我正在使用带有ARC的XCode 4.5创建一个iPad版的Master Detail Application。 我设置了iPadMaster.h / .m(作为我的主人)和iPadDetailViewController.h / m(作为我的详细信息)。
当用户点击/选择iPadMaster上的行时,我试图从iPadDetailViewController加载不同的视图控制器。
我在iPadMaster.m上设置了这个:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
iPadDetailViewController * DVC = [[iPadDetailViewController alloc]initWithNibName:nil bundle:nil];
DVC.itemNumber = indexPath.row;
}
并在[viewDidLoad]
上的iPadDetailViewController.m上尝试了这个愚蠢的特技:
switch(_itemNumber)
{
case 0:
{
//Detail row
vc1 *viewController = [[vc1 alloc] init];
[self presentViewController:viewController animated:YES completion:nil];
break;
}
case 1:
{
//Report row
vc2 *viewController = [[vc2 alloc] init];
//viewController.somePassedInData = theDataToPass;
[self presentViewController:viewController animated:YES completion:nil];
break;
}
case 2:
{
//Report row
vc3 *viewController = [[vc3 alloc] init];
//viewController.somePassedInData = theDataToPass;
[self presentViewController:viewController animated:YES completion:nil];
break;
}
...
case 9:
{
//Report row
vc9 *viewController = [[vc9 alloc] init];
//viewController.somePassedInData = theDataToPass;
[self presentViewController:viewController animated:YES completion:nil];
break;
}
default:
{
break;
}
在iPhone上,我只会在- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
中涂抹“开关盒”,但我在iPad环境中迷失了......
提前完成了......

拆分视图控制器有一个属性viewControllers。索引1处的对象是细节控制器。您应该只创建一个viewControllers的可变副本,将索引1处的对象替换为新控制器,并将该数组设置为拆分视图的arrayControllers。
NextController *next = [[NextController alloc] init..... // or however you get your new controller
NSMutableArray *mut = [self.splitViewController.viewControllers mutableCopy];
[mut replaceObjectAtIndex:1 withObject:next];
self.splitViewController.viewControllers = mut;
