pass NSMutableArray to UITableViewController

Question

I have UIViewController that contains NSMutableArray , I want to pass this array to UITableViewController and view it on the table .. how can I do that ??

I mean I want to (pass) NSMutableArray or any Variable from UIViewController to UITableViewController not (create) a table

I want to pass newBooksArray to UITableViewController, I wrote in UIViewController:

mytable.gettedBooks = newBooksArray; // gettedBooks is NSMutableArray in UITableViewController

mytable.try = @"Emyyyyy"; // try is a NSString in UITableViewController

and in UITableViewController in DidloadView i wrote

NSLog(@"Try: %@", try); // out is null
NSLog(@"my getted array count: %d", [gettedBooks count]); // out is 0

any help ???

Answer 1

Creating a UITableView and filling with an array

I created the above tutorial specially for this problem.

There are also more methods you can learn about on the developer documents

Firstly, you want to make sure you have the required delegate calls in your @interface:

@interface RootViewController : UIViewController <UITableViewDataSource, UITableViewDelegate>
{
    NSMutableArray         * feed;
    UITableView            * tableView;
}

You want something similar to the following in your controller:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return [feed 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 = [mutableArray objectAtIndex:indexPath.row];
    return cell;
}

numberOfRowsInSection makes sure you actually load the required number of cell rows from your NSMutableArray. And cellForRowAtIndexPath actually loads the content from each row of your NSMutableArray into each row of the UITableView.

For passing it to another controller, don't you want something like this?

UITableViewController *viewController = [[UITableViewController alloc] initWithNibName:@"TableXIB" bundle:nil];
[viewController setGettedBooks:newBooksArray];
[self.navigationController pushViewController:viewController animated:YES];

If you are using a Tab Bar controller, and First View controller is table view controller and second is UIView controller. You can Pass data to Table View controller by followoing code segment. You need to declare variable called arrayData (NSMutableArray) in table view controller and set property (Since we need to access this from another class.) From this arrayData, you need to load data in tableView. In View controller class write following code.

    NSArray *viewControllers = [self.tabBarController viewControllers];
    MyTableViewController *mTable = [viewControllers objectAtIndex:0];

    [mTable SetArrayData:arrayFromViewController];

    [mTable.tableView reloadData];

If you are using Navigation controller, you can do

    NSArray *viewControllers = [self.navigationController viewControllers];
    MyTableViewController *mTable = [viewControllers objectAtIndex:0];

    [mTable SetArrayData:arrayFromViewController];

    [mTable.tableView reloadData];

Optionally you can use delegates.
