Ios 将数据从动态tableview传递回静态tableview

请帮助我，我一直在努力传回数据。我有两个桌面视图。第一个表视图=静态表=RootVC。第二个表格视图=动态表格=第一个VC。在RootVC中，我有一个带有两个标签的单元格，“repeatLabel”和带有披露指示符的“repeatDetail”。当我点击该单元格时，它会显示下一个表FirstVC，FistVC将填充工作日。在选择了我的选择之后，我希望选择的日期以“repeatDetail”的形式传递回RootVC，并且当我返回时仍然能够看到以前选择的数据

我的RootVC如下所示：

    #import "RepeatViewController.h"
    @interface SettingsViewController : UITableViewController
    @property (strong, nonatomic) IBOutlet UILabel *repeatDetail;
    @property (strong, nonatomic) IBOutlet UILabel *repeatLabel;
    @property (strong,nonatomic) NSString *getRepeatDetail;
    @property (nonatomic, strong) NSMutableArray *selectedDaysArray;
    @end


    in my RootVC.m
    #import "SettingsViewController.h"

    @interface SettingsViewController ()

    @end

    @implementation SettingsViewController
    @synthesize repeatLabel,repeatDetail;
    @synthesize getRepeatLabel;
    @synthesize selectedDaysArray;
    - (void)viewDidLoad
    {
        [super viewDidLoad];
        repeatLabel.text = @"Repeat";
        repeatDetail.text = getRepeatLabel;



    }

    - (void)didReceiveMemoryWarning
    {
        [super didReceiveMemoryWarning];
        // Dispose of any resources that can be recreated.
    }



     - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
    {
        RepeatViewController *destinationController = segue.destinationViewController;
        if( [destinationController isKindOfClass:[RepeatViewController class]] )
        {
            //You can reuse your selectedDays arrays
            destinationController.selectedDays = self.selectedDaysArray;
            [(RepeatViewController *)destinationController setCompletionBlock:^(NSArray *retDaysArray) // <- make this change
             {


                 // Save your changes
                 self.selectedDaysArray = [NSMutableArray arrayWithArray: retDaysArray]; // <- make this change

                 NSLog(@"retDaysArray: %@", self.selectedDaysArray); //<- Add this debug line
             }];
        }
    }


    @end

//您可以重复使用selectedDays数组
destinationController.selectedDays=self.selectedDaysArray；
[（RepeatViewController*）destinationController setCompletionBlock:^（NSArray*retDaysArray）//当您使用静态单元格时，您必须直接绑定正在使用的控件，而无需绑定

因此，我可以向您提出以下建议：

使用特定标识符绑定控件，如LabelFieldDrow{rowid}示例：LabelFieldDrow1
因此，在准备segue时，只需检查所选行的内容，并将所需数据传递给目标控制器
可能不是最好的，但它应该可以工作。
您必须将数据（以前由用户选择）从您的RootVC传递到FirstVC。要在RootVC中执行此操作，请添加属性以保留所选数据

@property (nonatomic, strong) NSMutableArray *selectedDaysArray;

在prepareForSegue方法中，您必须传递该数组以让表视图知道需要选择什么：

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
    {
        UIViewController *destinationController = segue.destinationViewController;
        if( [destinationController isKindOfClass:[RepeatViewController class]] )
        {
            //You can reuse your selectedDays arrays
             ((RepeatViewController*)destinationController).selectedDays = self.selectedDaysArray;
            [(RepeatViewController *)destinationController setReturnBlock:^(NSArray *retDaysArray) // <- make this change
             {
                 // Save your changes
                 self.selectedDaysArray = [NSMutableArray arrayWithArray: retDaysArray]; // <- make this change
                 NSLog(@"DATA: %@", self.selectedDaysArray) //<- Add this debug line
             }];
        }
    }

在CellForRowinIndepath中，替换此行：

cell.textLabel.text = [completionBlock objectAtIndex:indexPath.row];

使用此代码：

    NSString *day = completionBlock[indexPath.row];
    cell.textLabel.text = day;
    if ([self.selectedDays containsObject:day])
        cell.accessoryType = UITableViewCellAccessoryCheckmark;
    else
        cell.accessoryType = UITableViewCellAccessoryNone;

并将didSelectRowAtIndexPath:更改为

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    if (!self.selectedDays)
        self.selectedDays = [[NSMutableArray alloc] init];
    if (cell.accessoryType == UITableViewCellAccessoryCheckmark)
    {
        cell.accessoryType = UITableViewCellAccessoryNone;
        //remove data from array
        [self.selectedDays removeObject:[completionBlock objectAtIndex:indexPath.row]];
    }
    else
    {
        cell.accessoryType = UITableViewCellAccessoryCheckmark;
        //add data to array
        [self.selectedDays addObject:[completionBlock objectAtIndex:indexPath.row]];
    }

    [tableView deselectRowAtIndexPath:indexPath animated:YES];
}

希望能有所帮助。
嗨，卡米洛，我是IOS新手，我如何才能做到这一点，最好的方法是什么？你知道如何将脚本中的控件绑定到你的控制器类吗？很抱歉，我问了一个问题，我该怎么做？我还是个新手，试图理解TableView。答案=不，我不知道怎么做。我发布了答案。让我知道答案是什么e、 嗨，格雷格，它仍然不工作。没有数据被传递到RootVC。我在帖子中添加了调试行。你能添加它并看到吗？你能在控制台中看到输出吗？选择有效吗（它还记得所选的日子吗）？不知道，我已经发布了我所拥有的。没有数据被传递到RootVC查看这一行[（RepeatViewController*）destinationController setReturnBlock:我将其从[（RepeatViewController*）更改为destinationController setCompletionBlock:。如果您还有任何问题，请告诉我。如果我有“UIViewController”，我会收到一个错误-在“UIViewController”类型的对象中找不到属性“selectedDays”
