Ios UISearchBar:隐藏在搜索栏后面的搜索结果
我实现了一个空的ViewController,即带有搜索栏的SearchViewController。Ans当我从web服务搜索时,我希望搜索结果仅在用户按下搜索按钮时显示。这已得到实施。问题是,结果以一种奇怪的方式出现,如下所示: 不知道他们隐藏了什么。我怎样才能把它们带到最前面 这是我的密码:Ios UISearchBar:隐藏在搜索栏后面的搜索结果,ios,swift,uisearchbar,uisearchdisplaycontroller,Ios,Swift,Uisearchbar,Uisearchdisplaycontroller,我实现了一个空的ViewController,即带有搜索栏的SearchViewController。Ans当我从web服务搜索时,我希望搜索结果仅在用户按下搜索按钮时显示。这已得到实施。问题是,结果以一种奇怪的方式出现,如下所示: 不知道他们隐藏了什么。我怎样才能把它们带到最前面 这是我的密码: override func viewDidLoad() { super.viewDidLoad() self.api.delegate = self activateSea

我可能会做些傻事。’我想不出是什么。。请帮助看起来您的搜索栏已放置在您的表视图上方。尝试在情节提要中缩小表格视图的比例,使表格视图的顶部位于搜索栏元素的下方。结果应正确显示如果您在ViewWillDisplay方法中更改searchTableView框架,则当您在同一视图控制器中时,该方法将不会被调用 尝试在searchBarSearchButtonClicked方法内更改searchTableView框架 希望这能解决您的问题。:) 编辑: 还可以尝试将搜索栏添加到searchTableView标题
self.searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 320.0f, 44.0f)] ;
self.searchBar.autocorrectionType = UITextAutocorrectionTypeNo;
self.searchBar.autocapitalizationType = UITextAutocapitalizationTypeNone;
self.searchBar.keyboardType = UIKeyboardTypeAlphabet;
self.searchBar.delegate = self;
self.tableView.tableHeaderView = self.searchBar;
下面是用于将搜索栏添加到tableView标题的objective-c代码
self.searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 320.0f, 44.0f)] ;
self.searchBar.autocorrectionType = UITextAutocorrectionTypeNo;
self.searchBar.autocapitalizationType = UITextAutocapitalizationTypeNone;
self.searchBar.keyboardType = UIKeyboardTypeAlphabet;
self.searchBar.delegate = self;
self.tableView.tableHeaderView = self.searchBar;
如果有人遇到像我这样的情况,就把答案贴出来 我没有将

为什么要将其标记为-1??4.我真的被卡住了,只好求助。。我删除了viewWillAppear方法..bt仍然无效:(如sharvan所示,将搜索栏视图添加为tableview标题的自定义标题视图问题可以在泰国bcz解决,搜索栏显示在表格标题中,表格标题始终位于结果表格的顶部。尝试将搜索栏放置在所有可能的位置。没有任何帮助:(
