a开发者_JAVA百科nnotationView.image = resizedImage;
annotationView.opaque = NO;
UIImageView *sfIconView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"here the image URL"]];

imageNamed takes a file from your local application bundle.

You want:

UIImageView *sfIconView = [[UIImageView alloc] initWithImage:[UIImage imageWithData:[NSData dataWithContentsOfURL:@"here is the image URL"]]];

I don't recommend doing it this way though because it'll block the main UI thread. You should consider loading the image data for your pin asynchronously first.
