#import <UIKit/UIKit.h>

@interface UIGestureRecognizer (DBTrackingAdditions)

@property (nonatomic, readonly, getter=isTracking) BOOL tracking;

@end

#import "UIGestureRecognizer+DBTrackingAdditions.h"

@implementation UIGestureRecognizer (DBTrackingAdditions)

- (BOOL)isTracking
{
    return (self.state == UIGestureRecognizerStateBegan || self.state == UIGestureRecognizerStateChanged);
}
