Question

My question is how can I get an email address if my UIWebView is loaded…

First I made a string about the View and I could find @ in my string with this:

NSString *myText = [mWebView stringByEvaluatingJavaScriptFromString:@"document.documentElement.textContent"];
if ([myText rangeOfString:@"@"].location == NSNotFound) {
    NSLog(@"Couldn't find mail address!");

}

else {
    NSLog(@"There is a valid mail address!");
}

But I don’t know how to get the content around this ( @) to a var.

try this.

NSString *myText = [www stringByEvaluatingJavaScriptFromString:@"document.body.innerHTML;"];
NSString *expression = @"[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}";
NSError *error = NULL;

NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:expression options:NSRegularExpressionCaseInsensitive error:&error];

NSTextCheckingResult *match = [regex firstMatchInString:myText options:0 range:NSMakeRange(0, [myText length])];

if (match){
    NSString *email = [myText substringWithRange:match.range];
    NSLog(@"There is a valid mail address: %@", email);
}else{
    NSLog(@"Couldn't find mail address!");
}
