更改 UISearchbar 放大镜颜色、占位符颜色和 X 颜色

Question

我已经搜索了各种解决方案来完成此任务，但它们要么在目标 C 中，要么涉及替换放大镜图像。

我看过的以前的帖子：

改变放大镜的颜色

如何更改 UISearchBar 占位符和图像色调颜色？

我不想更换放大镜图像的原因是因为页面颜色是动态的并且有超过100+的颜色组合

任何有关更改 UISearchbar 放大镜颜色、占位符颜色和 X 颜色的帮助将不胜感激

Answer 1

目标C：

NSArray *searchBarSubViews = [[self.searchBar.subviews objectAtIndex:0] subviews];
for (UIView *view in searchBarSubViews) {
    if([view isKindOfClass:[UITextField class]])
    {
        UITextField *textField = (UITextField*)view;
        UIImageView *imgView = (UIImageView*)textField.leftView;
        imgView.image = [imgView.image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];
        imgView.tintColor = [UIColor whiteColor];

        UIButton *btnClear = (UIButton*)[textField valueForKey:@"clearButton"];
        [btnClear setImage:[btnClear.imageView.image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate] forState:UIControlStateNormal];
        btnClear.tintColor = [UIColor whiteColor];

    }
}
[self.searchBar reloadInputViews];

斯威夫特：

// Text field in search bar.
let textField = searchController.searchBar.valueForKey("searchField") as! UITextField

let glassIconView = textField.leftView as! UIImageView
glassIconView.image = glassIconView.image?.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate)
glassIconView.tintColor = UIColor.whiteColor()

let clearButton = textField.valueForKey("clearButton") as! UIButton
clearButton.setImage(clearButton.imageView?.image?.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate), forState: .Normal)
clearButton.tintColor = UIColor.whiteColor()

Answer 2

Shahil 的答案针对 Swift 3 进行了更新：

let textField = searchBar.value(forKey: "searchField") as! UITextField

let glassIconView = textField.leftView as! UIImageView
glassIconView.image = glassIconView.image?.withRenderingMode(.alwaysTemplate)
glassIconView.tintColor = .white


let clearButton = textField.value(forKey: "clearButton") as! UIButton
clearButton.setImage(clearButton.imageView?.image?.withRenderingMode(.alwaysTemplate), for: .normal)
clearButton.tintColor = .white

Answer 3

func setupPlaceHolder(text: String, textColor: UIColor) {
  searchBar.searchTextField.attributedPlaceholder = NSAttributedString(
    string: text,
    attributes: [.foregroundColor: textColor]
  )
        
  searchBar.searchTextField.leftView?.tintColor = .white
}

2024 年

class UsableUISearchBar: UISearchBar {
    
    override init(frame: CGRect) {
        
        super.init(frame: frame)
        common()
    }

    required init?(coder aDecoder: NSCoder) {
        
        super.init(coder: aDecoder)
        common()
    }

    func common() {
        barTintColor = .clear
        searchTextField.backgroundColor = .darkGray
        searchTextField.leftView?.tintColor = .white
    }
}

是的，init 似乎已经晚到无法设置颜色了。 （显然，根据您的房屋风格，您可以在布局中做到这一点。）
