将 UImage 传递给 UIImageView
我试图将从 UIImage 实例加载的图像传递到 DetailViewController 中的 UIImageView。我可以看到我正在成功拉取图像路径，并访问 .gif 文件，如 NSLogs () 中所示：
2011-02-09 10:52:13.404 WorldGovernments[31443:207] pathToMap = af-map.gif
2011-02-09 10:52:13.406 WorldGovernments[31443:207] detail map is: <UIImage: 0x4e44a80>
我不确定如何在以下方法中将此图像传递给 MapDetailsViewController ？
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
MapDetailsViewController *dvController = [[MapDetailsViewController alloc] initWithNibName:@"MapDetailsView" bundle:[NSBundle mainBundle]];
NSDictionary* tempDict=[sortedCountries objectAtIndex:indexPath.row];
NSString *pathToMap = [tempDict objectForKey:@"map"];
NSLog(@"pathToMap = %@",pathToMap);
UIImage *detailMap = [UIImage imageNamed:pathToMap];
NSLog(@"detail map is: %@",detailMap);
MapDetailsViewController.selectedImageView.image = detailMap;
[self.navigationController pushViewController:dvController animated:YES];
[dvController release];
//dvController = nil;
}
我知道我在这一行中做了一些可怕的错误：
MapDetailsViewController.selectedImageView.image = detailMap;
因为我在构建时收到此错误：
Request for member 'image' in something not a structure or union
I am trying to pass an image loaded from a UIImage instance to a UIImageView in a DetailViewController. I can see I am getting pulling he image path successfully, and accessing the .gif file as seen in my NSLogs () :
2011-02-09 10:52:13.404 WorldGovernments[31443:207] pathToMap = af-map.gif
2011-02-09 10:52:13.406 WorldGovernments[31443:207] detail map is: <UIImage: 0x4e44a80>
I am uncertain on how to pass this image to MapDetailsViewController in the following method?
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
MapDetailsViewController *dvController = [[MapDetailsViewController alloc] initWithNibName:@"MapDetailsView" bundle:[NSBundle mainBundle]];
NSDictionary* tempDict=[sortedCountries objectAtIndex:indexPath.row];
NSString *pathToMap = [tempDict objectForKey:@"map"];
NSLog(@"pathToMap = %@",pathToMap);
UIImage *detailMap = [UIImage imageNamed:pathToMap];
NSLog(@"detail map is: %@",detailMap);
MapDetailsViewController.selectedImageView.image = detailMap;
[self.navigationController pushViewController:dvController animated:YES];
[dvController release];
//dvController = nil;
}
I know I am doing something horribly wrong in this line :
MapDetailsViewController.selectedImageView.image = detailMap;
Since I get this error when I build:
Request for member 'image' in something not a structure or union

更改
将MapDetailsViewController.selectedImageView.image =DetailMap;
为
dvController.selectedImageView.image=detailMap;change
MapDetailsViewController.selectedImageView.image = detailMap;to
dvController.selectedImageView.image = detailMap;MapDetailsViewController.selectedImageView应该是dvController.selectedImageView.image = detailMap;。MapDetailsViewController.selectedImageViewshould bedvController.selectedImageView.image = detailMap;.
