I am looking for some suggestions on how to secure access to a RESTful API which initially be used by an iPhone application, but will have other clients in the future. The data exposed by this API must be kept secure as it may contain health information. All access will be done over HTTPS. I was thinking that I'd like to require pre-reg...
I'm building an iphone app that needs to access a web service over https using client certificates. If I put the client cert (in pkcs12 format) in the app bundle, I'm able to load it into the app and make the https call (largely thanks to stackoverflow.com). However, I need a way to distribute the app without any certs and leave it to ...

I have an app with with a UITabController and each tab is a UINavigationController. The root of one of my UINavigationControllers is a UIViewController. Inside that view controller's view, I want to layout some subviews, but I'm confused as to where & how to lay them out in a way that will be resolution independent (i.e. not hardcode va...

I've added a UITableView component to a ViewController in Interface Builder to make it easier to customise as the UITableViewController won't let me set a background image. I've then implemented some basic functions just to test if it works, but cannot get it to display any cells - does anyone have any suggestions on how to get it worki...
I have created a Settings bundle for my iPhone app, with a multivalue specifier called Choice 1. The titles and values arrays are both correct - titles is strings, and values is 1-5. I set the default value to be 5, but it always stays as the first title in my array, and also the actual value doesn't appear next to the title of the ...
This is really weird, hopefully a fresh pair of eyes can help me figure this out. I happen to be using this code in an iPhone App, but I believe it's using simple C code so not sure this makes a difference or not. I have the user input a number (in this case the num will be 2.2). I then divide that number by 0.2. On my calculator I get...
I am using the following code to come up with a number. NSString *userNameOne = txtUserName.text; double numOne = [userNameOne intValue]; double agedecade = numOne/10; double betaage = 0.23260; double meanage = 5.64301; double one_age = agedecade - meanage; double age_final_var = one_age * betaage; If the user input 55 into the num...

I am writing an iPhone app that needs to be able to upload photos to Facebook as a side effect of sending them in an email. It seems like a gigantic pain to create the album and upload the photos; is there any way that I can get the user's personal upload email through the API and just add that to the recipients in the email that is sent...
Can anyone provide an explanation of how I would go about uploading several photos to Facebook from my iPhone application using FBConnect? I've been reading the documentation, and I'm sort of stumped. ...
I was trying recycle code for saving an image and attaching it to an email, with no luck. After I get the three values out of the PeoplepickerNavigation controller I want to save them for use and place them as text into an email.

Hi all. I'm working on an iPhone OS app whose primary view is a 2-D OpenGL view (this is a subclass of Apple's EAGLView class, basically setting up an ortho-projected 2D environment) that the user interacts with directly. Sometimes (not at all times) I'd like to render some controls on top of this baseline GL view-- think like a Heads-U...
