URL Validation Problem!

hello guys,

i am trying to validate URL with this method:

Code:

- (BOOL) validateUrl: (NSString *) candidate {
	
	NSString *urlRegEx=
	@"((https?|ftp|gopher|telnet|file|notes|ms-help):((//)|(\\\\))+[\w\d:#@%/;$()~_?\+-=\\\.&]*)";
    
	NSPredicate *urlTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", urlRegEx]; 
    return [urlTest evaluateWithObject:candidate];
	
}

it does not function! i think problem is with Regular expression !

 

Code:

((https?|ftp|gopher|telnet|file|notes|ms-help):((//)|(\\\\\\\\))+[\w\d:#@%/;$()~_?\\+-=\\\\\\.&]*)

i am using this now according to what you said, but still it does not work!

 

thank you my friend it already works
