delegate.m

// The Detector delegate should implement this method:

- (void)glyphDetected:(WTMGlyph *)glyph withScore:(float)score {
    // Go forth and do awesome things
}

initialization.m

#import "WTMGlyphDetector.h"

// MyDetectingThing.h
@interface SpellInputLayer : CCLayer <WTMGlyphDelegate> {
    WTMGlyphDetector *glyphDetector;
}

// MyDetectingThing.m

// An example method in an object that initializes the
// gesture detector
- (void)initGestureDetector {
  // Initialize
  glyphDetector = [WTMGlyphDetector detector];

  // Assign the detection delegate
  glyphDetector.delegate = self;

  // Add initial glyph templates from JSON files
  // Rinse and repeat for each of the gestures you want to detect
  NSData *jsonData = [NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"D" ofType:@"json"]];
  [self addGlyphFromJSON:jsonData name:@"D"];
}

There is a small mistake here: [self addGlyphFromJSON:jsonData name:@"D"];
It should be
[glyphDetector addGlyphFromJSON:jsonData name:@"D"];
