导航栏的景观视图问题 [英] Landscape view issue with navigation bar

问题描述

默认导航栏高度为64.但是将其更改为横向导航栏高度的方向更改为28.我想在所有方向上设置固定导航栏大小".

Default Navigation bar height is 64.But after change it's orientation to landscape navigation bar height changed to 28.I want to set Fix navigation bar size in all orientation.

推荐答案

您可以添加方向观察器:

You can add orientation observer:

NotificationCenter.default.addObserver(self, selector: #selector(rotated), name: NSNotification.Name.UIDeviceOrientationDidChange, object: nil)

并添加旋转方法:

func rotated() {
    let height: CGFloat = 50 //whatever height you want to add to the existing height
    let bounds = self.navigationController!.navigationBar.bounds
    self.navigationController?.navigationBar.frame = CGRect(x: 0, y: 0, width: bounds.width, height: bounds.height + height)
}
