DYPopoverView example

Code example: Content View (your main view)

DYPopoverView needs to be attached to another view by adding the anchorView modifier to it including a view id. Alternatively, it can be initialized with an anchorFrame - make sure to attach the anchorFrame modifier to your anchor view instead of the anchorView id. The anchor view can be several levels below in the view hierarchy relative to the view that you apply the popoverView-modifier to. See the following example for details.


import DYPopoverView

struct PopoverPlayground: View {
    
    @State private var showSecondPopover = false
    @State private var showFirstPopover  = false
    @State private var showNavPopover = false
    
    @State private var navBarPopoverOriginFrame: CGRect = .zero
    @State private var secondPopoverFrame = CGRect(x: 0, y: 0, width: UIScreen.main.bounds.width * 0.75, height:150 )

    @State private  var popoverPosition: ViewPosition = .top
    
    var body: some View {
        GeometryReader {  proxy in
            NavigationView {
                
                    VStack(alignment: .center) {
               
                    Spacer()
                  
                    Button(action: {

                        self.showFirstPopover.toggle()
                           
                       }) {
                           TranslucentTextButtonView(title: "Popout", foregroundColor: .red, backgroundColor: .red, frameWidth: 100)
                    }.anchorView(viewId: "firstPopover").padding()
                           
                        Button(action: {
                           // self.viewId = "1"
                            self.showSecondPopover.toggle()
                          }) {
                            TranslucentTextButtonView(title: "Popover", foregroundColor: .accentColor, backgroundColor: .accentColor, frameWidth: 100).anchorView(viewId: "secondPopover")
                        }

                        Spacer()
                    
                        Picker("", selection: self.$popoverPosition) {
                            ForEach(0 ..< ViewPosition.allCases.count) {
                                Text(ViewPosition.allCases[$0].rawValue).tag(ViewPosition.allCases[$0])
                            }
                        }
                         
                    }
                    .frame(width: proxy.size.width).background(Color(.systemBackground))

                    .navigationBarItems(trailing: self.navBarButton )
                    .navigationTitle(Text("Test"))
              }
            .popoverView(content: { Text("Content")}, background: { Color(.secondarySystemBackground).onTapGesture {
                self.showNavPopover = false
            } }, isPresented: self.$showNavPopover, frame: .constant(CGRect(x:0, y:0, width: 200, height: 200)), anchorFrame: self.navBarPopoverOriginFrame, popoverType: .popout, position: .bottomLeft, viewId: "")
            .popoverView(content: {Text("Some content")}, background: {BlurView(style: .systemChromeMaterial)}, isPresented: self.$showFirstPopover, frame: .constant(CGRect(x: 0, y: 0, width: 150, height: 150)),  anchorFrame: nil, popoverType: .popout, position: self.popoverPosition, viewId: "firstPopover", settings: DYPopoverViewSettings(shadowRadius: 20))
            .popoverView(content: {ContentExample(frame: self.$secondPopoverFrame, show:self.$showSecondPopover)}, background: {Color(.secondarySystemBackground)}, isPresented: self.$showSecondPopover, frame: self.$secondPopoverFrame, anchorFrame: nil, popoverType: .popover, position: self.popoverPosition, viewId: "secondPopover", settings: DYPopoverViewSettings(cornerRadius: (30, 30, 30, 30)))
            
        }
    }
    
    var navBarButton: some View {
        Button(action: {
            self.showNavPopover.toggle()
        }, label: {
            Text("Pop")
        })
        .anchorFrame(rect: self.$navBarPopoverOriginFrame)
    }

Change log

Version1.1.1

Minor changes.

Version 1.1

Added alternative way to initialize popover - with an anchorFrame instead of a view id. If the anchor view is a NavigationBar item, the popover does not always appear properly if initialized with a view id.

Version 1.0.1

slight improvment for navigation item as anchor view.

Version 1.0

Initializer changed - added background. Removed backgroundColor from settings.

Version 0.2

Initializer changed - the content view needs to be put in a closure instead of casting it to AnyView.

Version 0.1

Initial public release.
