Validating the phone numbers - iphone

Question

I want to have only 13 numeric values or the 13numeric values can be prefixed with "+" sysmbol.so the + is not mandatory
Example : 1234567891234
another example is : [phone]
Telephone number format should be international,Is there any Regex for phone number validation in iPhone
I have tried the above link , but this +1234545 but i want to have only 13 numarals or + can be prefixed with that 13 numerals.
Please let me know , what can i change it here
This is the code i tried
NSString * forNumeric = #"^\\+(?:[0-9] ?){6,14}[0-9]$";
BOOL isMatch = [[textFieldRounded text] isMatchedByRegex:forNumeric];
if (isMatch == YES){
NSLog(#"Matched");
}
else {
NSLog(#"Not matched");
}

Answer 1

NSString * regex = #"((07|00447|004407|\\+4407|\\+447)\\d{9})";
Having found the leading 0 or the leading +44 once, why search for it again?
Basic simplification leads to
NSString * regex = #"((07|00440?7|\\+440?7)\\d{9})";
then to
NSString * regex = #"((07|(00|\\+)440?7)\\d{9})";
then to
NSString * regex = #"((0|(00|\\+)440?)7\\d{9})";
but 00 isn't the only common dial prefix, 011 is used in the US and Canada.
Adding that, and turning the order round, gives:
NSString * regex = #"(^((0(0|11)|\\+)440?|0)7\\d{9}$)";
or preferably
NSString * regex = #"(^(?:(?:0(?:0|11)|\\+)(44)0?|0)(7\\d{9}$))";
allowing 00447, 011447, +447, 004407, 0114407, +4407, 07 at the beginning, and with non-capturing groups.
For wider input format matching, allowing various punctuation (hyphens, brackets, spaces) use
NSString * regex = #"(^\\(?(?:(?:0(?:0|11)\\)?[\\s-]?\\(?|\\+)(44)\\)?[\\s-]?\\(?(?:0\\)?[\\s-]?\\(?)?|0)(7\\d{9})$)";
Extract the 44 country code in $1 (null if number entered as 07...) and the 10-digit NSN in $2.
However, be aware that numbers beginning 070 and 076 (apart from 07624) are NOT mobile numbers.
The final pattern:
NSString * regex = #"(^\\(?(?:(?:0(?:0|11)\\)?[\\s-]?\\(?|\\+)(44)\\)?[\\s-]?\\(?(?:0\\)?[\\s-]?\\(?)?|0)(7([1-5789]\\d{2}|624)\\)?[\\s-]?\\d{6}))$)";
Extract the NSN in $2 then remove all non-digits from it for further processing.

Answer 2

^(\+?)(\d{13})$ should do the trick, escape the slashes for objective-C usage.
13 digits, with an options + prefix.
If you want to play with regexp expressions you can use services like this one for visual feedback, very handy.
NSString * forNumeric = #"^(\\+?)(\\d{13})$";

Answer 3

How about this?
NSString *forNumeric = #"\\+?[0-9]{6,13}";
NSPredicate *predicate;
predicate = [NSPredicate predicateWithFormat:#"self matches %#", forNumeric];
BOOL isMatch = [predicate evaluateWithObject:#"[phone]"];
if (isMatch) NSLog(#"Matched");
else NSLog(#"Not matched");

Answer 4

NSDataDetector *matchdetector = [NSDataDetector dataDetectorWithTypes:NSTextCheckingTypePhoneNumber
error:&error];
NSUInteger matchNumber = [matchdetector numberOfMatchesInString:string options:0 range:NSMakeRange(0, [string length])];
If you use UITextField then:
textField.dataDetectorTypes = UIDataDetectorTypePhoneNumber;

Answer 5

you could try using a NSDataDetector:

available in iOS4+

Answer 6

The following is what I do for validating UK mobile numbers:
- (BOOL) isValidPhoneNumber
{
NSString * regex = #"((07|00447|004407|\\+4407|\\+447)\\d{9})";
NSPredicate *testPredicate = [NSPredicate predicateWithFormat:#"SELF MATCHES %#", regex];
BOOL validationResult = [testPredicate evaluateWithObject: self];
return validationResult;
}
