在UITableView中查看plist数据

Question

The thing is. i want to display the each object to the tableview not it's under subs so in this case. 123. i can't seem to figured out how to display the that one item... also. the way it saves the plist now it overwrites the plist it seems. since it's fresh created each time i go add i followed numbers torturials on the web and here on stack overflow. but none seem to get close to what i want to do.

MainTableViewController.h

{
NSMutableDictionary *arrayD;
}

MainTableViewController.m

 - (void)viewDidLoad
{
[super viewDidLoad];


// Property List.plist code
//Gets paths from root direcory.
NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES);
//Get documents path.
NSString *documentsPath = [paths objectAtIndex:0];

//Get the path to our PList file.
NSString *plistPath = [documentsPath stringByAppendingPathComponent:@"Servers.plist"];

//Check to see if Property List.plist exists in documents.
if (![[NSFileManager defaultManager] fileExistsAtPath:plistPath]){
    [[NSFileManager defaultManager]copyItemAtPath:[[NSBundle mainBundle]pathForResource:@"Servers" ofType:@"plist"] toPath:plistPath error:nil];
    //If not in documents, get property list from main bundle.
//        plistPath = [[NSBundle mainBundle] pathForResource:@"Servers" ofType:@"plist"];

}

//Read property list into memory as an NSData object.
NSData *plistXML = [[NSFileManager defaultManager] contentsAtPath:plistPath];

NSString *errorDesc = nil;

NSPropertyListFormat format;

//convert static property list into dictionary object.
NSDictionary *temp = (NSDictionary *)[NSPropertyListSerialization propertyListFromData:plistXML mutabilityOption:NSPropertyListMutableContainersAndLeaves format:&format errorDescription:&errorDesc];

    if (!temp){
        NSLog(@"Error reading plist: %@, format: %d", errorDesc, format);
            }

    //Display values.
NSMutableDictionary *dictinoary =[[NSMutableDictionary alloc] initWithContentsOfFile:plistPath];

tableData = [dictinoary objectForKey:@"Hostname"];
NSLog(@"Count: %i", [arrayD count]);

}

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

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

    {
    static NSString *cellIdentifier = @"Hostname";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];

if (cell == nil) {

        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];

}

cell.textLabel.text = [tableData objectAtIndex:indexPath.row];

return cell;

}

AddServerViewController.m

    - (IBAction)SaveData:(id)sender {
//Get paths from root direcory.
NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES);
//Get documents path.
NSString *documentsPath = [paths objectAtIndex:0];

//Get the path to our PList file.
NSString *plistPath = [documentsPath stringByAppendingPathComponent:@"Servers.plist"];

//Set the variables to the values in the text fields.
hostName = hostEntered.text;
portNumber = portEntered.text;
userName = userNameEntered.text;
passWord = passWordEntered.text;

NSMutableDictionary *rootObj = [NSMutableDictionary dictionaryWithCapacity:4];
NSMutableDictionary *data;
data = [NSMutableDictionary dictionaryWithObjects:[NSArray arrayWithObjects: hostName, portNumber, userName, passWord, nil]                                      forKeys:[NSArray arrayWithObjects:@"Hostname", @"Port", @"Username", @"Password", nil]];
[rootObj setObject:data forKey:hostName];


NSString *error = nil;

//Create NSData from dictionary.
NSData *plistData = [NSPropertyListSerialization dataFromPropertyList:rootObj format:NSPropertyListXMLFormat_v1_0 errorDescription:&error];

//Check is plistData exists.
if(plistData){

    //Write plistData to our Properity List.plist file.
    [plistData writeToFile:plistPath atomically:YES];

}
else{
    NSLog(@"Error in saveData: %@", error);
}

}

Answer 1

Each dictionary has allKeys method that returns an array with... all keys. If you do what Peter said and then you can just populate your tableView with allKeys

Answer 2

Forgive me if I misread your question but the following was done after recreating your plist:

NSString *path = [[NSBundle mainBundle] pathForResource:@"Sample List" ofType:@"plist"];
NSDictionary *plistDict = [NSDictionary dictionaryWithContentsOfFile:path];

NSLog(@"Plist dict %@", [plistDict objectForKey:@"123"]);

That would output:

Plist dict {
    Hostname = 123;
    Password = 123;
    Port = 123;
    Username = 123;
}

Is that what you were looking for? If not, ill need a bit more detail with regards to what it is that you're looking for.
