我正在使用集合视图从我的服务器获取数据，在单元格中显示其中的一些数据，然后我对目标视图控制器有一个 segue 我得到了正确更新的图像，但由于某种原因，文本不会进入我的 UITextView

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

if ([segue.identifier isEqualToString:@"DetailSegue"]) {
    ICBCollectionViewCell *cell = (ICBCollectionViewCell *)sender;
    NSIndexPath *indexPath = [self.collectionView indexPathForCell:cell];
    ICBDetailViewController *dvc = (ICBDetailViewController *)[segue destinationViewController];

    path = [paths objectAtIndex:indexPath.row];
    Path = [path objectForKey:@"path"];
    title = [titles objectAtIndex:indexPath.row];
    Title = [title objectForKey:@"title"];
    sku = [SKUs objectAtIndex:indexPath.row];
    Sku = [sku objectForKey:@"SKU"];
    longDescrip = [longDescription objectAtIndex:indexPath.row];
    LongDescrip = [longDescrip objectForKey:@"longDescrip"];
    LongDescrip =@"Hello World";
    NSLog(@"Descrip =%@",LongDescrip);
    NSString *iconTitle =[NSString stringWithFormat:@"%@.png",Sku];
    NSString *docDir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
    NSString *fullPath = [docDir stringByAppendingPathComponent:[NSString stringWithFormat:@"/%@",iconTitle]]; //add our image to the path

    dvc.img = [[UIImage alloc] initWithContentsOfFile:fullPath];
    dvc.title = Title;
    //UITextView *descrip = (UITextView *)[cell viewWithTag:120];
    [dvc.descrip setText:@"Hello"];
}

}

我不确定它是否与发送到的对象是 UITextView 并且我正在向它发送 String 的事实有关

或者如果我有什么错误

这里也是 detailController 的 .m 和 .h

.h

#import <UIKit/UIKit.h>

   @interface ICBDetailViewController : UIViewController
   @property(weak) IBOutlet UIImageView *imageView;
   @property (strong) UIImage *img;
   @property(weak) IBOutlet UITextView *descrip;

@end

他们

#import "ICBDetailViewController.h"

    @interface ICBDetailViewController ()

@end

@implementation ICBDetailViewController

@synthesize imageView, img, descrip;

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

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

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

@end

希望有人能看到我两天错过的东西

在再次查看它之后，我注意到我错过了 .h 中的插座并忘记在 .m 的 ViewDidLoad 中设置它显示我也错过了将引用插座连接到我的 txtView
