Uitableview 在表视图中放置搜索栏。选择结果会给出错误的详细视图吗?
我已经创建了一个包含自定义单元格的TableView控制器,并使用MySQL数据库中的数据进行填充。一切都很好 我添加了一个搜索栏,搜索效果也很好。但是,当我选择搜索结果时,它会将我带到错误的详细视图(例如,我单击“Cookies”,它会将我发送到“Apples”的详细视图)。我的.m文件中缺少什么吗?这是我的密码: .mUitableview 在表视图中放置搜索栏。选择结果会给出错误的详细视图吗?,uitableview,uisearchdisplaycontroller,xcode4.6,Uitableview,Uisearchdisplaycontroller,Xcode4.6,我已经创建了一个包含自定义单元格的TableView控制器,并使用MySQL数据库中的数据进行填充。一切都很好 我添加了一个搜索栏,搜索效果也很好。但是,当我选择搜索结果时,它会将我带到错误的详细视图(例如,我单击“Cookies”,它会将我发送到“Apples”的详细视图)。我的.m文件中缺少什么吗?这是我的密码: .m - (int)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {

你好这将修复我的搜索栏结果,以显示正确的详细视图控制器。但是,当我实现此功能时,它会在我不搜索时从我的详细视图控制器中删除数据。例如,如果我只是从我的表视图中进行选择,它会推送到一个空的细节视图。空原因由[trains objectAtIndex:indexPath.row]返回空。我建议您不要使用两个UITableView(实例)。如果正在搜索,您可以更改UITableView的数据源并重新加载UITableView。我不知道这两个UITableView是如何显示的。“同一帧?”…如果正在搜索,您可以更改UITableView的数据源并重新加载UITableView。“我将如何执行此操作?”?我很困惑(这方面我还不太了解)。
