Question

开发完整的C.R.U.D.远程数据库上的应用程序。我的应用程序在发布此问题时正常工作。不过我想提前一点。我是IOS开发的新手。从我的代码中可以看出，我获取了valueForKey名称并在tableview中显示它。单击该名称将使您在文本字段中显示名称。但是我想得到以下键的valueForKey：namesid，address1，address2，address3，address4，email，mobile，telephone和comment，并显示它们的名称，所有值都将显示在它们自己的文本字段中。

- (void)requestFinished:(ASIHTTPRequest *)request
{
//Enable the Reload Button.
self.navigationItem.leftBarButtonItem.enabled = YES;
//Enable the Add Contact Detail Button.
self.navigationItem.rightBarButtonItem.enabled = YES;

searchBar.hidden = NO;

SBJsonParser *parser = [[SBJsonParser alloc] init];

if (request.responseStatusCode == 200) {

    [self.activityIndicator stopAnimating];

    NSString *json_string = [request responseString];

    // Actually parsing the JSON
    NSArray *statuses = [parser objectWithString:json_string error:nil];

    for (NSDictionary *status in statuses){
        @try {

            [remotecontacts addObject:[status valueForKey:@"name"]];

        }
        @catch (NSException *exception) {

            [remotecontacts addObject:[NSString stringWithFormat:@""]];

        }

    } // end for

    NSDictionary *remotecontactsInDict = [NSDictionary dictionaryWithObject:remotecontacts forKey:@"Contacts"];

    [listOfItems addObject:remotecontactsInDict];

    [self.myTableViewController reloadData];


} else {

    //Enable the Reload Button.
    self.navigationItem.leftBarButtonItem.enabled = YES;
    //Enable the Add Contact Details Button.
    self.navigationItem.rightBarButtonItem.enabled = YES;

    //Stop the Activity Indicator.
    [self.activityIndicator stopAnimating];

    UIAlertView *myAlert = [[UIAlertView alloc]initWithTitle:@"Error"   message:@"Unexpected error, please try again later!"delegate:self cancelButtonTitle:@"Ok"otherButtonTitles:nil];
    [myAlert show];
    [myAlert release];
    return;
}


}

// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:     (NSIndexPath *)indexPath {

static NSString *CellIdentifier = @"Cell";

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
    cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
}

// Set up the cell...

if(searching) 
    cell.text = [copyListOfItems objectAtIndex:indexPath.row];
else {

    //First get the dictionary object
    NSDictionary *dictionary = [listOfItems objectAtIndex:indexPath.section];

    NSArray *array = [dictionary objectForKey:@"Contacts"];
    NSString *cellValue = [array objectAtIndex:indexPath.row];
    cell.text = cellValue;

}

return cell;

}

// Customize the number of rows in the table view.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {

if (searching)
    return [copyListOfItems count];
else {

    //Number of rows it should expect should be based on the section
    NSDictionary *dictionary = [listOfItems objectAtIndex:section];
    NSArray *array = [dictionary objectForKey:@"Contacts"];
    return [array count];

}

}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

//Get the selected country

NSString *selectedCountry = nil;

if(searching)
    selectedCountry = [copyListOfItems objectAtIndex:indexPath.row];
else {

    NSDictionary *dictionary = [listOfItems objectAtIndex:indexPath.section];
    NSArray *array = [dictionary objectForKey:@"Contacts"];
    selectedCountry = [array objectAtIndex:indexPath.row];
}

//Initialize the detail view controller and display it.
DetailViewController *dvController = [[DetailViewController alloc] initWithNibName:@"DetailView" bundle:[NSBundle mainBundle]];
dvController.selectedCountry = selectedCountry;
[self.navigationController pushViewController:dvController animated:YES];
[dvController release];
dvController = nil;

}

我强烈建议您查看Sensible TableView框架。框架将自动获取远程数据并将其显示在表视图中。与手动操作相比，节省了大量时间。
