IOS 7 Xcode Search Bar Controller Implementation - xcode

Question

Sunny Thank you for your reply. I made the following changes and now by clicking on a tablecell or search result, I am pushed to DetailViewController but, for any cell I click on I get the same DetailView. I need the detail view to show different information depending on the cell I click on.
I added this:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if (tableView == self.searchDisplayController.searchResultsTableView) {
[self performSegueWithIdentifier: #"ShowDetails" sender: self];
}
}
New segue:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([[segue identifier] isEqualToString:#"ShowDetails"]) {
DetailViewController *detailviewcontroller = [segue destinationViewController];
NSIndexPath *myIndexPath = [self.tableView indexPathForSelectedRow];
int row = [myIndexPath row];
detailviewcontroller.DetailModal = #[_Title[row],_Attribute[row]];
}
}
update:
The reason I am having difficulty in implementing your code is because my information to be passed to the detailview is in DetailViewController.h but as an array not a string:
#property (nonatomic,strong) NSArray *Title;
#property (nonatomic,strong) NSArray *Attribute;
in the viewdidload I get these from my plist:
NSDictionary *dict = [[NSDictionary alloc] initWithContentsOfFile:path];
_Title = [dict objectForKey:#"caseName"];
_Attribute= [dict objectForKey:#"attribute"];
the table view is populated with said data with the following:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"TableViewCell";
TableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[TableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
if (tableView == self.searchDisplayController.searchResultsTableView)
{
cell.textLabel.text = [self.searchResult objectAtIndex:indexPath.row];
}
else
{
cell.TitleLabel.text = self.Title[indexPath.row];
cell.AttributeLabel.text = self.Attribute[indexPath.row];
}
return cell;
}
Then in the DetailViewController.h:
#property (strong, nonatomic) IBOutlet UILabel *TitleLabel;
#property (nonatomic,strong) IBOutlet UILabel *AttributeLabel;
#property (nonatomic,strong) NSArray *DetailModal;
DetailViewController.m:
_TitleLabel.text = _DetailModal[0];
_AttributeLabel.text = _DetailModal[1];
My segue:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([[segue identifier] isEqualToString:#"ShowDetails"]) {
DetailViewController *detailviewcontroller = [segue destinationViewController];
NSIndexPath *myIndexPath = [self.tableView indexPathForSelectedRow];
int row = [myIndexPath row];
detailviewcontroller.DetailModal = #[_Title[row],_Attribute[row]];
}
}
I thought it would help to put more of my code so you're able to get clearer picture. In my non expert opinion, I think the reason your code doesn't work for me is because my data is being stored in an array (DetailModal) and not in a string.
Thank you for taking the time to help me with this

You should implement TableView delegate;
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
if (tableView == self.searchDisplayController.searchResultsTableView) {
[self performSegueWithIdentifier:kSHOW_DETAILS sender:cell];
}
else {
[self performSegueWithIdentifier:kSHOW_DETAILS sender:cell];
}
}
Update:
You have to set the value to be displayed in the detailed view. You might declare a property in the header file for your detailView which you might set in prepareForSegue (or in the didSelectRowAtIndexPath above). For example, in DetailViewController you might do this:
#interface DetailViewController: UIViewController
#property (weak, nonatomic) NSString *myDetailValue;
#end
Then in tableView: didSelectRowAtIndexPath: above, set the correct value before you do the segue:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
if (tableView == self.searchDisplayController.searchResultsTableView) {
// TODO select value from filteredList to set the detailViewController, e.g.:
self.detailedViewController.myDetailValue = valueFromFilteredListForIndexPath;
[self performSegueWithIdentifier:kSHOW_DETAILS sender:cell];
}
else {
// TODO select value from regular list to set the detailViewController, e.g.:
self.detailedViewController.myDetailValue = valueFromRegularListForIndexPath;
[self performSegueWithIdentifier:kSHOW_DETAILS sender:cell];
}
}
Similarly, you can do it the prepare for segue:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([[segue identifier] isEqualToString:#"ShowDetails"]) {
DetailViewController *detailviewcontroller = [segue destinationViewController];
NSIndexPath *myIndexPath;
if (self.inSearch) {
myIndexPath = [self.searchDisplayController.searchResultsTableView indexPathForSelectedRow];
detailedViewController.myDetailValue = valueFromFilteredListForIndexPath;
}
else {
myIndexPath = [self.tableView indexPathForSelectedRow];
detailedViewController.myDetailValue = valueFromRegularListForIndexPath;
}
}
}
