我有一个应用程序,有时需要它的导航栏融入内容。
有人知道怎么去掉或者改变这个烦人的小条的颜色吗?
在下图中,我说的是根视图控制器下面1px的高度线

编写自己的初始化式:D
import Foundation
import UIKit
extension UINavigationController {
convenience init(rootViewController : UIViewController, hidesShadow : Bool) {
self.init(rootViewController : rootViewController)
self.navigationBar.setValue(hidesShadow, forKey: "hidesShadow")
if hidesShadow {
self.extendedLayoutIncludesOpaqueBars = true
self.navigationBar.isTranslucent = false
}
}
}
其他回答
这可能听起来很愚蠢,但这个发际线只在viewController视图的背景色被设置为任何颜色时出现,除了白色。得知这个事实我很震惊。
如果你想让它毫不费力地消失只要设置控制器视图背景色为WHITE color。
两条线的解决方案对我来说很有效。尝试在ViewDidLoad方法中添加这个:
navigationController?.navigationBar.setValue(true, forKey: "hidesShadow")
self.extendedLayoutIncludesOpaqueBars = true
以上问题的答案
//删除1px的导航条线
[[UINavigationBar appearance] setBackgroundImage:[[UIImage alloc]init] forBarMetrics:UIBarMetricsDefault];
[[UINavigationBar appearance] setShadowImage:[[UIImage alloc] init]];
[[UINavigationBar appearance] setTranslucent:NO];
[[UINavigationBar appearance] setTintColor:[UIColor yourColor]];
简单的解决方案- Swift 5
Create an extension: extension UIImage { class func hideNavBarLine(color: UIColor) -> UIImage? { let rect = CGRect(x: 0, y: 0, width: 1, height: 1) UIGraphicsBeginImageContext(rect.size) let context = UIGraphicsGetCurrentContext() context?.setFillColor(color.cgColor) context?.fill(rect) let navBarLine = UIGraphicsGetImageFromCurrentImageContext() UIGraphicsEndImageContext() return navBarLine } } Add this to viewDidLoad(): self.navigationController?.navigationBar.shadowImage = UIImage.hideNavBarLine(color: UIColor.clear)
if #available(iOS 13.0, *) {
let appearance = UINavigationBarAppearance()
appearance.backgroundColor = Colors.color_app
appearance.titleTextAttributes = [.foregroundColor : UIColor.white]
appearance.largeTitleTextAttributes = [.foregroundColor : UIColor.white]
appearance.shadowColor = .clear
appearance.shadowImage = UIImage()
UINavigationBar.appearance().tintColor = .white
UINavigationBar.appearance().standardAppearance = appearance
UINavigationBar.appearance().compactAppearance = appearance
UINavigationBar.appearance().scrollEdgeAppearance = appearance
} else {
UINavigationBar.appearance().barTintColor = Colors.color_app
UINavigationBar.appearance().tintColor = .white
UINavigationBar.appearance().titleTextAttributes = [NSAttributedString.Key.foregroundColor : UIColor.white]
if #available(iOS 11.0, *) {
UINavigationBar.appearance().largeTitleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.white]
}
UINavigationBar.appearance().isTranslucent = false
UINavigationBar.appearance().shadowImage = UIImage()
UINavigationBar.appearance().setBackgroundImage(UIImage(), for: .default)
}
