Answer 1

Write in your "secondViewConroller.h" file

@property (nonatomic, Strong) NSMutableDictionary *json;

And pass it as in "firtstViewConroller.m"

NSMutableDictionary *temJSONDic = ....

secondViewConroller *FVC = [[secondViewConroller alloc] initWithNibName:@"secondViewConroller" bundle:nil];
FVC.json = temJSONDic;
[self.navigationController pushViewController:FVC animated:YES];

Use below code to load your xib file using [NSBundle mainBundle] approach and the first object in returned array is your controller. Then assign your dictionary object and then push using navigationcontroller .

    NSArray * array = [[NSBundle mainBundle] loadNibNamed:@"<your xib file name without .xib extension>" owner:self options:nil];
secondViewConroller *cntrl = [array objectAtIndex:0];
cntrl.json = <your dictionary data>;
[self.navigationController pushViewController:cntrl animated:YES];
