TTTableView隐藏返回TTTableViewController
问题描述:
我写的基于断Three20框架的应用程序,我似乎遇到了一些麻烦之后...TTTableView隐藏返回TTTableViewController
我使用TTTableViewController从端点加载数据和显示标题列表,可以单击它以呈现包含显示URL(从JSON数据获取)的UIWebView的新UIViewController。但是,当我点击UIViewController中的“返回”按钮时,视图弹出回来......但UIWebView不会消失(它是用[autorelease]定义的)。它停留在TTTableView应该在的位置之上。
我SearchResultViewController用于初始化一个UIWebView的代码是相当简单:
- (void)loadView {
....
// Add the UIWebView
webView = [[[UIWebView alloc] initWithFrame:CGRectMake(0.f, TT_ROW_HEIGHT + 20, TTApplicationFrame().size.width, TTApplicationFrame().size.height - TT_ROW_HEIGHT - toolbar.frame.size.height)] autorelease];
// Load the URL
address = self.productIdentifier;
NSURL *url = [NSURL URLWithString:address];
NSLog(@"%@",url);
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[webView loadRequest:requestObj];
[self.navigationController.view addSubview:webView];
....
}
而且SearchResultViewController推同样平凡:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@"Search Again" style:UIBarButtonItemStylePlain target:self action:@selector(goBack)];
self.navigationItem.backBarButtonItem = backButton;
[backButton release];
SearchResultViewController *srvc = [[SearchResultViewController alloc] init];
srvc.productIdentifier = [[[(id<SearchResultsModel>)self.model results] objectAtIndex:indexPath.row] url];
srvc.title = [[[(id<SearchResultsModel>)self.model results] objectAtIndex:indexPath.row] title];
srvc.hidesBottomBarWhenPushed = YES;
[self.navigationController pushViewController:srvc animated: YES];
}
答
想通了;可笑的愚蠢的错误。我将UIWebView添加到整个navigationController中,而不是我需要的视图中。Duh!
