[英]Center Scroll View content
I have centered my Scroll View by using GeometryReader like this:我使用 GeometryReader 将我的滚动视图居中,如下所示:
struct ContentView: View {
var body: some View {
NavigationView {
GeometryReader { geom in
ScrollView(.vertical, showsIndicators: false) {
ZStack {
my_super_view()
}
.navigationBarTitle("Main")
.frame(width: geom.size.width)
.frame(minHeight: geom.size.height)
}
}
}.navigationViewStyle(StackNavigationViewStyle())
}
}
And it works almost great.它几乎很好用。 My problem is that the height of container ZStack is too big and the page could be scrolled down like this:
我的问题是容器 ZStack 的高度太大,页面可以像这样向下滚动:
And when i try to do smth like:
当我尝试做某事时:
.frame(minHeight: geom.size.height-52)
The page stops scrolling, but is poorly centered.页面停止滚动,但居中不佳。 How can I properly center the page so that it fits entirely on the main screen without scrolling below it?
如何正确地将页面居中,使其完全适合主屏幕而无需在其下方滚动?
UPD: I found out that i could use position() instead of frame(). UPD:我发现我可以使用 position() 而不是 frame()。 In that case page centred properly, but it may cause some issues in future.
在这种情况下,页面正确居中,但将来可能会导致一些问题。
struct ContentView: View {
var body: some View {
NavigationView {
GeometryReader { geom in
ScrollView(.vertical, showsIndicators: false) {
ZStack {
my_super_view()
}
.navigationBarTitle("Main")
.position(x: geom.size.width/2, y: geom.size.height/2)
}
}
.navigationBarTitle("Диа Компаньон")
.navigationBarTitleDisplayMode(.inline)
}.navigationViewStyle(StackNavigationViewStyle())
}
}
I had to use .inline
NavigationBarDisplayMode and position
instead of setting up width and height of ZStack我不得不使用
.inline
NavigationBarDisplayMode 和position
而不是设置 ZStack 的宽度和高度
