I have a list of NSMutableArrays with NSMutableDictionaries in with objectsandkeys in this. like:
[silestoneArray addObject:[[NSMutableDictionary alloc]
initWithObjectsAndKeys:#"Zen: Unsui", #"name",
#"silestone-unsui1.jpg", #"image", nil]];
I have a working search but I am now trying to segue to a detail view. I need to find a way of calling up the objects and keys from the search results so that when I segue from the search results the correct data is passed on.
My didselectrowatindexpath and prepareforsegue look like this:
- (void)tableView:(UITableView *)tableView
didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if(tableView == self.mainTableView){
[self.detailViewController setDetailItem:[[contentsList objectAtIndex:indexPath.section]
objectAtIndex: indexPath.row]];}
else
[self.detailViewController setDetailItem:[[contentsList objectAtIndex:indexPath.section]
objectAtIndex: indexPath.row]];
}
#pragma mark - Segue
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([[segue identifier] isEqualToString:#"detailview"]) {
UIViewController *detailViewController = [segue destinationViewController];
// In order to manipulate the destination view controller, another check on which table (search or normal) is displayed is needed
if(sender == self.searchDisplayController.searchResultsTableView) {
detailViewController = self.detailViewController=segue.destinationViewController;
}
else {NSLog(#"Sender: %#", [sender class]);
self.detailViewController=segue.destinationViewController;
}
}
}
and this passes to a detailview which call forth the data like so:
- (void)setDetailItem:(id)newDetailItem
{
if (_detailItem != newDetailItem) {
_detailItem = newDetailItem;
// Update the view.
[self configureView];
}
}
- (void)configureView
{
// Update the user interface for the detail item.
if (self.detailItem) {
self.navigationItem.title = [self.detailItem objectForKey:#"name"];
[self.detailImage setImage:[UIImage imageNamed:self.detailItem[#"image"]]];
}
}
The problem I have at the moment is when I segue from the results it will send the results from my original table so no matter what the cell of the results says the image and title will correspond with the order of the unfiltered results.
I know this is because I am calling on contentsList for both in didselectrow but when I try with search results it crashes.
the error report is: -[__NSCFConstantString objectForKey:]: unrecognized selector sent to instance 0x21ed8
and under exemption breakpoints it says it is being thrown at this point:
self.navigationItem.title = [self.detailItem objectForKey:#"name"];
in this section of the detail view:
- (void)configureView
{
// Update the user interface for the detail item.
if (self.detailItem) {
self.navigationItem.title = [self.detailItem objectForKey:#"name"];
[self.detailImage setImage:[UIImage imageNamed:self.detailItem[#"image"]]];
}
}
Thanks for any help.

So i am trying to make an application that displays names of people in a tableview and on tap moves to the next view controller that shows an image of the person.
However when i add the search bar on the table view; i dont seem to have it right.
What am i doing wrong here?
The code compiles and displays on the simulator but when i click on any of the buttons, it gives me the errors i hate the most (Thread 1 : signal SIGABRT)

Well, just by looking at the code what I can suggest you is, first remove that call to prepareForSegue method called in UITableView's delegate method, didSelectForRowAtIndexPath.
You are overriding prepareForSegue, so in your storyboard you should have a prototype cell from where you have to ctrl-drag to the destination controller and segue it accordingly. That's a basic concept. Still having problem? Let us see your console messages when it crashes.
I trying to pass an array through prepareWithSegue but I get null when I launch the app
this is the code :
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([segue.destinationViewController isEqual:#"table"]) {
PersonsViewController *person= [[PersonsViewController alloc]init];
[person setAnArray:anArray];
person = segue.destinationViewController;
}
}
and this is setAnArray method:
-(void)setAnArray:(NSMutableArray *)anArray
{
array = [[NSMutableArray alloc]initWithArray:anArray];
if (array != nil) {
NSLog(#"array is copied !!");
}
}
the data should pass from viewController(embedded with UINavigation Controller) to PersonViewController (which is tableview) and nothing shows on the table so I NSLogged the the array count and found it zero so I did some further checking with this code:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
#warning Incomplete method implementation.
// Return the number of rows in the section.
if (array == nil) {
NSLog(#"array is null");
}
else
{
NSLog(#"array count is %lu",(unsigned long)[array count]);
return [array count];
}
and I get array is null message.
please help me to fix this
Why don't you just allocate the view controller from the storyboard and pass the array in as a property of that view controller before you add it to the stack? i.e. avoid using prepareForSegue
-(void) buttonPressed:(UIButton*) sender
{
UIStoryBoard *story = [UIStoryboard storyboardWithName:#"Storyboard name"];
YourViewController *vc = [story instantiateViewControllerWithIdentifier:#"identifier"];
vc.array = <you array>
[self.navigationController pushViewController:vc animated:YES];
}
when you assign segue.destinationViewController to person your over writing the person object you previously instantiated and assigned the array to.
you probably want to do something like this
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([segue.destinationViewController isEqual:#"table"]) {
[(PersonsViewController *) segue.destinationViewController setAnArray:anArray];
}
}
I'm trying to update a UITextView's text property, after a segue, which happens after a row of a table view is tapped.
here is my code
MasterViewController.m
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
if ([[segue identifier] isEqualToString:#"4 Choices"]) {
NSLog(#"prepareForSegue is called");
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
NSManagedObject *selectedObject = [[self fetchedResultsController] objectAtIndexPath:indexPath];
NSString *questionContent = [[selectedObject valueForKey:#"questionContent"]description];
self.questionContent = questionContent;
[segue.destinationViewController setTextViewWith:self.questionContent];
}
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSLog(#"didSelectRowAtIndexPath is called");
NSManagedObject *selectedObject = [[self fetchedResultsController] objectAtIndexPath:indexPath];
NSNumber *questionID = [selectedObject valueForKey:#"qID"];
int i = [questionID intValue];
if (i == 1) {
[self performSegueWithIdentifier:#"4 Choices" sender:self];
}
else
{
[self performSegueWithIdentifier:#"5 Choices" sender:self];
}
}
DetailViewController.m
-(void)setTextViewWith:(NSString *)aText
{
self.questionText = aText;
NSLog(#"setTextViewWith is called");
}
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
[self.questionView setText:self.questionText];
NSLog(#"viewWillAppear is called");
}
EDIT 1 : change the code to set the text at 'viewWillAppear'
EDIT 2 : add 'didSelectRowAtIndexPath'
Note : the segue was pointed from MasterViewController to DetailViewController (not from the
tableViewCell)
Thanks for your help : )
The text view may not be loaded at the prepareForSegue point. I've only just started with storyboards and have found that I had to set string properties on the destination view controller instead, then update the UI components in viewDidLoad or viewWillAppear.
I have a TabBar, NavBar, SearchBar with ScopeBar on my screen. I can search data via a remote server and list the content. So I have a NSMutableArray listContent and a filteredListContent like in the example of Apple (TableSearch - http://developer.apple.com/iphone/library/samplecode/TableSearch/index.html):
Now I added in
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
these line:
testDetailViewController *testDetailViewController = [[TestDetailViewController alloc] initWithNibName:#"TestDetailView" bundle:[NSBundle mainBundle]];
testDetailViewController.title = testClass.name;
testDetailViewController.myKey = testClass.keyId;
[[self navigationController] pushViewController:testDetailViewController animated:YES];
[testDetailViewController release];
testDetailViewController = nil;
Because of the NavigationBar, there is a "back" button. If I click this button, the TableView is empty, no matches/hits.
What I have to do, so the content will still be there?
Does anyone know?
Thanks a lot in advance & Best Regards.

You generally don't have to do anything in this case, the data should remain in place. Is there something which is unloading the data? Do you have a viewWillDisappear function which is unloading your array? Are you doing some of the array setup in viewWillAppear.
Put a log statement at the start of your methods to find out when they are being called, it will give you a clearer picture of what's happening.
It is solved. It was a problem which is not obvious with the given source code.
There was an error in my logic.
I am using this example of Apple's sample code:
http://developer.apple.com/iPhone/library/samplecode/TableSearch/index.html
In this example the UITableView get a list of content at startup. Clicking in the UISearchBar and typing, the content list will be filtered, also checking on scope of the ScopeBar.
I have to rebuild this kind of "instant search" to a "normal search": At the beginning I do not have data for the TableView. The user should click on the SearchBar, type something, press the button "Search" and a search request will be send to a webserver. The webserver´s response will be put into the TableView and the user can switch the scope to filter the result set. Changing the value of the SearchBar does not filter the result list. Only pressing the "Search" initiate a search request.
I took the example code and rebuild it (source code at the bottom).
But I have two problems with it.
At the initial call of the SearchViewController (with TabBar, SearchBar, ScopeBar, TableView), everything is okay. Thereis an empty TableView. But, clicking in the SearchBar and typing ony one character, there is a message that there are "no hits". How could I avoid that? This message should only appear if an user press "Search" and there are really no matches.
My second problem: Typing "hello" and pressing "Search" the TableView does not list the results. If I click "abort" or on a different scope, the results will be listed. So there must something like a missing "reload"?!
I hope someone could help me.
Thanks a lot in adavence & Best Regards.

For your first problem you should set up a delegate for the search bar and then implement – searchBarSearchButtonClicked: and put your searching code in there. You might also have to implement others such as – searchBarTextDidEndEditing: or – searchBar:textDidChange: and make sure that they do not perform the search.
For your second question, you might want to simply reload the tableView using the delegate again from the – searchBarSearchButtonClicked: to make sure that it happens after you have already searched. You can use [tableView reloadData] to accomplish this.
Problem is solved, see in the comments.
