我想将右栏按钮项的颜色从黑色更改为白色.它是一个按钮作为搜索图标.我还没有对搜索实现进行编码,因为我想首先完成主界面.我以为我写了正确的代码所以它应该显示为白色,但它在故事板和模拟器中似乎仍然显示为黑色.
在故事板中,我还将其设置为白色.
这是我的代码,它位于AppDelegate.swift文件中:
func application(application: UIApplication,didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool { // Changing the status bar's colour to white UIApplication.sharedApplication().statusBarStyle = .LightContent // Changing the navigation controller's background colour UINavigationBar.appearance().barTintColor = UIColor(red: 0.0/255.0,green: 165.0/255.0,blue: 227.0/255.0,alpha: 1.0) // Changing the navigation controller's title colour UINavigationBar.appearance().titleTextAttributes = [NSForegroundColorAttributeName: UIColor.whiteColor()] // Changing the colour of the bar button items UINavigationBar.appearance().tintColor = UIColor.whiteColor() // Changing the tint colour of the tab bar icons UITabBar.appearance().tintColor = UIColor(red: 0.0/255/0,alpha: 1.0) return true }
这是模拟器的图像:
解决方法
SWIFT 4
将自定义barbuttonitem声明为插座后:
@IBOutlet weak var yourBarButtonItem: UIBarButtonItem!
您可以根据需要定义颜色.
yourBarButtonItem.tintColor = .red
