导航控制器在popover [英] Navigation Controller in popover

问题描述

我是ipad应用程序开发中的一个新手。

我有兴趣创建一个应用程序，其中我有一个popover显示一个列表的项目。然后，我选择一个项目，并且视图演练到另一个表视图，包括另一个项目列表和导航返回按钮。

我将向下钻取的级别是动态的。

请指导我使用适当的资源来帮助我解决问题。

解决方案

我以前做过，效果很好！
只需将此函数分配给您的按钮（可能是UIBarButtonItem）：

  UIPopoverController * popover; 
 bool isPopoverOpen = false; 
  - （void）openPopover {
 if（！isPopoverOpen）{
 FirstViewController * firstViewCtrl = [[PartsViewCtrl alloc] init]; 
 UINavigationController * navbar = [[UINavigationController alloc] initWithRootViewController：firstViewCtrl]; 
 [firstViewCtrl release]; 
 navbar.contentSizeForViewInPopover = CGSizeMake（TABLE_WIDTH，TABLE_HEIGHT）; 
 popover = [[UIPopoverController alloc] initWithContentViewController：navbar]; 
 [navbar release]; 
 popover.delegate = self; 
 popover.popoverContentSize = CGSizeMake（TABLE_WIDTH，TABLE_HEIGHT）; 
 [popoverOnPartsView presentPopoverFromBarButtonItem：barButtonItem allowedArrowDirections：UIPopoverArrowDirectionAny animated：YES]; 
 isPopoverOpen = true; 
} else {
 [popover dismissPopoverAnimated：YES]; 
 [popover release]; 
 isPopoverOpen = false; 
} 
} 
  

将此函数实现到具有UITableView的FirstViewController：

   - （void）tableView :( UITableView *）tableView didSelectRowAtIndexPath :( NSIndexPath *）indexPath {
 SecondViewController * secondViewController = [[SecondViewController alloc] init]; 
 [self.navigationController pushViewController：secondViewController animated：YES]; 
 [secondViewController release]; 
} 
  

现在，您可以添加一个UITableView到SecondViewController，Too。并将其用于其他表格！

我希望它适用于您！

I am a total newbie in the ipad app development.

I am interested in creating an application where i have a popover showing a tableview with list of items. Then i select an item and the view drills to another tableview consisting of another list of items and a navigate back button as well.

the level to which i would be drilling down is dynamic.

Please guide me with appropriate resources to help me solve the problem.

解决方案

I did it before and it works well! Just assign this function to your button (perhaps an UIBarButtonItem):

UIPopoverController *popover;
bool isPopoverOpen = false;
-(void)openPopover{
    if(!isPopoverOpen){
        FirstViewController *firstViewCtrl = [[PartsViewCtrl alloc] init];
        UINavigationController *navbar = [[UINavigationController alloc] initWithRootViewController:firstViewCtrl];
        [firstViewCtrl release];
        navbar.contentSizeForViewInPopover = CGSizeMake(TABLE_WIDTH, TABLE_HEIGHT);
        popover = [[UIPopoverController alloc] initWithContentViewController:navbar];
        [navbar release];
        popover.delegate = self;
        popover.popoverContentSize = CGSizeMake(TABLE_WIDTH, TABLE_HEIGHT);
        [popoverOnPartsView presentPopoverFromBarButtonItem:barButtonItem permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
        isPopoverOpen = true;
    }else{
        [popover dismissPopoverAnimated:YES];
        [popover release];
        isPopoverOpen = false;
    }
}

And implement this function to FirstViewController which has an UITableView:

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
    SecondViewController *secondViewController = [[SecondViewController alloc] init];
    [self.navigationController pushViewController:secondViewController animated:YES];
    [secondViewController release];
}

Now you can add an UITableView to SecondViewController, Too. And use this scenario for other tables!

I hope it works for you!
