3];
self.sView.tabBarItem=self.tbItem3;
NSMutableArray *viewArr=[[NSMutableArray alloc] init];
[viewArr addObject:self.navCon];
[viewArr addObject:self.FnavCon];
[viewArr addObject:self.SnavCon];
self.tbCon=[[UITabBarController alloc] init];
self.tbCon.viewControllers=viewArr;
[self.window addSubview:tbCon.view];
[self.window makeKeyAndVisible];
return YES;
}
