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

You can use + (id)URLWithString:(NSString *)URLString method of NSURL, which returns nil if the string is malformed.

Use if (URL && URL.scheme && URL.host) for checking URL.
