从UITableView导航到不同的ViewControllers

Question

我是IOS Objective C Programming的新手。我正在尝试一个非常简单的应用程序我的主页是标准的View Controller，我有一个简单的UITableView。我想要做的是当用户在表视图上选择不同的单元格时，使用不同的视图控制器。目前我填充了3条简单的线条。我搜索了许多历史讨论，但似乎无法工作（从segue选项到简单的实例化视图选项）。我简要介绍一下我的代码，希望有人能指出我在这里做错了什么。

Answer 1

按照您想要从tableview引用视图控制器的顺序创建一个包含segue名称的数组，然后在

中

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

你可以打电话

[self performSegueWithIdentifier:[array valueAtIndex:indexPath.row sender:nil];

Answer 2

如果是通过XIB：

Your_ViewController *vc = [[Your_ViewController alloc] initWithNibName:@"Your_ViewController" bundle:nil];
[self.navigationController pushViewController:vc animated:YES];

如果是通过StoryBoard：

UIStoryboard *storyBoard = [UIStoryboard storyboardWithName:@"Main_storyboard" bundle:[NSBundle mainBundle]];
Your_ViewController *vc = [storyBoard instantiateViewControllerWithIdentifier:@"storyboardID"];
[[self navigationController] pushViewController:vc animated:YES];

如果是通过编码：

Your_ViewController *vc = [[Your_ViewController alloc] initWithNibName:nil bundle:nil];
[self.navigationController pushViewController:vc animated:YES];

对于你的问题：

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
   // Put above code here according to your requirement....
}

Answer 3

试试这个

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    firstViewController *u = [[ContactDetailsVC alloc]init];
    u= [self.storyboard instantiateViewControllerWithIdentifier:@"firstView"];
    [self.navigationController pushViewController:u animated:YES];
}

确保您使用NavigationController或Not进行嵌入，如果不是，

只需按以下方式执行

在这里，我们可以使用两种类型导航

• 通过连接
• 少连接

通过连接

 - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
   NSString *SegName = @"";
   if (indexPath.row == 0)
   {
     SegName = @"firstSegumeName";
   }
   else if (indexPath.row == 1)
   {
    SegName = @"secondSegumeName";
   }
  else  if (indexPath.row == 2)
   {
     SegName = @"thirdSegumeName";
   }
    [self performSegueWithIdentifier:SegName sender:self];

}

少连接

 if use `storyboard ID` with connection less

例如

  - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
        UIViewController *otherViewCon;
        if (indexPath.row == 0)
   {
      otherViewCon = [self.storyboard instantiateViewControllerWithIdentifier:@"yourfirstIdentifierName"];
   }
   else if (indexPath.row == 1)
   {
     otherViewCon = [self.storyboard instantiateViewControllerWithIdentifier:@"yoursecondIdentifierName"];
   }
  else  if (indexPath.row == 2)
   {
      otherViewCon = [self.storyboard instantiateViewControllerWithIdentifier:@"yourthirdIdentifierName"];
   }


        [self.navigationController pushViewController:otherViewCon animated:YES];
    }

Answer 5

将didSelectRowAtIndexPath的最后2行替换为：

UINavigationController *navC = [[UINavigationController alloc] initWithRootViewController:myView];
[self presentViewController:navC animated:YES completion:nil];
