    <p>I am trying to implement game control that will be changes direction of unit movement. So if i do right swipe it turns to the right, if i do down swipe it turns to the down direction etc.</p> <p>It's cocos2d game, and i'am using <code>CCNode+SFGestureRecognizers</code> with <code>UISwipeGestureRecognizer</code>.</p> <p>At now I have next implementation for it</p> <pre><code>UISwipeGestureRecognizer *rightSwipeGestureRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleRightSwipe:)]; [self addGestureRecognizer:rightSwipeGestureRecognizer]; rightSwipeGestureRecognizer.direction = UISwipeGestureRecognizerDirectionRight; rightSwipeGestureRecognizer.delegate = self; [rightSwipeGestureRecognizer release]; UISwipeGestureRecognizer *upSwipeGestureRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleUpSwipe:)]; [self addGestureRecognizer:upSwipeGestureRecognizer]; upSwipeGestureRecognizer.direction = UISwipeGestureRecognizerDirectionUp; upSwipeGestureRecognizer.delegate = self; [upSwipeGestureRecognizer release]; UISwipeGestureRecognizer *leftSwipeGestureRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleLeftSwipe:)]; [self addGestureRecognizer:leftSwipeGestureRecognizer]; leftSwipeGestureRecognizer.direction = UISwipeGestureRecognizerDirectionLeft; leftSwipeGestureRecognizer.delegate = self; [leftSwipeGestureRecognizer release]; UISwipeGestureRecognizer *downSwipeGestureRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleDownSwipe:)]; [self addGestureRecognizer:downSwipeGestureRecognizer]; downSwipeGestureRecognizer.direction = UISwipeGestureRecognizerDirectionDown; downSwipeGestureRecognizer.delegate = self; [downSwipeGestureRecognizer release]; </code></pre> <p>but the problem is that for to recognize the following gesture you need to lift your finger from the screen. if you do not lift a finger after the first swipe, it will recognize only the first swipe.</p> <p><strong>at now:</strong></p> <p><img src="https://i.stack.imgur.com/1MUUx.png" alt="enter image description here"></p> <p><strong>How it should be:</strong></p> <p><img src="https://i.stack.imgur.com/OAtM4.png" alt="enter image description here"></p> <p>What the best way to do that? Thanks!</p>

    1. COI'm not familiar with cocos2d, but it sounds like you'd be better off tracking the touches yourself and determining the direction by keeping track of previous x,y and current x,y. A swipe gesture is usually a fixed cycle gesture (you do it once) and doesn't trigger for continuous motion (otherwise everything would be a swipe). In standard UIKit you have touchesMoved: method which gets called whenever a touch moves on the screen. Not sure what the cocos2d equivalent is, but it might be worth looking into.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
