如何更改UISearchBar+iPhone中出现的“取消”按钮的默认文本

在执行此过程之前,还需要使用“searchBar setShowsCancelButton”。

- (void)searchDisplayControllerWillBeginSearch:(UISearchDisplayController *)controller
{
    [theSearchBar setShowsCancelButton:YES animated:NO];
    for (UIView *subView in theSearchBar.subviews){
        if([subView isKindOfClass:[UIButton class]]){
            [(UIButton*)subView setTitle:@"Done" forState:UIControlStateNormal];
        }
    }
}

注意:使用UIButton避免苹果出现问题!

使用外观代理:

id barButtonAppearanceInSearchBar = [UIBarButtonItem appearanceWhenContainedIn:[UISearchBar class], nil];

[barButtonAppearanceInSearchBar setBackgroundImage:grayBackgroundImage forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
[barButtonAppearanceInSearchBar setTitleTextAttributes:@{
                                      NSFontAttributeName : [UIFont fontWithName:@"HelveticaNeue-CondensedBold" size:20],
                                 NSForegroundColorAttributeName : [UIColor blackColor]
     } forState:UIControlStateNormal];
[barButtonAppearanceInSearchBar setTitle:@"X"];

Mr. Jesper Nielsen -他写了密码。

-(void)searchDisplayControllerDidBeginSearch:(UISearchDisplayController *)controller {
    UIButton *cancelButton;
    UIView *topView = theSearchBar.subviews[0];
    for (UIView *subView in topView.subviews) {
        if ([subView isKindOfClass:NSClassFromString(@"UINavigationButton")]) {
            cancelButton = (UIButton*)subView;
        }
    }
    if (cancelButton) {
        [cancelButton setTitle:@"YourTitle" forState:UIControlStateNormal];
    }

}

如果“Search String”是指占位符,那么应该这样做:

[searchBar setPlaceholder:@"Whatever you want"];

for(UIView *view in [searchBar subviews]) {
    if([view isKindOfClass:[NSClassFromString(@"UINavigationButton") class]]) {
        [(UIBarItem *)view setTitle:@"Whatever you want"];
    }
}

请注意,cancel按钮是延迟加载的,因此您必须在用户激活搜索栏时进行此修改。

在ios7中,如果您使用UISearchBar,只需在searchBarTextDidBeginEditing:method中编写以下代码

searchBar.showsCancelButton = YES;UIView* view=searchBar.subviews[0];
for (UIView *subView in view.subviews) {
      if ([subView isKindOfClass:[UIButton class]]) {
          UIButton *cancelButton = (UIButton*)subView;

          [cancelButton setTitle:@"إلغاء" forState:UIControlStateNormal];
       }
}

我想修复UIAppearance技术,因为yar1vn代码不能与xcode5一起工作。

首先,您需要了解cancel按钮是一个私有的UINavigationButton:UIButton。因此,它不是一个uibarbuttonite。经过一些检查后,UINavigationButton似乎会响应那些UIAppearance选择器:

// inherited from UINavigationButton
@selector(setTintColor:)
@selector(setBackgroundImage:forState:style:barMetrics:)
@selector(setBackgroundImage:forState:barMetrics:)
@selector(setTitleTextAttributes:forState:)
@selector(setBackgroundVerticalPositionAdjustment:forBarMetrics:)
@selector(setTitlePositionAdjustment:forBarMetrics:)
@selector(setBackButtonBackgroundImage:forState:barMetrics:)
@selector(setBackButtonTitlePositionAdjustment:forBarMetrics:)
@selector(setBackButtonBackgroundVerticalPositionAdjustment:forBarMetrics:)

// inherited from UIButton
@selector(setTitle:forState:)

/* dual appearance technique by Cœur to customize a UINavigationButton */
Class barClass = [UISearchBar self];

UIBarButtonItem<UIAppearance> *barButtonItemAppearanceInBar = [UIBarButtonItem appearanceWhenContainedIn:barClass, nil];
[barButtonItemAppearanceInBar setTintColor:...];
[barButtonItemAppearanceInBar setBackgroundImage:... forState:... style:... barMetrics:...];
[barButtonItemAppearanceInBar setBackgroundImage:... forState:... barMetrics:...];
[barButtonItemAppearanceInBar setTitleTextAttributes:... forState:...];
[barButtonItemAppearanceInBar setBackgroundVerticalPositionAdjustment:... forBarMetrics:...];
[barButtonItemAppearanceInBar setTitlePositionAdjustment:... forBarMetrics:...];
[barButtonItemAppearanceInBar setBackButtonBackgroundImage:... forState:... barMetrics:...];
[barButtonItemAppearanceInBar setBackButtonTitlePositionAdjustment:... forBarMetrics:...];
[barButtonItemAppearanceInBar setBackButtonBackgroundVerticalPositionAdjustment:... forBarMetrics:...];

UIButton<UIAppearance> *buttonAppearanceInBar = [UIButton appearanceWhenContainedIn:barClass, nil];
[buttonAppearanceInBar setTitle:... forState:...];

[UINavigationBar self]

此解决方案适用于我-iOs7和iOs8:

@interface ... : ...
@property (strong, nonatomic) IBOutlet UISearchBar *search; 
@end

和

- (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar {
[searchBar setShowsCancelButton:YES animated:YES];

NSArray *searchBarSubViews = [[self.search.subviews objectAtIndex:0] subviews];
UIButton *cancelButton;
for (UIView *subView in searchBarSubViews) {
    if ([subView isKindOfClass:NSClassFromString(@"UINavigationButton")]) {
        cancelButton = (UIButton*)subView;
        break;
    }
}
if (cancelButton) {

    [cancelButton setTitle:@"New cancel" forState:UIControlStateNormal];

}
 //insert this two lines below if you have a button appearance like this "Ne...cel" 

[searchBar setShowsCancelButton:NO animated:YES];
[searchBar setShowsCancelButton:YES animated:YES]; 
}

在iOS 7上,如果您设置了 displaysSearchBarInNavigationBar = YES 在 UISearchDisplayController ,通过子视图递归或外观代理替换“取消”按钮标题 不起作用 .

相反,在中使用自己的工具栏按钮 viewDidLoad

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.searchDisplayController.displaysSearchBarInNavigationBar = YES;
    UIBarButtonItem *barItem = [[UIBarButtonItem alloc] initWithTitle:NSLocalizedString(@"A Custom Title", nil)
                                                                style:UIBarButtonItemStyleBordered
                                                               target:self
                                                               action:@selector(cancelButtonTapped:)];

    // NB: Order is important here.
    //     Only do this *after* setting displaysSearchBarInNavigationBar to YES
    //     as that's when UISearchDisplayController creates it's navigationItem
    self.searchDisplayController.navigationItem.rightBarButtonItem = barItem;
}

杰里米·特里普在斯威夫特的工作代码

func searchDisplayControllerWillBeginSearch(controller: UISearchDisplayController) {
    self.searchDisplayController?.searchBar.showsCancelButton = true
    var cancelButton: UIButton
    var topView: UIView = self.searchDisplayController?.searchBar.subviews[0] as UIView
    for subView in topView.subviews {
        if subView.isKindOfClass(NSClassFromString("UINavigationButton")) {
        cancelButton = subView as UIButton
        cancelButton.setTitle("My Custom Title", forState: UIControlState.Normal)
        }
    }
}

默认的“取消”标题为“取消”按钮,我更喜欢更改的值 循环流化床开发区 从en到项目中Info.plist文件中的本地化区域的键。

这是找我的钱,

<key>CFBundleDevelopmentRegion</key>
<string>zh_CN</string>

之后,默认的“取消”标题将显示为“中文”。此更改还将影响所有默认区域值,例如,UITextField/UITextView上粘贴板操作的操作标题将被本地化,“选择”->“,”粘贴“->”è"...

顺便说一下,Info.plist文件可以完全本地化。

我没有引用非公共的UINavigationButton类,而是执行了以下操作。我希望它能通过应用商店审查!

for (id subview in searchBar.subviews) {
    if ([subview respondsToSelector:@selector(setTitle:)]) {
        [subview setTitle:@"Map"];
    }
}

-(void)searchDisplayControllerWillBeginSearch:(UISearchDisplayController *)controller{
    self.searchDisplayController.searchBar.showsCancelButton = YES;
    UIButton *cancelButton;
    UIView *topView = self.searchDisplayController.searchBar.subviews[0];
    for (UIView *subView in topView.subviews) {
        if ([subView isKindOfClass:NSClassFromString(@"UINavigationButton")]) {
            cancelButton = (UIButton*)subView;
        }
    }
    if (cancelButton) {
      //Set the new title of the cancel button
        [cancelButton setTitle:@"Hi" forState:UIControlStateNormal];
    }
}

如果搜索栏在导航栏中,代码将与通常的答案不同;您需要搜索NavigationBar的子视图。

-(void)searchDisplayControllerDidBeginSearch:(UISearchDisplayController *)controller{
UINavigationBar * navigationBar =  self.navigationController.navigationBar;

for (UIView *subView in navigationBar.subviews){
    if([subView isKindOfClass:NSClassFromString(@"UINavigationButton")]){
        [(UIButton*)subView setTitle:@"Ä°ptal" forState:UIControlStateNormal];
    }
}}

在iOS7+中,如果你仍然不能设置标题,你应该学习视图调试-这就是我解决这个问题的方法。

这篇简短的教程很好地概述了调试的关键观点:

    if #available(iOS 13.0, *) {
        controller.searchBar.setValue("Done", forKey:"cancelButtonText")
    } else {
        controller.searchBar.setValue("Done", forKey:"_cancelButtonText")
    }

controller.searchBar.setValue("Done", forKey:"cancelButtonText") 适用于所有iOS版本

Swift 2.1中的工作短代码(已测试iOS7-9)

@IBOutlet weak var searchBar: UISearchBar!
func enableSearchBarCancelButton(enable: Bool, title: String? = nil) {
    searchBar?.showsCancelButton = enable
    if enable {
        if let _cancelButton = searchBar?.valueForKey("_cancelButton"),
            let cancelButton = _cancelButton as? UIButton {
                cancelButton.enabled = enable //comment out if you want this button disabled when keyboard is not visible
                if title != nil {
                    cancelButton.setTitle(title, forState: UIControlState.Normal)
                }
        }
    }
}
