I would like to detect when user has clicked on the left button of each cell (minus circular red button, the one that is animated with a rotation), just before the "Delete" button appears. I would like to be able to change my cell content in...

I have a class named SuperclassA, and an class named ClassA. ClassA inherits from SuperclassA. SuperclassA has got an property called something, so a very generic not-much-saying name.

Does this seem right, the dataFilePath is on disk and contains the right data, but the MSMutable array does not contain any objects after the initWithCoder?

I'm leaning towards the idea of moving the save step into my appDelegate and havi...
Hi all, I am writing a very simple application, for the iPhone. Unfortunately I am really a newbie. What I am trying to do is to save data at the end of a user experience.

I work with a lot of random numbers to create constantly shifting textures. I'm getting tired of doing things like: ((rand() % 1000) / 10) + 100 when I really want something like [randomUtils randomNumberBetween:100 and:200] Additonally, I'd like to be able to manipulate weights of the randomization, so that, for example, my val...
The ones they use with grouped table view. I'm using a table view that links to another view that has text on it. To make it look less 'plain' I wanted to add that striped background and then put something like a white 'text box' on that. Do they allow it to be used? ...

I have a UITableView with UIWebViews within the cells for the purpose of displaying rich text. The UITableViews load html strings locally.

I am working on understanding Core Audio, or rather: Extended Audio File Services Here, I want to use ExtAudioFileRead() to read some audio data from a file. This works fine as long as I use one single huge buffer to store my audio data (that is, one AudioBuffer). As soon as I use more than one AudioBuffer, ExtAudioFileRead() returns th...
