Question

我希望在iOS中更改取消按钮的标题。我之前一直在使用它：

- (void)searchDisplayControllerWillBeginSearch:(UISearchDisplayController *)controller{
  self.searchDisplayController.searchBar.showsCancelButton = YES;
  UIButton *cancelButton = nil;
  for (UIView *subView in self.searchDisplayController.searchBar.subviews) {
     if ([subView isKindOfClass:NSClassFromString(@"UIButton")]) {
         cancelButton = (UIButton*)subView;
     }
  }
  [cancelButton setTitle:@"Annuller" forState:UIControlStateNormal];
}

但它似乎无法在iOS7中运行。有什么建议？

Answer 1

您需要递归搜索按钮。这应该是一种自动防故障方式：

- (void)viewDidLoad
{
    [super viewDidLoad];

    [self convertButtonTitle:@"Cancel" toTitle:@"Annuller" inView:self.searchBar];
}

- (void)convertButtonTitle:(NSString *)from toTitle:(NSString *)to inView:(UIView *)view
{
    if ([view isKindOfClass:[UIButton class]])
    {
        UIButton *button = (UIButton *)view;
        if ([[button titleForState:UIControlStateNormal] isEqualToString:from])
        {
            [button setTitle:to forState:UIControlStateNormal];
        }
    }

    for (UIView *subview in view.subviews)
    {
        [self convertButtonTitle:from toTitle:to inView:subview];
    }
}

我仅在iOS 7上对此进行了测试，但它也适用于iOS 6。

Answer 2

只需为此代码执行： -

- (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar
{
    /* when user start editing in serchbar this method will display cancel button and disable the autocorrection functionality */

    srcbar.showsCancelButton = YES;

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

            [cancelButton setTitle:@"hi" forState:UIControlStateNormal];
        }
    }
    srcbar.autocorrectionType = UITextAutocorrectionTypeNo;

}

不在iOS7中测试，但在iOS6中这种工作正常，希望这对您有用。

输出为： -

Answer 3

这是我对ios6和i的解决方案ios7

#define IS_IOS7 (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1)
- (void)searchDisplayControllerWillBeginSearch:(UISearchDisplayController *)controller
{
    self.searchDisplayController.searchBar.showsCancelButton = YES;

    UISearchBar *searchBar = self.searchDisplayController.searchBar;
    UIView *viewTop = IS_IOS7 ? searchBar.subviews[0] : searchBar;
    NSString *classString = IS_IOS7 ? @"UINavigationButton" : @"UIButton";

    for (UIView *subView in viewTop.subviews) {
        if ([subView isKindOfClass:NSClassFromString(classString)]) {
            UIButton *cancelButton = (UIButton*)subView;
            [cancelButton setTitle:@"your title" forState:UIControlStateNormal];
        }
    }
}

Answer 4

为了使其在iOS7上运行，您必须在搜索栏的子视图中搜索：

//iOS 7 hack
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:@"Anuluj" forState:UIControlStateNormal];
    }
}

Answer 5

适用于Swift 3.0

这很好。

func setSearchButtonText(text:String,searchBar:UISearchBar) {

    for subview in searchBar.subviews {
        for innerSubViews in subview.subviews {
            if let cancelButton = innerSubViews as? UIButton {
                cancelButton.setTitleColor(UIColor.white, for: .normal)
                cancelButton.setTitle(text, for: .normal)
            }
        }
    }

}

并调用方法

setSearchButtonText(text: "Done", searchBar: yourSearchBar)

这是输出

Answer 6

将此行放在appDelegate
中

[[UIButton appearanceWhenContainedIn：[UISearchBar class]，nil] setTitle：@“Your Title”forState：UIControlStateNormal];

Answer 7

@Nitin Gohel是这样吗？

- (void)searchDisplayControllerWillBeginSearch:(UISearchDisplayController *)controller{
  self.searchDisplayController.searchBar.showsCancelButton = YES;
  UIButton *cancelButton = nil;
  for (UIView *subView in self.searchDisplayController.searchBar.subviews) {
     if ([subView isKindOfClass:NSClassFromString(@"UIButton")]) {
         cancelButton = (UIButton*)subView;

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

}

Answer 8

似乎“self.searchDisplayController.searchBar.subviews”只返回“searchBar”本身。我试着吼一声，它有效！

for (UIView *searBarView in [self.searchDisplayController.searchBar subviews])
{
    for (UIView *subView in [searBarView subviews]) 
    {
        if ([subView isKindOfClass:[UIButton class]])
        {
            UIButton *cancleButton = (UIButton *)subView;
            [cancleButton setTitle:@"hi" forState:UIControlStateNormal];
        }
    }

}

Answer 9

在搜索开始之前，在UISearchBarDelagate或UISearchDisplayControllerDelegate中执行：

[self.searchDisplayController.searchBar.subviews enumerateObjectsUsingBlock:^(UIButton *subview, NSUInteger idx, BOOL *stop) {
            if ([subview isKindOfClass:[UIButton class]]) {
                [subview setTitle:@"OK" forState:UIControlStateNormal];
                *stop = YES;
            }
        }];

Answer 10

如果您只想将“取消”文本更改为您的语言环境中的相同，我认为正确的方法是使用本地化。方法如下：

在Finder中打开您的项目，找到en.lproj目录
将其重命名为您的语言区域，如果您必须支持多种语言，则将其复制
删除Xcode中可能包含的任何文件引用（它们应该看起来是红色的）
将Finder中的相同文件从新目录拖到Xcode
（不确定是否有必要）编辑Info.plist并添加以下行：
- Localization native development region：您所在的地区（例如：en）
- Localizations：例如English

注意：它在Simulator中不起作用，在设备上进行测试！

Answer 11

对于iOS7，这可行。

-(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:@"YourTitle" forState:UIControlStateNormal];
    }
}

Answer 12

参考上面的@ Salih解决方案，我使用了这段代码并且完美无缺！只需在app启动时调用AppDelegate.m中的方法setupAppearance即可。

- (void)setupAppearance
{
   id appearance = nil;

   if (IOS9_OR_LATER) {
       appearance = [UIBarButtonItem appearanceWhenContainedInInstancesOfClasses:@[[UISearchBar class]]];
   } else {
       appearance = [UIBarButtonItem appearanceWhenContainedIn:[UISearchBar class], nil];
   }

   [appearance setTitle:@"CANCEL"];
}

Answer 13

使用UIKitUISearchResultsUpdating协议方法updateSearchResults(for searchController: UISearchController)中使用的代码进行访问：

if let cancelButton : UIButton = searchController.searchBar.value(forKey: "_cancelButton") as? UIButton {
    cancelButton.setTitle("Back", for: UIControlState.normal)
}
