User Profile

I wanna add a score when the character contacts with the 'coins' and game over when it contacts with the 'enemies'. But it doesn't work. I compiled the ...Category and <SKPhysicsContactDelegate> code in GameScene.h and these:- (instancetype)initWithSize:(CGSize)size { if (self = [super initWithSize:size]) { self.character = [SKSpriteNode spriteNodeWithImageNamed:@"character"]; self.character.position = CGPointMake(100, 100); [self addChild:self.character]; self.physicsWorld.gravity = CGVectorMake(0,0); self.physicsWorld.contactDelegate = self; } return self; }in .m above didMoveToView method. Can I use initWithSize in Xcode 8? And I do use these code in .m:character.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:character.size]; //1 character.physicsBody.dynamic = YES; //2 character.physicsBody.categoryBitMask = characterCategory; //3 character.physicsBody.contactTestBitMask = coinCategory | enemiesCategory;//4 character.physicsBody.collisionBitMask = 0; // 5I use them in "setPhysicsBody:(SKPhysicsBody *)physicsBody" method. And of couse I compiled the didBeginContact method. Did I miss anything? Please help me. Thank you very much.

I am building an iOS app with Google sign-in Facebook sign-in, comment/like system, todo lists, and simple chat system with Swift and Firebase. I am doing open source programming. How much time do I actually need? I used almost 9 months for doing it and haven't finish because of debugging and the storyboard is too slow. Do you all think I took a lot time? Why I take so much time? How can I improve?Please help me, Thanks.

I added search bar to a table view controller programmatically. I use Firebase. But there is no cell since I added search bar. Please see the code:var soemArray = [SomeFile]() var filteredArray = [SomeFile]() var shouldShowSearchResults = false var searchController: UISearchController! var customSearchController: CustomSearchController! override func viewDidLoad() { super.viewDidLoad() configureCustomSearchController() } func getData(){ dataBaseRef.child("text").observe(.value, with: { (snapshot) in var results = [SomeFile]() for user in snapshot.children { let user = SomeFile(snapshot: user as! DataSnapshot) if user.name != user.url { results.append(user) } } someArray = results.sorted(by: { (u1, u2) -> Bool in u1.name < u2.name }) self.tutsArray = results.sorted(by: { (u1, u2) -> Bool in u1.url! < u2.url! }) self.tableView.reloadData() }) { (error) in print(error.localizedDescription) } } override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { / if shouldShowSearchResults { return filteredArray.count } else { return tutsArray.count } } override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { let cell = tableView.dequeueReusableCell(withIdentifier: "someCell", for: indexPath) as! ArtTutsTableViewCell cell.name.text = someArray[indexPath.row].tutName / if shouldShowSearchResults { cell.name.text = filteredArray[indexPath.row].name } else { cell.name.text = someArray[indexPath.row].name } return cell } func configureSearchController() { / searchController = UISearchController(searchResultsController: nil) searchController.searchResultsUpdater = self as? UISearchResultsUpdating searchController.dimsBackgroundDuringPresentation = false searchController.searchBar.placeholder = "Search here..." searchController.searchBar.delegate = self as? UISearchBarDelegate searchController.searchBar.sizeToFit() tableView.tableHeaderView = searchController.searchBar } configureCustomSearchController() { customSearchController = CustomSearchController(searchResultsController: self, searchBarFrame: CGRect(x:0.0, y:0.0, width: tableView.frame.size.width, height:50.0), searchBarFont: UIFont(name: "Futura", size: 16.0)!, searchBarTextColor: UIColor.orange, searchBarTintColor: UIColor.black) / tableView.tableHeaderView = customSearchController.customSearchBar func searchBarTextDidBeginEditing(searchBar: UISearchBar) { shouldShowSearchResults = true tableView.reloadData() } func searchBarCancelButtonClicked(searchBar: UISearchBar) { shouldShowSearchResults = false tableView.reloadData() } func searchBarSearchButtonClicked(searchBar: UISearchBar) { if !shouldShowSearchResults { shouldShowSearchResults = true tableView.reloadData() } searchController.searchBar.resignFirstResponder() } func updateSearchResultsForSearchController(searchController: UISearchController) { guard let searchString = searchController.searchBar.text else { return } / self.filteredArray = self.tutsArray.filter({ (tutArray: Tutorials) -> Bool in let text: NSString = tutArray.tutName as! NSString return (text.range(of: searchString, options: NSString.CompareOptions.caseInsensitive).location) != NSNotFound }) self.tableView.reloadData() } func didStartSearching() { shouldShowSearchResults = true tableView.reloadData() } func didTapOnSearchButton() { if !shouldShowSearchResults { shouldShowSearchResults = true tableView.reloadData() } } func didTapOnCancelButton() { shouldShowSearchResults = false tableView.reloadData() } func didChangeSearchText(searchText: String) { self.filteredArray = self.tutsArray.filter({ (tutArray: Tutorials) -> Bool in let text: NSString = tutArray.tutName as NSString return (text.range(of: searchText, options: NSString.CompareOptions.caseInsensitive).location) != NSNotFound }) tableView.reloadData() }

cell.imageView!.image = UIImage(data: data) cell.imageView?.layer.borderWidth=1.0 cell.imageView?.layer.masksToBounds = true cell.imageView?.layer.borderColor = UIColor.white.cgColor cell.imageView?.layer.cornerRadius = (cell.imageView?.frame.size.height)!/2 cell.imageView?.clipsToBounds = trueI added this code to make the image in the cell round. But it is not round. Can anyone tell me why? And help me? Thanks

I have Google, Facebook and email sign in. I have made a user profile which shows the users' usernames, countries, full names, biographies and images. The email sign in is successful, I can store all these users' infos in the create account page to Firebase Database. But for Google and Facebook, I can only store some of the infos. I am now searching from your advices. How can I show the User Profile? If I don't show the User Profile for the Google and Facebook users, will it affect their experiences? I am thinking of putting no info in the biographies, countries etc in User Profile, and ask them to create one and I will save those info to the database. The next time, when they come in, they will lose those datas, right? Wish to get your great advices. Thanks

This is my code:var art: Int = 0 @IBAction func art(_ sender: Any) { art += 1 tutText = "artTut" if art == 1{ print(art) let storyBoard: UIStoryboard = UIStoryboard(name: "Art", bundle: nil) let newViewController = storyBoard.instantiateViewController(withIdentifier: "UITabBarController") as! NewViewController self.present(newViewController, animated: true, completion: nil) } }The log printed '1'. But when I proceed to NewViewController, the log printed '0' See the code in NewViewController.:let main = PreviousViewController() print(main.art)Do you have solution so that it printed '1' in NewViewController

My app ran successfully but I got 'This app could not be installed'. I tried the solutions on the internet but no help. Then I realize I lost my Podfile and cannot run 'pod update' in Terminal. Do you think the missing podfile is the cause of the app cannot being installed to Simulator? How to fix the missing podfile? I am thinking of running 'sudo gem install cocoapods' to install the podfile. But will it cause anything to my project. I will be appreciated if someone can give me the solutions. Thanks.
