Create UIView and work with UIImage

First Create UIView by following Coding

UIView *uview = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 600, 600)];

[viewControl addSubview:uview];

Now to load the Image from External source is as follow:

   NSURL * imageURL = [NSURL URLWithString:@"http://ww.url.com/imageName.jpg"];

    NSData * imageData = [NSData dataWithContentsOfURL:imageURL];

    UIImage * image = [UIImage imageWithData:imageData];

    UIImageView *block = [[UIImageView alloc] initWithImage:image];

    block.frame = CGRectMake(10, 10, 200, 200);

    [uview addSubview:block];

    block = nil;

    uview = nil;

    image = nil;

    imageData = nil;

    imageURL = nil;

    

I have used ARC - Automatic Reference counting. So didn't released the variable here.
