Question

我有一个自定义键盘，我想在当前活动的EditText中插入符号⏺。我用这个：

func contactDetail () {

    var myPhValue:NSString!
    var myPBfirstname:NSString!

    let qualityOfServiceClass = QOS_CLASS_BACKGROUND
    let backgroundQueue = dispatch_get_global_queue(qualityOfServiceClass, 0)
    dispatch_async(backgroundQueue,  {
        let addressBook : ABAddressBookRef? = ABAddressBookCreateWithOptions(nil, nil).takeRetainedValue()
        ABAddressBookRequestAccessWithCompletion(addressBook, { (granted : Bool, error: CFError!) -> Void in
            if granted == true {
                let allContacts : NSArray = ABAddressBookCopyArrayOfAllPeople(addressBook).takeRetainedValue()
                for contactRef:ABRecordRef in allContacts { // first name
                    myPBfirstname = ABRecordCopyValue(contactRef, kABPersonFirstNameProperty)?.takeRetainedValue() as! NSString? ?? ""
                    let myPBlastname = ABRecordCopyValue(contactRef, kABPersonLastNameProperty)?.takeRetainedValue() as! NSString? ?? ""
                    let phonesRef: ABMultiValueRef = ABRecordCopyValue(contactRef, kABPersonPhoneProperty)?.takeRetainedValue() as ABMultiValueRef? ?? ""
                    var phonesArray  = Array<Dictionary<String,String>>()
                    for var i:Int = 0; i < ABMultiValueGetCount(phonesRef); i++ {
                        let myPhLabel = ABMultiValueCopyLabelAtIndex(phonesRef, i)?.takeRetainedValue() as NSString? ?? ""
                        myPhValue = ABMultiValueCopyValueAtIndex(phonesRef, i)?.takeRetainedValue() as! NSString? ?? ""
                        if myPhLabel.containsString("Mobile") {

                        }
                    }
                    let nameString = " "+(myPBlastname as String)
                    let nameValues = (myPBfirstname as String)+(nameString as String)
                    let contactDict : Dictionary = ["name": nameValues,"phone":myPhValue]
                    self.contactArray.addObject(contactDict)

                    if self.contactArray.count == 0 {
                        NSLog("contactValue is Zero")
                    }
                    else{
                        NSLog("count Value %d", self.contactArray.count)
                    }

                }


            }

            dispatch_async(dispatch_get_main_queue(), { () -> Void in

                self.contactTable.hidden = false
                self.contactTable.reloadData()


            })
        })
    })

}



func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
 return contactArray.count
}


func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{
     let cell:UITableViewCell = self.contactTable.dequeueReusableCellWithIdentifier("cell") as UITableViewCell!
    cell.selectionStyle = UITableViewCellSelectionStyle.None

    cell.preservesSuperviewLayoutMargins = false
    cell.separatorInset = UIEdgeInsetsZero
    cell.layoutMargins = UIEdgeInsetsZero



    cell.textLabel!.text = contactArray.valueForKey("name").objectAtIndex(indexPath.row) as? String

    return cell

}

但是这只插入一个空格（没有可见的字符）。我认为Android不支持所有unicode字符，但是有没有办法插入这个符号？

为什么不在java代码中尝试以下两个选项：

editText.setText("\u23FA");

或

editText.getText().append("\u23FA");

让我知道你是怎么做到的？
