内存泄漏使用AddressBook：泄漏对象“ABStyleProvider”

我无法正常访问我的联系人的地址属性。我能够使用下面的方法成功访问电话号码或地址，但是当获取地址属性时，我会在负责框架处发生泄漏，并显示“+ [ABStyleProvider]”。任何人都可以告诉我这是什么意思或我做错了什么？内存泄漏使用AddressBook：泄漏对象“ABStyleProvider”

下面是ABPeoplePickerNavigationController。以下是我如何处理电话号码或地址的选择。我使用NSMutableString和CFDictionaryGetValueIfPresent来仅收集非空数据并将其作为字符串返回。

感谢您的帮助和任何建议，将不胜感激。

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]; 
} 
} 
}

作为后续，我完全删除所有代码，只是显示，并在下列情况下，驳回了peoplePickerController： 1.如果一个人选择 2.如果属性选择 3.如果用户取消并在每种情况下，我看到上述内存泄漏。

仪器扩展详细泄漏：（16字节）。每次回到我的主视图都会泄漏？

除了这里是我的PeoplePicker初始化和从IBAction为方法

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];

作为一个后续，我完全删除了所有这些代码，只是在以下情况下显示和解除了peoplePickerController： – user582546 2011-01-21 07:59:15
