在目标C中保存CNPostalAddress

Question

我有这样的代码：

CNMutablePostalAddress *postalAddress = [[CNMutablePostalAddress alloc] init];
[postalAddress setCity:@"City"];

CNLabeledValue *city = [CNLabeledValue labeledValueWithLabel:CNPostalAddressCityKey value:postalAddress.city];

NSArray<CNLabeledValue<CNMutablePostalAddress *> *> *postalAddresses = @[city];

contact.postalAddresses = @[postalAddresses];

我不知道如何进行这种转换，因为我需要在代码中将一个数组传递给contact.postalAddress。我试过一切可能的方法，但一无所获。

这段代码给了我一个例外：

*** Terminating app due to uncaught exception 'CNPropertyInvalidTypeException', reason: 'Labeled value (
"<CNLabeledValue: 0x12d5a14c0: identifier=080A5D1B-1F2D-4EE2-AB6F-BFAD523DA1C9, label=city, value=City>") has incorrect type __NSArrayI for key postalAddresses. It should be CNLabeledValue.'

我怎么能这么做？

Answer 1

这将创建一个新的邮政地址并将其添加到contact中。这就是你想要的，对吧？

CNMutablePostalAddress *postalAddress = [[CNMutablePostalAddress alloc] init];
postalAddress.city = @"City";

CNLabeledValue *labeledValue = [CNLabeledValue labeledValueWithLabel:CNLabelHome value:address];
contact.postalAddresses = @[labeledValue];

Answer 2

这是正确的实现。

CNMutablePostalAddress *postalAddress = [[CNMutablePostalAddress alloc] init];
postalAddress.street = @"1 Market Street";
postalAddress.city = @"Sydney";
postalAddress.postalCode = @"2000";
postalAddress.state = @"NSW";
CNLabeledValue *address = [CNLabeledValue labeledValueWithLabel:CNLabelWork value:postalAddress];
contact.postalAddresses = @[address];
