问题 Why some people make it duplicate? I I said that was my question... First, I own this question and now I want to show a better example of my question. Honestly, I didn't try the answer yet because I'm curious is there anyway to solved this by code? Well, is it even possible? Besides, using an image as a background to solve this would be a problem, no? I mean, the user's phone is not always has the same screen size. Here's an example of the idle state of my home screen.

问题 There was a property in the initializer with ScrollView(alwaysBounceVertical: false) but I cant't seem to find it anymore. Does anyone know how I can disable the vertical bounce / overscroll on a SwiftUI ScrollView? 回答1: Yes, it has been removed from the initializer of ScrollView, now you have to update the appearance of the UIScrollView in order to restrict the scrolling.

(Note that if we remove VStack the behavior does not change.) var body: some View { ScrollView.init([.vertical,.horizontal]) { VStack { Text("AAA") .padding(8) .frame(width: 1024, height: 1024) .background(Color.orange) .border(Color.red) } } .border(Color.blue) } In this image is as far to the left and up

问题 Is there any possibility to prevent the keyboard from dismissing when scrolling a FlatList ? When using a ScrollView setting the prop "keyboardDismissMode" to "none" is the solution to this problem, but this doesn't work for me at a FlatList... I use the FlatList inside a self-made component, that is in a Stack-Navigator, while there is a focussed TextInput in its header. I render the FlatList like this: <View style={{flex: 1}}> <FlatList style={{flex: 1}} data={this.props.data} keyExtractor=

问题 I make a collapsing tollbar in ReactNative and i need stop de animation when the Animated.ScrollView contentOffset.y is equal 240.

问题 i'm trying to code a simple login page on my app. I started using SwiftUI on my newlly updated Mac OS Catalina. The Apple documentation is still lacking a lot. I need to center a VStack vertically on a Scrollview ocupying the whole page with a "limit" on it's width of 400.
