Scrolling credits on iOS – how to create.

Thursday, June 16th, 2011

Ever wanted to have scrolling credits for your iOS device ? Here is how to do it…

Scrolling Credits from Brian Slack on Vimeo.

1. Take your existing photo and cut out a piece as high as your UIView and as wide as your text plus a little bit.
2. This new image will be our mask.
3. With the mask image cut out the centre so you have a rectangle top and bottom. Clone the layer and on the first layer delete the bottom rectangle, on the other layer delete the top rectangle
4. Add a layer mask to both.
5. With the layer mask selected add a black/white gradient (hold down the shift key to get a straight down gradient)
6. Your mask image is now done, add to your XCode project with the main image then the text and then the mask image on top.
7. To animate first reset the text so it’s always in the same starting position

lblCredits.transform = CGAffineTransformMakeTranslation(0, 0);     
CGRect frame = lblCredits.frame;
frame.origin.y = 550.0;
lblCredits.frame = frame;

8. Then just animate up

[UILabel beginAnimations:nil context:NULL];
[UILabel setAnimationDuration:30.0f];
[UILabel setAnimationCurve:UIViewAnimationCurveLinear];
[UILabel setAnimationBeginsFromCurrentState:YES];
[UILabel setAnimationDelegate:self];
[UILabel setAnimationDidStopSelector:@selector(creditsHaveEnded)];
CGAffineTransform transform = CGAffineTransformMakeTranslation(0, -1000);
lblCredits.transform = transform;
[UILabel commitAnimations];

9. That’s about it, dependant on how you use it you may need to cancel the animation but I’m sure you can work that out :)

XIB iPad orientation in landscape problem and solution

Wednesday, January 26th, 2011

If you want to show a secondary nib file you may have noticed that it shows fine in portrait mode but from startup not in landscape mode.

This is what I use to fix this. Seems like a fudge but it works, I call this after creating the view.

vSettings is a UIView and backGroundSettings is a UIImageView.

- (void) animateFlipInView:(NSString *)theNib;
{
    UIInterfaceOrientation toInterfaceOrientation = self.interfaceOrientation;
    NSArray *nibObjects = [[NSBundle mainBundle] loadNibNamed:theNib owner:self options:nil];
    vSettings = [nibObjects objectAtIndex:0];
    [self.view addSubview:vSettings];
    if (iPadCheck)
    {
        if ((toInterfaceOrientation == UIDeviceOrientationLandscapeLeft) || 
			(toInterfaceOrientation == UIDeviceOrientationLandscapeRight)) 
        {
            CGRect contentRect = CGRectMake(0,0,1024,768);
            vSettings.bounds = contentRect;
            CGRect myFrame = vSettings.frame;
            myFrame.origin.x = 0.0;
            myFrame.origin.y = 0.0;
            vSettings.frame = myFrame;
            UIImage *image;
			image = [UIImage imageNamed: @"Default-Landscape.png"];
            [backGroundSettings setImage:image];
		}
    }
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:1.0];
    [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.view cache:YES];
    [UIView commitAnimations];
}

WoL Monitor a hit ?

Saturday, December 4th, 2010

Well the numbers are in for the first two days. To say I am a bit shocked would be an understatement as it seems 199 people thought it was an app they needed. This is strange as my WoL sender app gets about 6 downloads a day and has been live a month, clocking up 239 downloads so far.

Looks like people want to monitor WoL more than they want to send WoL magic packets :)
