View plist data in UITableView - ios

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.

if (!temp){

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

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.
