I used two tableviewcontrollers,i want to display country names array data in
first tableviewcontroller (recipeBookTableViewController) and other capital array data in second tableviewcontroller (RecipetableviewController),
when a first tableviewcontroller cell is clicked it should move to second tableviewcontroller with capital array data.
I have taken prepareforSegue method to shift to second tableview. but the method is never called.
how to send data to next tableview.
RecipeBookViewController(table1) Recipetableview(table2)
INDIA (cell) ------------> Delhi(cell)
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([segue.identifier isEqualToString:#"showRecipeDetail"])
{
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
RecipeDetailViewController *destViewController = segue.destinationViewController;
destViewController.second = [onew objectAtIndex:indexPath.row];
NSLog(#"%#",onew);
NSLog(#"data is %#",destViewController.second);
// destViewController.lable2 = [derivationArray objectAtIndex:indexPath.row];
// destViewController.image = [iconArray objectAtIndex:indexPath.row];
}
}
Problem is in creating segue.
Make sure you have created segue from cell of first table to second viewController.
Name the segue as showRecipeDetail.

I have an UISearchBar in on top of my TVC. If the search is active it displays another tableView on top of the normal tableView (this is normal). Now i need to get the "searchTableView" in prepareForSegue() because I need to call:
var newIndexPath = table.indexPathForSelectedRow!
and this fails if you search something.
I also can't do the decision in didSelectRowAtIndexPath() because the segue is called to fast because it is 'linked' directly to the UITableViewCell. I also tried to create the segue from the ViewController but this also fails because the segue needs to end on the same ViewController again.
So basically I want to ask if anyone knows how to solve the error in the Code line above will doing a search.
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
NSIndexPath *indexPath;
if (self.searchDisplayController.active)
{
indexPath = [self.searchDisplayController.searchResultsTableView indexPathForSelectedRow];
}
else
{
indexPath = [self.tableView indexPathForSelectedRow];
}
// Use the indexPath...
}
I am trying to send an NSMutableArray of the chosen cell to another view when a cell is clicked. I have the array of the chosen cell, but I can't get it to pass over.
"SearchResultsModalTableViewController.m"
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSMutableArray *aVenue = [self.venues objectAtIndex:indexPath.row];
DetailSearchResultViewController *detailVC =[[DetailSearchResultViewController alloc]init];
detailVC.venueInfo = aVenue;
NSLog(#"%#",aVenue);
}
When you use storyboards, you usually add segues from table cells to a destination storyboard. If that is what you are doing, then the way to deal with the selection is in the prepareForSegue: method of your view controller.
Here is an example. I am assuming that DetailSearchResultViewController in your code is a UINavigationController:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
DetailSearchResultViewController* destinationViewController = (DetailSearchResultViewController*)segue.destinationViewController;
NSIndexPath *p = self.tableView.indexPathForSelectedRow;
NSUInteger idx = p.row;
NSMutableArray *aVenue = [self.venues objectAtIndex:indexPath.row];DetailSearchResultViewController *detailVC =[[DetailSearchResultViewController alloc]init];
destinationViewController.venueInfo = aVenue;
[super prepareForSegue:segue sender:sender];
}
This will probably take two seconds to answer, but my search skills have not gotten me very far on this issue. I am performing a segue but I'm not sure how to grab the id on the destination. Here is my code on the tableview controller.
- (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath: NSIndexPath *)indexPath{
NSLog(#"reaching accessoryButtonTappedForRowWithIndexPath:");
[self performSegueWithIdentifier:#"leads_calls_to_detail" sender:[[self.leads_calls objectAtIndex:indexPath.row] objectForKey:#"ID"]];
}
What do I have to create on my destination view controller to be able to grab the id that I'm attempting to pass, or is the way I'm performing my segue incompatible with what I am attempting?
You should just pass values to the destinationViewController inside prepareForSegue: and pass self as the sender.. try using something like:
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if([[segue identifier] isEqualToString:#"leads_calls_to_detail"])
{
YourViewController *controller=(YourViewController *)segue.destinationViewController;
NSIndexPath *path = [self.tableView indexPathForSelectedRow];
//Or rather just save the indexPath in a property in your currentViewController when you get the accessoryButtonTappedForRowAtIndexPath callback, and use it here
controller.yourPropertyToSet = [self.leads_calls objectAtIndex:path.row];
}
}
And also according to Rob Mayoff, you can grab the index path for the row that the accessory was tapped at by using something like this:
NSIndexPath *indexPath = [self.tableView indexPathForCell:sender];//where sender is the sender passed in from prepareForSegue:
How to find indexPath for tapped accessory button in tableView
Hey there I have been working on a transit app for some time and have been stuck with this issue for a while now.
I am using iOS 5 and a storyboard. Basically I have a UITableView that displays favorite bus stop locations, when a user selects a row I use:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
Favorite *favorite = [self.favoriteItems objectAtIndex:indexPath.row];
stopString = favorite.title;
routeString = favorite.subtitle;
}
With the stop and route information of the cell the user chose I then prepare for a segue that corresponds to a segue on my storyboard, pushing a detail view controller that uses the stop name and route name to display times from a plist.
I am fairly new to Objective C and iOS so I am using a segue that my friend told me would work, however, it might be the problem. The segue looks like this:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
UIViewController *destination = segue.destinationViewController;
if ([destination respondsToSelector:#selector(setDelegate:)])
{
[destination setValue:self forKey:#"delegate"];
}
if ([destination respondsToSelector:#selector(setSelection:)])
{
NSString *route = routeString;
NSDictionary *selection1 = [NSDictionary dictionaryWithObjectsAndKeys:route, #"route", stopString, #"stop", nil];
[destination setValue:selection1 forKey:#"selection"];
}
}
After the segue in my DetailViewController I grab the stop and route information in the view DidLoad:
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
route = [selection objectForKey:#"route"];
stopName = [selection objectForKey:#"stop"];
NSLog(#"stopName: %#", stopName);
NSLog(#"routeName: %#", route);
}
Here is where my problems arise. When I run the simulator and click on an a cell in my table view, I am pushed to the DVC, however, the stopName and routeName are both null, so no information was sent or received. BUT, if I go back to the table and click another cell, the routeName and stopName are filled with the information that should have sent the first time I clicked a cell. If I continue this process it continues to send the information for the cell tapped previously, not currently.
So basically information is sending but only after I go through the segue twice. Obviously I want it to send the information and receive it the first time, but it is delayed and driving me nuts. I appreciate any help someone can give me as I have been searching the internet for days now trying to fix this issue, thank you so much in advance for any assistance!
prepareForSegue: is being called before didSelectRowAtIndexPath:. This is why the values you see always are lagging behind.
The better solution is to get the stopString and routeString values in your prepareForSegue: method (and not use didSelectRowForIndexPath: at all). The key to doing this is to realize that the sender parameter value being passed to prepareForSegue: is the UITableViewCell that was tapped. You can use the UITableView method indexPathForCell to get the cell's indexPath in your table, and then use that to look up the data in your favoriteItems array.
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
UITableViewCell *cell = (UITableViewCell*)sender;
NSIndexPath *indexPath = [self.tableView indexPathForCell:cell];
Favorite *favorite = [self.favoriteItems objectAtIndex:indexPath.row];
stopString = favorite.title;
routeString = favorite.subtitle;
UIViewController *destination = segue.destinationViewController;
if ([destination respondsToSelector:#selector(setDelegate:)])
{
[destination setValue:self forKey:#"delegate"];
}
if ([destination respondsToSelector:#selector(setSelection:)])
{
NSString *route = routeString;
NSDictionary *selection1 = [NSDictionary dictionaryWithObjectsAndKeys:route, #"route", stopString, #"stop", nil];
[destination setValue:selection1 forKey:#"selection"];
}
}
Make sure that you are NOT connecting the segue to the next view controller to the tableView CELL directly. Connect to the whole UITableViewController / UIViewController (whichever you are using) and give a name, say "segueNameInStoryboard".
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
Favorite *favorite = [self.favoriteItems objectAtIndex:indexPath.row];
stopString = favorite.title;
routeString = favorite.subtitle;
/* add this line */
[self performSegueWithIdentifier:#"segueNameInStoryboard" sender:self];
}
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if([segue.identifier isEqualToString:#"segueNameInStoryboard"])
{
UIViewController *nextViewController = segue.destinationViewController;
nextViewController.delegate = self;
NSDictionary *selection1 = [NSDictionary dictionaryWithObjectsAndKeys:routeString, #"route", stopString, #"stop", nil];
nextViewController.selection = selection1;
}
}
So, using storyboard you can create a segue from the UITableViewCell from the first tableViewController to a detailViewController.
Not too complicated, however, when a UISearchBarDisplayController is introduced into the storyboard mix, how can you segue the results cell to the detailViewController?
I am able to search without a problem, I followed this tutorial: http://clingingtoideas.blogspot.com/2010/02/uitableview-how-to-part-2-search.html
All I can do is select a row from the search, it turns blue and doesn't go to the detailViewController.
I have implemented the method prepareForSegue, which works for the non searched cells, but can't figure out this one.
Here's the solution that's based on the comment by #James Chen. Also using a different IndexPath depending on which state the table is in.
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([[segue identifier] isEqualToString:#"toDetail"]) {
Person *person = nil;
if (self.searchDisplayController.active == YES) {
NSIndexPath *indexPath = indexPath = [self.searchDisplayController.searchResultsTableView indexPathForSelectedRow];
NSLog(#"segue - section: %d, row: %d", indexPath.section, indexPath.row);
person = [self.filteredPersonArray objectAtIndex:indexPath.row];
}
else {
NSIndexPath *indexPath = indexPath = [self.tableView indexPathForSelectedRow];
NSLog(#"segue - section: %d, row: %d", indexPath.section, indexPath.row);
person = [self.personArray objectAtIndex:indexPath.row];
}
[[segue destinationViewController] setPerson:person];
}
}
I tried your solution and found that prepareForSegue is called twice
due to the life cycle and didSelect... -> performSegueWithIdentifier.
self:prepareForSegue: object on destination controller is set
(with wrong index) because
dest:viewDidLoad: the destination controller view is loaded after which
self:didSelectRow...: the index is known and properly set.
self:prepareForSegue: object is now correct but has no side effect.
I then focused on didSelect... and came up with this solution where I deleted the segue and pushed the view programmatically:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
DestTableViewController *controller = [self.storyboard instantiateViewControllerWithIdentifier:#"DestViewController"];
CustomObj *custObj = nil;
if (tableView == self.searchDisplayController.searchResultsTableView) {
custObj = [filteredListContent objectAtIndex:indexPath.row];
} else {
storeToDetail = [self.fetchedResultsController objectAtIndexPath:indexPath];
}
controller.custObj = custObj;
[self.navigationController setNavigationBarHidden:NO];
[self.navigationController pushViewController:controller animated:YES];
// presentViewController::animated:completion is always full screen (see problem below)
}
I then experienced some problems going back because I follow a segue
from a mapView, which lead to:
//DestinationViewController
- (IBAction)back:(id)sender
{
[self.navigationController popToRootViewControllerAnimated:YES]; // list
[self.presentingViewController dismissViewControllerAnimated:YES completion:nil]; // map
}
which is not the way to do it but for now it works.
However, the first part is easy and clean, and maybe it works for you too?!
Ok I think I got it, it seems like a bit of a hack but it works for my purposes:
I am using storyboard:
I have a UITableview controller with UISearchBarDisplayController directly on top of it. No code just drag and drop.
From there, I followed this tutorial to get the search bar to search correctly http://clingingtoideas.blogspot.com/2010/02/uitableview-how-to-part-2-search.html
However prepareForSegue: would only let me display a cell from the original array, not with the search array.
So I used didSelectRowAtIndexPath:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if (savedSearchTerm) {
searchRowSelected = indexPath.row; //<-- the trick that worked
[self performSegueWithIdentifier:#"ShowDetail" sender:self];
}
}
searchRowSelected is an int variable that I declared at the top of the class.
didSelectRowAtIndexPath: knew which row I was selecting, but prepareForSegue didn't. Thats why I needed that variable.
This is how I used it in prepareForSegue:
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
if ([segue.identifier isEqualToString:#"ShowDetail"]) {
dvc = [segue destinationViewController];
NSIndexPath* path = [self.tableView indexPathForSelectedRow];
int row = [path row];
if (savedSearchTerm){ //set the detailViewController with the searched data cell
myDataClass* c = [searchResults objectAtIndex:searchRowSelected];
dvc.myDataClass = c;
}else{ //set the detailViewController with the original data cell
myDataClass* c = [array objectAtIndex:row];
dvc.myDataClass = c;
}
}
}
Also use this code to clean up savedSearchTerm
-(void) searchDisplayControllerWillEndSearch:(UISearchDisplayController *)controller{
[self setSavedSearchTerm:nil];
}
If anyone has a better solution I'm all ears :)
