JSON Using Local File Implementation in Xcode

Step1: Create A Xcode project in Name of Json

Step2: JSON Files Download Link : http://www.mediafire.com/?iw9p1bap515cojn

Step3: Import the Downloaded file into your Project.

Step4: Create the json file in Name of Asan.json.

Step5: Asan.json Write a Below Coding and Save File.

{

    "Details":

    [

        {

            "Name": "Asan",

            "Native": "From TVL"

        },

        {

            "Name": "Elavarasan",

            "Native": "From Ariyalur"

        },

        {

            "Name": "Santhosh",

            "Native": "From Vellore"

        }

    ]

}

Step6: Asan.json file is implemented to project.

Step7: open .h File and import the Codings

#import <UIKit/UIKit.h>

@interface RootViewController : UITableViewController {

    NSArray *tableData;

}

@property (nonatomic, retain) NSArray *tableData;

@end

Step8: open .m File and import the Codings

#import "JSON.h"

@synthesize tableData;

- (void)viewWillAppear:(BOOL)animated

{

    [super viewWillAppear:animated];

    

    // Download JSON

    NSString *filePath = [[NSBundle mainBundle] pathForResource:@"Asan" ofType:@"json"]; 

    NSString *fileContent = [[NSString alloc] initWithContentsOfFile:filePath];

    

    // Create parser

    SBJSON *parser = [[SBJSON alloc] init];

    NSDictionary *data = (NSDictionary *) [parser objectWithString:fileContent error:nil];

[parser release], parser = nil;

    

    // Set tableData

    [self setTableData:[data objectForKey:@"Details"]];

    

}

// Customize the number of sections in the table view.

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView

{

    return 1;

}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section

{

    return [tableData count];

}

// Customize the appearance of table view cells.

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

{

    static NSString *CellIdentifier = @"Cell";

    

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    if (cell == nil) {

        // Change UITableViewCellStyle

        cell = [[[UITableViewCell alloc] 

                 initWithStyle:UITableViewCellStyleSubtitle 

                 reuseIdentifier:CellIdentifier] autorelease];

    }

    

    // Get item from tableData

    NSDictionary *item = [tableData objectAtIndex:[indexPath row]];

    // Set text on textLabel

    [[cell textLabel] setText:[item objectForKey:@"Name"]];

    // Set text on detailTextLabel

    [[cell detailTextLabel] setText:[item objectForKey:@"Native"]];

    

    return cell;

}

- (void)viewDidUnload

{

    [self setTableData:nil];

    [super viewDidUnload];

}

- (void)dealloc

{

    [tableData release];

    [super dealloc];

}

Step9: Build and Run the Xcode Application
