Remove all the nulls from array
| - ("Please use -firstObject instead") DEPRECATED_MSG_ATTRIBUTE |
The first item in the array, or nil.
| - ("Please use -lastObject instead") DEPRECATED_MSG_ATTRIBUTE |
The last item in the array, or nil.
| - (id) detect: | (BOOL(^)(id object)) | block |
Iterate through current array returning the first element meeting a criteria.
| block | A block that returns YES/NO |
| - (void) each: | (void(^)(id object)) | block |
A simpler alias for enumerateObjectsUsingBlock
| block | A block with the object in its arguments. |
| - (void) each: | (void(^)(id object)) | block | |
| options: | (NSEnumerationOptions) | options | |
A simpler alias for enumerateObjectsWithOptions:usingBlock:
| block | A block with the object in its arguments. |
| options | Enumerating options. |
| - (void) eachWithIndex: | (void(^)(id object, NSUInteger index)) | block |
A simpler alias for enumerateObjectsUsingBlock which also passes in an index
| block | A block with the object in its arguments. |
| - (void) eachWithIndex: | (void(^)(id object, NSUInteger index)) | block | |
| options: | (NSEnumerationOptions) | options | |
A simpler alias for enumerateObjectsWithOptions:usingBlock: which also passes in an index
| block | A block with the object in its arguments. |
| options | Enumerating options. |
| - (id) find: | (BOOL(^)(id object)) | block |
Alias for detect. Iterate through current array returning the first element meeting a criteria.
| block | A block that returns YES/NO |
| - (NSArray *) flatten |
Recurse through self checking for NSArrays and extract all elements into one single array
| - (BOOL) includes: | (id) | object |
An alias for containsObject
| object | An object that the array may or may not contain. |
| - (NSArray *) intersectionWithArray: | (NSArray *) | array |
Return all the objects that are in both self and array. Alias for Ruby's & operator
| - (NSString *) join |
Alias for componentsJoinedByString with a default of no seperator
| - (NSString *) join: | (NSString *) | separator |
Alias for componentsJoinedByString
seperator string | - (NSArray *) map: | (id(^)(id object)) | block |
Iterate through the current array running the block on each object and returning an array of the changed objects.
| block | A block that passes in each object and returns a modified object |
| - (id) objectForKeyedSubscript: | (id< NSCopying >) | key |
Allow subscripting to fetch elements within the specified range
| key | An NSString or NSValue wrapping an NSRange. It's intended to behave like Ruby's array range accessors. Given array of 10 elements, e.g. [1, 2, 3, 4, 5, 6, 7, 8, 9, 10], you can perform these operations: array[@"1..3"] will give you [2, 3, 4] array[@"1...3"] will give you [2, 3] (last value excluded) array[@"1,3"] implies NSRange(location: 1, length: 3), and gives you [2, 3, 4] |
| - (id) reduce: | (id(^)(id accumulator, id object)) | block |
Return a single value from an array by iterating through the elements and transforming a running total.
| - (id) reduce: | (id) | initial | |
| withBlock: | (id(^)(id accumulator, id object)) | block | |
Same as -reduce, with initial value provided by yourself
| - (NSArray *) reject: | (BOOL(^)(id object)) | block |
Iterate through current array asking whether to remove each element.
| block | A block that returns YES/NO for whether the object should be removed |
| - (NSArray *) relativeComplement: | (NSArray *) | array |
Return all the objects in self that are not in array. Alias for Ruby's - operator
array | - (NSArray *) reverse |
Alias for reverseObjectEnumerator.allObjects
Returns a reversed array
| - (id) sample |
A random element in the array, or nil.
| - (NSArray *) select: | (BOOL(^)(id object)) | block |
Iterate through current array asking whether to keep each element.
| block | A block that returns YES/NO for whether the object should stay |
| - (NSArray *) sort |
Run the default comparator on each object in the array
| - (NSArray *) sortBy: | (NSString *) | key |
Sorts the array using the the default comparator on the given key
| - (NSArray *) symmetricDifference: | (NSArray *) | array |
Return all the objects that are unique to each array individually Alias for Ruby's ^ operator. Equivalent of a - b | b - a
| - (NSArray *) take: | (NSUInteger) | numberOfElements |
Take the first numberOfElements out of the array, or the maximum amount of elements if it is less.
| numberOfElements | Number of elements to take from array |
| - (NSArray *) takeWhile: | (BOOL(^)(id object)) | block |
Passes elements to the block until the block returns NO, then stops iterating and returns an array of all prior elements.
| block | A block that returns YES/NO |
| - (NSArray *) unionWithArray: | (NSArray *) | array |
Return all the objects that in both self and array combined. Alias for Ruby's | operator
| - (NSArray *) unique |
Produces a duplicate-free version of the array
