SearchBar，如何更改文字颜色？

Question

我的搜索栏有默认的灰色文字，但我希望它是白色文字。我无法弄清楚如何使用swift来更改范围栏文本颜色，并且您无法从故事板中执行此操作。我发现的最接近的是

searchBarOutlet.setScopeBarButtonTitleTextAttributes([NSForegroundColorAttributeName: UIColor.whiteColor()], forState:UIControlState.Normal)

但是这也无济于事。有什么想法吗？

Answer 1

有点难以访问UISearchbar内的Textfield。

这是它的工作原理：

for subView in self.searchBarOutlet.subviews
    {
        for secondLevelSubview in subView.subviews
        {
            if (secondLevelSubview.isKindOfClass(UITextField))
            {
                if let searchBarTextField:UITextField = secondLevelSubview as? UITextField
                {
                    //set the color here like this:
                    searchBarTextField.textColor = UIColor.redColor()
                    break;
                }

            }
        }
    }

更短的解决方案：

var textFieldInsideSearchBar = yourSearchbar.valueForKey(“searchField”) as? UITextField 
textFieldInsideSearchBar?.textColor = yourcolor

Answer 2

// My preferred way of accessing searchField

if let searchTextField = self.searchBar.valueForKey("searchField") as? UITextField {

  searchTextField.textAlignment = NSTextAlignment.Left

}

Answer 3

Swift 3

UITextField.appearance(whenContainedInInstancesOf: [UISearchBar.self]).textColor = UIColor.white

Answer 4

在我的swift 3.0案例中

（mySearchBar.value（forKey：＆＃34; searchField＆＃34;）as？UITextField）?. textColor = UIColor.white

Answer 5

searchBar.searchTextField.textColor = .white
