I have a plist with Dictionary and numbers of strings per dictionary.show into the url below.and this list of items is in thousands in the plist.

Now want to display these list into the tableview

now how can i display this plist into the UITableView

what I am trying is:

- (id)readPlist:(NSString *)fileName 
{

NSString *error;
NSPropertyListFormat format;
id plist;

NSString *localizedPath = [[NSBundle mainBundle] pathForResource:@"A" ofType:@"plist"];

dic =[NSDictionary dictionaryWithContentsOfFile:localizedPath];



plist = [NSPropertyListSerialization propertyListFromData:dic mutabilityOption:NSPropertyListImmutable format:&format errorDescription:&error];
if (!plist) {
    NSLog(@"Error reading plist from file '%s', error = '%s'", [localizedPath UTF8String], [error UTF8String]);
    [error release];
}

return plist;
}


- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{

dict =[self readPlist:@"A"];
return dict.allKeys.count;
 }

 - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
 {

dict = [self readPlist:@"A"];
 key = [dict.allKeys objectAtIndex:section];
return [[dict valueForKey:key] count];

}

- (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];
}

  cell.textLabel.text = [[dict objectForKey:key] objectAtIndex:indexPath.row];

return cell;
}

UPDATE 2: You need to set the delegate and datasource for your tableView in your xib or ViewController.

In your ViewController.h file

@interface ViewController:UIViewController <UITableViewDelegate, UITableDataSource>

Try this code which I have written for you.

- (void)viewDidLoad {

    tableView.delegate = self;
    tableView.dataSource = self;

    NSString *path = [[NSBundle mainBundle] pathForResource:@"Filename" ofType:@"plist"];
    NSArray *contentArray = [NSArray arrayWithContentsOfFile:path];
    // Having outlet for tableArray variable.
    tableArray = [[NSMutableArray alloc]initWithArray:contentArray copyItems:YES];

    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.
}

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    return [tableArray count];
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
   // In your case dictionary contains strings with keys and values. The below line returns dictionary only. not array..
    NSDictionary *dictionary = [tableArray objectAtIndex:section];
    return dictionary.allKeys.count;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *cellIdentifier = @"MyCell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:cellIdentifier];
    }
    NSDictionary *dictionary = [tableArray objectAtIndex:indexPath.section];
    NSArray *keysArray = dictionary.allKeys;
    // This below line display the key in textLabel
    cell.textLabel.text = [keysArray objectAtIndex:indexPath.row];
    // Below line will display the value of a key in detailTextLabel.
    cell.detailTextLabel.text = [dictionary valueForKey:[keysArray objectAtIndex:indexPath.row]];
    return cell;
}

UPDATE 2: After I have seen your plist in my MAC, I have found out that we are working with array of dictionaries in your A.plist.

So I found there is a bug in our code itself. Not in the plist file and you can use your 8000 data plist too.. Its working too. I have checked out totally. Now you can get the above Code and start work with.

回答2:

store Plist data in array

- (id)readPlist:(NSString *)fileName 
{

NSString *error;
NSPropertyListFormat format;
id plist;

NSString *localizedPath = [[NSBundle mainBundle] pathForResource:@"A" ofType:@"plist"];

// declare your array in .h file
  array = [NSArray arrayWithContentsOfFile:localizedPath];    

plist = [NSPropertyListSerialization propertyListFromData:dic mutabilityOption:NSPropertyListImmutable format:&format errorDescription:&error];
if (!plist) {
    NSLog(@"Error reading plist from file '%s', error = '%s'", [localizedPath UTF8String], [error UTF8String]);
    [error release];
}

return plist;
}

and then write it in table

- (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];
}

  cell.textLabel.text = [array objectAtIndex:indexPath.row] valueForKey:@"keyname"];;

return cell;
}
