Answer 1

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)

Answer 2

如果您只想设置按钮的文本颜色,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

一种更简单的方式 - >

self.searchbar.tintColor = [UIColor darkGrayColor];

Answer 5

您可以更改UISearchBar此类似的子视图- (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];
    }
}

Answer 6

为**工作 Swift 5

使用模块SWIFT 4功能appearance-

方法1: -加载时显示取消按钮UIAppearance-

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

要么 -

方法2: - searchBar点击后显示取消按钮颜色-

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

Answer 7

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"];
