我正在做主+详细信息页面。我已使用以下代码成功点击母版页中的单元格行跳转到详细信息页

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    [self performSegueWithIdentifier:@"MasterToDetail" sender:indexPath];
}

但是因为我的母版页单元格行也有辅助按钮，所以我需要通过点击使这些按钮也能够跳转到详细信息页面。所以我实现了代码

- (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath
{
    [self performSegueWithIdentifier:@"MasterToDetail" sender:self];
}

但是显示的详细信息不正确。它始终显示数据列表中的第一个详细数据。我将 sender:self 更改为 sender:indexPath 也不起作用。

我从这里和这里使用了 stackoverflow 的答案。我是初学者，所以有些概念还是不清楚对不起。

已编辑 - masterviewcontroller.m 的准备工作

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    DetailViewController *detailController =segue.destinationViewController;
    SearchDataDetail *bug = [self.bugs objectAtIndex:self.tableView.indexPathForSelectedRow.row];
    detailController.detailItem = bug;


}

-detailviewcontroller.m

#import "DetailViewController.h"
#import "SearchData.h"
#import "SearchDataDetail.h"

@interface DetailViewController ()
- (void)configureView;
@end

@implementation DetailViewController

- (void)configureView
{
    // Update the user interface for the detail item.
    self.rateView.notSelectedImage = [UIImage imageNamed:@"shockedface2_empty.png"];
    self.rateView.halfSelectedImage = [UIImage imageNamed:@"shockedface2_half.png"];
    self.rateView.fullSelectedImage = [UIImage imageNamed:@"shockedface2_full.png"];
    self.rateView.editable = YES;
    self.rateView.maxRating = 5;
    self.rateView.delegate = self;

    if (self.detailItem) {
        self.titleField.text = self.detailItem.data.title;
        self.rateView.rating = self.detailItem.data.rating;
        self.imageView.image = self.detailItem.fullImage;
    }

}


- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    [self configureView];
}

- (void)viewDidUnload
{
    [self setTitleField:nil];
    [self setRateView:nil];
    [self setImageView:nil];
    [super viewDidUnload];
    // Release any retained subviews of the main view.
    // e.g. self.myOutlet = nil;
}

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

{
    // Return YES for supported orientations
    return YES;
}

- (void)rateView:(RateView *)rateView ratingDidChange:(float)rating {
    self.detailItem.data.rating = rating;
}

这是由于以下声明

SearchDataDetail *bug = [self.bugs objectAtIndex:self.tableView.indexPathForSelectedRow.row];

这self.tableView.indexPathForSelectedRow.row仅适用于行选择，不适用于附件按钮点击。

你可以通过两种简单的方法解决它

  1. 在 .h 文件中声明一个变量来存储 indexPath 并使用它来传递选定的 indexPath。
  2. 在发件人中传递 indexPath

一切顺利..
