CocoaFn

Collection extensions for Objective-C. (ARC environment)

Current progress

• NSArray
• NSDictionary
• NSSet

Common tasks

This extension provides following tasks for supported collection classes.

• each
• map
• reduce
• select
• reject

Requirements

• Ruby
  • For 'CocoaPods'
• Bundler
  • RubyGems

Dependencies

• Test
  • Expecta (~> 1.0)

How to try

Use in project with Cocoapods

Add following one line to your Podfile .

pod 'CocoaFn', :git => 'https://github.com/kmhjs/CocoaFn.git', :branch => 'develop'

Run project for test / development

1. bundle install --path=./bundle/install
2. bundle exec pod install

After these steps, you can try with CocoaFn.xcworkspace .

Example

Each

[self.stringTestSet each:^(NSString *element) {
  [result addObject:element];
}];

self.stringTestSet.each(^(NSString *element) {
  [result addObject:element];
});

Map

[self.stringTestSet map:^id(id element) {
  return [NSString stringWithFormat:@"element = %@", (NSString *)element];
}];

self.stringTestSet.map(^id(id element) {
  return [NSString stringWithFormat:@"element = %@", (NSString *)element];
});

Reduce

[self.numberTestSet reduce:@(0) fn:^id(NSNumber *accumlator, NSNumber *element) {
  return @([accumlator floatValue] + [element floatValue]);
}];

self.numberTestSet.reduce(@(0), ^id(NSNumber * accumlator, id element) {
  return @([accumlator floatValue] + [element floatValue]);
});

Select

[self.numberTestSet select:^BOOL(NSNumber *element) {
  return [element floatValue] > 3;
}];

self.numberTestSet.select(^BOOL(NSNumber *element) {
  return [element floatValue] > 3;
});

Reject

[self.numberTestSet reject:^BOOL(NSNumber *element) {
  return [element floatValue] <= 3;
}];

self.numberTestSet.reject(^BOOL(NSNumber *element) {
  return [element floatValue] <= 3;
});

Combination

[[self.numberTestSet map:^id _Nonnull(NSNumber * _Nonnull element) {
  return @([element floatValue] * 10);

}] select:^BOOL(id  _Nonnull element) {
  return [element floatValue] > 30;

}];

self.numberTestSet.map(^id _Nonnull(NSNumber * _Nonnull element) {
  return @([element floatValue] * 10);

}).select(^BOOL(id  _Nonnull element) {
  return [element floatValue] > 30;

});
