URL Validation (Objective-C)

Question

I am trying to validate a URL with this method:

Code:

- (BOOL) validateUrl: (NSString *) candidate {

    NSString *urlRegEx=
    @\"((https?|ftp|gop         


        

Answer 1

What about using the following:

NSURL * url = [NSURL URLWithString:@"http://www.google.com"];

BOOL isValid = [UIApplication.sharedApplication canOpenURL:url];

note: best practice is to use regex
