Re: iphone SDK session duration
Sorry for the delay in response. I'll need more help.
I follow suggestions on using applicationDidFinishLaunching: and
applicationWillTerminate: methods on AppDelegate.
It won't print NSLog when I stop the app on Console and throw errors when I
leave the app on simulator by pressing the home button to exist the app like
the device.
I didn't get any warnings or errors on building the project.
I used NSLog(@Session: %.1f, [now timeIntervalSinceDate:then]);
Please help!
*project code:*
http://code.google.com/p/iphonebuilder/downloads/list
- (void)applicationDidFinishLaunching:(UIApplication *)application {
// Starting Session
}
- (void)applicationWillTerminate:(UIApplication *)application {
// Ending Session
}
*Errors on console when I exit the app on simulator*

How do you measure session duration on a utility application with 3
ViewControllers?
Use NSDate to mark the starting and ending the session and print the time
lapsed on NSLog.

Re: iphone SDK session duration
I did reply. Moderator on this list rejected because my reply is too long. I was about to report the results. I get it to work. I open source the Xcode project code on google project if anyone want it.

Just looking at this I can tell you the problem is the now object is
not an NSDate - it's an NSObject. You need to create a valid NSDate.
