Question

如何获取保存在联系人中的所有组名？以下是我的代码供您参考：

NSMutableArray *list = [NSMutableArray array];
ABAddressBookRef myAddressBook = ABAddressBookCreate();
CFArrayRef allSources = ABAddressBookCopyArrayOfAllGroups(myAddressBook);

list = [NSMutableArray arrayWithArray: (__bridge NSArray*) allSources];

NSLog(@"GROUPS %@",[list objectAtIndex:0]);

NSLog返回a但我需要自己获取组名。

感谢。

使用ABRecordCopyCompositeName()功能。

ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL);
if (addressBook != NULL) {
    ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {
        if (granted) {
            CFArrayRef allGroups = ABAddressBookCopyArrayOfAllGroups(addressBook);
            if (allGroups != NULL) {
                NSMutableArray *names = [NSMutableArray array];
                for (int i = 0; i < CFArrayGetCount(allGroups); i++) {
                    ABRecordRef group = CFArrayGetValueAtIndex(allGroups, i);
                    CFStringRef name = ABRecordCopyCompositeName(group);
                    [names addObject:(__bridge NSString *)name];
                    CFRelease(name);
                }
                NSLog(@"names = %@", names);
                CFRelease(allGroups);
            }
        }
        CFRelease(addressBook);
    });
}

这对我有用：


    Error:(36, 102) type mismatch;
     found   : T
     required: String
        def +(that: Vector[T]): Vector[T] = new VectorImpl[T](_data.zip(that).map(elem => elem._1 + elem._2))
                                                                         ^   
    Error:(37, 95) value - is not a member of type parameter T
        def -(that: Vector[T]): Vector[T] = new VectorImpl[T](_data.zip(that).map(elem => elem._1 - elem._2))
                                                                         ^
