在两个表视图之间传递数据

Question

What I am trying to do is .. i want to pass the data between two table views.

In my root view controller I am using an array and then populating it for the RootViewController and in

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

method I am doing this:

if (indexPath.row == 0)
    {
        self.schedule.title = @"Show1";
        NSLog(@"SCHEDULE CONTROLLER TITLE = %@", schedule.title);
        NSLog(@"FIRST ROW ");
    }
    if (indexPath.row == 1) {
        self.schedule.title = @"Show2";
        NSLog(@"SECOND ROW");
    }
    if(indexPath.row == 2){
        self.schedule.title = @"Show3";
        NSLog(@"THIRD ROW");
    }

    schedule = [[ScheduleViewController alloc] initWithNibName:@"ScheduleViewController" bundle:nil];
    [self.navigationController pushViewController:schedule animated:YES];

schedule is another table view so.. what I am doing is I am comparing the titile of schedule to decide the contents of schedule table view, but some how it is not getting the data.

here is ViewDidLoad method of schedule view:

 [super viewDidLoad];

    if ([self.title isEqualToString:@"Show1"])
    {
        showSchedule = [[NSArray alloc] initWithObjects:@"SUNDAY",@"MONDAY",@"TUESDAY" , nil];
    }
    if ([self.title isEqualToString:@"Show2"])
    {
        showSchedule = [[NSArray alloc] initWithObjects:@"WEDNESDAY",@"THURSDAY",@"FRIDAY" , nil];
    }else {
        showSchedule = [[NSArray alloc] initWithObjects:@"SATURDAY", nil];
    }

    [self.tableView reloadData];

The self.title is returning null and therefore it goes into the else loop at the end. Any ideas what I am doing wrong here.. ?

Thanks for your time in advance

Answer 1

try this.

if ([self.title isEqualToString:@"Show1"])
     {

replace this line.

if ([ self.navigationItem.title isEqualToString:@"Show1"])
   {

Then try

Answer 2

在分配视图之前添加标题...

Answer 3

set your title after alloc the controller

NSString *titleOfTableVC ;

if (indexPath.row == 0)
{
    titleOfTableVC = @"Show1";
    NSLog(@"SCHEDULE CONTROLLER TITLE = %@", titleOfTableVC );
    NSLog(@"FIRST ROW ");
}
if (indexPath.row == 1) {
    titleOfTableVC = @"Show2";
    NSLog(@"SECOND ROW");
}
if(indexPath.row == 2){
    titleOfTableVC = @"Show3";
    NSLog(@"THIRD ROW");
}

schedule = [[ScheduleViewController alloc] initWithNibName:@"ScheduleViewController" bundle:nil];
schedule.title =  titleOfTableVC ;    
[self.navigationController pushViewController:schedule animated:YES];

Hope this will make u understand
