我有两个图像 bg-land
和 bg-port
用于不同的方向。我想改变改变方向的形象。但是,图像不会改变。当我在 LandScape 中加载模拟器时,bg-land
工作完美但不适用于旋转。代码:
override func viewDidLoad() {
super.viewDidLoad()
loadBackground()
}
func loadBackground(){
if(UIApplication.sharedApplication().statusBarOrientation.isPortrait){
var bgImage = UIImage(named: "bg-port")
var background = UIImageView(frame: self.view.bounds);
background.image = bgImage
self.view.addSubview(background)
self.view.sendSubviewToBack(background)
println(bgImage)
} else {
var bgImage = UIImage(named: "bg-land")
var background = UIImageView(frame: self.view.bounds);
background.image = bgImage
self.view.addSubview(background)
self.view.sendSubviewToBack(background)
println(bgImage)
}
}
override func didRotateFromInterfaceOrientation(fromInterfaceOrientation: UIInterfaceOrientation) {
loadBackground()
}
最佳答案
这段代码对我来说很好,试试这个:
override func viewDidLoad() {
super.viewDidLoad()
self.loadBackground()
}
func loadBackground(){
if(UIApplication.sharedApplication().statusBarOrientation.isPortrait){
let imageName = "Texture.jpg"
let image = UIImage(named: imageName)
let imageView = UIImageView(image: image!)
imageView.frame = self.view.bounds
view.addSubview(imageView)
} else {
let imageName = "AppIcon.png"
let image = UIImage(named: imageName)
let imageView = UIImageView(image: image!)
imageView.frame = self.view.bounds
view.addSubview(imageView)
}
}
override func didRotateFromInterfaceOrientation(fromInterfaceOrientation: UIInterfaceOrientation) {
loadBackground()
}
不要忘记在此代码中更改图像名称。
也许这会对你有所帮助。
