App academy - Parse
- 2. Parse mobile backend as a service
- 10. Alle vrijheid vs Tijd besparen en andermans expertise gebruiken
- 13. Wat biedt Parse? Backend as a service
- 14. Parse Core Meest interessante van de drie
- 15. Data opslaan in de cloud Tekst Locaties Bestanden (foto’s bijv) Data ophalen dmv queries
- 18. App sociaal maken Inloggen met Facebook en Twitter Inloggen/Registreren met emailadres
- 19. Lokaal data bewaren Ook toegang tot alle data wanneer er geen internetverbinding is. Dit is bijzonder lastig
- 20. Eigen website draaien Niet enkel statisch, maar met toegang tot alle data die verzamelt is met de app
- 22. Background jobs Eenvoudig langdurige processen draaien zonder dat de app er op hoeft te wachten Bijv foto’s resizen, emails versturen
- 23. Parse Dashboard Eenvoudig toegang tot alle data via het web
- 24. Parse Push Push Notificaties waren nog nooit zo simpel
- 26. Eenvoudig zelf berichten versturen Via de parse composer
- 27. Of vanuit de app of ahv bepaalde acties
- 29. Parse Analytics Meten is weten
- 31. Meet het gebruik van je app Installaties Actieve gebruikers Retention
- 33. Meet het gebruik ahv eigen events Met 1 regel zelf toevoegen aan je app Bijv. wanneer iemand iets shared, een foto liked, voor de eerste keer een actie uitvoert, etc
- 34. Wat kost Parse? Het is niet gratis, maar….
- 36. Gratis tot: 30 requests per seconde 20GB file storage 1 miljoen devices voor push Analytics altijd gratis
- 38. Hoe werkt het dan? Teveel om uit te leggen, maar een aantal voorbeelden
- 40. PFObject *keynote = [PFObject objectWithClassName:@"Keynote"]; keynote[@"name"] = @“Parse”; keynote[@"presenterName"] = @“Timan Rebel"; keynote[@"boring"] = @NO; [keynote saveInBackground];
- 42. PFQuery *query = [PFQuery queryWithClassName:@"Keynote"]; [query getObjectInBackgroundWithId:@"xWMyZ4YEGZ" block:^(PFObject *keynote, NSError *error) { // Do something with the returned PFObject in the keynote variable. if (!error) { // The get request succeeded. Log the score NSLog(@"The presenter was: %@", keynote[@"presenterName"]); } else { // Log details of our failure NSLog(@"Error: %@ %@", error, [error userInfo]); }}];
- 43. // First set up a callback. - (void)getCallback:(PFObject *)keynote error:(NSError *)error { if (!error) { // The get request succeeded. Log the score NSLog(@"The presenter was: %@", keynote[@"presenterName"]); } else { // Log details of our failure NSLog(@"Error: %@ %@", error, [error userInfo]); } } // Then, inside another method elsewhere in your code...
