A category that adds an instragram-like hashtag choosing/listing capability to the UITextView.

Installation

Alternatively you can drop the "Classes" folder into your project that should have the ReactiveCocoa library installed

Import the category:

#import <AVTagTextView/UITextView+AVTagTextView.h>

Usage

Assign the hashTagsDelegate property to the desired delegate and implement the tagsForQuery method:

self.textView.hashTagsDelegate = self;
//...

/**
 * As soon as the user enters some symbols after the last '#' sign, this method gets called.
 * Entered symbols are contained in the query string. It is your responsibility to provide 
 * the text view with the list of the corresponding hashtags as an array of strings:
 */
- (NSArray *)tagsForQuery:(NSString *)query{
    //Provide the list of the tag, you wish to display to the user:

    //For example, return the tags, which start with the query string, from the predefined array:
    NSPredicate *bPredicate =
    [NSPredicate predicateWithFormat:@"SELF beginswith[c] %@", query];
    NSArray *array = [self.tagsArray filteredArrayUsingPredicate:bPredicate];

    return array;
}

Hashtags, contained in the UITextView, can be accessed through its hashTags property:

self.textView.hashTags //returns an array of strings, corresponding to the hash tags, found in the UITextView's text

The default UITableViewController that displays the tags can be replaced with your custom UITableViewController implementation that has to conform to the AVTagTableViewProtocol. See the exemplary AVCustomTagTableViewController class.

Example

To run the example project; clone the repo, and run pod install from the Project directory first.

Requirements

  • ReactiveCocoa. The category strongly relies on the capabilities of ReactiveCocoa library to react on the user's input and to properly handle the keyboard's hiding/showing notifications.
  • iOS 6.1 or greater

Tests

The project includes a Kiwi spec that can be found in the Tests folder

TODO

  1. Remove ReactiveCocoa as a dependency.
