我有一个表视图和UIView.Table View Cell在选择Perticuler小区时，可以使用映像的小区。在UIView中应该在“UIImage对象”中出现相应的图像。

在表视图类中：

//I'm getting temp image as following(in my "cellForRowAtIndexPath" method)
  if(indexPath.row == 0)
    {
        [[cell imageView]setImage:[UIImage imageNamed:@"greekChickenSalad.png"]];
        tempImage = [UIImage imageNamed:@"greekChickenSalad.png"];
    }

 -(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([segue.identifier isEqualToString:@"SubRecipeDescriptionSegue"])
{
     RecipeDescriptionViewController *rdVC;
    rdVC = segue.destinationViewController;
    rdVC.parentIndexRDVC = descriptionIndexPath;
    rdVC.DescriptionLabel = (UILabel*)subRecipeSelected;
    rdVC.image = tempImage;

}

}

在 UIView 中，LoadView 方法添加图像如下：

NSData *imageDataString = UIImagePNGRepresentation(image);
NSString *imageNamedContent = [[NSString alloc]initWithBytes:[imageDataString bytes] length:[imageDataString length] encoding:NSASCIIStringEncoding];
UIImage *image1 = [UIImage imageNamed:imageNamedContent];
UIImageView *imageView = [[UIImageView alloc]initWithImage:image1];
imageView.frame = CGRectMake(30,30, 250, 100);
[self.view addSubview:imageView];

在上面的代码中，我将图像转换为 NSString([UIImage imageNamed:imageNamedContent]) - 这是正确的吗？

如果没有，我该怎么做？

注意：如果我将表格单元格的文本传递给 UIView 中的标签，Segue 工作正常。

希望我的问题很清楚。

改变：

NSData *imageDataString = UIImagePNGRepresentation(image);
NSString *imageNamedContent = [[NSString alloc]initWithBytes:[imageDataString bytes] length:[imageDataString length] encoding:NSASCIIStringEncoding];
UIImage *image1 = [UIImage imageNamed:imageNamedContent];
UIImageView *imageView = [[UIImageView alloc]initWithImage:image1];

进入：

UIImageView *imageView = [[UIImageView alloc]initWithImage:image];

您还需要获取当前单元格的图像并将其与 performSegueWithIdentifier 一起发送：

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
    [self performSegueWithIdentifier:@"SubRecipeDescriptionSegue" sender:cell.imageView.image];
}

然后你需要更新你的 prepareForSegue 方法：

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([segue.identifier isEqualToString:@"SubRecipeDescriptionSegue"])
    {
        UIImage *selectedImage = (UIImage*)sender;

        RecipeDescriptionViewController *rdVC;
        rdVC = segue.destinationViewController;
        rdVC.parentIndexRDVC = descriptionIndexPath;
        rdVC.DescriptionLabel = (UILabel*)subRecipeSelected;
        rdVC.image = selectedImage;
    }
}
