我正在使用UItableView控制器，我无法将搜索栏添加到导航栏。我希望搜索栏来时，在导航栏上的搜索按钮被点击。如何在导航栏上添加搜索按钮和搜索栏。

在按钮单击=> .m文件时添加此文件：
UISearchBar *sBar = [[UISearchBar alloc]initWithFrame:CGRectMake(0,10,self.navigationController.navigationBar.bounds.size.width,self.navigationController.navigationBar.bounds.size.height/2)];
sBar.delegate = self;
[self.navigationController.navigationBar addSubview:sBar];并添加此=> .h文件

要制作这样的搜索栏，您需要在导航栏控制器中插入按钮，并将背景图像设置为search.png(您的图像)。因此，当用户单击此按钮时，set target as searchbar将打开。请检查以下代码以供参考。
首先，在你的.h文件中设置委托方法。
@interface FriendsViewController : UIViewController <UISearchDisplayDelegate,UISearchBarDelegate,UIAlertViewDelegate>
@property (nonatomic, strong) UIButton *searchButton;
@property (nonatomic, strong) UIBarButtonItem *searchItem;
@property (nonatomic, strong) UISearchBar *searchBar;
@property (strong, nonatomic) UISearchController *searchController;
@property (strong, nonatomic) UISearchDisplayController *d1;然后在你的nevigationbar中插入按钮。
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
UIButton *btn=[[UIButton alloc]initWithFrame:CGRectMake(279,9,25, 25)];
[btn setImage:[UIImage imageNamed:@"search"] //put here your searchimage
forState:UIControlStateNormal];
[btn setTitle:@"" forState:UIControlStateNormal];
[btn addTarget:self action:@selector(clickme:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *barbtn=[[UIBarButtonItem alloc]initWithCustomView:btn];
self.tabBarController.navigationItem.rightBarButtonItem=barbtn;
[self.tabBarController.navigationController.navigationBar setHidden:NO];现在你必须在你的clickme方法上设置搜索控制器。
- (IBAction)clickme:(id)sender{
UISearchBar *searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, 300, 44.0)];
searchBar.autoresizingMask =0;
searchBar.delegate = self;
searchBar.placeholder = @"Search for items...";
searchBar.showsScopeBar=YES;
UIView *searchBarWrapper = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 44)];
searchBarWrapper.autoresizingMask = 0;
[searchBarWrapper addSubview:searchBar];
self.searchItem = [[UIBarButtonItem alloc] initWithCustomView:searchBarWrapper];
self.tabBarController.navigationItem.leftBarButtonItem = self.searchItem;
self.navigationItem.rightBarButtonItem = nil;
self.navigationItem.titleView = nil;
////////////// ~ Search Display Controller as Object ~/////////////////////////////
self.d1 = [[UISearchDisplayController alloc] initWithSearchBar:searchBar contentsController:self];
self.d1.delegate = self;
self.d1.searchResultsDataSource = self;
self.d1.searchResultsDelegate = self;
self.d1.searchResultsTableView.rowHeight = 40;
self.d1.displaysSearchBarInNavigationBar = YES;
self.searchBar.translucent = NO;
self.searchBar.barTintColor = [UIColor grayColor];
self.d1.searchBar.tintColor = [UIColor blueColor];
[searchBar sizeToFit];
}

对于搜索按钮，如果需要，可以使用UIBarButtonSystemItemSearch。
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemSearch
target:self
action:@selector(actionSearch:)];你可以将搜索栏设置为导航栏的标题视图。
self.navigationItem.titleView = mySearchBar;页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
