[英]How to remove a copied preview phone in Xcode 13?
When I click the following button on the top of a preview phone, Xcode copies the preview phone for me.当我点击预览手机顶部的以下按钮时,Xcode 会为我复制预览手机。 So if there is only one preview phone before clicking the button, there are two afterward.
因此,如果在单击按钮之前只有一部预览手机,则之后会有两部。
My question is: How to remove the copied preview phone?我的问题是:如何删除复制的预览手机?
Previews only happen because your code says they should happen.预览只会发生,因为你的代码说它们应该发生。 All this button really does is to modify the code that generates the preview(s).
这个按钮真正做的就是修改生成预览的代码。 For example:
例如:
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
Group {
ContentView()
ContentView()
}
}
}
See how it says ContentView()
twice?看看它是怎么说
ContentView()
两次的? That's two previews.这是两个预览。 To remove the second preview, revert the change.
要删除第二个预览,请还原更改。 For example:
例如:
struct ContentView_Previews: PreviewProvider {
static var previews: some View {
ContentView()
}
}
