Morse Gesture Recognizer

This library provides a UIGestureRecognizer that recognizes and parses Morse Code tap events.

Basic Usage

@import WSMorseGestureRecognizer;

...

UIView *aView = ...
WSMorseGestureRecognizer *morseGestureRecognizer =
  [[WSMorseGestureRecognizer alloc] initWithTarget:self
                                            action:@selector(morseAction:)];
morseGestureRecognizer.stringToRecognize = @"SOS";
[aView addGestureRecognizer:morseGestureRecognizer];

...

- (void)morseAction:(WSMorseGestureRecognizer *)recognizer {
    if (recognizer.state == UIGestureRecognizerStateRecognized) {
        ...
    }
}

wsmorsegesturerecognizer's Issues

gesture has no timeout

Hello developers,

workflow to reproduce:

embed the gesture in view in a viewcontroller with other gestures enabled (e.g. UIScrollView)
start morse gesture, which is not the expected morse code
start other gesture (e.g. try to scroll the UIScrollView

expected:

other gesture should work

issue:

other gesture doesn't work

analysis:

morse gesture is running forever and catches all events
maybe you should add an optional timeout to your gesture implementation
or you let other gestures work simultanous

best regards, Oliver

Missing initializer compatible to InterfaceBuilder

Hello developers,

workflow to reproduce issue:

add WSMorseGestureRecognizer as "Custom Gesture" to view in storyboard/xib
set delegate, target/action
set reference to your code as outlet
configure gesture in code or in InterfaceBuilder via keyPath (e.g. stringToRecignize, characterParseDelay, wordParseDelay)

expected:

if entered/touched morse code matches with "stringToRecignize", the calback/action should be triggered

issue:

no morse code is recognized, any callback (morsecode, character, word) return empty string, action is never triggered

analysis:

mutable array "currentSequence" is not initialized
although the UIGestureRecognizer is no NSCoder conforming UI class it is used in InterfaceBuilder
you have to implement NSCoder initialiser "-[NSCoder initWithCoder:]" or at least override "-[NSObject init]" where you should setup your properties; at least "currentSequence"

best regards, Oliver
