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

在iOS8中,如果你设置UINavigationBar。你可以设置酒吧的背景为无边框的素色。
迅速:
UINavigationBar.appearance().translucent = false
UINavigationBar.appearance().barStyle = UIBarStyle.Black
UINavigationBar.appearance().barTintColor = UIColor.redColor()
其他回答
你应该在UISearchBar的底部添加一个视图
let rect = searchController.searchBar.frame;
let lineView : UIView = UIView.init(frame: CGRect.init(x: 0, y: rect.size.height-1, width: rect.size.width, height: 1))
lineView.backgroundColor = UIColor.init(hexString: "8CC73E")
searchController.searchBar.addSubview(lineView)
Slightly Swift Solution
func setGlobalAppearanceCharacteristics () {
let navigationBarAppearace = UINavigationBar.appearance()
navigationBarAppearace.tintColor = UIColor.white
navigationBarAppearace.barTintColor = UIColor.blue
navigationBarAppearace.setBackgroundImage(UIImage(), for: UIBarMetrics.default)
navigationBarAppearace.shadowImage = UIImage()
}
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)
我刚刚为这个创建了一个扩展…关于格式的问题很抱歉(这是我的第一个答案)。
用法:
override func viewDidLoad() {
super.viewDidLoad()
self.navigationController?.hideShadow = true
}
扩展:
UINavigationController.swift
// Created by Ricardo López Rey on 16/7/15.
import Foundation
struct UINavigationControllerExtension {
static var hideShadowKey : String = "HideShadow"
static let backColor = UIColor(red: 247/255, green: 247/255, blue: 248/255, alpha: 1.0)
}
extension UINavigationController {
var hideShadow : Bool {
get {
if let ret = objc_getAssociatedObject(self, &UINavigationControllerExtension.hideShadowKey) as? Bool {
return ret
} else {
return false
}
}
set {
objc_setAssociatedObject(self,&UINavigationControllerExtension.hideShadowKey,newValue, objc_AssociationPolicy(OBJC_ASSOCIATION_RETAIN_NONATOMIC))
if newValue {
self.navigationBar.setBackgroundImage(solidImage(UINavigationControllerExtension.backColor), forBarMetrics: UIBarMetrics.Default)
self.navigationBar.shadowImage = solidImage(UIColor.clearColor())
} else {
self.navigationBar.setBackgroundImage(nil, forBarMetrics: UIBarMetrics.Default)
}
}
}
private func solidImage(color: UIColor, size: CGSize = CGSize(width: 1,height: 1)) -> UIImage {
var rect = CGRectMake(0, 0, size.width, size.height)
UIGraphicsBeginImageContextWithOptions(size, false, 0)
color.setFill()
UIRectFill(rect)
var image: UIImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
return image
}
}
酒吧风格的黑色适合我。
[[UINavigationBar appearance] setBarStyle:UIBarStyleBlack];
我拥有的所有属性(以防万一):
[[UINavigationBar appearance] setBarTintColor:color];
[[UINavigationBar appearance] setTranslucent:NO];
[[UINavigationBar appearance] setShadowImage:[UIImage new]];
[[UINavigationBar appearance] setBarStyle:UIBarStyleBlack];
