iOS使用数组添加到UITableView

Question

好的，我想在表格视图中添加一行。 我一定做错了。 我要添加到数组中，是否缺少使用新数组刷新UITableView的功能？

#import "RootViewController.h"
#import "DetailViewController.h"
@implementation RootViewController
@synthesize toolbar;
@synthesize window;

#pragma mark -
#pragma mark View lifecycle


- (void)viewDidLoad {
    //theArray = [[NSArray alloc] initWithObjects:@"Apple",nil];
    theArray = [[NSMutableArray alloc] init];


    [super viewDidLoad];

    [window addSubview:[navigationController view]];
    [window addSubview:toolbar];
    [window makeKeyAndVisible];
    // Uncomment the following line to display an Edit button in the navigation bar for this view controller.
    // self.navigationItem.rightBarButtonItem = self.editButtonItem;
}



#pragma mark -
#pragma mark Table view delegate

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    NSString *selectedTask = [theArray objectAtIndex:indexPath.row];
    DetailViewController *dvController = [[DetailViewController alloc] initWithNibName:@"DetailView" bundle:[NSBundle mainBundle]];
    dvController.selectedTask = selectedTask;
    [self.navigationController pushViewController:dvController animated:YES];
    [dvController release];
    dvController = nil;

}



- (void)didReceiveMemoryWarning {
    // Releases the view if it doesn't have a superview.
    [super didReceiveMemoryWarning];

    // Relinquish ownership any cached data, images, etc that aren't in use.
}

- (void)viewDidUnload {
    // Relinquish ownership of anything that can be recreated in viewDidLoad or on demand.
    // For example: self.myOutlet = nil;
}


- (void)dealloc {
    [super dealloc];
}


@end

当我环顾四周并看到将数组推向表格视图时，您的帮助将不胜感激，但进一步的研究使我陷入了困境。

假设您已正确定义所有UITableViewDataSource方法，则可能只需要在UITableView上调用reloadData。 有关reloadData方法的详细信息，请参见UITableView参考。
