Hello, I'm developing an iOS app that needs to connect to Twitter, Facebook, Google, Yahoo, Gowalla and Foursquare via OAuth. I have been using http://github.com/dbloete/oauth-objc and that works fine with Twitter (OAuth v.1, basic implementation), but has problems with everything else (it seems that each provider has different standards...

I have very big unsigned integral number in NSString. This may be big to 2^64. Is there an existing functions/classes parsing this? As I know, it's unsigned long long value, but, It's hard to know what kind of method should I use to parse this. ...
I'm working with a Core Data project in iOS 4.1 (targeting 3.1). When I add a Data Model version I get the dreaded "Can't merge models with two different entities named xxx" error."

Within my iPhone application I periodically make calls to a webservice, providing the endpoint with a list of numeric IDs. The webservice then returns information relating to the IDs it receives. This is all well and good. However, I would like to be able to provide functionality whereby the user will receive a local/push notification w...
I've been writing some code that replaces some existing: while(runEventLoop){ if(select(openSockets, readFDS, writeFDS, errFDS, timeout) > 0){ // check file descriptors for activity and dispatch events based on same } } socket reading code.

In the following UIView animation block, I do a CGAffineTransformMakeScale and a CGAffineTransformMakeRotation, and though the duration is set to 1.0f, the scale goes really fast and the rotation goes in 1 second like it should. It must be my lack of understanding about how AffineTransforms are applied but I can't figure it out. What g...
Here's a follow up to a previous question. My code below animates a square by scaling it and rotating it. It does this by making a rotation transform and adding a scale transform to it. That works fine. When it's done, it calls throbReset. I used to have throbReset just set self's transform to a CGAffineTransformMakeScale and that w...
I have a UITableViewController that is presented with a list of choices. After the user taps one, I'd like to return to the previous view. The return seems too quick with the code I'm using though. I'd like to pause for 0.2 seconds or so to give the user time to see their selection become checked. Here's the code I'm using now: - (void)...

I recently submitted a new version of my app to the app store, and increased the Deployment Target to 3.2, to make the app no longer able to install on iOS 3.1.3 which is not compatible with it. However, when the app went live on the store, it still is listed as "Compatible with iOS 3.1.3 or later." How can I increase the minimum iOS ver...

I've heard some conflicting things about the acceptability of scripting languages (e.g., Lua) in apps for the App Store. I'd like to hear from anyone who understands the policy regarding apps which contain some level of programmability, or someone who has had experience submiting such an app for approval. For instance, suppose I want t...
