I’m currently using TestFlight in order to get remote crash reports on a beta version of our app. I’ve received a stack trace, however I’m not quite sure how to narrow down the problem. Here’s the report I’ve received:

Unfortunately the last 8 items in the stack trace don’t appear to be symbolicated. Is there a way for me to do this? I’m assuming hte problem is related to ABRecordCopyValue however I’m not 100% certain. Since I don’t know what the last two Holler calls are, I’m somewhat confused. Anybody have an idea about what I should do to narrow down the problem?
I believe the problem now resides within a specific method as the sequence of events (ABRecordCopyValue) followed by two Holler calls is repeated. Here’s the code … I’m using it to load up a user’s phone book/contact list. Let me know if this provides any more details:
ContactLists *list = [ContactLists defaultLists];
//Delete the phone contacts, and load them
[list clearContacts];
//Load them
ABAddressBookRef addressbook = ABAddressBookCreate();
if( addressbook )
{
//Got this via http://stackoverflow.com/questions/4641229/code-example-for-abaddressbookcopyarrayofallpeopleinsourcewithsortordering
ABRecordRef source = ABAddressBookCopyDefaultSource(addressbook);
CFArrayRef sortedPeople = ABAddressBookCopyArrayOfAllPeopleInSourceWithSortOrdering(addressbook, source, kABPersonSortByFirstName);
//Sort them first
if( sortedPeople )
{
CFIndex contactCount = ABAddressBookGetPersonCount(addressbook);
for( int i = 0; i<contactCount; i++ )
{
ABRecordRef ref = CFArrayGetValueAtIndex(sortedPeople, i);
NSMutableString *fName = [[[NSMutableString alloc] init] autorelease];
NSMutableString *lName = [[[NSMutableString alloc] init] autorelease];
NSMutableDictionary *identifiers = [[[NSMutableDictionary alloc]init]autorelease];
if( ref )
{
//Get the user's name first
CFStringRef firstName = ABRecordCopyValue(ref, kABPersonFirstNameProperty);
if( firstName )
{
NSString *fn = [NSString stringWithFormat:@"%@",firstName];
if([fn hasPrefix:@"(null"])
[fName appendString:@""];
else
{
[fName appendString:[NSString stringWithFormat:@"%@", firstName]];
[fName setString:[fName stringByReplacingCharactersInRange:NSMakeRange(0,1) withString:[[fName substringToIndex:1]uppercaseString]]];
}
CFRelease(firstName);
}
CFStringRef lastName = ABRecordCopyValue(ref, kABPersonLastNameProperty);
if( lastName )
{
NSString *ln = [NSString stringWithFormat:@"%@",lastName];
if([ln hasPrefix:@"(null"])
[lName appendString:@""];
else
[lName appendString:[NSString stringWithFormat:@"%@",lastName]];
CFRelease(lastName);
}
//If there is no first name don't deal with adding this contact to the ContactsList
if( [fName isEqualToString:@""] )
{
continue;
}
//Handle phone and email contacts
ABMultiValueRef phoneRef = ABRecordCopyValue(ref, kABPersonPhoneProperty);
if(phoneRef)
{
for( int i = 0; i<ABMultiValueGetCount(phoneRef); i++ )
{
CFStringRef phone = ABMultiValueCopyValueAtIndex(phoneRef, i);
if (phone) {
//Create the contact and add them to the phone contactList
NSString *mobileLabel = (NSString *)ABMultiValueCopyLabelAtIndex(phoneRef, i);
if( [mobileLabel isEqualToString:(NSString *)kABPersonPhoneMobileLabel] )
[identifiers setValue:(NSString *)phone forKey:@"Mobile:"];
if( [mobileLabel isEqualToString:(NSString *)kABPersonPhoneIPhoneLabel] )
[identifiers setValue:(NSString *)phone forKey:@"iPhone:"];
if( [mobileLabel isEqualToString:(NSString *)kABPersonPhoneMainLabel] )
[identifiers setValue:(NSString *)phone forKey:@"Main:"];
if( [mobileLabel isEqualToString:(NSString *)kABWorkLabel] )
[identifiers setValue:(NSString *)phone forKey:@"Work:"];
if( [mobileLabel isEqualToString:(NSString *)kABHomeLabel] )
[identifiers setValue:(NSString *)phone forKey:@"Home:"];
if( [mobileLabel isEqualToString:(NSString *)kABOtherLabel] )
[identifiers setValue:(NSString *)phone forKey:@"Other:"];
CFRelease(phone);
[mobileLabel release];
}
}
CFRelease(phoneRef);
}
ABMultiValueRef emailRef = ABRecordCopyValue(ref, kABPersonEmailProperty);
if (emailRef) {
if (ABMultiValueGetCount(emailRef) > 0) {
CFStringRef email = ABMultiValueCopyValueAtIndex(emailRef, 0);
if (email) {
[identifiers setValue:(NSString *)email forKey:@"Email:"];
CFRelease(email);
}
}
CFRelease(emailRef);
}
if( [identifiers count] > 0 )
{
//This is where I believe the problem is happen as it's two calls to internal Holler models
[list addContact:[[[Contact alloc]initWithIdentifiers:identifiers firstName:fName lastName:lName]autorelease]];
}
}
}
CFRelease(sortedPeople);
}
CFRelease(addressbook);
CFRelease(source);
}
You really need to symbolicate the Holler methods in the stack trace. Here’s how:
Go to TestFlight –> Select the Builds tab, then click the Testers button under the build that you are having issues with. Scroll down to the bottom and click on the bit.ly link that can be used to manually notify testers. At the bottom of that page, it gives you the option to download the .ipa file that you previously uploaded. Download it.
Once downloaded to your computer, rename the file extension from .ipa to .zip. Then unarchive it, and you should get the .app file. Since you only have the stack trace and not the full crash report, you can’t use XCode to symbolicate, but you can do symbolication manually using the instructions found here: http://www.bartlettpublishing.com/site/bartpub/blog/3/entry/311
Hope that helps, and I’d love to be a beta tester for your future apps!
