Json Parsing Example

Steps

first Add "ASSIHTTP" and "JSON" to your project

add all this framework to your project

in your .h file import and set delegate 

#import "HttpWrapper.h"  //import class then add delegete of this
@interface ViewController : UIViewController<HttpWrapperDelegate>
{
}@end

in your .m file call the webservice

-(void)loadWebseviceData

{

 HttpWrapper *httpWrapper=[[HttpWrapper alloc]initWithDelegate:self]; // create object of class with deleget method
    NSMutableDictionary *dicPass=[[NSMutableDictionary alloc]init]; // create a dictionary for a send parameter
    [dicPass setValue:@"Appointments" forKey:@"action"];   //pass action to webseriver
    [dicPass setValue:appDelegate.userId forKey:@"id"];   // pass parameter
    [httpWrapper requestWithMethod:@"POST" url:WEB_URL param:dicPass selSuc:@selector(fetchDataSuccessForClient:) selFail:@selector(fetchDataFail:)];   // fetch data 

}

// if fetch data sucess then call this

-(void)fetchDataSuccessForClient:(NSMutableDictionary *)response
{

 NSLog(@"%@",response);

}


// if fetch data fail then then call this
-(void)fetchDataFail:(NSError *)error
{
