遇到这个问题，虽然解决了，但接下来还是得好好找找问题的原因所在~~ 问题重现 未修改前的代码 self.tableView.tableHeaderView = self.searchController.searchBar...; 直接将searchBar设置为tableView的tableHeaderView，然后奇葩的现象就出现了，手动下拉刷新看不到刷新控件，待放手后才会出现，具体看图 ?...:CGRectMake(0, 0, KSCREEN_WIDTH, 45)]; [view addSubview:self.searchController.searchBar]; // 添加...searchbar 到 headerview self.tableView.tableHeaderView = view 方案二 -(UIView *)tableView:(UITableView *)...tableView viewForHeaderInSection:(NSInteger)section { return self.searchController.searchBar; }

iOS中UISearchBar(搜索框)使用总结 初始化：UISearchBar继承于UIView，我们可以像创建View那样创建searchBar UISearchBar * bar = [... [self.view addSubview:bar]; @property(nonatomic) UIBarStyle barStyle; 这个属性可以设置searchBar...void)searchBarTextDidEndEditing:(UISearchBar *)searchBar; 已经结束编辑的回调 - (void)searchBar...:(UISearchBar *)searchBar textDidChange:(NSString *)searchText; 编辑文字改变的回调 - (BOOL)searchBar:(UISearchBar...*)searchBar; 搜索结果按钮点击的回调 - (void)searchBar:(UISearchBar *)searchBar selectedScopeButtonIndexDidChange
=NO; _searchController.searchBar.barTintColor=[UIColor brownColor]; //设置searchbar的边框颜色和背景颜色一致..._searchController.searchBar.layer.borderWidth=1; _searchController.searchBar.layer.borderColor...= CGRectMake(self.searchController.searchBar.frame.origin.x, self.searchController.searchBar.frame.origin.y..., self.searchController.searchBar.frame.size.width, 44); _searchController.searchBar.delegate=self...怎么变中文呢，如下 -(BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar { [searchBar setShowsCancelButton
NO; //self.searchController.hidesNavigationBarDuringPresentation = NO; self.searchController.searchBar.frame...= CGRectMake(self.searchController.searchBar.frame.origin.x,self.searchController.searchBar.frame.origin.y...,self.searchController.searchBar.frame.size.width,44); self.tableView.tableHeaderView = self.searchController.searchBar...; self.searchController.searchBar.delegate = self; } 3 实现UISearchController的UISearchResultsUpdating...SearchResultVC *)navController.topViewController; [self filterContentForSearchText:self.searchController.searchBar.text
; //类型 //searchBar.barStyle = UIBarStyleBlack; //占位符 searchBar.placeholder = @"请输入搜索内容"; //副标题 //searchBar.prompt...; //显示按钮 searchBar.showsBookmarkButton = YES; searchBar.showsCancelButton = YES; searchBar.showsSearchResultsButton...= YES; searchBar.showsScopeBar = YES; [searchBar setScopeButtonTitles:[NSArray arrayWithObjects:@"a"..., @"b", @"c", @"d",nil]]; //设置代理 searchBar.delegate = self; - (void)searchBar:(UISearchBar *)searchBar...如果不为空，代表我们在搜索，tableView要显示搜索结果 if (searchBar.text == nil || [searchBar.text isEqualToString:@""]) {
searchController // 将搜索框视图�设置为tableView的tableHeaderView tableView.tableHeaderView = searchController.searchBar...添加searchBar 设置搜索框 // 搜索框 let bar = searchController.searchBar // 样式 bar.barStyle = .default // 设置光标及取消按钮的颜色...主要代码 上面仅作演示，下面的代码为searchBar的主要设置 let commonBgColor = RGBA(r: 0.94, g: 0.94, b: 0.96, a: 1.00) searchBar.barTintColor...= commonBgColor // 搜索框 searchBar.barStyle = .default searchBar.tintColor = RGBA(r: 0.12, g: 0.74, b...: .default) // 右侧语音 searchBar.showsBookmarkButton = true searchBar.setImage(#imageLiteral(resourceName
(Scale_X(20), Scale_Y(10), self.bounds.size.width-Scale_X(40), Scale_Y(36))]; searchBar.placeholder...= @"请输入搜索关键字"; searchBar.showsCancelButton = YES; searchBar.delegate =self;...searchBar.layer.cornerRadius=4; searchBar.clipsToBounds = YES; //不设置的话没有圆角 searchBar.delegate...= self; [searchBar setBackgroundImage:[UIImage imageNamed:@"sousuoBg"]]; [searchBar...]; #pragma mark - UISearchBarDelegate -(void)searchBar:(UISearchBar *)searchBar textDidChange
像素宽的黑色边框，去不掉 把 UISearchBar 放在 UITableView 头部的代码在 iOS 8 不起作用 tableView.tableHeaderView = searchController.searchBar...// now working 解决问题 1 searchController.searchBar.layer.borderWidth = 1 searchController.searchBar.layer.borderColor...= // your background color 解决问题 2 我发现 tableHeaderView 是可以被其他 view 有效填充的，不知道为什么 searchBar 就是放不进去，所以直接找个大小一样的...UIView 作为容器放在 searchBar 下面就好了。...64, view.frame.width, 44)) containerView.backgroundColor = // your background color searchController.searchBar.frame
FilterableProductTable (orange): 包含所有的子组件，是个容器 SearchBar (blue): 用于用户输入交互 ProductTable (green): 呈现数据项并根据用户输入过滤数据...至此，我们将这五个组件的继承关系确定下来： FilterableProductTable SearchBar ProductTable ProductCategoryRow ProductRow step2...在每一个状态期， 确保每个组件都会根据当前状态来渲染 寻找其共同的祖先组件 在继承链中层级较高的组件拥有state 回到我们的应用中， ProductTable需要根据state来过滤数据，SearchBar...我们需要给该组件设置getInitialState方法设置组件的初始状态，并且通过props将状态传递给ProductTable和SearchBar，最后我们就可以在ProductTable和SearchBar...所以我们通过在ProductTable和SearchBar设置事件监听函数，并且每当函数触发时setState当前的状态，促使组件渲染重绘，完成数据的动态呈现。
selector(segmentedControlClick:) forControlEvents:UIControlEventValueChanged]; self.searchController.searchBar.x...= 0; self.searchController.searchBar.y = 0; [headerView addSubview:self.searchController.searchBar];...= self; _searchController.dimsBackgroundDuringPresentation = NO; _searchController.searchBar.placeholder...= @"搜索"; [_searchController.searchBar sizeToFit]; } return _searchController; } 运行后发现搜索栏的位置偏移了...= @"搜索"; [_searchController.searchBar sizeToFit]; } return _searchController; } 到此搜索框就能正常是显示了
我们可以通过循环遍历出UISearchBar上所有展示出来的子视图 for(UIView*viewin[[[_searchController.searchBar subviews]lastObject...valueForKey:@"_background"]; UITextField*searchField = [_searchController.searchBar valueForKey:@"_...searchField"]; UIButton*cancelButton = [_searchController.searchBar valueForKey:@"_cancelButton"]; 当我们获取...cancelButton时，一定要确保cancelButton包含在了UISearchBar中，必要时可以提前调用： [_searchController.searchBar setShowsCancelButton...:YES animated:NO]; 去掉搜索框背景 for(UIView*viewin[[[_searchController.searchBar subviews]lastObject]subviews
数值 设置当前选中的标签 bindchange 函数 绑定选中的标签发生变化的回调事件 3.Searchbar...组件 Searchbar 组件，引用路径为： "weui-miniprogram/searchbar/searchbar" 示例代码： searchbar placeholder="查找朋友"...>searchbar> 下面展示了 Searchbar 组件的示例效果。
return cell;} UISearchBarDelegate中德 开始和结束的事件: - (BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar...{ NSLog(@"搜索Begin"); return YES; } - (BOOL)searchBarShouldEndEditing:(UISearchBar *)searchBar{ NSLog...(@"搜索End"}- (BOOL)searchBarShouldEndEditing:(UISearchBar *)searchBar{ NSLog(@"搜索End"); return YES;}...= CGRectMake(self.searchController.searchBar.frame.origin.x, self.searchController.searchBar.frame.origin.y..., self.searchController.searchBar.frame.size.width, 44.0); self.tableView.tableHeaderView = self.searchController.searchBar
实现搜索 我们是把searchBar抽出来放到了一个单独的类，我们可以把数据传进去，根据搜索的内容匹配搜索的结果在在searchPage展示，也可以把searcheBar的值告诉当前页面，之后进行搜索结果展示...2.1 searchBar搜索 class SearchBar extends StatefulWidget { final List?...searchResult; SearchBar({this.listData,this.searchResult}); @override _SearchBarState createState...onChanged; SearchBar({this.onChanged}); （滑动显示更多） 传递出去 if(widget.onChanged !...(text); } （滑动显示更多） 在page页接收 SearchBar(listData: widget.listData, searchResult:(List list
ion-searchbar的聚焦和失去焦点事件，看最新文档，是没有这两个关联事件的，如下截图所示： ?...ion-searchbar最新文档.png 然而，实际情况是，ionBlur和ionFocus确是能用的： searchbar (ionBlur)="checkBlur()" (ionFocus...)="checkFocus()"> searchbar> 什么原因？...ion-searchbar最新源码.png 或许有人会说，我记得以前可以的……没错，在3.1.0版本前，文档是有这两个事件说明的，只是后面版本都把它们移除掉了。
