- (void)viewDidLoad {
self.title = NSLocalizedString(@"Glossary", @"Back");

return 4;

}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
// Configure the cell...
NSUInteger row = [indexPath row];
if ( indexPath.section == 1 ) row += 7;
if ( indexPath.section == 2 ) row += 10;
if ( indexPath.section == 3 ) row += 16;
if ( indexPath.section == 4 ) row += 21;
cell.textLabel.text = [glossaryArray objectAtIndex:row];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
return cell;
}
Now this is the code I used to pussh a new view when a cell is tapped:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSInteger row = [indexPath row];
if (self.glossaryDetailViewController == nil) {
GlossaryDetailViewController *aGlossaryDetail = [[GlossaryDetailViewController alloc] initWithNibName:@"GlossaryDetailViewController" bundle:nil];
self.glossaryDetailViewController = aGlossaryDetail;
[aGlossaryDetail release];
}
glossaryDetailViewController.title = [NSString stringWithFormat:@"%@", [glossaryArray objectAtIndex:row]];
NewReferencemoi_caAppDelegate *delegate = (NewReferencemoi_caAppDelegate *)[[UIApplication sharedApplication] delegate];
[delegate.glossaryNavController pushViewController:glossaryDetailViewController animated:YES];
}
这段代码完美无缺,但问题是我的表视图中的每个和所有21个元素都打开了我创建的同一个nib文件。基本上,我想为我的21个元素中的每个元素创建1个UIViewController,其中每个元素都有自己的元素描述,而不仅仅是对我的表视图中的所有元素使用1个UIViewController,并且当每个元素被点击时,每个元素都打开它们自己的元素。视图。显然,我不知道如何在该部分编码,所以我希望有人可以帮助我解决我的iPhone项目的这一部分,谢谢
答案 0 :(得分:5)
请不要仅为了显示不同的项目而创建21个不同的视图控制器。而是在GlossaryDetailViewController
上设置一个包含数据模型项实例的属性。
考虑一下......
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSInteger row = [indexPath row];
if (self.glossaryDetailViewController == nil)
{
GlossaryDetailViewController *aGlossaryDetail = [[GlossaryDetailViewController alloc] initWithNibName:@"GlossaryDetailViewController" bundle:nil];
self.glossaryDetailViewController = aGlossaryDetail;
[aGlossaryDetail release];
}
glossaryDetailViewController.glossaryDetailItem = [glossaryArray objectAtIndex:row];
[self.navigationController pushViewController:self.glossaryDetailViewController animated:YES];
}
使用此方法会使GlossaryDetailViewController
负责设置自己的数据。

您还会注意到我删除了对应用程序委托的引用。您不需要它来访问导航控制器。导航控制器堆栈中的每个视图控制器都有对它的引用。当我彻底撕掉你的代码时,我也会通过覆盖glossaryDetailViewController
的getter来分解视图控制器的创建,如下所示:
- (GlossaryDetailViewController *)glossaryDetailViewController
{
if (!glossaryDetailViewController)
{
glossaryDetailViewController = [[GlossaryDetailViewController alloc] init];
}
return glossaryDetailViewController;
}
如果你走这条路,你可以删除if
语句,然后拨打self.glossaryDetailViewController
。
