Ios – iPhone web app from dashcode RSS feed template works when deployed on a simulator, but not on iPhone

A shot in the dark, but the apple docs say this.

the domain of the URL request destination must be the same as the one that serves up the page containing the script. This means, unfortunately, that client-side scripts cannot fetch web service data from other sources, and blend that data into a page. Everything must come from the same domain. Under these circumstances, you don't have to worry about security alerts frightening your users.

What are the values of status and statusText? Also try getAllResponseHeaders() for more info.

Also, if it's just basic auth you want, you can just pass it to open() like so:

open("method", "URL", asyncFlag, "userName", "password")

I obviously do use something like this ...

#import <TargetConditionals.h>

#if TARGET_IPHONE_SIMULATOR

// Simulator specific code

#else // TARGET_IPHONE_SIMULATOR

// Device specific code

#endif // TARGET_IPHONE_SIMULATOR

And to your second question ... Something like this should help you. In your app delegate:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  if ( ! [[NSUserDefaults standardUserDefaults] boolForKey:@"initialized"] ) {
    // Setup stuff
    [[NSUserDefaults standardUserDefaults] setBool:YES forKey:@"initialized"];
  }

  ... your code ...
