我找到了自己问题的答案。

这是代码，AppDelegate如果要更改所有取消按钮，请添加。

[[UIBarButtonItem appearanceWhenContainedIn:[UISearchBar class], nil] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                                                                                  [UIColor redColor],
                                                                                                  UITextAttributeTextColor,
                                                                                                  [UIColor whiteColor],
                                                                                                  UITextAttributeTextShadowColor,
                                                                                                  [NSValue valueWithUIOffset:UIOffsetMake(0, 1)],
                                                                                                  UITextAttributeTextShadowOffset,
                                                                                                  nil]
                                                                                        forState:UIControlStateNormal];

迅速：

let attributes = [NSForegroundColorAttributeName : UIColor.red]
    UIBarButtonItem.appearance(whenContainedInInstancesOf: [UISearchBar.self]).setTitleTextAttributes(attributes, for: .normal)

更新为Swift 5：

let searchBarCancelButtonForegroundColor = UIColor.red
let attributes = [NSAttributedString.Key.foregroundColor: searchBarCancelButtonForegroundColor]

// Regular mode
UIBarButtonItem.appearance(whenContainedInInstancesOf: [UISearchBar.self]).setTitleTextAttributes(attributes, for: .normal)

// After click
UIBarButtonItem.appearance(whenContainedInInstancesOf: [UISearchBar.self]).tintColor = searchBarCancelButtonForegroundColor

为**工作SWIFT 4

使用模块的appearance功能UIAppearance-

方法1：-在加载时显示取消按钮searchBar-

let attributes = [NSAttributedStringKey.foregroundColor : UIColor.red]
    UIBarButtonItem.appearance(whenContainedInInstancesOf: [UISearchBar.self]).setTitleTextAttributes(attributes, for: .normal)

或者 -

方法 2： - 单击后显示取消按钮颜色searchBar-

  UIBarButtonItem.appearance(whenContainedInInstancesOf:[UISearchBar.self]).tintColor = UIColor.red

您可以更改UISearchBar类似这样的子视图- (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar

UIView *view = [_searchBar.subviews objectAtIndex:0];
for (UIView *subView in view.subviews) {
    if ([subView isKindOfClass:[UIButton class]]) {
        UIButton *cancelButton = (UIButton *)subView;
        [cancelButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
        [cancelButton setTitleColor:[UIColor whiteColor] forState:UIControlStateHighlighted];
    }
}

您可以按如下方式格式化您的搜索栏取消按钮

[[UIBarButtonItem appearanceWhenContainedIn: [UISearchBar class], nil] setTintColor:[UIColor whiteColor]];
    [[UIBarButtonItem appearanceWhenContainedIn: [UISearchBar class], nil] setTitle:@"Your Text Here"];

希望它对你有用。

斯威夫特 3：

使用此代码设置红色（文本、课程、按钮）

searchController.searchBar.tintColor = .red

如果您想将取消按钮颜色更改为白色，请添加此代码

UIBarButtonItem.appearance(whenContainedInInstancesOf: [UISearchBar.self]).setTitleTextAttributes([NSForegroundColorAttributeName : UIColor.white], for: .normal)

我独立设置光标和按钮颜色的方法是：我在 App Delegate 中将光标颜色设置为蓝色（-application:didFinishLaunchingWithOptions:)：

[[UITextField appearanceWhenContainedInInstancesOfClasses:@[[UISearchBar class]]] setTintColor:[UIColor blueColor]];

然后使用每个控制器中搜索栏的色调颜色来设置按钮颜色。您甚至可以在情节提要上设置色调颜色。

在 Swift 4 上测试

    let barButtonItem = UIBarButtonItem.appearance(whenContainedInInstancesOf: [UISearchBar.self])
    barButtonItem.title = NSLocalizedString("Cancel", comment: "")
    barButtonItem.setTitleTextAttributes([.font            : UIFont.systemFont(ofSize: 15.0, weight: .medium),
                                          .foregroundColor : #colorLiteral(red: 0.1960784314, green: 0.1960784314, blue: 0.1960784314, alpha: 1)], for: .normal)

UITextAttribute 已从 IOS 7 中弃用，适用于 IOS 7 或更高版本

[[UIBarButtonItem appearanceWhenContainedIn:[UISearchBar class], nil] setTitleTextAttributes:@{NSForegroundColorAttributeName : [UIColor whiteColor], NSFontAttributeName : [UIFont fontWithName:@"Helvetica" size:17]} forState:UIControlStateNormal];

UISearchBar 的替代方案是SHSearchBar。这个 swift 框架无需黑客攻击即可轻松定制，开源，有大量单元测试，可通过Cocoapods 获得。它至少需要 iOS 8。

对于使用 Swift 的人，我必须先添加 Eddie K 的扩展

然后我可以这样称呼它（基本上是 Sabo 在接受的答案中所做的）：
