II /打开yourViewController.swift文件并插入：

override func prefersStatusBarHidden() -> Bool {
    // Return false -> Show statusBar
    return false
}

override func preferredStatusBarStyle() -> UIStatusBarStyle {
    // Change status background color
    let statusBar: UIView = UIApplication.sharedApplication().valueForKey("statusBar") as! UIView
    if statusBar.respondsToSelector(Selector("setBackgroundColor:")) {
        statusBar.backgroundColor = UIColor.redColor()
    }
    // Change textColor -> While(LightContent)
    return UIStatusBarStyle.LightContent
}
