Read from plist insted of Code array

Question

Hi Guys

am Using UITableView - Searching table view

its really nice easy tutorial but i really have bad time try to read from plist

that what i did change

- (void)viewDidLoad {
[super viewDidLoad];

//Initialize the array.
listOfItems = [[NSMutableArray alloc] init];

TableViewAppDelegate *AppDelegate = (TableViewAppDelegate *)[[UIApplication sharedApplication] delegate];
listOfItems = [AppDelegate.data objectForKey:@"Countries"];

//Initialize the copy array.
copyListOfItems = [[NSMutableArray alloc] init];

//Set the title
self.navigationItem.title = @"Countries";

//Add the search bar
self.tableView.tableHeaderView = searchBar;
searchBar.autocorrectionType = UITextAutocorrectionTypeNo;

searching = NO;
letUserSelectRow = YES;

}

and This How i read plist from My AppDelegate.m

- (void)applicationDidFinishLaunching:(UIApplication *)application {

NSString *Path = [[NSBundle mainBundle] bundlePath];
NSString *DataPath = [Path stringByAppendingPathComponent:@"Data.plist"];

NSDictionary *tempDict = [[NSDictionary alloc] initWithContentsOfFile:DataPath];
self.data = tempDict;
[tempDict release];


// Configure and show the window
[window addSubview:[navigationController view]];
[window makeKeyAndVisible];

}

and this my plist

  <plist version="1.0">
<dict>
    <key>Countries</key>
    <array>
        <array>
            <string>USA</string>
        </array>
        <array>
            <string>UK</string>
        </array>
    </array>
</dict>
</plist>

and i get this error

* Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* -[NSCFArray objectForKey:]: unrecognized selector sent to instance 0xe09120'

help please am stock with this

Answer 1

This assigns a newly allocated mutable array to a member.

listOfItems = [[NSMutableArray alloc] init];

This leaks the above array and assigns an autoreleased, immutable array to the member.

listOfItems = [AppDelegate.data objectForKey:@"Countries"];

Later, when you access listOfItems, it may have been released. Use this:

[listOfItems addObjectsFromArray:[AppDelegate.data objectForKey:@"Countries"]];

This all assumes that [AppDelegate.data objectForKey:@"Countries"] is returning an array. Given the plist, it should, but it is worth double checking.

Answer 2

did you figure this out yet? I'm having a similar problem trying to use a plist for that tutorial.

thanks
