当渐变应用于导航栏时，如何更改状态栏的颜色？

我想在导航栏上应用渐变色。 我申请了，但状态栏颜色没有变化。 谁能帮我这个？

以下是实现渐变颜色的代码：

let colorTop = UIColor(red: 69/255, green: 90/255, blue: 195/255, alpha: 1.0).CGColor let colorBottom = UIColor(red: 230/255, green: 44/255, blue: 75/255, alpha: 1.0).CGColor let gradientLayer = CAGradientLayer() gradientLayer.colors = [ colorTop, colorBottom] gradientLayer.locations = [ 0.0, 1.0] gradientLayer.frame = CGRectMake(0, 0, 375, 64) self.navigationController?.navigationBar.layer.addSublayer(gradientLayer) 

Answer 1

用这个：

 gradientLayer.frame = CGRect(x:0, y:-20, width:375, height:64) 

输出：

在Swift3中：

  let colorTop = UIColor(red: 69/255, green: 90/255, blue: 195/255, alpha: 1.0).cgColor let colorBottom = UIColor(red: 230/255, green: 44/255, blue: 75/255, alpha: 1.0).cgColor let gradientLayer = CAGradientLayer() gradientLayer.colors = [ colorTop, colorBottom] gradientLayer.locations = [ 0.0, 1.0] gradientLayer.frame = CGRect(x:0, y:-20, width:375, height:64) self.navigationController?.navigationBar.layer.addSublayer(gradientLayer) 

Answer 2

更换

  self.navigationController?.navigationBar.layer.addSublayer(gradientLayer) with self.navigationController?.navigationBar.layer.sublayers?.insert(gradientLayer, at: 0) 

使用上面的代码构建后添加了图像
