How to get phone number from string? - objective-c

Question

I want to extract the phone number from a NSString.
For ex: In the string Nandu # [phone], I want to extract [phone].
I have tried code like,
NSString *myString = #"Nandu # [phone]";
NSString *myRegex = #"\\d{2}+\\d{3}-\\d{3}-\\d{4}";
NSRange range = [myString rangeOfString:myRegex options:NSRegularExpressionSearch];
NSString *phoneNumber = nil;
if (range.location != NSNotFound) {
phoneNumber = [myString substringWithRange:range];
NSLog(#"%#", phoneNumber);
} else {
NSLog(#"No phone number found");
}
how can I get phone number with +91 also.

Answer 1

You can use this Regex pattern
(\+\d{2}-\(\d{3}\)-\d{3}-\d{4})

Answer 2

Using NSCharacterSet you can get your output. see below code and let me know if you have any query then.
NSString *originalString = #"Nandu # [phone]";
NSString *cleanedString = [[originalString componentsSeparatedByCharactersInSet:[[NSCharacterSet characterSetWithCharactersInString:#"0123456789-+()"] invertedSet]] componentsJoinedByString:#""];
NSLog(#"%#", cleanedString); //[phone]

You can use componentsSeparatedByString
NSString *originalString = #"Nandu # [phone]";
NSArray *arrayWithTwoStrings = [originalString componentsSeparatedByString:#"+"];
NSString *mobileNumberstring = [NSString stringWithFormat:#"+%#",[arrayWithTwoStrings objectAtIndex:1]];
NSLog (#"%#",mobileNumberstring);
