问题 I have a system which is using phone numbers as unique identifiers. For this reason, I want to format all phone numbers as they come in using a normalized format. Because I have no control over my source data, I need to parse out these numbers myself and format them before adding them to my DB. I'm about to write a parser that can read phone numbers in and output a normalized phone format, but before I do I was wondering if anyone knew of any pre-existing libraries I could use to format phone

问题 At present, the options on the Firebase website limit you to prepackaged solutions for authenticating users through Facebook or a person's email, etc. I wish to allow user to login and authenticate using their cell phone number, much like Snapchat allows. Is there a pre-packaged solution for this? How can this be built out? 回答1: That is currently not supported. Phone number auth is a tricky feature to implement from a privacy, security and product perspective. That said, if you wish to build

问题 I'm having a problem with extracting phone numbers of some people in my contact list. First I show all the contacts in a listview: String[] projection = new String[] { ContactsContract.Contacts._ID, ContactsContract.CommonDataKinds.Phone.CONTACT_ID, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME, ContactsContract.CommonDataKinds.Phone.NUMBER }; mCursor = mContext.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, projection, ContactsContract.CommonDataKinds

问题 Telephone number should be international and user has to enter the complete phone number with country code. For that I need a regex for formatting the phone number. 回答1: For real regex testing use RegexKitLite. As for the regular expression itself, something like this (from Validate Phone Numbers: A Detailed Guide) should work: ^\+(?:[0-9] ?){6,14}[0-9]$ Note that when you specify it in your code you need to escape the backslash character (\), so it would look like this: NSString *regexString

问题 I have a table which is full of arbitrarily formatted phone numbers, like this 027 123 5644 021 393-5593 (07) 123 456 042123456 I need to search for a phone number in a similarly arbitrary format ( e.g. 07123456 should find the entry (07) 123 456 The way I'd do this in a normal programming language is to strip all the non-digit characters out of the 'needle', then go through each number in the haystack, strip all non-digit characters out of it, then compare against the needle, eg (in ruby)
