FlurryAds Interstitial ads with Cocos2d v3

This is my first foray into ad-supported territory. I am really liking Cocos2d and recently my focus has been on the newest v3 (currently rc4). In this tutorial we will put up some interstitial ads for iphone and/or ipad.

Cocos2d v3 has a great new installer. It gives you a couple options in XCode. It’s even compatible with the latest XCode (5.1) and ARC.

-all those frameworks.
AdSupport.framework (Mark as Optional to support < iOS 6.0)
CoreGraphics.framework
Foundation.framework
MediaPlayer.framework
Security.framework
StoreKit.framework (Mark as Optional to support < iOS 6.0)
SystemConfiguration.framework
UIKit.framework

//do the first delegate stuff
In the AppDelegate.h go into the
-(BOOL) application: didFinishLaunchingWithOptions:

[Flurry setCrashReportingEnabled:YES];
[Flurry startSession:@"YOUR_API_KEY"];
[FlurryAds enableTestAds:YES];

Easy way to see (and debug) UILocalNotifications

It doesn’t take a lot of code to create a UILocalNotification but when you have multiple of them and you’re doing a lot of calendar math and things start getting hairy. To demystify that experience I created a project with a UITableViewController that prints out all of the current UILocalNotifications.

We’ll create 3 local notifications 1 minute apart for the next 3 minutes with these calls:

   [self createLocalNoticationAt:[[NSDate date] dateByAddingTimeInterval:60] withTitle:@"Every Minute 1!"];
    [self createLocalNoticationAt:[[NSDate date] dateByAddingTimeInterval:120] withTitle:@"Every Minute 2!"];
    [self createLocalNoticationAt:[[NSDate date] dateByAddingTimeInterval:180] withTitle:@"Every Minute 3!"];

Detect the end of a UILongPressGestureRecognizer

I am coding the previous/next buttons of a music player. I need these UIButtons to have dual purpose.

1. Tap – Previous/Next song
2. Long Press – Seek

That works, but what got me was that I didn’t know when the end of the long press was so I never knew when to stop seeking. I tried to attach an action to the UIButton on the UIControlEventTouchCancel event, but that is not correct.

This is my setup code:

    gestureSeekBackward = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(seekBackward:)];
    gestureTapBackward = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(previousSong:)];
    gestureTapBackward.numberOfTapsRequired = 1;
    [backwardButton addGestureRecognizer:gestureSeekBackward];
    [backwardButton addGestureRecognizer:gestureTapBackward];

What I needed to do was check whether the state is ended for the seek gesture. Continue reading

Change $PATH in Mac OS X Mountain Lion

I’ve had a bad time trying to get Jewelry Box running on Mountain Lion. I simply didn’t know how to edit my current $PATH.

Turns out there is a list it takes from at /etc/paths

I quickly changed the order and then after a trip to thew ‘brew doctor’ everything seems fine and now I’ve got ruby 2.0.0!

After much searching this is the great resource which I found:

Chaining UIView animations with blocks

I really love UIView animations. They are so simple and elegant. This little chain I will make will fade in a UIView (or descendant) from the left, wait a moment, then fade out to the left. In general you can animate all of these properties: frame,bounds,center,transform,alpha,backgroundColor,and contentStretch in a UIView animation block.

For this example I created a single view application and put a UIImageView in the middle of the screen. UIImageView is a direct descendant of UIView so it is perfect for this exercise.

UITableView Disclosure Indicator on a UIButton

Although it is non-standard. I needed to match pixel-perfect to a design, so I created this. On a UITableView it is called ‘Disclosure Indicator’ as opposed to the one available from UIButton which is ‘Detail Disclosure’.

table_indicator

It is 50×80 with a transparent background. Use this image on top of a button or UIImageView. Resize it to whatever size you’d like your button to be. Apple recommends a hit target of no less than 40×40. I sized it to 10×16 in my storyboard, but I am using a transparent button overlay so the size doesn’t matter.
