如何从Masterview推动到故事板的详细视图？

Question

我试图推动故事板中的详细视图，但不工作。

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender 
{ 
    if ([[segue identifier] isEqualToString:@"drinkList"]) 
    { 
     NSIndexPath *myIndexPath = [self.drinksCatTable indexPathForSelectedRow]; 

     if (myIndexPath.row ==0) //if selected is row 1 
     { 
      selectedDrinkCat =[segue destinationViewController]; 
      Drinks *drinkList = [aDelegate.categoryArray objectAtIndex:0];//forward all drinks to drinksList 
      selectedDrinkCat.drinkList = drinkList;//point drinkList to the next view drinkList 
      selectedDrinkCat.allDrinkStr = @"All";//all drinks selected 
       NSLog(@"aaa"); 
     } 
     else 
     { 
      Drinks *drinkList = [aDelegate.categoryArray objectAtIndex:(myIndexPath.row)-1];//we have to minus 1 as the row had en extra "All" row which is not in the database 
      selectedDrinkCat.drinkList = drinkList; 
      selectedDrinkCat.allDrinkStr [email protected]"cat"; 
      NSLog(@"1111"); 

     } 
    } 
} 

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

    [self performSegueWithIdentifier:@"drinkList" sender:self]; 
    NSLog(@"called did select"); 

} 

Answer 1

您不应该将selectedDrinkCat声明为destinationViewController类的viewcontroller吗？

喜欢的东西：

desmondViewController *selectedDrinkCat=(desmondViewController *)[segue destinationViewController]; 

Answer 2

您必须使用视图控制器的pushViewController:方法。

Answer 3

执行以下操作：

• 转到storyboard文件
• 点击viewcontroller1然后按主视图 - 控制（鼠标+ ^），并从上下文菜单拖到viewController2
• 选择推
• 将在这些视图之间创建链接，点击它并在检查员更改Indetifier至drinkList

这设置了故事板

现在您编写的代码应该可以工作。
