Creating Drill-Down Detail UITableView from JSON NSDictionary
- by Michael Robinson
I'm have a load of trouble finding out how to do this,
I want to show this in a UITableDetailView (Drill-Down style) with each item in a different cell. All of the things I've read all show how to load a single image on the detail instead of showing as a UITableView. Does the dictionary have to have "children" in order to load correctly? Here is the code for the first view creating *dict from the JSON rowsArray.
I guess what I'm looking for is what to put in the FollowingDetailViewController.m to see the rest of *dict contents, so when selecting a row, it loads the rest of the *dict.
I have rowsArray coming back as follows:
'{ loginName = Johnson;
memberid = 39;
name = Kris;
age = ;}, etc,etc...
Thanks,
// SET UP TABLE & CELLS
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
}
NSDictionary *dict = [rowsArray objectAtIndex: indexPath.row];
cell.textLabel.text = [dict objectForKey:@"name"];
cell.detailTextLabel.text = [dict objectForKey:@"loginName"];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
return cell;
}
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
- (void)viewDidLoad {
[super viewDidLoad];
//GET JSON FROM WEBSERVICES:
NSURL *url = [NSURL URLWithString:@"http://10.0.1.8/~imac/iphone/jsontest.php"];
NSString *jsonreturn = [[NSString alloc] initWithContentsOfURL:url];
NSData *jsonData = [jsonreturn dataUsingEncoding:NSUTF32BigEndianStringEncoding];
NSError *error = nil;
NSDictionary * dict = [[CJSONDeserializer deserializer] deserializeAsDictionary:jsonData error:&error];
if (dict)
{
rowsArray = [dict objectForKey:@"member"];
[rowsArray retain];
}
[jsonreturn release];
}
//GO TO DETAIL VIEW:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
FollowingDetailViewController *aFollowDetail = [[FollowingDetailViewController alloc] initWithNibName:@"FollowingDetailView" bundle:nil];
[self.navigationController pushViewController:aFollowDetail animated:YES];
}
