Iphone 选择行以更改视图

我已经创建了视图控制器，并附加这些控制器来控制各自的视图。但是，我不知道如何使以下代码进入正确的视图（在根视图控制器中）：

每次我选择表中的任何一行时，所有视图都会出现。我如何安排它们只打开它应该打开的视图？

问题是您在每个视图控制器上调用

pushViewController:animated

。如果您只想显示一个视图控制器，只需对所需的视图控制器调用

pushViewController:animated

。以下是一个示例：

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

    // This code shows a different view depending on the selected row.
    UIViewController *viewController = nil;
    switch (indexPath.row) {
        case 0:
            viewController = [[RunViewController alloc] initWithNibName:@"RunView" bundle:[NSBundle mainBundle]];
            break;

        case 1:
            viewController = [[CalcViewController alloc] initWithNibName:@"CalcView" bundle:[NSBundle mainBundle]];
            break;

        case 2:
            viewController = [[PushViewController alloc] initWithNibName:@"PushView" bundle:[NSBundle mainBundle]];
            break;

        case 3:
            viewController = [[SitViewController alloc] initWithNibName:@"SitView" bundle:[NSBundle mainBundle]];
            break;

        case 4:
            viewController = [[TimerViewController alloc] initWithNibName:@"TimerView" bundle:[NSBundle mainBundle]];
            break;
    }

    if (viewController != nil) {
        [self.navigationController pushViewController:viewController animated:YES];
        [viewController release];
    }

}

问题在于，您正在对每个视图控制器调用

pushViewController:animated

。如果您只想显示一个视图控制器，只需对所需的视图控制器调用

pushViewController:animated

。以下是一个示例：

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

    // This code shows a different view depending on the selected row.
    UIViewController *viewController = nil;
    switch (indexPath.row) {
        case 0:
            viewController = [[RunViewController alloc] initWithNibName:@"RunView" bundle:[NSBundle mainBundle]];
            break;

        case 1:
            viewController = [[CalcViewController alloc] initWithNibName:@"CalcView" bundle:[NSBundle mainBundle]];
            break;

        case 2:
            viewController = [[PushViewController alloc] initWithNibName:@"PushView" bundle:[NSBundle mainBundle]];
            break;

        case 3:
            viewController = [[SitViewController alloc] initWithNibName:@"SitView" bundle:[NSBundle mainBundle]];
            break;

        case 4:
            viewController = [[TimerViewController alloc] initWithNibName:@"TimerView" bundle:[NSBundle mainBundle]];
            break;
    }

    if (viewController != nil) {
        [self.navigationController pushViewController:viewController animated:YES];
        [viewController release];
    }
