Handle completionHandler

UIApplication *application = [UIApplication sharedApplication];
NSURL *URL = [NSURL URLWithString:@"http://www.google.com"];
[application openURL:URL options:@{} completionHandler:^(BOOL success) {
    if (success) {
         NSLog(@"Opened url");
    }
}];

Without handling completionHandler

[application openURL:URL options:@{} completionHandler:nil];
