objective c - imageWithContentsOfURL Check if image is valid -


i using following code obtain image url , display in uiimageview

how can check url passing has returned valid image? (i.e image exists?)

nsurl *imageurl = [nsurl urlwithstring:stringurl]; myimage.image = [uiimage imagewithcontentsofurl:imageurl];

this looks answered in: uiimageview-image-using-a-url

if not sufficient take @ nice asynchronous capabilities offered afnetworking.
