Missing initializer compatible to InterfaceBuilder #2

Open

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
