正常的屏幕显示应该是
竖屏导航栏高度 状态栏高度 44px(内容区)横屏导航栏高度 44px(仅内容区)
问题原因
屏幕旋转时系统信息如状态栏高度会发生变化在横竖屏切换过程中获取系统信息可能存在时序问题导致获取到的状态栏高度不准确
解决方案
监听屏幕旋转事件 wx.onWindowResize通过比较窗口宽高来判断是否横屏windowWidth windowHeight在横屏时将状态栏高度设置为0竖屏时使用系统实际状态栏高度使用 setTimeout 延迟更新导航栏状态确保系统信息已完全更新在组件销毁时记得解绑旋转事件监听器 wx.offWindowResize()
下面是具体custom-navbar组件的代码这里只是适用我的项目应该不是完美的方案有更好的方案欢迎大家沟通
