Question

当我选择某个单元格时，它不会显示DetailViewController 那是来自DetailViewController.h的鳕鱼

#import <UIKit/UIKit.h>
@interface DetailViewController : UIViewController
@property(nonatomic,strong) NSString *imageName;
@property(nonatomic,strong) IBOutlet UIImageView *imageView;
@end

来自DetailViewController.m的Cod

#import "DetailViewController.h"

@interface DetailViewController ()

@end

@implementation DetailViewController
@synthesize imageName,imageView;

- (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 from its nib.
    imageView.image=[UIImage imageNamed:imageName];
}

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

@end

和ViewController.m` #import“ViewController.h” #import“DetailViewController.h”

@interface ViewController (){
    NSArray *soundtitles;
    NSArray *thumbs;
}

@end

@implementation ViewController
@synthesize tableView;
- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
  //  self.title=@"Точки";
soundtitles = [[NSArray alloc]initWithObjects:@"novaposhta",@"ac-2",@"vugovskogo",@"naykova ",@"iskra",nil];
    thumbs=[[NSArray alloc]initWithObjects:@"thumbsnovaposhta.jpg",@"thumbsac-2.jpg",@"thumbvugovskogo.jpg",@"thumbnaykova.jpg",@"thumbsiskra.jpg", nil];
    tableView.backgroundColor=[UIColor clearColor];
    tableView.alpha=0.9;
}

                                        }

  cell.textLabel.text=[soundtitles objectAtIndex:indexPath.row];
    cell.imageView.image=[UIImage imageNamed:[thumbs objectAtIndex:indexPath.row]];

      detailScreen.imageName=selectedImage;
      [self.navigationController pushViewController:detailScreen animated:YES];

  }

    - (void)didReceiveMemoryWarning

我还添加了NavigatorController，但它没有帮助。

Answer 1

如果你正确地复制了代码：

 -(void)tableView:(UITableView*)tableViewdidSelectRowAtIndexPath:(NSIndexPath*)indexPath

tableView和didSelectRowAtIndexPath

之间必须有空格

Answer 2

更正方法如下：

- （void）tableView：（UITableView *）tableView didSelectRowAtIndexPath：（NSIndexPath *）indexPath { //你的代码}

而不是你的方法

- （无效）的tableView：（UITableView的*）tableViewdidSelectRowAtIndexPath：（NSIndexPath *）indexPath

你忘记添加空格检查两种方法
