没有故事板的表视图控制器的详细视图控制器? [英] Detail View Controller from Table View Controller WITHOUT Storyboard?
问题描述
我在控制器中有一个 tableview
,用于显示收据及其图像、创建日期等.
我这样做是为了当用户点击一个单元格时,它会转到 DetailViewController
.使用此代码:
I have a tableview
in a controller that shows receipts and their image, date created, etc.
I made it so when the user taps a cell, it goes to DetailViewController
. Using this code:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
ReceiptDetailViewController *controller = [[ReceiptDetailViewController alloc] initWithNibName:@"ReceiptDetailViewController" bundle:nil];
[self.navigationController pushViewController:controller animated:YES];
}
我想通过 UIImageView
、textView
等将图像、日期、类别等传递给我的新视图.
这是第一个控制器中我的表的代码:
I'd like to pass the image, date, category, etc, to my new view in a UIImageView
, textView
, etc.
This is the code for my Table in the first controller:
-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell"];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"Cell"];
}
cell.selectionStyle = UITableViewCellSelectionStyleGray;
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
Receipt *receipt = [self.receiptsArray objectAtIndex:indexPath.row];
ReceiptCategory *category = receipt.relationshipToCategory;
ReceiptImage *image = receipt.relationshipToImage;
cell.textLabel.text = category.receiptCategory;
cell.detailTextLabel.text = receipt.date.description;
if(self.imageCache.count <= indexPath.row) {
[self.imageCache addObject:[UIImage imageWithData:image.data]];
}
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 40, 40)];
imageView.image = [self.imageCache objectAtIndex:indexPath.row];
cell.imageView.image = imageView.image;
return cell;
}
我如何传递这些数据?我已经搜索了两天,所有解决方案都包含一个我没有使用的故事板.
How do I pass this data? I have searched around for two days now and all solutions include a storyboard, which I am not using.
推荐答案
您应该在 didSelectRowAtIndexPath: 中获得对您的收据的引用,并将其传递给 ReceiptDetailViewController.我假设你有属性来接受 ReceiptDetailViewController 中的数据:
You should get reference to your receipt in didSelectRowAtIndexPath: and pass it to ReceiptDetailViewController. I assume you have property to accept the data in ReceiptDetailViewController:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
//Get reference to receipt
Receipt *receipt = [self.receiptsArray objectAtIndex:indexPath.row];
ReceiptDetailViewController *controller = [[ReceiptDetailViewController alloc] initWithNibName:@"ReceiptDetailViewController" bundle:nil];
// Pass data to controller
controller.receipt = receipt;
[self.navigationController pushViewController:controller animated:YES];
}
在此示例中,您应该在 ReceiptDetailViewController.h 文件中创建属性:
It this example you should create property in ReceiptDetailViewController.h file:
@property(nonatomic, strong) Receipt *receipt;
现在您可以在您的 ReceiptDetailViewController 对象中使用它.
Now you can use it in your ReceiptDetailViewController object.
