    <p>I'm having some memory leaks with both ABAddressBookGetPersonWithRecordID and ABPersonSetImageData. I've been looking for solutions before posting here but I still don't understand. If I play quite a long time with the iPhone 3GS or with only a few contacts with iPhone 3G, actually the application crashes. Here is my code in the didSelectRowAtIndexPath method. I've seen sample codes with these methods and I don't see what I'm missing. Thank you in advance. (sorry for mistakes...)</p> <p><code></p> <pre><code>Contact *myContact = [fetchedResultsController objectAtIndexPath:indexPath]; cancelCreateContact = NO; ABAddressBookRef ab = ABAddressBookCreate(); int len = ABAddressBookGetPersonCount(ab); ABRecordID contactID; ABRecordRef person; BOOL alreadyExists = NO; CFStringRef first, last; for(int i = 1; i &lt; (len + 1); i++) { person = ABAddressBookGetPersonWithRecordID(ab, (ABRecordID)i); if(!person){ len++; continue; } first = ABRecordCopyValue(person, kABPersonFirstNameProperty); last = ABRecordCopyValue(person, kABPersonLastNameProperty); if ([[(NSString*)first lowercaseString] isEqualToString:[myContact.firstname lowercaseString]] &amp;&amp; [[(NSString*)last lowercaseString] isEqualToString:[myContact.lastname lowercaseString]]) { alreadyExists = YES; contactID = ABRecordGetRecordID(person); break; } } if (alreadyExists) { //NSLog(@"already exists"); ABRecordRef aContactFound = ABAddressBookGetPersonWithRecordID(ab, contactID); ABRecordRef aRecord = ABPersonCreate(); CFErrorRef anError = NULL; CFStringRef firstname = ABRecordCopyValue(aContactFound, kABPersonFirstNameProperty); ABRecordSetValue(aRecord, kABPersonFirstNameProperty, firstname, &amp;anError); CFRelease(firstname); CFStringRef lastname = ABRecordCopyValue(aContactFound, kABPersonLastNameProperty); ABRecordSetValue(aRecord, kABPersonLastNameProperty, lastname, &amp;anError); CFRelease(lastname); CFStringRef job = ABRecordCopyValue(aContactFound, kABPersonJobTitleProperty); ABRecordSetValue(aRecord, kABPersonJobTitleProperty, job, &amp;anError); CFRelease(job); ABMultiValueRef instantMessage = ABRecordCopyValue(aContactFound, kABPersonInstantMessageProperty); ABRecordSetValue(aRecord, kABPersonInstantMessageProperty, instantMessage, &amp;anError); CFRelease(instantMessage); ABMultiValueRef phone = ABRecordCopyValue(aContactFound, kABPersonPhoneProperty); ABRecordSetValue(aRecord, kABPersonPhoneProperty, phone, &amp;anError); CFRelease(phone); ABMultiValueRef email = ABRecordCopyValue(aContactFound, kABPersonEmailProperty); ABRecordSetValue(aRecord, kABPersonEmailProperty, email, &amp;anError); CFRelease(email); CFDataRef imageData = ABPersonCopyImageData(aContactFound); ABPersonSetImageData(aRecord, imageData, &amp;anError); ABAddressBookSave(ab, &amp;anError); CFRelease(imageData); ABUnknownPersonViewController *ABView = [[ABUnknownPersonViewController alloc] init]; ABView.unknownPersonViewDelegate = self; ABView.displayedPerson = aRecord; ABView.allowsAddingToAddressBook = NO; ABView.allowsActions = YES; ABView.hidesBottomBarWhenPushed = YES; [self.navigationController pushViewController:ABView animated:YES]; [ABView release]; CFRelease(aRecord); }else{ //NSLog(@"doesn't exist"); //sinon ouvre une fiche pré-remplie ABRecordRef aRecord = ABPersonCreate(); CFErrorRef anError = nil; if(![myContact.firstname isEqualToString:@""]) ABRecordSetValue(aRecord, kABPersonFirstNameProperty, myContact.firstname, &amp;anError); if(![myContact.lastname isEqualToString:@""]) ABRecordSetValue(aRecord, kABPersonLastNameProperty, myContact.lastname, &amp;anError); if(![myContact.email isEqualToString:@""]) { ABMultiValueRef ABemail = ABMultiValueCreateMutable(kABMultiStringPropertyType); ABMultiValueAddValueAndLabel(ABemail, myContact.email, kABWorkLabel, NULL); ABRecordSetValue(aRecord, kABPersonEmailProperty, ABemail, &amp;anError); CFRelease(ABemail); } if(![myContact.phone_business isEqualToString:@""] || ![myContact.phone_mobile isEqualToString:@""]){ ABMultiValueRef ABphones = ABMultiValueCreateMutable(kABMultiStringPropertyType); if(![myContact.phone_business isEqualToString:@""]) ([myContact.phone_business stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]].length == 4 || [myContact.phone_business stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]].length == 5) ?

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
