objective-c - tableview 根据点击的行打开不同的视图

Question

我目前正在创建一个带有 tableview 的应用程序，现在我喜欢发生的是，当我单击第一行时，它将显示 view1，当我单击第二行时，它将显示 view2。我怎样才能做到这一点？

我尝试使用 if else 语句 id my didSelectRowAtIndexPath但它在这里不起作用是我的一段代码

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

int EntryIndex = [indexPath indexAtPosition:[indexPath length]-1];

{
    AboutViewController *aboutView = [[AboutViewController alloc]init];
    aboutView.getId4 = [[contentArray objectAtIndex:EntryIndex]objectForKey:@"title"];
    aboutView.aboutofficeId = getId3;
     [self.navigationController pushViewController:aboutView animated:YES];
}
else
{
    DepartmentsViewController *deptView = [[DepartmentsViewController alloc]init];
    deptView.getId5 = [[contentArray objectAtIndex:EntryIndex]objectForKey:@"title"];
    deptView.deptoffice = getId3;
    [self.navigationController pushViewController:deptView animated:YES];
}

}

注意：你想创建和显示 UIView，所以我把UIViewNot 放在这里UIViewController。

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

        if(indexPath.row == 1)
        {
            UIView *view1 = [[UIView alloc] initWithFrame:CGRectMake("AsYouWnat")];
            view1.backgroundColor = [UIColor redColor];
            [self.view addSubview:view1];
        }
        else if(indexPath.row  == 2)
        {
            UIView *view2 = [[UIView alloc] initWithFrame:CGRectMake("AsYouWnat")];
            view2.backgroundColor = [UIColor redColor];
            [self.view addSubview:view2];
        }
        .
        .
        .
        .
        .
        ////////// As Your Row In Table
        else
        {
            UIView *viewN = [[UIView alloc] initWithFrame:CGRectMake("AsYouWnat")];
            viewN.backgroundColor = [UIColor redColor];
            [self.view addSubview:viewN];
        }
    }

1. 如果您希望显示视图，您可以声明一个 Mutable 数组并在其中添加 UIview，如果 UIview 内容具有不同类型的内容样式。

2. 如果您需要显示相同样式的视图，但只有内容不同。您可以查找以下代码。

   UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0,0,320,460)];
   switch (indexPath.row) {
   case 0:
   { 
   //Add your label,image,etc  
   [self.view addSubview:view];
   }
       break;
   
       case 1:
   {
   
   //Add your label,image,etc  
   [self.view addSubview:view];
   
   }
       break;
   

3. 如果要显示不同的 ViewController，则需要执行以下代码

   #import "ViewController1.h"
   #import "ViewController2.h"
   #import "ViewController3.h"
   
   -(void)viewDidLoad
   {
   
    VCArray=[[NSMutableArray alloc]initWithObjects:ViewController1,ViewController2,ViewController3];//allocate and init ViewController and add that to VCArray
   
    }
   
   
   
   - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
   {
   
    UIViewController *viewcontr=[VCArray objectAtIndex:indexpath.row];
    viewcontr=[[viewcontr alloc]init];
    [self presentModalViewController:viewcontr animated:YES];
   
     }
