找出内存泄漏吗？

我是 iphone 应用程序的新手。现在这是我的第一个应用程序，应用程序已安装但未运行？ 我写的这段代码显示内存泄漏。请找出来。提前致谢。

ABRecordRef ref = CFArrayGetValueAtIndex(all, i);

CFStringRef *firstName = (CFStringRef *)ABRecordCopyValue(ref, kABPersonFirstNameProperty);
NSLog(@"Name %@", firstName);
contact.strFirstName = (NSString*)firstName;

CFStringRef *lastName = (CFStringRef *)ABRecordCopyValue(ref, kABPersonLastNameProperty);
NSLog(@"Name %@", lastName);
contact.strLastName = (NSString*)lastName;
contact.contactName = [NSString stringWithFormat:@"%@ %@",(NSString *)firstName,lastName];
NSLog(@"Name %@", contact.contactName);

ABMutableMultiValueRef phoneNumbers = ABRecordCopyValue(ref, kABPersonPhoneProperty);
for(CFIndex j = 0; j < ABMultiValueGetCount(phoneNumbers); j++)
{
    CFStringRef phoneNumberRef = ABMultiValueCopyValueAtIndex(phoneNumbers, j);

    NSString *phoneNumber = (NSString *) phoneNumberRef;
    contact.strMobileNo = phoneNumber;
    NSLog(@"phoneNO is %@", phoneNumber);

    CFRelease(phoneNumberRef);

}       

ABMultiValueRef emails = ABRecordCopyValue(ref, kABPersonEmailProperty);
for(CFIndex k = 0; k < ABMultiValueGetCount(emails); k++)
{
    CFStringRef emailRef = ABMultiValueCopyValueAtIndex(emails, k);
    NSString *mailid = (NSString *) emailRef;
    contact.strMail = mailid;
    NSLog(@"Email is %@", mailid);

    CFRelease(emailRef);

}

CFRelease(emails);
CFRelease(phoneNumbers);

您正在使用ABRecordCopyValue在名字和姓氏上，这意味着你需要CFRelease那些也是如此。
