在另一个viewcontroller中设置属性

您好，我试图在masterviewcontoller中设置一个属性，该属性属于另一个viewcontroller，但它不会进入set方法。我已经使用Masterviewcontroller到Detailviewcontroller做到了这一点，并且工作正常。现在，我复制该代码，并尝试使用masterviewcontroller将其复制到名为AddNoteViewController的控制器中。相同的代码，但不会进入set方法。我对两个类都具有相同的重要性，谢谢您的帮助！

在调试中有效

步骤1 masterviewController.m

//MasterViewController.m
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSDate *object = _objects[indexPath.row];
NSDate *kundnr = _kundnr[indexPath.row];
self.detailViewController.detailItem = object;
self.detailViewController.detailIdentity = kundnr;
self.addNoteViewController.AddNoteFtgnr = kundnr;

}

第二步DetailViewController.h

//DetailViewController.h
@property (strong, nonatomic) id detailItem;
@property (strong, nonatomic) id detailIdentity;

步骤3 DetailViewController.m

//DetailViewController.m
- (void)setDetailItem:(id)newDetailItem
{
if (_detailItem != newDetailItem) {
    _detailItem = newDetailItem;

    // Update the view.
    [self configureView];
}

if (self.masterPopoverController != nil) {
    [self.masterPopoverController dismissPopoverAnimated:YES];
}        
}

- (void)setDetailIdentity:(id)newDetailItentity
{
if (_detailIdentity != newDetailItentity) {
    _detailIdentity = newDetailItentity;

    // Update the view.
    [self configureView];
}

if (self.masterPopoverController != nil) {
    [self.masterPopoverController dismissPopoverAnimated:YES];
}
}

现在，AddNoteviewController不起作用

第1步masterviewController.m （我认为可以）

//MasterViewController.m
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSDate *object = _objects[indexPath.row];
NSDate *kundnr = _kundnr[indexPath.row];
self.detailViewController.detailItem = object;
self.detailViewController.detailIdentity = kundnr;
self.addNoteViewController.AddNoteFtgnr = kundnr;

}

第2步AddNoteViewController.h （我认为可以）

//AddNoteViewController.h
@interface AddNoteViewController : UIViewController

@property (strong, nonatomic) id AddNoteFtgnr;
@end

步骤3 AddNoteViewController.m （这是错误所在，根本不在这里介入）

//AddNoteViewController.m
-(void)setAddNoteFtgnr:(id)AddNoteFtgnr
{

//Code that sets the property

}
