I need some help on displaying data from Master view to Details view. When a cell is selected on Master view, data will display on details view. Master Details View
All other class is a xib file to be loaded on the Details view which is being outlet in the container view. The implementation is to avoid using UISplitViewController. I'm using objective-c. Please can anyone help me.
MainContainerViewController.m
+ (MainContainerViewController *)createModalContainer:(NSString*)paramStr{
MainContainerViewController *aController = [[MainContainerViewController alloc] initWithNibName:#"MainContainerViewController" bundle:nil];
aController.title = paramStr
return aController;
}
- (void)viewDidLoad {
[super viewDidLoad];
_masterViewController = [[MasterViewController alloc]init];
[_masterTableView setDataSource:_masterViewController];
[_masterTableView setDelegate:_masterViewController];
_masterViewController.view = _masterViewController.tableView;
}
MasterViewController.m
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
switch (indexPath.row) {
case 0:
DetailsProfileViewController *detailsController = [[DetailsProfileViewController alloc] init];
detailsController.title = #"Details";
MainContainerViewController *container = MainContainerViewController.sharedInstance;
[container.detailsTableView setDataSource:detailsController];
[container.detailsTableView setDelegate:detailsController];
detailsController.view = detailsController.tableView;
[container.detailsTableView reloadData];
break;
}

I am doing a small app and I am using a UISplitVIewController and I am trying to push the UITable cell text to the detail view and display it in a UITextField. I have managed to push the string nicely when i test it with a NSLog but when i apply to the UITextField it does not display not sure why here my method: (I am doing this using a storyboard)
-(void)pushModuleName:(NSString*)moduleName
{
self.Lv4ModuleTitleTextField.text = moduleName;
NSLog(#"name pushed%#",moduleName);
}
Not sure why this doesn't work.
[UPDATE]
UITableViewController.m (where the method is called)
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *selectedModule = [NSString stringWithFormat:#"%#",[_numberOfRows objectAtIndex:indexPath.row]];
Lv4GradeViewController *lv4 = [[Lv4GradeViewController alloc] initWithNibName:nil bundle:nil];
[lv4 pushModuleName:selectedModule];
}
You are creating a new instance of Lv4GradeViewController with the following code but no XIB file which will contain the text field:
Lv4GradeViewController *lv4 = [[Lv4GradeViewController alloc] initWithNibName:nil bundle:nil];
I would suggest you instantiate Lv4GradeViewController with the storyboard instantiateViewControllerWithIdentifier method:
Lv4GradeViewController *lv4 = [self.storyboard instantiateViewControllerWithIdentifier:#"IdentifierName"];
And remember to set the storyboard ID of the Lv4GradeViewController the same as IdentifierName in the storyboard.
The problem is that you're not getting a reference to the Lv4GradeViewController that you have on screen, you're creating a new one with alloc init. A split view controller, has a viewControllers array, with the controller at index 0 being the master controller, and the one at index 1 being the detail controller. So, the didSelectRowAtIndexPath method should look like this:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *selectedModule = [NSString stringWithFormat:#"%#",[_numberOfRows objectAtIndex:indexPath.row]];
Lv4GradeViewController *lv4 = self.splitViewController.viewControllers[1];
[lv4 pushModuleName:selectedModule];
}
I have a UITableView with 2 sections. In my first section, there are 5 rows. In second section there are 2 rows. When I click on an add button,this table view has to be replicated again and again. How can I do that?
-(IBAction)addDetails:(id)sender
{
NSLog(#"value of s is %d,%d",s,210+100*s);
tvc = [[UITableViewController alloc] initWithStyle:UITableViewStyleGrouped];
tvc.tableView.frame = CGRectMake(20,200+250*s,280,280);
//CGRect rect = CGRectMake(cell.bounds.origin.x+10, cell.bounds.origin.y+10,50,30);
[tvc.tableView setSectionFooterHeight:3.0];
[tvc.tableView setSectionHeaderHeight:3.0];
[tvc.tableView setShowsVerticalScrollIndicator:YES];
// [tvc.tableView setBackgroundColor:[UIColor colorWithRed:67.0/255.0 green:185.0/255.0 blue:209.0/255.0 alpha:0.5]];
[tvc.tableView setRowHeight:30];
tvc.tableView.backgroundView = nil;
tvc.tableView.backgroundColor = [UIColor clearColor];
[tvc.tableView setSeparatorStyle:UITableViewCellSelectionStyleGray];
tvc.tableView.delegate = self;
tvc.tableView.dataSource = self;
[self.view addSubview:tvc.tableView];
s++;
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 2;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if(section == DETAIL_SECTION)
return 5;
else if(section == CALENDER_SECTION){
return 2;
}
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
}
When the addDetails Function is invoked again,I want the same table structure with different data in it within the same frame.Now frame is getting repeated.
Please help me to solve this issue
When you click on the add button, create a new UITableView instance, add it to an existing view as a subview. Position and size it according to your needs. Set its delegate and datasource to be the same delegate and datasource as the original. This way, the same delegate/datasource methods will act on each of the tables using the same logic. Whenever you reload the original table, be sure to reload all 'replicated' tables.
I am trying to to complete the 'Your Second iOS App' tutorial from the apple developer program. It is a basic tableView app. My problem is that the app is building successfully and without warnings, however I cannot get the detail view to segue from the master view. I have copied and pasted both the segue identifier and the code that apple has provided. The segue is using push and I have deleted it and tried again several times. I am testing the app in the simulator.
How can I tell if a segue is working?
Every time I copy/paste my code from Xcode into the stack overflow question text area, I get warnings at the bottom saying that code must be indented by 4 spaces??? Does this mean I have to go line-by-line indenting code?? I did the control + k and pasted in the highlighted area, however I still got the warning??
When running the simulator and looking at it, I'm trying to use a disclosure indicator by clicking on it, do I have to push something special like control = click or command = click, etc. ?

It's working when it works. But without knowing more about what you are doing it's hard to give you an answer.
Highlight the code in the textbox and then click on this button.
It will indent the code correctly for you.
I can't make sense of this question.
Edited to add
(After seeing a copy of the project that the OP mailed me)
Your segue wasn't wired up properly.
The segue is supposed to go from the cell to the next view controller, because the point is to transition on a cell click. Your segue is wired up from the controller to the detail view controller. In your project - right click on your view controller and you'll see the segue is manually connected. But right clicking on the cell doesn't show a segue connection.
Delete the current segue and recreate it, this time by control-dragging from the cell to the next view controller. You can then double check the connection by right clicking on the cell and making sure that the segue is connected.
It should look like:
If the segue is supposed to transition from your table to a detail view, and if you can't get to the detail view from the table, then your segue isn't working.
You can use the code sample button at the top of the SO editor, or you can select the code in your text editor and indent it before you copy it. For example, in Xcode it's easy to select the code, hit Command-], and copy. Then just paste into the SO editor.
Please edit your question so that it makes sense. However, I think you might be asking something along the lines of how to push a view controller from your table. If you're using a segue, and if you've created the segue in your storyboard and it's connected to both the source and destination view controllers, then you can send -performSegueWithIdentifier:sender: to your table's view controller. That is, your table view controller's -tableView:didSelectRowAtIndexPath: method should call -performSegueWithIdentifier:sender: and specify the identifier for the segue leading from the table view controller to the detail view controller. It doesn't matter whether you're using the simulator or running your app on a real device.
See the other answers from Caleb and Abizem regarding 1. and 2. If I understood your question No 3 correctly, then the answer is no. You do not have to press something in particular in the simulator when you want to select a table row or the detail desclosure indicator. Just click on those items that you would tap on your device too. If it does not segue then the chances are that its not the simulator causing the problem :)
I have two UITableViewControllers. In the first UITableView, once a user selects a cell, a new UITableViewController is pushed. I have set both UITableViews to "Grouped" in IB. However, when the second UITableViewController is pushed, it appears as a "Plain" UITableView. Is there a way to fix this?
Just as a sanity check, I changed the code so that the second UITableViewController is pushed not from the first UITableViewController, and it does appear to be "Grouped". Is there a reason this is happening?
Code From UITableViewController that is pushing second UITableViewController:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
if ([cell.text isEqualToString:#"Long Term Disability"]) {
LongDisabilityTableView *ldvc = [LongDisabilityTableView alloc];
[self.navigationController pushViewController:ldvc animated:YES];
}
if ([cell.textLabel.text isEqualToString:#"Short Term Disability"]) {
ShortDisabilityTableView *sdvc = [ShortDisabilityTableView alloc];
[self.navigationController pushViewController:sdvc animated:YES];
}
}
If you are pushing to a UITableViewController, you can force the table to be grouped by doing one of the following:
Init
MyTableController *grouped = [[MyTableController alloc] initWithStyle:UITableViewStyleGrouped];
Super
This needs to be added to a UITableViewController.
- (id)initWithStyle:(UITableViewStyle)style
{
self = [super initWithStyle:UITableViewStyleGrouped]; /* This is where the magic happens */
if (self) {
self.title = #"My Grouped Table";
}
return self;
}
Double Check
Make sure that you are not placing your UITableView on a UIViewController.
Make sure that you are calling the correct controller in your code (from didSelectRowAtIndexPath:)
Update, added after code
Well there's one reason right there, you aren't using init. See my first example above.
You should also change your code to this:
/* This assumes that your Long Term Disability cell is at index 0
and that your Short Term Disability cell is at index 1.
*/
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
switch ( indexPath.row )
{
case 0: /* #"Long Term Disability" */
LongDisabilityTableView *ldvc = [[LongDisabilityTableView alloc] initWithStyle:UITableViewStyleGrouped];
[self.navigationController pushViewController:ldvc animated:YES];
break;
case 1: /* #"Short Term Disability" */
ShortDisabilityTableView *sdvc = [[ShortDisabilityTableView alloc] initWithStyle:UITableViewStyleGrouped];
[self.navigationController pushViewController:sdvc animated:YES];
break;
}
}
I'm following Apple sample code "MultipleDetailViews" but what I want to do is that:
at start, shows the RootViewController (table view) display the default detailViewController (1st detailView)
when user selected a table cell, push into the stack, display the SubCategoriesVC (table view) in the master of the splitView but don't update the detailView.
in SubCategoriesVC, selecting a table cell.. update the detailViewController (2nd detailView)
So, in RootViewController.m, I push another navigation
...
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
SubCatVC *browseSubCatView = [[SubCatVC alloc] initWithNibName:#"SubCatVC" bundle:nil];
[self.navigationController pushViewController:browseSubCatView animated:YES];
[browseSubCatView release];
}
Then, in SubCatVC.m
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
UIViewController <SubstitutableDetailViewController> *detailViewController = nil;
SecondDetailViewController *newDetailViewController = [[SecondDetailViewController alloc] initWithNibName:#"SecondDetailViewController" bundle:nil];
detailViewController = newDetailViewController;
// Update the split view controller's view controllers array.
NSArray *viewControllers = [[NSArray alloc] initWithObjects:self.navigationController, detailViewController, nil];
self.splitViewController.viewControllers = viewControllers;
[viewControllers release];
// Dismiss the popover if it's present.
if (self.popoverController != nil) {
[self.popoverController dismissPopoverAnimated:YES];
}
// Configure the new view controller's popover button (after the view has been displayed and its toolbar/navigation bar has been created).
if (self.rootPopoverButtonItem != nil) {
[detailViewController showRootPopoverButtonItem:self.rootPopoverButtonItem];
}
[detailViewController release];
[[NSNotificationCenter defaultCenter] postNotificationName:#"updateProduct" object:nil];
}
but it didn't update my detailView.. so I don't know what's wrong?

Hope someone can advise me. Thanks
I Have not looked at your source, but but a common problem with Split views are delegates.
When you Push a new rootController ont the nav stack, you need to make sure it has the pointer to the detailViewController that you want it to talk to. You can check htis my logging the delegate before you try to update it:
In your SubCatVC (or any root for that matter):
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
//do stuff, init alloc vc's....
NSLog(#"DELEGATE: %#",self.delegate);
//push/delegate etc..
}
If you find its nil, copy the original roots delegate, or when your putting your new detail in, notify/set the root you want to comunicate with it.
If you need any more detail, just ask.
