我想在TabBar中使用splitview。現在我在我的第一個TabBarItem中有一個SplitView。我嘗試訪問SplitViewController中的不同DetailView或右視圖時遇到問題。從SplitViewController設置數組.viewControllers
我想在SplitView中的我的根(或主)視圖控制器的didSelectRowAtIndexPath內部執行它。
下面是代碼,我嘗試從AppDelegate對象訪問我的TabBarController,並更改我的SplitView的viewControllers數組,只更改第二個視圖控制器。我總是得到這個崩潰的錯誤,他說,第二個實例發送是無法識別的:- [SecondViewController viewControllers]:無法識別的選擇發送到實例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];
}
而且我的AppDelegate代碼(即沒有問題的作品):
- (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;
}
我在做什麼錯?任何幫助或建議是受歡迎的。
感謝所有提前。
但是我的代碼有什麼問題嗎? – agapitocandemor
SecondViewController是如何定義的? – tarmes
