swift2.0 如何隐藏和设置状态栏

1、在ViewController中操作当前ViewController的状态栏
/**
隐藏状态栏
*/
override func prefersStatusBarHidden() -> Bool {
    return true;
}  

/**
设置状态栏风格
*/
override func preferredStatusBarStyle() -> UIStatusBarStyle {
    return UIStatusBarStyle.LightContent;
}

2.在AppDelegate中设置状态栏
func setupWithStatusBar(application: UIApplication) {
    // 设置状态栏隐藏
    application.statusBarHidden = true;
    application.setStatusBarHidden(true, withAnimation: UIStatusBarAnimation.Fade);
    // 设置状态栏高亮
    application.statusBarStyle = UIStatusBarStyle.LightContent;
    application.setStatusBarStyle(UIStatusBarStyle.LightContent, animated: true);
}
