How to: In-App Purchase On Sale on the App Store

Changing the price of an app on the App Store is pretty straight forward. You go to the Pricing tab of your app in iTunes Connect and then edit it with the Tier you want. You must remember to set a starting date and an ending date. (Use Now to set the price change right away, and use None on the ending date if you want to keep that price indefinitely.)

If you have in-app purchases for a particular app, and you want to change the pricing for them, you must then go to the In-app purchase tab in iTunes Connect then click on the in-app purchase you want to edit. On the popup screen you will see the current setting for that in-app purchase but you have to click on the edit button to change any data including the price.  Then you can choose the new pricing exactly as you do with the app pricing, setting a new tier, starting date and ending date.

Pretty easy, eh? It took me five minutes to change all the in-app purchase prices on my 60 Top Hat Piano Grooves Vol. 1 app which is now ON SALE for $3.99 (was $4.99) and every single module is now $0.99 (were $1.99) except for the rock & pop grooves since there’s quite a few more of those.

Now you can buy 60 lessons with video tutorial & demo, compete piano score, metronome included in the score to practice all for only $3.99,

less than 7 cents $0.07 a lesson, how ridiculous (“amazing”.- I meant)  is that!

Building an App on iOS 8 still compatible with iOS7

My new app 20 Saxophone Tricks of the Trade by Mario Cerra has been available on the App Store for over a week now.

We’ve had many downloads apparently with no issues. Yesterday a user wrote us an email saying the app was crashing right after launching. I knew right away it had something to do with the user’s device or IOS.

I downloaded the app from the App Store on an iPad running IOS 7.1.1 and the app crashed right away. I tried it in XCode with the iPad 2 simulator and the app run perfectly but, as soon I connected my iPad with IOS 7 and run it from XCode the app crashed again with an uncaught exemption error.

Long story short, after a few break points I found the issue was in a line where I’ve used containsString to find if a substring is contained in a string, which is an iOS 8 only method. Although the app was set to build for ios 7.1 and up the xcode compiler gave me no warning notice.

The solution is to use the rangeOfString method that is compatible with iOS 7:

[yourString rangeOfString:@”whatever-you-are-looking-for string”].location == NSNotFound

That solved the problem.
To submit a new version of the app to the App Store you must change the version number and build number of the app, archive it and submit it.

Now the app is back on waiting for review on the App Store.

I also added a note in the description for the current version of the app so users still running IOS 7 will wait for the update before buying it.

 

– (NSString*) archivoFullPath: (NSString *)archivo {
NSMutableString* result = [NSMutableString stringWithString: mDecksURLFolder];
if (!([archivo rangeOfString:@”http”].location == NSNotFound)) {
return archivo;
} else {
[result appendString: archivo];
return result;
}
}

Today we submitted the new version of 60 Top Hat Piano Grooves Free.

I added 4 modules that are available as in-app purchases,using the method I described on my previous post In App Purchase

60 Top Hat Piano Grooves is a great piano app for piano students and players who want to improve their comping technique in many different styles.

We will see how long it takes…

Waiting for review on the App Store…

I just finished submitting a new app to the App Store:

20 Saxophone Tricks of the Trade by Mario Cerra.

Mario Cerra is an unbelievable jazz saxophone player  ( I met Mario a few years back when we were studying at Berklee College of Music in Boston) and I asked him to share 20 of his tricks and concepts when improvising at the saxophone, with the hope of creating a great Mobile app with video tutorials, demos, scores and backing tracks for practicing.

I should add, I’ve just finished my piano app a couple of weeks ago, and is already available on the App Store, got a few nice reviews and we are waiting to see how it does on the App Store.
