in Split view controller didSelect method not working

问题

i am working on splitviewcontroller in window based application im writing code as follows but didselect not working

in LeftViewController.h:

#import <UIKit/UIKit.h>
@class RightViewController;
@interface LeftViewController : UITableViewController
{
    RightViewController *details;
}
@property (retain, nonatomic) NSNumber *detailItem;

@end

InLeftviewController.m: didselectmethod:

- (void)tableView:(UITableView *)tableView didDeSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    RightViewController *rightViewController = [[RightViewController alloc] initWithNibName:@"RightViewController" bundle:nil];
    [self.navigationController pushViewController:rightViewController animated:YES];

    NSUInteger item = [indexPath row];
    rightViewController.detailItem = [NSNumber numberWithInteger:item];
    rightViewController.detailItem = detailItem;
    NSLog(@"detailItem= %@ , %@", detailItem,rightViewController.detailItem );

    int i = [detailItem intValue];
    if(detailItem == [NSNumber numberWithInt:0])
    {
        //Adding label to the details view
        UILabel *infoLabel = [[UILabel alloc]initWithFrame:CGRectMake(5, 5, 450, 150)];
        infoLabel.text = @"Customer:Barrick Gold\r\nMine:Turquiose Ridge Mine \r\nLocation:Mesa, AZ";
        [rightViewController.view addSubview:infoLabel];

        //Adding table view to the details view
        UITableView *mapTable = [[UITableView alloc]initWithFrame:CGRectMake(165, 5, 450,150) style:UITableViewStyleGrouped];
        [rightViewController.view addSubview:mapTable];
    }

    if(item == 1)
    {
        UILabel *infoLabel = [[UILabel alloc]initWithFrame:CGRectMake(5, 5, 450, 150)];
        infoLabel.text = @"Eqipement";

    }

    if(i == 2)
    {

    }
}

回答1:

I am not sure what you are trying here. If the LeftViewController and RightViewController are the master and detail views of the split view then why are you trying to push the detail view from the master view. The function of the split view is to show the details of the selected item in the master view(left view) on the detail view on the right side(detail view). So why would you bother pushing that view in the master view. All you have to do is to set the detail item for the DetailViewController.

回答2:

Try to add the line at the end of didSelect method of tableview in leftView controller[self.navigationController pushViewController:rightViewController animated:YES];
