Chocobo 0.0.4

Backbon-ify your iOS models and make it extremely easy to communicate with a RESTful API. Provides an easy API to connect, communicate and return success/failure events.

Installation

There's one other step that you will need to do in order to get it working. Add a file to your project and call it 'Environment.plist'. Inside of there you will need to specify your different API environments you want to use.

Pedro

Now finally add a 'Configuration' parameter to your app's plist.

# support/appName.plist

Configuration (String) 'dev(or whatever you named your environment you want to use)'

Usage

Chocobo allows you to easily create async models/collections in your iOS app to communicate easily with a RESTful API.

Models

Extend your model from the Model object and specify all the attributes using properties.

@interface User : Model

@property (nonatomic, copy) NSNumber *userId;
@property (nonatomic, copy) NSString *firstName;
@property (nonatomic, copy) NSString *lastName;
@property (nonatomic, copy) NSString *email;

@end

Next you will need to override the models method 'updateModelWithJson:'

-(void) updateModelWithJson:(NSDictionary *)json
{
    NSDictionary *attributes = [json valueForKey:@"user"];
    self.userId = [attributes valueForKey:@"id"];
    self.firstName = [attributes valueForKey:@"first_name"];
    self.lastName = [attributes valueForKey:@"last_name"];
    self.email = [attributes valueForKey:@"email"];
}

Now you can call:

[self fetchFromEndpoint:@"login.json" withParams:parameters onSuccess:^(id responseObject) {

        NSLog(@"Do Something with your response object here");

    } onFailure:^(NSError *error)  {

        NSLog(@"Do something with the error");

    }];

Collections

Collections will extend off the Collection object.

#import "Collection.h"

@interface Users : Collection

@end

Your collection will then need to overide 2 functions

-(id)model
{
    return @"User";
}

-(NSString *)collectionEndpoint
{
    return @"users.json";
}

This will allow the collection to automatically grab all the models from the collection endpoint and set them in the models array.

Accessing the models in a collection are easy. Just use the models accessor.

[[collection models] objectAtIndex: 0];

Has Many Relationships

Setting up a has many relationship in your model is easy. Set up an NSMutableArray as a property on the model of the model type that the relationship is set.

# models/user.h

@property (nonatomic, retain) NSMutableArray *accounts;

Synthesize and set up the relationship in a loop inside your updateModelWithJson: function

# models/user.m

@synthesize wells = _wells;

-(void) updateModelWithJson:(NSDictionary *)json
{
    for (NSDictionary* key in [json valueForKey:@"accounts"]) {
        Account *accountModel = [[Account alloc] init];
        [accountModel updateModelWithJson:key];

        [self.accounts addObject:account];
    }
}

Has One Relationships

To setup a has one relationship on your models, set up a property on your model of the type you would like to set it up with.

# models/user.h

#import 'Account.h'

@property (nonatomic, retain) Account *account;

And then in updateModelWithJson:

# models/user.m

-(void) updateModelWithJson:(NSDictionary *)json
{
    Account *account = [[Account alloc] init];
    [account updateModelWithJson: [json valueForKey:@"account"]];
    self.account = account;
}
