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>


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;


@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];


- (void)didReceiveMemoryWarning
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.

#pragma Table View Methods

-(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];

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
    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;

#pragma Search Methods

- (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]

    return YES;


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 :)

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