Question

我正在尝试创建一个新的联系人并将其添加到AddressBook但是当我到达ABAddressSave代码行时，我得到了EXC_BAD_ACCESS。我看不出我做错了什么，我启用NSZombie来检查这是否是与内存相关的错误，但它没有发现任何错误。谁能告诉我这段代码有什么问题？提前谢谢！

    CFErrorRef error = NULL;

 ABAddressBookRef iPhoneAddressBook = ABAddressBookCreate();

 ABRecordRef newRecord = ABPersonCreate();

 ABRecordSetValue(newRecord, kABPersonFirstNameProperty, @"Xxxxxx", &error);

 ABRecordSetValue(newRecord, kABPersonURLProperty,  @"Yyyyyy", &error);


 //Add phone numbers to record

 ABMutableMultiValueRef phones = ABMultiValueCreateMutable(kABMultiStringPropertyType);
 ABMultiValueAddValueAndLabel(phones, @"1-555-555-5555", kABWorkLabel, NULL);


 ABRecordSetValue(newRecord, kABPersonPhoneProperty, phones, &error);

 CFRelease(phones);

 //Add email address to record

 ABMutableMultiValueRef emails = ABMultiValueCreateMutable(kABMultiStringPropertyType);
 ABMultiValueAddValueAndLabel(emails, @"xxx_xxx@yahoo.com", kABWorkLabel, NULL);


 ABRecordSetValue(newRecord, kABPersonEmailProperty, emails, &error);

 CFRelease(emails);

 ABMutableMultiValueRef multiAddress = ABMultiValueCreateMutable(kABMultiDictionaryPropertyType);

 NSMutableDictionary *addressDict = [[NSMutableDictionary alloc] init];

 [addressDict setObject:@"xxx1" forKey:(NSString *)kABPersonAddressStreetKey];
 [addressDict setObject:@"xxx2" forKey:(NSString *)kABPersonAddressCityKey];
 [addressDict setObject:@"xxx3" forKey:(NSString *)kABPersonAddressStateKey];
 [addressDict setObject:@"xxx4" forKey:(NSString *)kABPersonAddressZIPKey];

 ABMultiValueAddValueAndLabel(multiAddress, addressDict,  kABWorkLabel, NULL);


 ABRecordSetValue(newRecord, kABPersonAddressProperty, multiAddress, &error);

 CFRelease(multiAddress);
 [addressDict release];


 ABAddressBookAddRecord(iPhoneAddressBook, newRecord, &error);
 ABAddressBookSave(iPhoneAddressBook, NULL);

 if(error != nil){
  NSLog(@"Error creating contact:%@", error);
 }

Answer 1

我建议使用Memory-＆gt; Object Allocations模板在Instruments中运行代码。它应该很快向您显示哪个对象是问题以及导致问题的内存释放。

好的我已经弄清楚了，这不是内存问题，实际上错误甚至不在发布的代码中，因为当我发布代码时我清理了一点而且错误它不再存在了。有点傻但我做到了。所以错误：当我分配一个URL值时，我给它分配了一个简单的ABRecordSetValue调用，我应该使用ABMutableMultiValueRef。此外，每当我用nil值填充记录时，我遇到了崩溃，所以我认为在构建Person对象时不允许使用nil值。谢谢你的时间！

执行ABAddressBookSave时EXC_BAD_ACCESS！
