  NavigationView {
            VStack{
                Spacer()
                logo()
                Spacer()
                Text("电话号码")
                    .frame(maxWidth: .infinity, alignment: .leading)
                    .padding(.bottom, 10)
                
                HStack{
                    CountryPicker(selectedCountry: $selectedCountry)
                    
                    TextField("Phones Number", text: $phoneNumber)
                        .keyboardType(.numberPad)
                        .textFieldStyle(RoundedBorderTextFieldStyle())
                }
                .padding(.bottom, 14)
                .frame(maxWidth: .infinity, alignment: .leading)

                        .bold()
                }
                .buttonStyle(PlainButtonStyle())
                .padding(.top,36)

            .navigationTitle("")
            .navigationBarItems(
                trailing:
                    NavigationLink(destination: Text("Second View")) {
                        Text("遇到问题")
                    }
                
                // Vstack Line
            )
            .padding()
            .frame(maxWidth: .infinity)
            
            // Navigation Stack
        }
        .padding(.vertical, 5)

Hi, I'm new to swift ui, I tried to make the

                    Text("登陆")
                        .foregroundColor(.white)
                        .padding()
                        .background(Color.black)
                        .cornerRadius(10)
                        .frame(maxWidth: .infinity, alignment: .center)
                        .bold()
                }

this navigationLink expand the whole width of the Vstack, so I tried to use .frame(maxWidth: infinity) on it but it still doesn't work

Can any one helps me on this problem, Thank you

Hi @Ting_Qu ,

The order of your modifiers is the issue here. Instead of:

.background(Color.black)
.cornerRadius(10)
.frame(maxWidth: .infinity, alignment: .center)

You need

.frame(maxWidth: .infinity, alignment: .center)
.background(Color.black)
.cornerRadius(10)

Right now, the background color is being applied to the text, which has a very small width. You then set the frame, but the background color won't change based on that since it's already been applied. Set the frame first, then the background color.
