iOS更改UISearchBar中取消按鈕的標題

Question

我希望在iOS中更改取消按鈕的標題。 我之前一直在用這個：

- (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];
}

但它似乎不適用於iOS7。 有什么建議？

Answer 1

您需要遞歸搜索按鈕。 這應該是一種自動防故障的方法：

- (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];
    }
}

我已經在iOS 7上測試了這個，但它也適用於iOS 6也應該這樣做。

Answer 2

只需為它執行此代碼： -

- (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;

}

不是在iOS7中測試，但在iOS6中這種工作正常，希望這對你有用。

Answer 3

這是我對ios6和ios7的解決方案

#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

為了使其在iOS7上運行，您必須在搜索欄的子視圖中搜索：

//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

對於Swift 3.0

這工作正常。

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)
            }
        }
    }

}

並調用該方法

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

這是輸出

Answer 6

把這一行放在appDelegate中

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

Answer 7

@Nitin Gohel喜歡這樣嗎？

- (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

看起來像“self.searchDisplayController.searchBar.subviews”只是返回“searchBar”本身。 我試着吼一聲，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

在搜索開始之前，在UISearchBarDelagate或UISearchDisplayControllerDelegate中執行：

[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

如果您只想將“取消”文本更改為您的語言環境中的相同，我認為正確的方法是使用本地化。 方法如下：

1. 在Finder中打開您的項目，找到en.lproj目錄
2. 將其重命名為您的語言環境，或者如果您必須支持多種語言則將其復制
3. 刪除它可能包含在Xcode中的任何文件引用（它們應該看起來是紅色的）
4. 將Finder中的相同文件從新目錄拖到Xcode

5. （不確定這是否必要）編輯Info.plist並添加以下行：

   • Localization native development region ：您的區域（例如： en ）
   • Localizations ：例如English

注意：它在Simulator中不起作用，在設備上測試！

Answer 11

對於iOS7，這是有效的。

-(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

請參考上面的@ Salih解決方案，我使用了這段代碼並且完美無缺！ 只需在app啟動時調用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

使用我在UIKitUISearchResultsUpdating協議方法中使用的代碼進行UIKitUISearchResultsUpdating updateSearchResults(for searchController: UISearchController) ：

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

（iOS 10，Swift 3.0）
