I have an openweathermap API issue with iOS app

Question

I am using openweathermap API in my iOS app.

Below is my URL which I am calling to get weather info.

http://api.openweathermap.org/data/2.5/weather?lat=21.282778&lon=-157.829444&APPID=MYAPPID&lang=en-US

When I open this URL in a browser I get a proper response.

But when I call the web service from my iOS app, I do not get a response.

I get the following error:

{
    cod = 401;
    message = "Invalid API key. Please see http://openweathermap.org/faq#error401 for more info.";
}

I had created an API key from this URL: Create API key on Open Wheather

NSURL *URL = [NSURL URLWithString:@"http://api.openweathermap.org/data/2.5/weather?q=London,uk&appid=b1b15e88fa797225412429c1c50c122a&lang=en-US"];
    NSURLRequest *request = [NSURLRequest requestWithURL:URL];

    NSURLSession *session = [NSURLSession sharedSession];
    NSURLSessionDataTask *task = [session dataTaskWithRequest:request
                                            completionHandler:^(NSData *data, NSURLResponse *response, NSError *error)
    {
        NSError* errorObj;
        NSDictionary* json = [NSJSONSerialization
                              JSONObjectWithData:data
                              options:kNilOptions
                              error:&errorObj];

        NSLog(@" response is %@",json);

    }];

    [task resume];

You app id should be valid. I have hardcoded the url for demonstration.
