How to set UIImageView value from a String in iPhone?

I am parsing a Remote XML file and storing the values in an NSArray. From the array I am using NSScanner to get a particular image and allotting it to UIImageView.

After scanning and getting the URL link of an image, I am assigning it to a UIImageView but it's not showing the image. I am getting only a blank white window. The code is shown below:

MyViewController

NSURL *url = [NSURL URLWithString:@"http://myXML.com/Category.xml"];
AGSParser *parser = [[AGSParser alloc] init];
if ([parser loadXMLByURL:url]){
   self.xmlProductsResults = parser.products;
   NSArray *myArray = [_xmlProductsResults objectAtIndex:0];
   NSString *string = [myArray description];
   NSString *url = nil;
   NSScanner *parser = [NSScanner scannerWithString:string];
  [parser scanUpToString:@"imageUrlString" intoString:nil];
  if (![parser isAtEnd]) {
     [parser scanUpToString:@"=" intoString:nil];
     NSCharacterSet *charset = [NSCharacterSet characterSetWithCharactersInString:@"\"'"];
    [parser scanUpToCharactersFromSet:charset intoString:nil];
    [parser scanCharactersFromSet:charset intoString:nil];
    [parser scanUpToCharactersFromSet:charset intoString:&url];
    NSLog(@"URL: %@",url);
 }
}

When I check in NSLog I am getting the string value as http://myimage.com/image1.png. After this in my View Controller I am assigning this image url to UIImageView like this:

UIImageView *myImageView = [[UIImageView alloc] init];
myImageView.image = [UIImage imageNamed:url];

Here the image is not assigned. Can anyone suggest me how to solve this?

Make [UIImage imageNamed:url] into [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:url]]].

Application windows are expected to have a root view controller at the end of application launch

this happens when have not given the root view controller that is starting window in your app delegate class.

self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
