Searching dictionary (NSDict) and displaying results

[Shane-dev]

Can anyone help me? I have created a dictionary with the contents of a plist(data.plist) file but now I cannot figure out how to search and display the contents. I have searched online for days and cannot get a resolution.

Most tutorials show a pre-defined array being used but if I change it to my plist it crashes.

Any help would be greatly appreciated.

You need to post your code before we can help you. Just generalities like you posted are not helpful to determine the cause of your problem.

Ah, okay. Sorry I didn't know whether or not that was frowned upon.

//
//  ViewController.h
//  Search
//
//

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController <UITableViewDataSource, UITableViewDelegate, UISearchDisplayDelegate>

@end

Here is my .m file as well.

//
//  ViewController.m
//  Search
//
//

#import "ViewController.h"

@interface ViewController ()

@property (strong, nonatomic) NSArray *array;
@property (strong, nonatomic) NSArray *arrayCount;
@property (strong, nonatomic) NSArray *searchResults;
@property (strong, nonatomic) NSMutableArray *filteredTableData;

@end

@implementation ViewController

int arrayCounter = 0;
NSString *test = @"";


- (void)viewDidLoad
{
    [super viewDidLoad];

    NSDictionary *dict = [NSDictionary dictionaryWithContentsOfFile:[[NSBundle mainBundle]pathForResource:@"data" ofType:@"plist"]];

    NSMutableArray *arr = [[NSMutableArray alloc] initWithContentsOfFile:[[NSBundle mainBundle]pathForResource:@"data" ofType:@"plist"]];


    self.arrayCount = [[NSArray alloc] initWithContentsOfFile:[[NSBundle mainBundle]pathForResource:@"data" ofType:@"plist"]];
    NSLog(@"Array size: %d", [self.arrayCount count]);

    //self.array = [[NSArray alloc] initWithObjects: @"Test", @"Test 2", @"Test 3", nil];

    self.array = [[NSMutableArray alloc] initWithContentsOfFile:[[NSBundle mainBundle]pathForResource:@"data" ofType:@"plist"]];

    self.searchResults = [[NSArray alloc] init];

}

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    if (tableView == self.searchDisplayController.searchResultsTableView) {
        return [self.searchResults count];

    } else {
        return [self.array count];
    }
//    return [self.array count];
}

{
    static NSString *cellID = @"cellID";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellID];
    if (cell == nil)
    {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellID];
    }
    if (tableView == self.searchDisplayController.searchResultsTableView) {
        cell.textLabel.text = [self.searchResults objectAtIndex:indexPath.row];

    } else {
        cell.textLabel.text = [self.array objectAtIndex:indexPath.row];
    }
//    cell.textLabel.text = [self.array objectAtIndex:indexPath.row];
    return cell;
}

- (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope
{
    NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF beginswith[c] %@", searchText];
//    NSPredicate *resultPredicate = [NSPredicate predicateWithFormat:@"contains[c] %@", searchText];
    self.searchResults = [self.array filteredArrayUsingPredicate:predicate];
}

-(BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString
{
    [self filterContentForSearchText:searchString
                               scope:[[self.searchDisplayController.searchBar scopeButtonTitles]
                                      objectAtIndex:[self.searchDisplayController.searchBar
                                                     selectedScopeButtonIndex]]];

    return YES;
}

@end

Data.plist:
Root
Item 0 - Dictionary
Cell - String ( Bob )
Item 1 - Dictionary
Cell - String ( Bob 2 )
Item 2 - Dictionary
Cell - String ( Bob 3 )

And see if I populate the array with objects instead of withcontents of file it functions fine and populates the results.

Thanks for looking into this :)

Anyone have any idea on how I can get this running?

[Shane-dev]

I guess thanks anyways. I will go ahead and create a new post to donate again to see if I can gain further attention.
