如何从纵向模式更改为横向模式并锁定它?
问题描述:
我有一个电影视图压缩在肖像模式的右下视口。当用户展开电影视图时,电影视图将以横向模式展开为全屏。无论设备是什么方向,我也想在全屏幕时将电影视图锁定到横向模式。如何从纵向模式更改为横向模式并锁定它?
注意:我所有的其他视图都处于肖像模式。
我已经参考本post与此代码,
应用设置,
AppDelegate.swift
internal var shouldRotate = false
func application(_ application: UIApplication,
supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
return shouldRotate ? .allButUpsideDown : .portrait
}
视图控制器,
func expandPlayerWindow(button: UIButton) {
self.player.view.frame = CGRect(x:0, y:-20, width: UIScreen.main.bounds.maxY, height: UIScreen.main.bounds.maxX)
let appDelegate = UIApplication.shared.delegate as! AppDelegate
print(appDelegate.shouldRotate)
print(self.supportedInterfaceOrientations)
appDelegate.shouldRotate = true // or false to disable rotation
let value = UIInterfaceOrientation.landscapeLeft.rawValue
UIDevice.current.setValue(value, forKey: "orientation")
print(appDelegate.shouldRotate)
print(self.supportedInterfaceOrientations)
appDelegate.shouldRotate = false
print(appDelegate.shouldRotate)
print(self.supportedInterfaceOrientations)
UIApplication.shared.isStatusBarHidden = false
}
日志,
false
UIInterfaceOrientationMask(rawValue: 26)
true
UIInterfaceOrientationMask(rawValue: 26)
false
UIInterfaceOrientationMask(rawValue: 26)
我setorientation之前设置shouldRotate为true,本作视图可以改变为横向模式。设置方向后,我将shoudRotate设置为false以禁用旋转。然后我测试它,当我点击按钮时,电影视图改变为风景,在我旋转设备后,电影视图改变为肖像,并锁定到肖像模式而不是风景模式。
答
它是由该功能引起的,
func application(_ application: UIApplication,
supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
return shouldRotate ? .allButUpsideDown : .portrait
}
变化.allButUpsideDown
到.landscape
会做。
可行的代码,
AppDelegate.swift
func application(_ application: UIApplication,
supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
return shouldRotate ? .landscape : .portrait
}
视图控制器,
func expandPlayerWindow() {
self.player.view.frame = CGRect(x:0, y:-20, width: UIScreen.main.bounds.maxY, height: UIScreen.main.bounds.maxX)
let appDelegate = UIApplication.shared.delegate as! AppDelegate
appDelegate.shouldRotate = true // or false to disable rotation
let value = UIInterfaceOrientation.landscapeLeft.rawValue
UIDevice.current.setValue(value, forKey: "orientation")
appDelegate.shouldRotate = true
UIApplication.shared.isStatusBarHidden = true
}
怎么样的电影视图的父视图。你是否阻止他们旋转? –
是的,我认为阻止它们不仅仅是电影视图。 –
您的电影是否查看视图控制器的视图,以及视图控制器是否在每种模式下为shouldAutorotate和supportedInterfaceOrientations返回适当的值? –
