Question

我正在使用storyboard和Xcode 5.我是ios的新手。我怎样才能给同一个视图控制器两个功能用户也可以添加数据和编辑数据。我的导航栏中有条形按钮。 DispalyDataController 1：UITableView AddEditController 2：Textfields，标记简单的表单数据一旦AddEditController 2被填满，那么它必须显示在DispalyDataController 1上的tableview上

我正在使用以下代码

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{

  AddEditController *controllerAddEdit;
 controllerAddEdit.arraypassed = self.dataArray;

   }

Answer 1

您需要通过选择segue并移至属性检查器来设置标识符

  -(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
   if([[segue identifier] isEqualToString:@"Edit"] ){

  AddEditController *controllerAddEdit = segue.destinationViewController;
  controllerAddEdit.editModeOn = YES;
  controllerAddEdit.arraypassed = self.dataArray;

     }

    if([[segue identifier] isEqualToString:@"Add"] ){

    AddEditController *controllerAddEdit = segue.destinationViewController;
    controllerAddEdit.editModeOn = NO;

   }


  }

Answer 2

问题是你的视图控制器是零，你需要把它拉出segue ...试试这个......

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    AddEditController *controllerAddEdit = (AddEditController *)[segue destinationViewController];
    controllerAddEdit.arraypassed = self.dataArray;
}
