or any other formats with country code and area code etc..

Answer 1

如果您尝试过这种方法，那么它将有所帮助，但不确定，

NSString *str=[PhoneNumber substringToIndex:[PhoneNumber length]-10];

Answer 2

Taking a look at the amount of different prefixes you can have List of country calling codes [wikipedia] and Internatioal dialing prefix [wikipedia], one could reach the conclusion that without narrowing the area down you'll probably not get very far with this.

If however you'll be handling phone numbers from a specific region to another specific region you might be able to come up with something.
