Heres a few photos to get started:
This is what I CURRENTLY have for the main view:
Then when the user selects the UISearchBar, this is what happens:
Instead of the second photo, I would like the view to change to this:
Here is the code so far:

{

self.searchView.searchResults.delegate = self;

*/

[self.mainTableView setDelegate:self];
[self.mainTableView setDataSource:self];
[self.mainTableView setShowsHorizontalScrollIndicator:NO];

[self.searchCon setSearchResultsDataSource:self];
[self.searchCon setSearchResultsDelegate:self];
self.navigationItem.titleView = self.searchCon.searchBar;
/* This generates the result I want but I do not want the search
* bar in the tableviews header, but rather in the uinavigationcontroller's
* uinavigationbar.
*/
//self.mainTableView.tableHeaderView = self.searchBar;
[self.view setBackgroundColor:[UIColor whiteColor]];

I am kinda lost on how to make the destination view work. Viewing the Facebook application is something I would like to reproduce, the way their search bars are implemented.
In addition, I'm using the PARSE framework. So a lot of the data being populated into the tableview is abstracted from the code.
Try this...
In your .h file
#interface YourtViewController : UIViewController <UITableViewDataSource,UITableViewDelegate,UISearchBarDelegate,UISearchDisplayDelegate>
#property (nonatomic,strong) UISearchDisplayController* searchDisplayController;
#property (weak, nonatomic) IBOutlet UISearchBar *mySearchBar; //connect this IBOutlet to your serach bar in your storyboard or xib.
In your viewDidLoad
- (void)viewDidLoad
{
[super viewDidLoad];
self.mySearchBar.delegate=self;
self.searchDisplayController = [[UISearchDisplayController alloc] initWithSearchBar:self.mySearchBar contentsController:self];
self.searchDisplayController.delegate = self;
self.searchDisplayController.searchResultsDataSource = self;
self.searchDisplayController.searchResultsDelegate = self;
// do your additional code here
//
}
Now implement delegate methods of searchDisplayController.

Ok got your point. I think you want to pass data of selected cell to
next UIViewController. Assume, you want to pass cell title label and
you have an array of objects. In yoursmsDisplayViewController.h
#import <UIKit/UIKit.h>
#interface smsDisplayViewController : UIViewController
#property (strong, nonatomic) NSString *cellName;
Now in your SmsCategoryTitleTableViewController.m you have
NSMutableArray *nameList;
Then in your table view delegate method
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:YES];
smsDisplayViewController *viewController1 = [self.storyboard instantiateViewControllerWithIdentifier:#"LoginIdentifier"];
viewController1.cellName=[nameList objectAtIndex:indexPath.row];
[self.navigationController pushViewController:viewController1 animated:YES];
}
UPDATE This is the code you posted first in your question.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:YES];
smsDisplayViewController *viewController1 = [[smsDisplayViewController
alloc] initWithNibName:#"viewController1" bundle:nil];
[self.navigationController pushViewController:viewController1 animated:YES];
}
Now the wrong thing you are doing here
isinitWithNibName:#"viewController1". If you are not using any nib
file then your code should be
smsDisplayViewController *viewController1 = [[smsDisplayViewController alloc] init];
[self.navigationController pushViewController:viewController1 animated:YES];
You can use Accessory Buttons in UITableView or learn more about segues.
You have to use prepareForSegue: to pass data to another ViewController.
You can learn it from Here which teaches you how to transfer data between ViewControllers while using Segue.
I'm using a UISearchDisplayController in my app. When the user selects an item in the search results returned I deactivate the UISearchDisplayController. Deactivating the controller clears the text the user has typed. I want to keep it there. I try to assign the text back into the UISearchBar by setting it again after the controller has been deactivated. The text does appear in the search bar but this will cause the UISearchDisplayController to active again even though I have disable the delegate! This issue only happens on iOS 7. Before iOS7, the code below works charmingly.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
NSUInteger row = [indexPath row];
NSString *term = [keywordSuggestion objectAtIndex:row];
[search resignFirstResponder];
[self handleSearchForTerm:term];
}
-(void)handleSearchForTerm:(NSString *)searchTerm {
[searchDisplayController setActive:NO animated:YES]; //searchbar text will be lost
searchDisplayController.delegate = nil;
search.text = term;
searchDisplayController.delegate = self;
}
Is there are a way that I can set the text of the UISearchBar without having the UISearchDisplayController that's associated with become active?
Here is an example of some working code:

#interface RBTableViewController () <UISearchDisplayDelegate>
#end

UISearchBar *_searchBar;
UISearchDisplayController *_searchController;

I want to implement a UISearchDisplayController in a UIViewController, hence there is no UITableView implemented. I created the UISearchBar and UISearchDisplayController and implemented the corresponding delegate methods.
When I run the app and try searching, the table view that should be shown with the search results do not appear. To explain more my app UI, the UIViewController has a map and the search bar is placed in the navigation controller.
What I understood for now, it seems like I should implement a table view in order to be reused for the search results. However, there is no place/need to place a table view. What can I do to fix this? Any hints?
Here is the code how I implemented everything:
- (void)viewDidLoad{
[super viewDidLoad];
// Do any additional setup after loading the view.
_search = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, 100, 30)];
[_search setAutoresizingMask:UIViewAutoresizingFlexibleWidth];
[_search setPlaceholder:#"Search"];
self.navigationItem.titleView = _search;
_searchArray = [[NSMutableArray alloc] initWithObjects:#"Hi", nil];
_searchDisplay = [[UISearchDisplayController alloc] initWithSearchBar:_search contentsController:self];
_searchDisplay.delegate = self;
_searchDisplay.searchResultsDataSource = self;
_searchDisplay.searchResultsDelegate = self;
[_searchDisplay setActive:YES animated:YES];
filteredResults = [[NSMutableArray alloc] init];}
-(void) filterForSearchText:(NSString *) text scope:(NSString *) scope
{
[filteredResults removeAllObjects]; // clearing filter array
NSPredicate *filterPredicate = [NSPredicate predicateWithFormat:#"SELF contains[c] %#",text]; // Creating filter condition
filteredResults = [NSMutableArray arrayWithArray:[_searchArray filteredArrayUsingPredicate:filterPredicate]]; // filtering result
NSLog(#"search %#", filteredResults);
}

I'm trying to use the MWFeedParser library in my app. On my homescreen, I have a view controller named NewsViewController.
In the MWFeedParser library, the root view controller is called RootViewController. I've tried to copy all the code from the RootViewController into the NewsViewController .H + .M and in IB I've linked the tableview to "dataSource" and "delegate". But when my app starts the tableview is empty.
Here's how to code looks like:
.H:
#import <UIKit/UIKit.h>
#import "MWFeedItem.h"
#import "MWFeedParser.h"
#interface NewsViewController : UITableViewController <MWFeedParserDelegate, UITableViewDelegate, UITableViewDataSource> {
// Parsing
MWFeedParser *feedParser;
NSMutableArray *parsedItems;
// Displaying
NSArray *itemsToDisplay;
NSDateFormatter *formatter;
IBOutlet UITableView *tableView;
}
// Properties
#property (nonatomic, retain) NSArray *itemsToDisplay;
#property (nonatomic, retain) IBOutlet UITableView *tableView;
-(IBAction)goHome;
#end
.M:
#import "NSString+HTML.h"
#import "MWFeedParser.h"
#import "DetailTableViewController.h"
#implementation NewsViewController

Please help me fix this!
you can follow the following link to use MWFeedParser : https://0club1.blogspot.in/
If your Table view is empty, you could have got the following error:
NSURLSession/NSURLConnection HTTP load failed
To allow HTTP, we need to allow arbitrary loads in App Transport Security Settings. Select info.plist in your project, in Information property list add new list as App Transport Security Settings.
Within that add Allow Arbitary Loads and mark it as YES.
I have an iPhone app that I'm wanting to make a universal app and implement a split view on the iPad. I have the master view set up so that when the user selects a row, the master view goes to another table view. When a row is selected in that table view, I want the detail view to show my web view. This all works but the issue I'm having is when the web view shows on the detail view, it is just getting added to the navigation stack instead of just replacing what is currently there. This makes it so that the user has to press the back button on the detail view navigation bar in order to make another selection in the master view. If another selection is made in the master view without pressing the back button on the detail view, the app crashes.
I need to figure out how to have the web view not get added to the navigation stack of the detail view and instead replace the current detail view.
