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);
}
