call NSDictionary in current view controller - iphone

Question

i have an function in which i am calling values from dictionary that is defined in other view controller. I have to call this method in view didload method of current view controller.
here is my code:
-(void)setData:(NSDictionary *)dic {
self.jsonLabel.text = [dic objectForKey:#"Description"];
self.jsonImage.image = [UIImage imageWithData: [NSData dataWithContentsOfURL: [NSURL URLWithString: [dic objectForKey:#"PictureURL"]]]];}

Answer 1

Try this
NSURL *jsonURL = [NSURL URLWithString:[jsonItem objectForKey:#"PictureURL"]];
Update:
See you allocate the dictionary while the second View controller inside its alloc init method.
Then you can pass the dictionary from the first view controller as
secondViewController.dict = self.dict;
Then you push the second view controller. Check the value of the dictionary in viewDidLoad: Then you can proceed if the dictionary is available.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
//make sure jscontroller is allocated before this point.
NSDictionary *tempDict = [[NSDictionary alloc]init];
// set tempDict here with value or object aBook.PictureURL.
jscontroller.jsonItem = tempDict;
[tempDict release];
NSLog(#"json ndic.......%#", jscontroller.jsonItem);
[self.navigationController pushViewController:jscontroller animated:YES];
}

Answer 2

If viewControllerObject is the necessary object of the view controller that defines this function then allocate the object and call like this
- (void)viewDidLoad {
[viewControllerObject setData:urDict];
}

Answer 3

I was using this code in otherviewcontroller
and trying to retrieve in currentViewController
(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
JSONViewController *controller = [[JSONViewController alloc] initWithNibName:#"JSONView" bundle:nil];
EmpDictionary=[[NSMutableDictionary alloc]init];
[EmpDictionary setValue:aBook.Description forKey:#"Description"];
[EmpDictionary setValue:aBook.PictureURL forKey:#"PictureURL"];
[EmpDictionary setValue:aBook.WeatherID forKey:#"WeatherID"];
EmpArray=[[NSMutableArray alloc]init];
[EmpArray addObject:EmpDictionary];
NSDictionary *itemAtIndex = [self.EmpArray objectAtIndex:indexPath.row];
[self.navigationController pushViewController:controller animated:YES];
[controller setData:itemAtIndex];}
