The user can choose whether he wants to use an existing image or take a new one for use as the background. Everything works as far as the FirstViewController is concerned. Sadly the image is no longer set as the background when the SecondViewController is displayed. How do I enable the use of the image as background for the SecondView...
Hi, This question isn't strictly development-related but I hope it's still acceptable :) I'm looking at creating an iPhone app that will communicate with a REST Web service. Because some user-sensitive data (name, address, age, etc) will be transmitted I'm looking at securing the connections with SSL. However, on my previous escapades...

I've been working on autoresizing a custom UIView and Apple has very little to say on this. What's more, based on SO feedback, Apple's documentation is actually wrong in some areas. Finally, even though there are six resizing components in Interface Builder and six for setAutoresizingMask: they don't seem to correlate at all. For example...

When I have the character array defined inline like: const char backButtonData[] = { 0x00, 0x01, 0x...

I am using NSFetchedResultsController along with a UITableViewController. I've created a transient field in my Core Data model to use as a label for my UITableView sections. The name of the field is "sectionIndex". In my application, a "Client" entity has many "Jobs" (1 to many) - so my query to retrieve Jobs groups them (via section) b...

I have read into the keychain and have found that it uses Triple DES. What I can't find is what keying option it uses. I am guessing / hoping that its keying option 1 where all 3 passwords are unique but if thats the case I can only think of two passwords it can use (user password and App ID that comes from your dev cert) so where is the...
You can view the Java API in tree structure. So you can view all the subclasses of Object. How would I view all the subclasses of UIView or NSObject IPhone Cocoa API? I just found out you can do this: self.tableView.tableHeaderView = searchBar; searchBar is subclass of UIView. I want to add a textField to a tableView. I wonder if ...
I have heard that there are some apps that hook into the Apple processes that will run in the background (namely, hooking into the Apple clock timer API), which will allow some non-UI background process on your 3rd party app to continue to run. Is this legitimate? Supposedly, there are some GPS-tracker apps that are using this and have p...

I'm writing some code to acquire images that live on a server. The image filenames are in yyyyMMdd_HHmm format (in UTC) and generated every 3 hours (1200,1500,1800,..etc).
