iOS SwiftUI - use NavigationLink and perform additional action-CodePudding

            NavigationLink(destination: ShowWebView(showWhat: "privacy"), label: {
                HStack(spacing: 32) {
                    
                    Image(systemName: "info.square")
                        .font(.title2)
                        .frame(width: 26)
                    
                    Text("privacy_policy")
                    
                }
                .frame(minWidth: 0, maxWidth: .infinity, alignment: .leading)
            })

I need to perform additional action when opening ShowWebView.

This is what I've tried:

            NavigationLink(destination: ShowWebView(showWhat: "privacy"), label: {
                HStack(spacing: 32) {
                    
                    Image(systemName: "info.square")
                        .font(.title2)
                        .frame(width: 26)
                    
                    Text("privacy_policy")
                    
                }
                .frame(minWidth: 0, maxWidth: .infinity, alignment: .leading)
                .onTapGesture {
                    withAnimation(){
                        self.offsetMenu = UIScreen.main.bounds.height
                    }
                }
            })

but this way only what's inside onTapGesture is performed but the view ShowWebView doesn't get opened.

CodePudding user response：

You can change the variable applying the .onAppear modifier to ShowWebView.

This is the code to obtain what you are looking for:

NavigationLink {
    ShowWebView(showWhat: "privacy")

        // Add this modifier
        .onAppear {
            withAnimation {
                self.offsetMenu = UIScreen.main.bounds.height
            }
        }
    
} label: {
    HStack(spacing: 32) {
        
        Image(systemName: "info.square")
            .font(.title2)
            .frame(width: 26)
        
        Text("privacy_policy")
        
    }
    .frame(minWidth: 0, maxWidth: .infinity, alignment: .leading)
}
