我正在尝试在 TabBar 中使用 splitview。到目前为止，我的第一个 TabBarItem 中有一个 SplitView。当我尝试在我拥有的 SplitViewController 中访问不同的 DetailView 或右视图时，我的问题就出现了。
我正在尝试在 SplitView 的根（或主）视图控制器的 didSelectRowAtIndexPath: 中执行此操作。
这是代码，我尝试从 AppDelegate 对象访问我的 TabBarController，并更改我的 SplitView 的 viewControllers 数组，只更改第二个视图控制器。我总是收到这个崩溃错误，说第二个实例发送无法识别：-[SecondViewController viewControllers]: unrecognized selector sent to instance 0x6852460
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
//object AppDelegate
AppDelegate *myDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
//Objecte in Index 0 is my SplitVC
NSArray *barControllers = myDelegate.tabBarController.viewControllers;
if (indexPath.row == 0)
{
SplitVC *temporalSplit = [barControllers objectAtIndex:indexPath.row];
NSArray *mArray = temporalSplit.viewControllers;
FirstViewController *detail = [[FirstViewController alloc]initWithNibName:@"FirstViewController" bundle:nil];
UINavigationController *navigationDetail = [[UINavigationController alloc]initWithRootViewController:detail];
temporalSplit.delegate = detail;
temporalSplit.viewControllers = [[NSArray alloc] initWithObjects:[mArray objectAtIndex:0], navigationDetail, nil];
myDelegate.tabBarController.viewControllers = [NSArray arrayWithObjects:temporalSplit.viewControllers, [barControllers objectAtIndex:1], nil];
}
else if (indexPath.row == 1)
{
SplitVC *temporalSplit = [barControllers objectAtIndex:indexPath.row];
NSArray *mArray = temporalSplit.viewControllers;
Detail2VC *detail = [[Detail2VC alloc]initWithNibName:@"Detail2VC" bundle:nil];
UINavigationController *navigationDetail = [[UINavigationController alloc]initWithRootViewController:detail];
temporalSplit.delegate = detail;
temporalSplit.viewControllers = [[NSArray alloc] initWithObjects:[mArray objectAtIndex:0], navigationDetail, nil];
myDelegate.tabBarController.viewControllers = [NSArray arrayWithObjects:[barControllers objectAtIndex:0], temporalSplit, nil];
}
[myDelegate release];
}
还有我的 AppDelegate 代码（可以正常工作）：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
self.tabBarController = [[[UITabBarController alloc] init] autorelease];
// Override point for customization after application launch.
NSMutableArray *controllersBar = [[NSMutableArray alloc]init];
UIViewController *viewController2 = [[[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil] autorelease];
for (int i = 0; i<2; i++)
{
if(i == 0)
{
_firstViewController = [[[FirstViewController alloc] initWithNibName:@"FirstViewController" bundle:nil] autorelease];
_masterApp = [[MasterVC alloc]initWithNibName:@"MasterVC" bundle:nil];
_masterApp.firstViewController = _firstViewController;
_firstViewController.mastervc = _masterApp;
UINavigationController *navigationMaster = [[UINavigationController alloc]initWithRootViewController:_masterApp];
UINavigationController *navigationDetail = [[UINavigationController alloc]initWithRootViewController:_firstViewController];
_splitVC = [[SplitVC alloc] initWithNibName:nil bundle:nil];
//_splitVC.tabBarItem = controller.tabBarItem;
_splitVC.viewControllers = [NSArray arrayWithObjects:navigationMaster, navigationDetail, nil];
_splitVC.delegate = _firstViewController;
[controllersBar addObject:_splitVC];
}
else if (i == 1)
{
[controllersBar addObject:viewController2];
}
}
//self.tabBarController.viewControllers = [NSArray arrayWithObjects:viewController1, viewController2, nil];
_tabBarController.viewControllers = controllersBar;
_tabBarController.selectedIndex = 0;
_tabBarController.delegate = self;
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
return YES;
}
我究竟做错了什么？欢迎任何帮助或建议。
提前感谢大家。
