Places On Map using Json
1) First of all Set Storyboard Like This :
- In First View Only Navigation Controller is here.
- In Second View There are it is simple use For Splash Screen .
Here in secon View Controller Only Image is set.
- In Third View Controller There are One text Field and Button is Here.
- In 4th View Controoler Table View and Map View is Taken.
2) Add Two Framework For Use of MapView :
- CoreLocation.Framework
- MapKit.Framework
3) write This Coding in Different View Controller
Which is Given Below :
* First View Controller (For Splash Screen) :
Splash Screen.h :
#import <UIKit/UIKit.h>
#import "ViewController.h"
@interface SplashScreen : UIViewController
@property(strong,nonatomic)ViewController *viewobj;
@end
Splash Screen.m :
#import "SplashScreen.h"
@interface SplashScreen ()
@end
@implementation SplashScreen
@synthesize viewobj;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
[NSTimer scheduledTimerWithTimeInterval:2.0 target:self selector:@selector(aftercomplate) userInfo:nil repeats:NO];
}
-(void)aftercomplate
{
UIStoryboard *story = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
viewobj = [story instantiateViewControllerWithIdentifier:@"ViewController"];
[self.navigationController pushViewController:viewobj animated:YES];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
@end
* Second View Controller (For Seach) :
ViewController.h :
#import <UIKit/UIKit.h>
#import "SecViewController.h"
@interface ViewController : UIViewController
@property(strong,nonatomic)IBOutlet UITextField *txtname;
@property(strong,nonatomic)SecViewController *secobj;
-(IBAction)next:(id)sender;
@end
ViewController.m :
#import "ViewController.h"
@interface ViewController ()
@end
@implementation ViewController
@synthesize txtname,secobj;
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
-(IBAction)next:(id)sender
{
NSString *stringdata = txtname.text;
UIStoryboard *story = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
secobj = [story instantiateViewControllerWithIdentifier:@"SecViewController"];
secobj.string = stringdata;
[self.navigationController pushViewController:secobj animated:YES];
}
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
[textField resignFirstResponder];
return YES;
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
@end
* Third View Controller (For Data Show & Map) :
SecViewController.h :

@end

* NSObject Class (For Data Store) :
