內存泄漏使用AddressBook：泄漏對象「ABStyleProvider」

我無法正常訪問我的聯繫人的地址屬性。我能夠使用下面的方法成功訪問電話號碼或地址，但是當獲取地址屬性時，我會在負責框架處發生泄漏，並顯示「+ [ABStyleProvider]」。任何人都可以告訴我這是什麼意思或我做錯了什麼？內存泄漏使用AddressBook：泄漏對象「ABStyleProvider」

下面是ABPeoplePickerNavigationController。以下是我如何處理電話號碼或地址的選擇。我使用NSMutableString和CFDictionaryGetValueIfPresent來僅收集非空數據並將其作爲字符串返回。

感謝您的幫助和任何建議，將不勝感激。

if (person) { 
if (property == kABPersonPhoneProperty){ 
ABMultiValueRef phones = ABRecordCopyValue(person, kABPersonPhoneProperty); //Dane 

if (phones) { 

CFIndex index = ABMultiValueGetIndexForIdentifier(phones, identifier); 
NSString *phone = (NSString*)ABMultiValueCopyValueAtIndex(phones, index); 

//Set textField with Phone Number 
MyTextField.text = phone; 
[phone release]; 
CFRelease(phones); 

[self doneEnteringPhoneNumber]; 
} 

} 
else if (property == kABPersonAddressProperty){ 
ABMultiValueRef addresses = ABRecordCopyValue(person, kABPersonAddressProperty); //Dane 

if (addresses) { 
CFIndex index = ABMultiValueGetIndexForIdentifier(addresses, identifier); 
CFDictionaryRef dict = ABMultiValueCopyValueAtIndex(addresses, index); 

//Get Only valid address values (Non-Null) 
CFTypeRef aString; 
NSMutableString * address = [NSMutableString string]; 

if (CFDictionaryGetValueIfPresent(dict, kABPersonAddressStreetKey, &aString)){ 
[address appendString:[NSString stringWithFormat:@"%@ ",(NSString *)aString]]; 
} 
if (CFDictionaryGetValueIfPresent(dict, kABPersonAddressCityKey, &aString)){ 
[address appendString:[NSString stringWithFormat:@"%@ ",(NSString *)aString]]; 
} 
if (CFDictionaryGetValueIfPresent(dict, kABPersonAddressStateKey, &aString)){ 
[address appendString:[NSString stringWithFormat:@"%@ ",(NSString *)aString]]; 
} 
if (CFDictionaryGetValueIfPresent(dict, kABPersonAddressZIPKey, &aString)){ 
[address appendString:[NSString stringWithFormat:@"%@ ",(NSString *)aString]]; 
} 

CFRelease(dict); 

//Set Address 
DestinationTextField.text = address; 

CFRelease(addresses); 

//Auto trigger search for address 
[self doneEnteringAddress]; 
} 
} 
}

作爲後續，我完全刪除所有代碼，只是顯示，並在下列情況下，駁回了peoplePickerController： 1.如果一個人選擇 2.如果屬性選擇 3.如果用戶取消並在每種情況下，我看到上述內存泄漏。

除了這裏是我的PeoplePicker初始化和從IBAction爲方法

ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init]; 
picker.peoplePickerDelegate = self; 
NSArray * displayedProperties = [NSArray arrayWithObjects: 
           [NSNumber numberWithInt:kABPersonPhoneProperty], 
           [NSNumber numberWithInt:kABPersonAddressProperty], 
           nil]; 
picker.displayedProperties = displayedProperties; 
//Dane - here 
[self presentModalViewController:picker animated:YES]; 
[picker release];

作爲一個後續，我完全刪除了所有這些代碼，只是在以下情況下顯示和解除了peoplePickerController： – user582546 2011-01-21 07:59:15
