从 SWIFT 中的 iPhone 获取联系人号码时应用程序崩溃

Question

我正在尝试使用以下代码获取联系人：

var addressBook: ABAddressBook!
let addressBookRef: ABAddressBook = ABAddressBookCreateWithOptions(nil, nil).takeRetainedValue()

var arrContacts = [""]
var personNameContactNo:[String: String] = ["":""]
var arrOfDictContacts = NSMutableArray()
var Name: String!

    if let people = ABAddressBookCopyArrayOfAllPeople(addressBook)?.takeRetainedValue() as? NSArray {

        for person in people{
            if let name = ABRecordCopyValue(person, kABPersonFirstNameProperty).takeRetainedValue() as? String {
                Name = name
            }
            let numbers:ABMultiValue = ABRecordCopyValue(
                person, kABPersonPhoneProperty).takeRetainedValue()
            var number = ABMultiValueCopyValueAtIndex(numbers,0).takeRetainedValue() as! String

            println("number = \(number)")

            if(number.isEmpty) {
                println("empty")
            } else {
                personNameContactNo.removeAll(keepCapacity: true)
                personNameContactNo.updateValue(number, forKey:Name)
                arrOfDictContacts.addObject(personNameContactNo)
            }
            println(personNameContactNo)
        }
        println(arrOfDictContacts)
    }

what am expecting is: ["Arun":"123455"], ["John":"23456122"], etc...

它在模拟器中运行良好，但在设备上运行不佳。也许是由于一些零值。该应用程序崩溃并显示以下消息：fatal error: unexpectedly found nil while unwrapping an Optional value (lldb)

尝试；这应该可以解决您的问题。

var addressBookRef: ABAddressBookRef = ABAddressBookCreateWithOptions(nil, nil).takeRetainedValue()

var arrOfDictContacts:NSMutableArray = NSMutableArray()

let people:NSArray = ABAddressBookCopyArrayOfAllPeople(addressBookRef).takeRetainedValue();

for person in people{
        if  let name:String = ABRecordCopyValue(person, kABPersonFirstNameProperty)?.takeRetainedValue() as? String {
            let numbers:ABMultiValue = ABRecordCopyValue(person, kABPersonPhoneProperty).takeRetainedValue()

//                if (ABMultiValueGetCount(numbers) > 0) {  //This condition is optional because using '?' before calling takeRetainedValue
                if let number:String = ABMultiValueCopyValueAtIndex(numbers,0)?.takeRetainedValue() as? String {
                    println("number = \(number)");
                    arrOfDictContacts.addObject(["\(name)":"\(number)"]);
                }
//                }
        }
}
//--
println(arrOfDictContacts);
