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);
i am new on iphone apps.Now this is my first app,app is installed but not run?
I write this code it shows memory leak.please find out.Thanks in advance.

您在firstName 和lastName 上使用
ABRecordCopyValue，这意味着您还需要CFRelease这些。You are using
ABRecordCopyValueon firstName and lastName which means you need toCFReleasethose as well.CFRelease 是一种可行的方法（@Joe 和 @jamapag 已经回答了）.. 我想补充一点，XCode 有一些不错的功能，例如 cmd + shift + a 提供 ua 静态内存分析器.. 你也可以使用 run - >运行性能工具，然后使用分配或泄漏来动态分析我们的内存管理。
CFRelease is a way to go (as @Joe and @jamapag already answered).. I would just like to add that XCode has few nice features like cmd + shift + a gives u a static memory analyser.. And you can also use run -> run w/ performance tools and then use allocations or leaks to analyse our memory management dynamically.
