  - by user117758

  I have an iPhone application which has a button to change display language in run time.

• Is the Keychain suitable for storing general data, such as strings?

  - by cannyboy

  The Keychain seems to be used a lot for usernames and passwords, but is it a good idea to use it for other sensitive stuff (bank details, ID numbers etc), but with no password? What kind of encryption does the keychain use? The scenario I'm concerned about is a thief acquiring an iPhone (which is screen-locked) and being able to access the file system to get this info. Also, would using the Keychain involve export restrictions due to the use of encryption?

• is there a way to disconnect from facebook login without calling logout

  - by Joey

  Basically, I'd like to know how I can logout of my facebook session if I am in an iphone app and have connected to facebook (such that I do not have to repeatedly enter my login/password). Normally you'd disconnect in the app somewhere like in the options, but if this is not available (i.e. anything that triggers the FBSession logout method) is there some other way to do it? I'm guessing one could restore their phone to factory settings or something.

  I'd like to use the Tapku library to add a calander date picker control to my iPad app. I'm new to iPhone OS development and I'm still rusty on identifying the 3rd party tools and code that will get my iPad app denied from the app store.

• Change texture opacity in OpenGL

  - by zoul

  Hello! This is hopefully a simple question: I have an OpenGL texture and would like to be able to change its opacity, how do I do that? The texture already has an alpha channel and blending works fine, but I want to be able to decrease the opacity of the whole texture, to fade it into the background. I have fiddled with glBlendFunc, but with no luck – it seems that I would need something like GL_SRC_ALPHA_MINUS_CONSTANT, which is not available. I am working on iPhone, with OpenGL ES.
