我该如何改变？

Answer 1

我找到了自己问题的答案。

以下是代码，如果要更改所有取消按钮，请添加AppDelegate。

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

夫特：

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

Answer 2

如果您只想设置按钮的文字颜色，则只需要一行：

[[UIBarButtonItem appearanceWhenContainedIn: [UISearchBar class], nil] setTintColor:[UIColor redColor]];

Answer 3

你可以这样做

[yourSearchBarName setTintColor:[UIColor whateverColorYouWant]];

Answer 4

更简单的方法 - ＆gt;

awk -F '[- ]' '!seen[$6]++ {n++} END {print n}' file

Answer 5

您可以在UISearchBar

中更改- (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar的子视图

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];
    }
}

Answer 6

您可以按如下方式格式化搜索栏取消按钮

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

希望它适合你。

Answer 7

已更新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

适用于SWIFT 4

使用appearance模块的UIAppearance功能 -

方法1： - 使用searchBar加载时显示取消按钮 -

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

或 -

方法2： - 单击searchBar后显示取消按钮颜色 -

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

Answer 8

斯威夫特3：

使用此代码设置红色（文字， courser，button）

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)

Answer 9

[[UISearchBar appearance] setTintColor:[UIColor redColor]];

Answer 10

快速4.2

let attributes = [NSAttributedString.Key.foregroundColor: UIColor.white]
UIBarButtonItem.appearance(whenContainedInInstancesOf: [UISearchBar.self]).setTitleTextAttributes(attributes, for: UIControl.State.normal)

Answer 11

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)

Answer 12

对于Swift 3：

self.searchController.searchBar.tintColor = UIColor.white

Answer 13

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

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

然后在每个控制器中使用搜索栏的色调颜色来设置按钮颜色。您甚至可以在故事板上设置色调颜色。

Answer 14

UISearchBar的替代方案是SHSearchBar。这个快速框架很容易定制，没有黑客攻击，开源，有很多单元测试，可以通过Cocoapods获得。它至少需要iOS 8。

Answer 15

Swift 4

let uiButton = bar.value(forKey: "cancelButton") as? UIButton
uiButton?.setTitle("Cancel", for: .normal)
uiButton?.setTitleColor(UIColor.white,for: .normal)

Answer 16

UITextAttribute从IOS 7使用以下用于IOS 7或更高版本

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

Answer 17

对于使用Swift的人，我必须先添加 Eddie K's extension

然后我能够这样称呼它（基本上是Sabo在接受的答案中所做的）：

UIBarButtonItem.appearanceWhenContainedWithin(UISearchBar.self).setTitleTextAttributes()

如何在iOS 7中更改文本UISearchBar的取消按钮颜色？
