To Implement the Omniture Tracking in an iPhone Application, I have downloaded the AppMeasurement software from SiteCatalyst(AppMeasurement.h,libAppMeasurement.a,libAppMeasurementNoThumb.a). I am using Omniture's app measurement iphone library, linked the release and dev libraries. I instantiate them using the singleton method (getInstance). Implemented as below <pre><code>#import "OmnitureTracking.h" #import "AppMeasurement.h" AppMeasurement *s = nil; @implementation OmnitureTracking + (void)beginTracking { s = [[AppMeasurement getInstance] retain]; s.account = @""; s.debugTracking = YES; } </code></pre> Calling this 'beginTracking' in AppDelegate to initiate the tracking, for pagetracking implemented another method as below: <pre><code>+ (void)trackViewForPage:(NSString *)pageName { NSLog(@"trackViewForPage::s instance::%@::",s); if (s == nil) return; [s clearVars]; [s track:[NSDictionary dictionaryWithObjectsAndKeys:pageName, @"pageName", nil]]; } </code></pre> Implementaion working fine and getting below log: <pre><code>2012-06-21 01:53:20.953 MyApp[857:607] App Measurement Library compile time = Aug 4 2011 16:29:52 2012-06-21 01:53:21.418 MyApp[857:607] trackViewForPage::s instance::<AppMeasurement: 0x28c4b0>:: 2012-06-21 01:53:21.795 MyApp[857:607] Omniture App Measurement Debug: http://MyApp.net/b/ss/MyAppiosappdev/0/OIP-2.1.2/s2253418?AQB=1&ndh=1&t=21/5/2012%205%3A53%3A20%204%20240&vid=01398194867219045&ce=UTF-8&pageName=MyApp%201.2%20%281.2%29%20Launch&ts=2362139876678&events=event7%2Cevent5&c1=D%3Dv2&c2=D%3Dv6&c3=D%3Dv11&v2=MyApp%201.2%20%281.2%29&v4=0&v5=0&v6=20&v7=5&v8=Thursday&v9=4.3.3&v12=D%3Dv3&v13=D%3Dv3&s=320x480&c=24&AQE=1 </code></pre> But when app goes background and enters foreground, app is crashing because of Tracking and getting the log as below: <pre><code>Jun 21 03:07:41 unknown MyApp[467] <Warning>: trackViewForPage::s instance::( "" ):: Jun 21 03:07:41 unknown MyApp[467] <Error>: -[__NSCFArray clearVars]: unrecognized selector sent to instance 0x28c4b0 Jun 21 03:07:41 unknown MyApp[467] <Error>: *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFArray clearVars]: unrecognized selector sent to instance 0x28c4b0' </code></pre> "AppMeasurement" instance becoming nil or empty when app goes background and enters foreground, but I am not able to figure out whether its the Site Analyst iPhone Library issue or Coding issue. To handle the crash,I have done the nil check, but its not falling under nil case. Please help me in figuring out the "AppMeasurement" instance empty check and why "AppMeasurement" instance becoming empty when app goes background and enters foreground. Thanks

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
