使用splitViewControllers發送的數據更改uilabel文本

Question

我正在學習tabbar內的splitViewController。我有5個選項卡，其中第五個是splitViewController。我能夠展示它。我的MasterView確實將數據發送到DetailsView。但是的DetailView標籤不顯示它

AppDelegate.m

- (void)showMainMenu:(NSNotification *)notification { 

UserListViewController *userlist = [[UserListViewController alloc] init]; //MASTER VIEW 

UINavigationController *userListNavController = [[UINavigationController alloc] initWithRootViewController:userlist]; 

UserDetailsViewController *userDetails = [[UserDetailsViewController alloc] init]; //DETAIL VIEW 

UINavigationController *userDetailsNavController = [[UINavigationController alloc] initWithRootViewController:userDetails]; 

UISplitViewController *splitViewContr = [[UISplitViewController alloc] init]; 
splitViewContr.viewControllers = [NSArray arrayWithObjects:userListNavController,userDetailsNavController, nil]; 
splitViewContr.tabBarItem.image=kImage; 
splitViewContr.title=@"Update User"; 

NSMutableArray *viewControllerArray = [[NSMutableArray alloc] init]; 
[viewControllerArray addObject:tab1]; 
[viewControllerArray addObject:tab2]; 
[viewControllerArray addObject:tab3]; 
[viewControllerArray addObject:tab4]; 
[viewControllerArray addObject:splitViewContr]; 

self._tabBarController.viewControllers=viewControllerArray; 
[viewControllerArray release]; 

[self._tabBarController dismissModalViewControllerAnimated:NO]; 
} 

UserListViewController.m

我有一個的tableView。我只是顯示didSelectRowAtIndexPath方法：

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
NSUInteger item = [indexPath row]; 
NSNumber *detailItem = [NSNumber numberWithInteger:item]; 
userDetails = [[UserDetailsViewController alloc] init]; 
[self.userDetails setDetailItem:detailItem]; 
//self.userDetails.detailItem=detailItem; 
} 

UserDetailsViewController.m

- (void)setDetailItem:(NSNumber *)newDetailItem 
{ 
if (detailItem != newDetailItem) { 
    [detailItem release]; 
    detailItem= [newDetailItem retain]; 
    NSLog(@"DETAILS%@",detailItem); 
    [self configureView]; 
} 
} 
- (void)configureView 
{ 
if (self.detailItem) { 
    [self viewDidLoad]; 
    //incomLabel.text=[NSString stringWithFormat:@"I got Demo %d",[detailItem integerValue]]; 
} 
} 
- (void)viewDidLoad 
{ 
[super viewDidLoad]; 
// Do any additional setup after loading the view. 
self.view.backgroundColor=[UIColor whiteColor]; 
self.title=@"Update User Details"; 

incomLabel = [[UILabel alloc] initWithFrame:CGRectMake(40, 100, 250, 20)]; 

incomLabel.text=[NSString stringWithFormat:@"I got Demo %d",[detailItem integerValue]]; 
[self.view addSubview:incomLabel]; 
[incomLabel release]; 

} 

如何從大師班傳來的數據更改詳細類標籤文本。謝謝

好吧，我找到了答案。 我在AppDelegate.m內丟失了這個東西userlist.userDetails=userDetails;其中userDetails是UserListViewController中的UserDetailsViewController對象。
