我可以使用Jquery来查找元素并将它的CSS宽度设置为current-width-x？(Can I use Jquery to find an element and set it's CSS width to current-width - x?)

 问题出在我认为的这个问题上： 
 
let existingContact: ABRecord! = ABAddressBookGetPersonWithRecordID(adbk, recordID).takeRetainedValue()
 
 我改变了我的功能，现在它使用ABRecord而不是ABRecordID来访问所需的记录。 
 
 固定代码： 
 
if doesPersonExistWithFirstName(firstName: "Call Recorder", inAddressBook: adbk)
        {
            var success: Bool = false
            let phoneNumbers: ABMutableMultiValue = ABMultiValueCreateMutable(ABPropertyType(kABMultiStringPropertyType)).takeRetainedValue()
            var error: Unmanaged<CFError>? = nil

            success = ABMultiValueAddValueAndLabel(phoneNumbers, recordServicePhoneNumber!, kABPersonPhoneMainLabel, nil)
            print("setting phone number successful? \(success)")
            success = ABRecordSetValue(existingContact, kABPersonPhoneProperty, phoneNumbers, &error)
            print("adding phone numbers successful? \(success)")
            success = ABAddressBookAddRecord(adbk, existingContact, &error)
            print("Adbk addRecord successful? \(success)")
            success = ABAddressBookSave(adbk, &error)
            print("Adbk Save successful? \(success)")
        }
        else
        {
            let newContact: ABRecord! = ABPersonCreate().takeRetainedValue()
            var success: Bool = false
            let newFirstName: NSString = "Call Recorder"
            let image: UIImage = UIImage(named: "record")!
            let imageData = UIImagePNGRepresentation(image)
            let phoneNumbers: ABMutableMultiValue = ABMultiValueCreateMutable(ABPropertyType(kABMultiStringPropertyType)).takeRetainedValue()
            var error: Unmanaged<CFError>? = nil

            success = ABRecordSetValue(newContact, kABPersonFirstNameProperty, newFirstName as CFTypeRef, &error)
            print("setting first name was successful? \(success)")
            success = ABMultiValueAddValueAndLabel(phoneNumbers, recordServicePhoneNumber!, kABPersonPhoneMainLabel, nil)
            print("setting phone number successful? \(success)")
            success = ABPersonSetImageData(newContact, imageData as CFData!, &error)
            print("setting image successful? \(success)")
            success = ABRecordSetValue(newContact, kABPersonPhoneProperty, phoneNumbers, &error)
            print("adding phone numbers successful? \(success)")
            success = ABAddressBookAddRecord(adbk, newContact, &error)
            print("Adbk addRecord successful? \(success)")
            success = ABAddressBookSave(adbk, &error)
            print("Adbk Save successful? \(success)")
        }
 
 existingContacts实现： 
 
var existingContact: ABRecord! = ABPersonCreate().takeRetainedValue()
func doesPersonExistWithFirstName(firstName paramFirstName: String,
                                      inAddressBook addressBook: ABAddressBook) -> Bool
    {
        let people = ABAddressBookCopyArrayOfAllPeople(addressBook).takeRetainedValue() as NSArray as [ABRecord]
        for person: ABRecord in people
        {
            let firstName = ABRecordCopyValue(person, kABPersonFirstNameProperty).takeRetainedValue() as! String
            if firstName == paramFirstName
            {
                existingContact = person
                return true
            }
        }
        return false
    }

The problem was in this line as I thought:
 
let existingContact: ABRecord! = ABAddressBookGetPersonWithRecordID(adbk, recordID).takeRetainedValue()
 
I changed my function so now it uses ABRecord instead of ABRecordID to access required record.
 
Fixed code:
 
if doesPersonExistWithFirstName(firstName: "Call Recorder", inAddressBook: adbk)
        {
            var success: Bool = false
            let phoneNumbers: ABMutableMultiValue = ABMultiValueCreateMutable(ABPropertyType(kABMultiStringPropertyType)).takeRetainedValue()
            var error: Unmanaged<CFError>? = nil

            success = ABMultiValueAddValueAndLabel(phoneNumbers, recordServicePhoneNumber!, kABPersonPhoneMainLabel, nil)
            print("setting phone number successful? \(success)")
            success = ABRecordSetValue(existingContact, kABPersonPhoneProperty, phoneNumbers, &error)
            print("adding phone numbers successful? \(success)")
            success = ABAddressBookAddRecord(adbk, existingContact, &error)
            print("Adbk addRecord successful? \(success)")
            success = ABAddressBookSave(adbk, &error)
            print("Adbk Save successful? \(success)")
        }
        else
        {
            let newContact: ABRecord! = ABPersonCreate().takeRetainedValue()
            var success: Bool = false
            let newFirstName: NSString = "Call Recorder"
            let image: UIImage = UIImage(named: "record")!
            let imageData = UIImagePNGRepresentation(image)
            let phoneNumbers: ABMutableMultiValue = ABMultiValueCreateMutable(ABPropertyType(kABMultiStringPropertyType)).takeRetainedValue()
            var error: Unmanaged<CFError>? = nil

            success = ABRecordSetValue(newContact, kABPersonFirstNameProperty, newFirstName as CFTypeRef, &error)
            print("setting first name was successful? \(success)")
            success = ABMultiValueAddValueAndLabel(phoneNumbers, recordServicePhoneNumber!, kABPersonPhoneMainLabel, nil)
            print("setting phone number successful? \(success)")
            success = ABPersonSetImageData(newContact, imageData as CFData!, &error)
            print("setting image successful? \(success)")
            success = ABRecordSetValue(newContact, kABPersonPhoneProperty, phoneNumbers, &error)
            print("adding phone numbers successful? \(success)")
            success = ABAddressBookAddRecord(adbk, newContact, &error)
            print("Adbk addRecord successful? \(success)")
            success = ABAddressBookSave(adbk, &error)
            print("Adbk Save successful? \(success)")
        }
 
existingContacts implementation:
 
var existingContact: ABRecord! = ABPersonCreate().takeRetainedValue()
func doesPersonExistWithFirstName(firstName paramFirstName: String,
                                      inAddressBook addressBook: ABAddressBook) -> Bool
    {
        let people = ABAddressBookCopyArrayOfAllPeople(addressBook).takeRetainedValue() as NSArray as [ABRecord]
        for person: ABRecord in people
        {
            let firstName = ABRecordCopyValue(person, kABPersonFirstNameProperty).takeRetainedValue() as! String
            if firstName == paramFirstName
            {
                existingContact = person
                return true
            }
        }
        return false
    }
