ios - 在 objective-c 的 tableViewController 中显示 NSMutabelArray

Question

我将 NSMutableArray 传递给另一个 TableView ，我想在 TableView 中显示它。我的NSMutableArray如下

    "Dining Table.png",

    "TV.png",
    "Curtains.png",
    "Refrigerator.png",
    "Water Heater.png",
    "Microwave Oven.png"
)

我将数据发送为，

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([segue.identifier isEqualToString:@"segue"]) {
    MZFormSheetPresentationViewControllerSegue *presentationSegue = (id)segue;
    presentationSegue.formSheetPresentationController.presentationController.shouldApplyBackgroundBlurEffect = YES;
    UINavigationController *navigationController = (id)presentationSegue.formSheetPresentationController.contentViewController;
    AmennitiesTableTableViewController *presentedViewController = [navigationController.viewControllers firstObject];
//        presentedViewController.textFieldBecomeFirstResponder = YES;

    presentedViewController.passingString = facilities;

}

并在 TableView Controller 中接收数据，

- (void)viewDidLoad {
    [super viewDidLoad];

    self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Close" style:UIBarButtonItemStylePlain target:self action:@selector(close)];

    NSLog(@"%@",self.passingString);
    [self.tableView reloadData];

}

我尝试如下显示可变数组，

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *cellIdentifier = @"facilitiesCell";
    AmenitiesTableCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
    cell.facilitylbl.text = [self.passingString objectAtIndex:indexPath.row];

    // Configure the cell...

    return cell;
}

但我不明白在表格 View 上填充数据到底缺少什么。

我认为您缺少设置 TableView 委托(delegate)和数据源。

- (void)viewDidLoad {
    [super viewDidLoad];

    self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Close" style:UIBarButtonItemStylePlain target:self action:@selector(close)];
    [self.myTable setDelegate:self];
    [self.myTable setDataSource:self];

    NSLog(@"%@",self.passingString);
   [self.tableView reloadData];

}

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
   // Return the number of sections.
   return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
   // Return the number of rows in the section.
    return self.passingString.count;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *cellIdentifier = @"facilitiesCell";
   AmenitiesTableCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];

    if(self.passingString.count > 0){
        cell.facilitylbl.text = [self.passingString objectAtIndex:indexPath.row];
     }

// Configure the cell...

    return cell;
}
