8. Storing Data
Parse Data
PFObject is like an NSMutableDictionary in the cloud
PFObject *armor = [PFObject objectWithClassName:@“Armor”];
[armor setObject:@“Shield” forKey:@“name”];
armor[@“price”] = @50;
[armor saveInBackground];

9. Storing Data
Parse Data
!
Armor
*shield
=
[Armor
object]
shield.name
=
@“shield”;
shield.cost
=
50;
Can also use like a class:

10. Fetching Data
Parse Data
PFQuery
*query
=
[Armor
query];
[query
whereKey:@“name”
equalTo:@“shield”];
[query
whereKey:@“cost”
lessThan:@50];
[query
findObjectsInBackgroundWithBlock:
^(NSArray
*objects,
NSError
*error)
{
/*
...
*/
}];

11. Signing Up
Parse Social
PFUser
*user
=
[PFUser
user];
user.username
=
@“inlined”;
user.password
=
@“YC
H4cks”;
[user
signUpInBackgroundWithBlock:
^(BOOL
success,
NSError
*error)
{
/*
...
*/
}];

12. Social Integration
Parse Social
[PFFacebookUtils
logInWithPermissions:nil
block:
^(PFUser
*user,
NSError
*error)
{
/*
...
*/
}];

13. UI Controls
Parse Social
Replace login code with built-in view
controllers
Fully customizable

14. Parse Cloud Code
For when server-side code is needed or easier
Trusted execution environment
Data pipeline integration
Third party integration
Hosting static and dynamic resources

15. Parse Cloud Code
Parse.Cloud.afterSave(
“Message”,
function(request)
{
Parse.Push.send({
channel:
request.object.get(“room”),
data:
{
alert:
request.object.get(“message”)
}
});
});

16. Parse Push

17. Registering
Parse Push
[PFPush
storeDeviceToken:deviceToken];
[PFPush
subscribeToChannelInBackground:@“hack”];

18. Sending
Parse Push
PFPush
*push
=
[PFPush
push];
push.channel
=
@“hack”;
push.message
=
@“Move
fast
and
build
things”;
[push
sendInBackgroundWithBlock:
^(BOOL
succeeded,
NSError
*error)
{
/*

Parse Social
//
Automatically

all
objects

create
but
//
allow
everyone

read
them.
PFACL
*acl
=
[PFACL
ACL];
[acl
setPublicReadAccess:YES];
[PFACL
setDefaultACL:acl
withAccessForCurrentUser:YES]

27. Logging In
Parse Social
PFUser
*user
=
[PFUser
logInWithUsername:@“inlined”
password:@“YC
H4cks”];
//
From
now
on:
PFUser
*user
=
[PFUser
currentUser];

28. Storing Data

Can also use like a class:
@interface
Armor
:
PFObject<PFSubclassing>
//
Properties
are
synthesized
with
@dynamic
@property
(nonatomic)
