解析iPhone应用内存泄露

Question

应用代码如下：
用来过滤和筛选

- (long)personRecord:(ABRecordRef)paramPerson{

    if(paramPerson == nil){

        NSLog(@"The given Person is Null");
    }

    ABMutableMultiValueRef emails = ABRecordCopyValue(paramPerson, kABPersonEmailProperty);
    if(emails == nil){

        return 0;
    }

    NSLog(@"%ld",ABMultiValueGetCount(emails));
    // return (ABMultiValueGetCount(emails));

    return (ABMultiValueGetCount(emails));
}

但是当解析的时候出现：

怎么解决这个Leak？

Answer 1

你是从ABRecordRef中获得了一份复制的object.释放一下

修改为如下方法：

- (long)personRecord:(ABRecordRef)paramPerson
  {

    if(paramPerson == nil)
    {

        NSLog(@"The given Person is Null");
    }

    ABMutableMultiValueRef emails = ABRecordCopyValue(paramPerson, kABPersonEmailProperty);
    if(emails == nil)
    {

        return 0;
    }

    NSLog(@"%ld",ABMultiValueGetCount(emails));
    // return (ABMultiValueGetCount(emails));

    long count = ABMultiValueGetCount(emails);
     CFRelease(emails);
     return count;
}
