Could you help to resolve this problem : to set the background color of status bar like color of navigation bar for a view ? Thank you.

Answer 1

您可以使用：

UIApplication.sharedApplication().setStatusBarStyle(UIStatusBarStyle.LightContent, animated: true)

Answer 2

You can change the color of status bar if you are using the gradient layer.Here is the code just try it and do let me know.

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, -20, 375, 64)

  self.navigationController?.navigationBar.layer.addSublayer(gradientLayer)
