IOS IBAction button not going to website using URL

Question

i have a button on a view controller and i want to click the button and it goes to a web site. the website is held on parse.com.

the code as follows

- (IBAction)WebAddressBtn:(id)sender {
    NSString *url = [self.exam objectForKey:@"Website"];
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:url]];
    NSLog(@"website: %@",url);
}

the NSLog shows Null for the value url

but the data is held at

self.exam objectForKey:@"Website"

NSLog confirms its there

this works and will go to google

- (IBAction)WebAddressBtn:(id)sender {


    NSString *url = @"http://www.google.com";
    //[self.exam objectForKey:@"Website"];
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:url]];
    NSLog(@"website: %@",url);


}

if i try

NSURL *url = [self.exam objectForKey:@"Website"];

url is still showing as Null but i know the data is in self.exam objectForKey:@"Website

NSLog Output for data

    name = "DMK Media & Photography Ltd";
    phone1 = 01993835148;
    phone2 = 07795966848;
    postcode = "OX28 4BT";
    products = "<PFRelation: 0x10dc75320>(<00000000 00000000>.(null) -> products)";
    website = "http://www.dmkmedia.co.uk";

Answer 1

[UIApplication sharedApplication] openURL wont work properly if it doesnot have properly formatted url. Please check whether your url has "http://"
