Chh*_*oro 3 textcolor uisearchbar swift
我谷歌几个小时如何更改我的UISearchBar字体大小和颜色,但我不能与之相关的任何文件.
这是我到目前为止在swift 4上所做的:
searchBar = UISearchBar(frame: CGRect(x: 0, y: 0, width: view.frame.width - (menuImage.frame.width + iconImage.frame.width + 55), height: 30))
searchBar.placeholder = "SEARCH BAR"
searchBar.tintColor = UIColor.gray
searchBar.delegate = self
searchBar.font = [UIFont fontWithName:@"Oswald" size:11];

要更改文本和占位符搜索栏:
// SearchBar text
let textFieldInsideUISearchBar = searchBar.value(forKey: "searchField") as? UITextField
textFieldInsideUISearchBar?.textColor = UIColor.red
textFieldInsideUISearchBar?.font = textFieldInsideUISearchBar?.font?.withSize(12)
// SearchBar placeholder
let textFieldInsideUISearchBarLabel = textFieldInsideUISearchBar!.value(forKey: "placeholderLabel") as? UILabel
textFieldInsideUISearchBarLabel?.textColor = UIColor.red

以下是在最新的 Swift 上更改字体和文本颜色的方法:
let attributes = [NSAttributedString.Key.font: UIFont.boldSystemFont(15), NSAttributedString.Key.foregroundColor: UIColor.gray]
UITextField.appearance(whenContainedInInstancesOf: [UISearchBar.self]).defaultTextAttributes = attributes

在 iOS 13 或最新版本中,UISearchBar 有一个名为searchTextField. 但早些时候,我们不能使用这个属性。
所以,我们可以为 UISearchBar 扩展:
extension UISearchBar {
var textField: UITextField? {
if #available(iOS 13.0, *) {
return self.searchTextField
} else {
// Fallback on earlier versions
for view in (self.subviews[0]).subviews {
if let textField = view as? UITextField {
return textField
}
}
}
return nil
}
}

并使用:
searchBar.textField?.font = UIFont.systemFont(ofSize: 12)
