Parse.com presentation

Parse.com presentation I gave to an internal team at R/GA.

Transcript

1. Parse.com Mobile app platform By John Tubert
2. Disclaimer I am NOT an iOS developer, nor an expert in the parse.com platform.
3. Why parse.com? • Free (to start) • No server needed • Easy to use • Multi-platform
4. How to get started 1. Create free account 2. Download SDK or blank xcode project 3. Start coding
5. How to really get started 1. Add framework to project 2. Add import statement to prefix file a. #import <Parse/Parse.h> 3. Initialize parse on delegate file a. [Parse setApplicationId:@"" clientKey:@""]; 4. Add code to read or write to parse.com

7. Write PFObject *addressObject = [PFObject objectWithClassName:@"Addresses"]; [addressObject setObject:@"John Tubert" forKey:@"name"]; [addressObject setObject:@"350 west 39th Street" forKey:@"Address"]; [addressObject setObject:@"New York" forKey:@"City"]; [addressObject setObject:@"NY" forKey:@"State"]; [addressObject setObject:@"10018" forKey:@"Zip"]; [addressObject save];
8. Count PFQuery *queryPhotoCount = [PFQuery queryWithClassName:@"Photo"]; [queryPhotoCount whereKey:kPAPPhotoUserKey equalTo:[PFUser currentUser]]; [queryPhotoCount setCachePolicy:kPFCachePolicyCacheThenNetwork]; [queryPhotoCount countObjectsInBackgroundWithBlock:^(int number, NSError *error) { if (!error) { NSLog(@"count: %i",number); } }];
9. Read PFQuery *query = [PFQuery queryWithClassName:@"Addresses"]; [query setCachePolicy:kPFCachePolicyCacheThenNetwork]; [query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) { if (error) { NSLog(@"error %@",error); }else{ NSLog(@"objects %@",objects); } }];
10. Read (with constraints) PFQuery *query = [PFQuery queryWithClassName:@"Addresses"]; [query whereKey:@"name" containsString:@"John"]; [query setCachePolicy:kPFCachePolicyCacheThenNetwork]; [query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) { if (error) { NSLog(@"error %@",error); }else{ NSLog(@"objects %@",objects); } }];
11. More constraints Basic Constraints - (void)includeKey:(NSString *)key; - (void)whereKeyExists:(NSString *)key; - (void)whereKeyDoesNotExist:(NSString *)key; - (void)whereKey:(NSString *)key equalTo:(id)object; - (void)whereKey:(NSString *)key lessThan:(id)object; - (void)whereKey:(NSString *)key lessThanOrEqualTo:(id)object; - (void)whereKey:(NSString *)key greaterThan:(id)object; - (void)whereKey:(NSString *)key greaterThanOrEqualTo:(id)object; - (void)whereKey:(NSString *)key notEqualTo:(id)object; - (void)whereKey:(NSString *)key containedIn:(NSArray *)array; - (void)whereKey:(NSString *)key notContainedIn:(NSArray *)array; Location Constraints - (void)whereKey:(NSString *)key nearGeoPoint:(PFGeoPoint *)geopoint; - (void)whereKey:(NSString *)key nearGeoPoint:(PFGeoPoint *)geopoint withinMiles:(double)maxDistance; - (void)whereKey:(NSString *)key nearGeoPoint:(PFGeoPoint *)geopoint withinKilometers:(double)maxDistance; - (void)whereKey:(NSString *)key nearGeoPoint:(PFGeoPoint *)geopoint withinRadians:(double)maxDistance; - (void)whereKey:(NSString *)key withinGeoBoxFromSouthwest:(PFGeoPoint *)southwest toNortheast:(PFGeoPoint *) northeast; String Constraints - (void)whereKey:(NSString *)key matchesRegex:(NSString *)regex; - (void)whereKey:(NSString *)key matchesRegex:(NSString *)regex modifiers:(NSString *)modifiers; - (void)whereKey:(NSString *)key containsString:(NSString *)substring; - (void)whereKey:(NSString *)key hasPrefix:(NSString *)prefix; - (void)whereKey:(NSString *)key hasSuffix:(NSString *)suffix;
12. Saving photos PFObject *photo = [PFObject objectWithClassName:kPAPPhotoClassKey]; [photo setObject:[PFUser currentUser] forKey:kPAPPhotoUserKey]; [photo setObject:self.photoFile forKey:kPAPPhotoPictureKey]; [photo setObject:self.thumbnailFile forKey:kPAPPhotoThumbnailKey]; [photo save];
13. DEMO Show ArchUp demo
14. Demo: using JS API http://jtubert.com/sketchit/
15. Server side methods (AKA: cloud code) Parse.Cloud.define("hello", function(request, response) { response.success("Hello Parse world!"); });
16. Getting started: Cloud code Install the command line tool: curl -s https://www.parse.com/downloads/cloud_code/installer.sh | sudo /bin/bash Create new project: $ parse new MyCloudCode Write functions: Parse.Cloud.define("hello", function(request, response) { response.success("Hello world!"); }); Deploy code: $ parse deploy Call methods from app: [PFCloud callFunctionInBackground:@"hello" withParameters:@{} block:^(NSString *result, NSError *error) { if (!error) { // result is @"Hello world!" NSLog(@"%@",result); } }];
