Software development is the process of conceiving, specifying, designing, programming, documenting, testing, and bug fixing involved in creating and maintaining applications, frameworks, or other software components. Software development involves writing and maintaining the source code, but in a broader sense, it includes all processes from the conception of the desired software through to the final manifestation of the software, typically in a planned and structured process. Software development also includes research, new development, prototyping, modification, reuse, re-engineering, maintenance, or any other activities that result in software products.
I wanted to open a Facebook Group page in the Facebook app on my iPhone but I was getting that error since I did not have any LSApplicationQueriesSchemes in my Info.plist file.
This is the code
let fbPage = "fb://profile/" + FB_GROUP_ID // Your Facebook group id e.g 8794808798015
let fbURL = URL(string:fbPage)
let canOpenURL = UIApplication.shared.canOpenURL(fbURL!)
if (canOpenURL) {
UIApplication.shared.open(fbURL!, completionHandler: nil)
}
After adding ‘fb’ in my scheme it solves the issue.
I was having this issue when setting a new rootViewController from loginViewController , which was a rootViewController in the storyboard before the transition.
I was not sure what was the problem. Since this works perfect on iOS 13 if I don’t use the [UIView transitionFromView] but I wanted to keep the animation effect, it looked good.
I decided to made a simple trick, by using a dummy view. Which solved this problem.
instead of using homeViewController.view we use dummy view for the animation and white as its background, otherwise you will see black background between transitions.
I was trying to build a simple app in iOS + SwiftUI with multiple views that uses NavigationView and NavigationLink.
This app is very simple and uses a model to navigate between destinations. Enum ViewType tracks all the destinations. If you want to have another view, View4, just add a new case in ViewType enum.
struct Menu: Identifiable {
var id = UUID()
var name: String
var image: String
var destination: ViewType
}
enum ViewType {
case home
case view1
case view2
}
Our all views must have a property with menu type
struct HomeView: View {
var menu: Menu
var body: some View {
Text("Home View")
}
}
Our MasterView which is the main view in root ContentView. Also, we added HomeView as our default view here.
var body: some View {
NavigationView {
MasterView()
.navigationBarTitle(
Text("Navigation Demo")
)
HomeView(menu: Menu(name:"Home", image:"image", destination: .home))
}.navigationViewStyle(DefaultNavigationViewStyle())
}
In our MasterView we have an array of Menu with title and destination view case, which populated in a list view.
let view1 = Menu(name:"Home", image:"image", destination: .home)
let view2 = Menu(name:"View 1", image:"image", destination: .view1)
let view3 = Menu(name:"View 3", image:"image", destination: .view2)
var body: some View {
let menus: [Menu] = [view1, view2, view3]
return List {
ForEach(menus) { menu in
self.destinationView(menu: menu)
}
}
}
function destinationView return a NavigationLink based on what item you choose on the list and take the user to the expected view.
