UITableView (without using a navigation template), getting specific data from plist

Question

I use the example on page 210 of the book “iPhone Design” (“Exploring the iPhone SDK”) and it looks like what I want to do, but this specific example is complicated by the use of partitions in TableView. I have a specific hierarchy in my plist ...

Root  ---- Dictionary
        Rows  ---- Array
                Item 0- Dictionary
                        fullName  ---- String
                        address   ---- String
                Item 1   ---- Dictionary
                        fullName  ---- String
                        address   ---- String

So, I have a UITableView that takes up a small portion of the view on this “screen”. The rest of the view has other elements, so I selected a nut to use the navigation template.

The code I use does not match, because I really don’t understand which fields to call.

Can someone show me a VERY simple example of how I could list all the "firstNames" in this table. If something is wrong with my plist, please let me know what will change.

In a nutshell, I want to iterate over all the Item # dictionaries to list all the first names. My project is like a contact list, but not exactly a contact list.

Right now I'm using this code that just displays the word "Lines". I changed the lines of words to Rows1 in my plist and found that it captures this "array element". I hope I said the right thing.

-(void)viewDidLoad {    
    NSString *path = [[NSBundle mainBundle] pathForResource:@"data" ofType:@"plist"];

    NSDictionary *dict = [[NSDictionary alloc] initWithContentsOfFile:path];
    self.names = dict;
    [dict release];

    NSArray *array = [[names allKeys] sortedArrayUsingSelector:@selector(compare:)];
    self.listData = array;

    [super viewDidLoad];
}

 

-(NSInteger)tableView:(UITableView *)tableView
 numberOfRowsInSection:(NSInteger)section {
    return [self.listData count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView
         cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *SimpleTableIdentifier = @"Identifier";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:SimpleTableIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:SimpleTableIdentifier] autorelease];
    }

    NSUInteger row = [indexPath row];
    cell.textLabel.text = [listData objectAtIndex:row];
    return cell;
}

I tried the web for several days trying to find a simple example that uses the plist hierarchy to list items in a table that is not part of the navigation template.

Many thanks

, . plist.

plist:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

</array>
</plist>

plist:

NSString* plistPath = [[NSBundle mainBundle] pathForResource:@"contacts" ofType:@"plist"];
contacts = [[NSArray arrayWithContentsOfFile:plistPath] retain];

:

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    return 1;
}


// Customize the number of rows in the table view.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return [contacts count];
}


// 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] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
    }

    NSDictionary *dict = [contacts objectAtIndex:indexPath.row];
    cell.textLabel.text = [NSString stringWithFormat:@"%@ %@", [dict objectForKey:@"name"], [dict objectForKey:@"familyname"]];

    return cell;
}

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


    DetailContactViewController *detailViewController = [[DetailContactViewController alloc] initWithNibName:@"DetailContactView" bundle:nil];
    detailViewController.contact = [contacts objectAtIndex:indexPath.row];
    // ...
    // Pass the selected object to the new view controller.
    [self.navigationController pushViewController:detailViewController animated:YES];

    [detailViewController release];
