PRESENTATION
Mine is a simple project: It consists of a NavigationController, ViewController, and a “Search Bar and Search Display Controller”
My .h
file is
#import <UIKit/UIKit.h>
@interface ViewController : UIViewController <UISearchDisplayDelegate, UITableViewDataSource, UITableViewDelegate>
@end
and my .m
file is
#import "ViewController.h"
@interface ViewController ()
@property(nonatomic,strong)NSMutableArray *data;
@end
@implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
self.searchDisplayController.displaysSearchBarInNavigationBar = YES;
self.data=[[NSMutableArray alloc]init];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#pragma mark - data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)aTableView {
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)aTableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
return [_data count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"CellIdentifier";
// Dequeue or create a cell of the appropriate type.
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] ;
cell.accessoryType = UITableViewCellAccessoryNone;
}
// Configure the cell.
cell.textLabel.text = [NSString stringWithFormat:@"Row %d", indexPath.row];
cell.textLabel.text = [NSString stringWithFormat:@"Row %d: %@", indexPath.row, [_data objectAtIndex:indexPath.row]];
return cell;
}
#pragma mark - delegate
- (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString
{
[NSTimer scheduledTimerWithTimeInterval:2 target:self selector:@selector(mockSearch:) userInfo:searchString repeats:NO];
return NO;
}
- (void)mockSearch:(NSTimer*)timer
{
[_data removeAllObjects];
int count = 1 + random() % 20;
for (int i = 0; i < count; i++) {
[_data addObject:timer.userInfo];
}
[self.searchDisplayController.searchResultsTableView reloadData];
}
@end
And that’s the entire program. What does it do? User makes a search and the data is displayed in a TableView (similar to a google search).
PROBLEM
I need to use a CustomTableViewCell for my table. And I need to build the TableViewCell from the storyboard (easy to visualize). I am stuck with the storyboard part. How do I place a TableViewCell on the storyboard without a TableView to place it in? I had an idea, I tried it, but it didn’t work. Here is what I did. I placed a “never-to-be-used” TableViewController in the storyboard whose sole purpose is to hold my CustomTableViewCell. Then in code I subclass TableViewCell and use IBOutlet to link the sub-views of the storyboard TableViewCell to my CustomTableViewCell . And then I used my cell as
CustomTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
. This didn’t work. The tableView remained blank. And my guess for the failure is thatCustomTableViewCell
does not belong to thetableView
being dequeued from.I need the UISearchBar to always stay inside the NavigationBar. But so far
self.searchDisplayController.displaysSearchBarInNavigationBar = YES;
is not doing it. When I first start the app the searchBar is inside the NavigationBar. But as soon as I click on it, it smacks itself right in the middle of my scene/screen and never leaves.I need to add a Header to my TableView. Which I thought of doing the same way as the CustomTableViewCell, but with a UIView parent class. But again, the CustomTableViewCell portion failed.
PLEA
Thank you for any help you can provide me.
UPDATE
All I am trying to do is allow my users to launch a server side search and view the results in a tableView. This is such a basic thing, I image many people here have done this a number of times. Being new to iOS, I am stuck. But at this point, I have posted my entire project (anyone can reconstruct it), and I have explained in details all the ways I tried to solve the problem. So if someone has a sample project they don’t mind sharing, it would help very much. Or if you know of a git project please put a link to it. Thanks.
