i Can get the data from DataList1 and cannot know how to get the data from DataList2. Below is the code what i have tried. Please help to find out the solution. Thanks in Advance
- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
[jsonArray removeAllObjects];
NSString *responseString = [[NSString alloc] initWithData:self.responseData encoding:NSUTF8StringEncoding];
self.responseData = nil;
NSMutableDictionary *sdf = [(NSDictionary*)[responseString JSONValue] objectForKey:#"DataTable"];
NSMutableArray * myArray = [[NSMutableArray alloc] init];
if (([(NSString*)sdf isEqual: [NSNull null]])) {
UIAlertView *alert=[[UIAlertView alloc]initWithTitle:#"Information" message:#"Currently there are no Data" delegate:self cancelButtonTitle:#"Ok" otherButtonTitles:nil];
[alert setTag:1];
[alert show];
}else {
[myArray addObject:[sdf objectForKey:#"DataList1"]];
jsonArray=[myArray mutableCopy];
refilldict=[jsonArray objectAtIndex:0];
NSArray *keys = [refilldict allKeys];
for(int p=0 ; p<[keys count]; p++ )
{
NSString *value=[refilldict objectForKey:[keys objectAtIndex:p]];
if ([value isEqual: [NSNull null]]||[value length]==0) {
[refilldict setValue:#"" forKey:[keys objectAtIndex:p]];
}
}
lblStudentName.text = [refilldict objectForKey:#"StudentName"];
lblStudentId.text = [refilldict objectForKey:#"StudentId"];
lblStudentAge.text = [refilldict objectForKey:#"StudentAge"];
lblStudentAddress.text = [refilldict objectForKey:#"StudentAddress"];
}
self.navigationController.navigationBar.userInteractionEnabled = YES;
[HUD hide:YES];
[HUD removeFromSuperview];
HUD=nil;
}

Answer 1

Please use the bellow code and pass your Initial Json dictionary in it.
-(void)parseJsonData:(NSDictionary *)jsonDictionary{
for(int i=0;i<[jsonDictionary allKeys].count;i++){
NSString *keyName = [[jsonDictionary allKeys] objectAtIndex:i];
id objValue = [jsonDictionary objectForKey:keyName];
if([objValue isKindOfClass:[NSArray class]]){
NSArray *dataList2Array = (NSArray *)objValue;
NSLog(#"DataList2 Is :--%#",dataList2Array);
}
else {
NSDictionary *dataList1 = (NSDictionary *)objValue;
NSLog(#"DataList1 Is :--%#",dataList1);
}
}
}

Answer 2

you can get easily like
[myArray addObject:[sdf objectForKey:#"DataList1"]];
its started with array of dictionary , so you need to store your second object to array and take from index.
NSArray *temp = [sdf objectForKey:#"DataList2"];
if(temp.count >0)
{
lblTeacherName.text = temp[0][#"TeacherName"];
lblTeacherId.text = temp[0][#"TeacherId"];
lblTeacherAge.text = temp[0][#"TeacherAge"];
lblTeacherAddress.text = temp[0][#"TeacherAddress"];
}
