我试图CNPostalAddress在Objective-C中创建一些字符串.我有街道地址,城市,州,邮编和国家/地区价值.我已经尝试了下面的代码,但它不起作用.谢谢你宝贵的时间.

CNPostalAddress *postalAddr = [[CNPostalAddress alloc] init];
postalAddr.street = [NSString stringWithFormat:@"%@ %@",street1,street2];// here, I am getting an error: Street property is read only.

我尝试了这个：

    let contact = CNMutableContact()
    contact.namePrefix = data["firstName"] as! String
    contact.nameSuffix = data["lastName"] as! String
    contact.organizationName = data["company"] as! String
    contact.jobTitle = data["jobTitle"] as! String

    let address = CNMutablePostalAddress()
    address.street = data["street"] as! String
    address.city = data["city"] as! String
    address.state = data["state"] as! String
    address.postalCode = data["zipcode"] as! String
    address.country = data["country"] as! String

    contact.postalAddresses = [address]

我收到此错误：

Cannot convert value of type 'CNMutablePostalAddress' to expected element type 'CNLabeledValue<CNPostalAddress>'

所以，我尝试了这个：

let contact = CNMutableContact()
    contact.namePrefix = data["firstName"] as! String
    contact.nameSuffix …

我想修改从a 的属性CNPostalAddress获得的a 的值。postalAddressCLPlacemark

由于CNPostalAddress具有不可变的属性，我想将其转换为CNMutablePostalAddress. 然而，似乎没有一种干净的方法可以做到这一点。我目前的方法是这样的：

extension CNPostalAddress {
    var mutableAddress: CNMutablePostalAddress {
        let address = CNMutablePostalAddress()

        address.city = city
        address.country = country
        address.postalCode = postalCode
        address.state = state
        address.street = street

        [...]

        return address
    }
}

有没有更好的方法来进行这种转换？
