and this is the method that seems to generate it:
-(BOOL) personViewController:(ABPersonViewController *)personViewController shouldPerformDefaultActionForPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier{
if (property == kABPersonPhoneProperty){
NSString *number = nil;
ABMultiValueRef phoneNumbers = ABRecordCopyValue(person, property);
if (ABMultiValueGetCount(phoneNumbers) > 0) {
number = (__bridge_transfer NSString*)ABMultiValueCopyValueAtIndex(phoneNumbers, identifier);
[self setInfoForPersonToCall:person];
self.numberToSave = number;
self.numberToCall = number;
if (self.shouldSendSMS) {
[self prepareToSMSNumber];
} else {
[self prepareToCallNumber];
}
}
if (phoneNumbers != nil)
CFRelease(phoneNumbers);
}
return NO;
}
Does anybody know how to fix it? I believe there is an issue with ARC memory management and with __bridge_transfer. thanks
Try iterating thru a contact's phone numbers (the kABPersonPhoneProperty multivalue), using CFBridgingRelease:
// Access the person's phone numbers (an ABMultiValueRef)
ABMultiValueRef phoneProperty = ABRecordCopyValue(person, kABPersonPhoneProperty);
if (phoneProperty)
{
// Iterate through the phone multivalue
for (CFIndex index = 0; index < ABMultiValueGetCount(phoneProperty); index++)
{
// Get the phone identifier for this phone property
ABMultiValueIdentifier phoneIdentifier = ABMultiValueGetIdentifierAtIndex(phoneProperty, index);
// Get the phone number
NSString *phoneNumber = CFBridgingRelease(ABMultiValueCopyValueAtIndex(phoneProperty, index));
}
}
