Objective c UITableView-点击单元格并获取下一个视图

在TableViewController中输入下一个视图时遇到问题。 当我点击单元格时，我会看到NSLog文本，但没有操作，也没有第二视图。 这意味着程序输入方法，但不执行任何操作。什么是我的错？ 我正在四处测试，没有得到任何解决方案

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

    if (indexPath.row==0) {
        NSLog(@"Index 0");
        AudioViewController *audioviewcontroller = [[AudioViewController alloc] initWithNibName:@"AudioViewController" bundle:nil];
        [self.navController pushViewController:audioviewcontroller animated:YES];
        [audioviewcontroller release];
        [tableView deselectRowAtIndexPath: indexPath animated:YES];

    }
    if (indexPath.row==1) {
        NSLog(@"Index 1");
        DisplayViewController *displayviewcontroller = [[DisplayViewController alloc] initWithNibName:@"DisplayViewController" bundle:nil];
        [self.navController pushViewController:displayviewcontroller animated:YES];
        [displayviewcontroller release];
        [tableView deselectRowAtIndexPath: indexPath animated:YES];
    }
    if (indexPath.row==2) {
        LichtViewController *lichtviewcontroller = [[LichtViewController alloc] initWithNibName:@"LichtViewController" bundle:nil];
        [self.navController pushViewController:lichtViewController animated:YES];
        [lichtviewcontroller release];
        [tableView deselectRowAtIndexPath: indexPath animated:YES];
        NSLog(@"Index 2");
    }
    if (indexPath.row==3) {
        NSLog(@"Index 3");
        ProjektorViewController *projektorviewcontroller = [[ProjektorViewController alloc] initWithNibName:@"ProjektorViewController" bundle:nil];
        [self.navController pushViewController:projektorviewcontroller animated:YES];
        [tableView deselectRowAtIndexPath: indexPath animated:YES];
        [projektorviewcontroller release];

    }
}

此外，我尝试了以下代码：

UIView *currentView = self.view;    
UIView *theWindow = [currentView superview];
[currentView removeFromSuperview];      
UIView* audioView= audioviewcontroller.view;        
[theWindow addSubview:audioView];       
[self.navController pushViewController:audioviewcontroller animated:YES];       [audioviewcontroller release];
[tableView deselectRowAtIndexPath: indexPath animated:YES]; 

我没有收到任何警告，但出现崩溃，调试器控制台显示：

提前感谢您的帮助

与视图控制器关联的导航控制器的代理是

self.navigationController

，当您将视图控制器推到其上时，是否检查该代理是否为零

---

您无法从视图控制器创建导航控制器（有关说明，请参阅），您可以找到有关如何使用UINavigationController的教程。

请尝试下面的代码如果适用，这就是我在tableView DidSelectRowatineXpath中声明对象/变量的方式。在函数顶部声明对象（视图）

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

 AudioViewController *audioviewcontroller = [[AudioViewController alloc] initWithNibName:@"AudioViewController" bundle:nil];
 DisplayViewController *displayviewcontroller = [[DisplayViewController alloc] initWithNibName:@"DisplayViewController" bundle:nil];
 LichtViewController *lichtviewcontroller = [[LichtViewController alloc] initWithNibName:@"LichtViewController" bundle:nil];
 ProjektorViewController *projektorviewcontroller = [[ProjektorViewController alloc] initWithNibName:@"ProjektorViewController" bundle:nil];

 if (indexPath.row==0) {
    NSLog(@"Index 0");
    [self.navController pushViewController:audioviewcontroller animated:YES];
    [audioviewcontroller release];
    [tableView deselectRowAtIndexPath: indexPath animated:YES];
 }
 if (indexPath.row==1) {
    NSLog(@"Index 1");
    [self.navController pushViewController:displayviewcontroller animated:YES];
    [displayviewcontroller release];
    [tableView deselectRowAtIndexPath: indexPath animated:YES];
 }
 if (indexPath.row==2) {
    [self.navController pushViewController:lichtViewController animated:YES];
    [lichtviewcontroller release];
    [tableView deselectRowAtIndexPath: indexPath animated:YES];
    NSLog(@"Index 2");
 }
 if (indexPath.row==3) {
    NSLog(@"Index 3");
    [self.navController pushViewController:projektorviewcontroller animated:YES];
    [tableView deselectRowAtIndexPath: indexPath animated:YES];
    [projektorviewcontroller release];

 }
}

根据您的错误控制台，我认为问题在于节数。如果您提供完整的tableview代码，我认为问题会被发现。

我现在就去检查它。谢谢，我是headerfile中的navigationController。navigationController需要什么样的值？我测试了它，但效果是一样的。细胞会发光或熄灭，但没有任何作用。你试过从self.navController切换到self.navionController吗？非常感谢，那是我的错。UiViewController有一个属性navigationController，但我自己创建了一个navController，这导致了我的问题：）
