CollectionUtils-AFNetworking-1.3 1.0.1

You want to add pod 'CollectionUtils-AFNetworking-1.3', '~> 1.0' similar to the following to your Podfile:

target 'MyApp' do
  pod 'CollectionUtils-AFNetworking-1.3', '~> 1.0'
end

Then run a pod install inside your terminal, or from CocoaPods.app.

Alternatively to give it a test run, run the command:

pod try CollectionUtils-AFNetworking-1.3

CollectionUtils

Useful utilities for Objective-C collection classes.

CollectionUtils/Compact

Subclasses of NSArray and NSDictionary to recursively remove all NSNull values automatically with little performance penalty.
It is useful for JSON returned from web services.

Usage

Remove NSNull values from an array

NSArray *array = @[@"0", @"1", [NSNull null], @"2", [NSNull null], @"3"];
NSArray *compactArray = [array cu_compactArray];
//=> ["0", "1", "2", "3"]

Remove NSNull values from a dictionary

NSDictionary *dictionary = @{@"one": @"1",
                             @"null": [NSNull null],
                             @"two": @"2",
                             @"three": @"3"};
NSDictionary *compactDictionary = [dictionary cu_compactDictionary];
 //=> {"one": "1", "two": "2", "three": "3"}

Recursively remove all NSNull values by default

NSArray *array = @[@"0",
                   @"1",
                   [NSNull null],
                   @"2",
                   @{@"one": @"1",
                     @"null": [NSNull null],
                     @"two": @"2",
                     @"three": @"3"},
                   @"4"];
NSMutableArray *compactArray = [array cu_compactArray];
//=> ["0", "1", "2", {"one": "1", "two": "2", "three": "3"}, "4"]

Remove all NSNull values from JSON returned from web services.

id object = [NSJSONSerialization JSONObjectWithData:data options:opt error:error];
id result =  [object cu_compactJSONObject];

CUJSONSerialization is a convienience class to remove all NSNull values from JSON data

id result = [CUJSONSerialization JSONObjectWithData:data options:kNilOptions error:nil];

AFNetworking Additions

CUJSONResponseSerializer (for AFNetworking 2.x)

Install

pod "CollectionUtils-AFNetworking"

Usage

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.responseSerializer = [CUJSONResponseSerializer serializer];

[manager GET:@"http://example.com/resources.json" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"JSON: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

CUJSONRequestOperation (for AFNetworking 1.x)

Install

pod "CollectionUtils-AFNetworking-1.3"

Usage

NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://example.com/resources.json"]];
CUJSONRequestOperation *operation = [CUJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
    NSLog(@"JSON: %@", JSON);
} failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
    NSLog(@"Error: %@", error);
}];
[operation start];

AFHTTPClient *client = [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:@"http://example.com/"]];
[client registerHTTPOperationClass:[CUJSONRequestOperation class]];
[client setDefaultHeader:@"Accept" value:@"application/json"];

[client getPath:@"resouce.json" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"JSON: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

Little performance penalty

How it works

CUCompactArray and CUCompactDictionary just wrap the original array/dictionary to behave as if do not have NSNull values.

To remove NSNull values for the nested collection is delayed until the nested array/dictionary is really accessed.
It is performed only for one level at a time.

Requirements

iOS 4.3 or later
OS X 10.6 or later

Installation

If you want to use AFNetworking additions, add the following line:

pod "CollectionUtils-AFNetworking"

if you use older version AFNetworking,

pod "CollectionUtils-AFNetworking-1.3"
