So I have an app called TimeTag that uses Core Data and I needed to migrate to a new core data model version. It uses a UIManagedDoc to manage the core data file (rather than having everything dumped in the AppDelegate). I did the usual first steps:I selected my ModelName.xcdatamodelId in my project list and went up to "Editor" and selected "Add Model ......

Last night I was doing one of the things I normally do throughout the day: Search Twitter for my app names to see if anyone is tweeting about my company or one of my apps. But tonight, unlike many other nights, there were tons of tweets all in Japanese with just the word 'TimeTag' in English. I got excited: Someone wrote about us in Japan, so I clicked ......

This is an exciting Friday. My first game, Doodle Space Fighter ( https://itunes.apple.com/us... launched for the iPhone today. I'm doing a soft launch this weekend with just my own personal blogs and friends/family, and then doing a bigger one this upcoming week. Honestly I don't care if it only sells 5 copies, ......

Since "Doodle Fighter" (working title) is the first game I've ever worked on, a lot of the code started off as you might expect: tons of things cobbled together, none of it properly encapsulated, and a lot of it hard coded. The last week I've been focused on pulling a lot of this data out and I decided that one thing I wanted to do (after reading that ......

I've been working on developing my first iPhone game for a couple of months now but recently I've been able to commit more time to coding it, since I finished school earlier this month. In short, the game is like Galaga, but it's with doodle graphics and includes the ability to upgrade your ship throughout the levels. The idea will be that your ship ......

I have an app that has been on the store since iOS 3.1, so there is a large install base out there that still uses Core Data loaded up in my AppDelegate. In the most recent set of updates, I raised the minimum version to 4.3 but still kept the same way of loading the data. Recently, I decided it's time to make the minimum version 5.1 (especially with ......

This drove me nuts for a few hours, but finally figured it out. I wanted to go ahead and share, since the web results I found when I was searching were only a few pieces here and there, and still didn't offer a final solution. So the scenario I encountered was that I have a UIViewController that will sometimes host a subview (that is another viewcontroller) ......

This is just a quick tutorial to help you write in an in-app help menu using a .plist file. As apps become more complicated (especially if you continue to add onto your 1.0 version with more features), it's easy to get lost in them. And a good built-in support system is appreciated by everyone. I also prefer to keep it in-app because then it's formatted ......

I am currently working on making a free version of my iOS application. I followed a fantastic tutorial a while back (http://www.bit-101.com/bl... ) which got me up and running with a free and regular version, sharing the same code base. This is great, because changes made will be mirrored across both versions, so you don't have the nightmare ......

I ran into this problem this morning and thought I’d share in case someone else has this issue .So I’m using PredicateBuilder with the EntityFramework and doing some pretty basic query building. I have a list of business types that the person can select (a checkboxlist) and then it returns everything that matches. I was having an issue because it was ......
