I ran into this last night- I used the sample from Xcode 4, “tab bar application.” I wanted to solve this problem I was having- I was assigning a UITableViewController to one of my Tab Bar Items, but I got a crash each time, with “retavalue” and “numberOfSections.” No matter how I set it up, [...]
I was surprised at how easy it was to implement a “share story” in my iPhone app. I’ve used ShareKit before, and I actually found the Facebook SDK created by FB to be easier! Note- I’m doing something very simple, publishing a share story. (Yes, that’s the new timline view.) 1. First, download it. In [...]
Just finished implementing in-app purchases for Russian Bingo. I implemented a button in the last version, to determine how many of our users actually wanted more vocabulary levels. Well, it is hovering around 10% for Russian and 30% for Mandarin. Note though that Russian has a much larger sample set- at 2K – than Mandarin [...]
I’ve been thinking of making this app ever since we started the Bingo franchise. This is perhaps the hardest language I’ve learned next to Russian, and was super excited to have a simple little game I can play casually. The other day I looked over my sister’s shoulder as she played with almost every Chinese [...]
I have been working in the same code base for a year now- the latest app is El Bingo if you want to check it out. In review, currently, I have Chinese Bingo and an upgrade to our first app, Le Bingueau (free until 9/16!). I’ve learned some very interesting things working and focusing on [...]
This had me up for a few nights, so here is my solution. I think someone at #iosDevCamp asked me this same question, too – I think it was Sophia. Problem: You have an iPhone app with a UIRootViewController, tab navigation, with a UIButton that launches a UITableViewController (a second view). When a user selects [...]
I occasionally spend an entire weekend, almost 24 hours in the day, hunkered over my computer in a fluorescent room, amongst others also lit by the back glow of their MacBooks. I can’t really explain this to non-technical friends and family. It’s San Jose, it’s July, it’s sunny … what exactly is the desire to [...]
This response really goes for almost anybody looking for a technical co-founder, CTO, start-up developer or prototype developer, and whether the compensation is split in equity, cash, or future shares. You are a person with an idea. An idea that you think is pretty nifty. It’s for [insert audience here] and it does [insert features [...]
Just came back from a great class taught by Adam Milligan of Pivotal Labs on Cedar. Download Cedar here: http://www.github.com/pivotal/cedar The Readme should be able to lead you through the setup fine, but I wanted to add my notes. – You’re essentially compiling Cedar, then taking the framework and associating it with your iPhone project. [...]
I’m working on a game that has a game board, that is relatively small array of 4-array objects; a “poor-man’s matrix”. This array, which changes, persists throughout the game view controller, so it’s a property, with the retain attribute. I got the game functional, but recognized a lot of memory leaks when setting up the [...]
