在iMessage应用程序中检查横向/纵向方向(扩展名) [英] Check Landscape/Portrait orientation in an iMessage app (extension)
问题描述
已经看到很多方法来检查方向,但奇怪的是,没有工作!!
Have seen a lot of solutions to check the orientation, but strangely, none works!!
下面是代码片段,
override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {
let screenSize = UIScreen.main.bounds
let screenWidth = screenSize.width
let screenHeight = screenSize.height
print("Screen Width = \(screenWidth)")
print("Screen Height = \(screenHeight)")
if (screenWidth > screenHeight) {
print("Landscape")
alertView.removeFromSuperview()
messageView.addGestureRecognizer(tapTextView)
}
else {
print("Portrait")
setupLandscapeAlertView()
}
}
另一种用于设置视图的方法是,
The other method which is used to setup the view is,
fileprivate func setupLandscapeAlertView() {
messageView.removeGestureRecognizer(tapTextView)
alertView = UIView(frame: CGRect(x: 0, y: 0, width: self.view.bounds.width, height: self.view.bounds.height))
alertView.backgroundColor = UIColor.clear
alertView.isUserInteractionEnabled = false
let transparentView = UIView(frame: CGRect(x: 0, y: 0, width: self.view.frame.height, height: self.view.frame.width))
transparentView.backgroundColor = UIColor.gray
transparentView.backgroundColor = transparentView.backgroundColor!.withAlphaComponent(0.6)
transparentView.isUserInteractionEnabled = false
alertView.addSubview(transparentView)
let blurEffect = UIBlurEffect(style: .regular)
let blurredEffectView = UIVisualEffectView(effect: blurEffect)
blurredEffectView.frame = transparentView.bounds
blurredEffectView.isUserInteractionEnabled = false
alertView.addSubview(blurredEffectView)
let imageView = UIImageView(image: UIImage(named: "LandscapeAlert"))
imageView.frame = CGRect(x: 70, y: 75, width: imageView.frame.width, height: imageView.frame.height)
imageView.contentMode = UIViewContentMode.scaleAspectFit
imageView.contentMode = UIViewContentMode.center
imageView.isUserInteractionEnabled = false
alertView.addSubview(imageView)
self.view.addSubview(alertView)
}
另一件事是,此图像不居中。我该怎么做?同样,太多的解决方案,但没有任何工作。
Another thing is that, this image isn't centered. How do I go about that? Again, too many solutions, but nothing does the job.
不确定我做错了什么。 : - /
Not sure if I'm doing anything wrong. :-/
推荐答案
这可能是因为 viewWillTransition
在视图之前执行实际上是翻转。如果你在打印(height width \(view.frame.height)\(view.frame.width))
> viewWillTransition 阻止你会看到。
This may be because viewWillTransition
executes before the view actually flips. If you do a simple print("height width \(view.frame.height) \(view.frame.width)")
inside the viewWillTransition
block you will see.
