A family of objects that can be used to "spy" on a View and collect its frame (a CGRect describing position and size) relative to a coordinate space.
import FrameSpy
struct ContentView: View {
var body: some View {
VStack(spacing: 10.0) {
Text("Text 1")
}
.coordinateSpace(name: "ContentView") // the coordinate space is now named "ContentView".
}
}import FrameSpy
struct ContentView: View {
@State var spiedFrames: SpiedFramesBag = SpiedFramesBag() // spied frames will be collected here.
var body: some View {
VStack(spacing: 10.0) {
Text("Text 1")
}
.coordinateSpace(name: "ContentView")
}
}import FrameSpy
struct ContentView: View {
@State var spiedFrames: SpiedFramesBag = SpiedFramesBag()
var body: some View {
VStack(spacing: 10.0) {
Text("Text 1")
.spyFrame(named: "text-1", inCoordinateSpaceNamed: "ContentView") // This `Text`s frame is now "spied" in the coordinate space "ContentView". The spied frame's name is "text-1"
}
.coordinateSpace(name: "ContentView")
}
}4. Collect the spied frame(s) in the bag declared in step 1 using the .collectSpiedFrames(into:) ViewModifier.
import FrameSpy
struct ContentView: View {
@State var spiedFrames: SpiedFramesBag = SpiedFramesBag()
var body: some View {
VStack(spacing: 10.0) {
Text("Text 1")
.spyFrame(named: "text-1", inCoordinateSpaceNamed: "ContentView")
}
.coordinateSpace(name: "ContentView")
.collectSpiedFrames(into: $spiedFrames) // The spied frames will be collected into `$spiedFrames`
}
}The frame for the Text will be available as spiedFrames["text-1"]. Remember this value is Optional and might not be always available.
