Question

这是我从设备访问联系人详细信息的代码。当我尝试在另一个类中使用ABRecordRef值时，它会在我的程序中崩溃，所以请帮我解决这个问题

在这里输入代码

CFArrayRef people = ABAddressBookCopyArrayOfAllPeople(addressBook);
            CFMutableArrayRef peopleMutable = CFArrayCreateMutableCopy(
                                                                       kCFAllocatorDefault,
                                                                       CFArrayGetCount(people),
                                                                       people
                                                                       );
            CFArraySortValues(
                              peopleMutable,
                              CFRangeMake(0, CFArrayGetCount(peopleMutable)),
                              (CFComparatorFunction) ABPersonComparePeopleByName,
                              (void*) ABPersonGetSortOrdering()
                              );

arrTemp1=(NSMutableArray *)CFBridgingRelease(peopleMutable);


for (int i=0;i<[arrTemp1 count];i++)
{
    allUsers = [[AllUsers alloc]init];
    allUsers.person=(__bridge ABRecordRef)(arrTemp1[i]);
}

@interface AllUsers : NSObject
@property (nonatomic,assign)  ABRecordRef  person;
@end

当我尝试访问另一个类中的person值时，它会转为崩溃

AllUsers *currentUser;
ABRecordRef  personImageRef = currentUser.person;
NSLog(@"image ref -- %@",currentUser.person);

请帮我解决这个问题...

请检查您所制作的商品是否assign将其设为strong并尝试告诉我们。

@property (nonatomic,readonly)  ABRecordRef  person;

如何在类中访问ABRecordRef值？
