The deprecated way:
NSArray *fileList = [manager directoryContentsAtPath:productDirectory];

replace directoryContentsAtPath with contentsOfDirectoryAtPath & you must also add error:nil

The new hotness:
NSArray *fileList = [manager contentsOfDirectoryAtPath:productDirectory error:nil];

I also use AdMob and have always been pretty happy with them but I keep hearing about how much better the iAds are paying out. The one big drawback to iAds being you don’t get as many ads as you would with AdMob. I understand there are some advertising networks out there that allow you to take advantage of multiple ad networks. The problem there is that you are under their control and who knows how and when they regulate those ads. So why not take control yourself?

So I began searching for a method of integrating both myself. Fortunately I found a post on the xcode noobies blog. They had a blog post outlining something very similar to what I was looking to accomplish. Their code was designed to display an iAd unless the app was being run on a device running iOS 3.2 which doesn’t support iAds. So instead of loosing revenue on older devices their intent was to load AdMob Ads as backup. So, I modified their code to load AdMob Ads as a fallback whenever an iAd is not available – rather than just when the OS version was too old to support iAds. I think this is ultimately more useful. The OS detection code is still present but not very necessary. Just make sure if you are  targeting iOS 3.2 or below to WEAK LINK the iAd Framework.

UPDATE: 9/29/11: After experimenting with the project below for some time I have found it to be quite troublesome and buggy. I am leaving the code up as it may be a good starting point for someone but use at your own risk!

Code calls 1st for the iAd and 2nd for the AdMob Ad – If an iAd is available it’s displayed right away. If not,  hopefully an AdMob ad is displayed. Even when AdMob ads are being displayed the app checks for iAds (refresh time is controlled by Apple) and loads them as soon as they are available.  AdMob Ads are refreshed every 30 seconds in code (you can adjust this.) Hopefully with this we can all maximize our income =) The project can be downloaded HERE.

Now I have to warn you. I have no idea if this method of doing things is 100% correct. I’m not an expert. This project uses a 9 month old version of the AdMob SDK. I have tried unsuccessfully to update the code to run with the latest Google/AdMob SDK.  I was able to update the code to utilize the latest Google/AdMob SDK version 4.1.1 =) Enjoy!

What is Easy APNs?
If you are a native iPhone application developer, you may have heard of the Apple Push Notification service (APNs). There are a lot of excellent online guides on how to get your application to receive remote notifications… but what about the other piece of the puzzle… ACTUALLY SENDING A MESSAGE?!?!

This very cool project is brought you by Manifest Interactive.

*NOTE: I was NOT able to get this up and running on GoDaddy Hosting for some unknown reason, but the same exact files worked flawlessly on (mt) MediaTemple

NSString *contents = [NSString stringWithContentsOfFile:fullpath];

After doing a bit of Googling I found the solution.

Replace NSString *contents = [NSString stringWithContentsOfFile:fullpath]; with:

NSString *contents = [NSString stringWithContentsOfFile:fullpath encoding:NSUTF8StringEncoding error:nil];[NSString stringWithContentsOfFile:fullpath encoding:NSUTF8StringEncoding error:nil];

(Side Note: Ever since I began coding my vocabulary has expanded. Now I get to use words like Redacted and Deprecated Thanks Apple!)

What this means is that I can no longer test code on my phone

After a quick search I found the solution posted on the iphonedevsdk forums! The original post can be found at http://www.iphonedevsdk.com/forum/iphone-sdk-tools-utilities/21005-xcode-3-1-3-3-0-7a341.html

For those of you who just want the fix and want it now, here it is . . .

(Just paste this line into a terminal window while XCode is closed)

ln -s /Developer/Platforms/iPhoneOS.platform/DeviceSupport/3.0\ \(7A341\) /Developer/Platforms/iPhoneOS.platform/DeviceSupport/3.0.1

That did it for me, hopefully it helps you!

If you write an app that depends on internet access in order to function properly Apple requires that you detect the state of the connection and report it to the user when that connection is unavailable. If you do not Apple will reject your app on the basis that it is confusing to the user. Confusing because the app does not work and Apple assumes that the user will not understand why. Makes sense.

Here is one way to determine whether or not the users device has airplane mode enabled . . .

1. Add SBUsesNetwork to the Info.plist
2. Change its type to Boolean
3. Add a check mark to enable

Here is handy little project that detects whether or not your application has access to a WiFi network:

Download TestWifi_3.0.zip

Here is another handy little project that detects whether or not your application has any network access:

Download NetConnectDetection_3.0.zip

Feel free to use any of the above code in any way you wish. I am providing it in the hopes that it will help save someone from the headache that I experienced all day yesterday trying to get network detection to work

If you find any errors or corrections please notify me and I will update the sample apps. Thanks!

You have to add the line

UIPrerenderedIcon

to your Info.plist file. Change its value to boolean and then add a check mark like below . . .

That will change this into this :
