Question

I’ve been trying to display some images from the web in a UIWebView. What I’ve been doing is directly using the loadRequest: method on the URL, with ScalesToFit = YES and AspectFit mode to make it fit the WebView frame. This works fine on iOS5, but in iOS4 it doesn’t. In iOS4 the image appears zoomed out.

Here’s a screenshot of it in iOS5

And what I get in iOS4

From what I read, iOS5 comes with an integrated ScrollView, and iOS4 and earlier versions don’t. Is it because of that? If it is, how can I accomplish what I’m trying to do? I’ve tried placing the UIWebView inside a UIScrollView and setting the scalesToFit and AspectView settings, but I’m still getting the same results.

Why not just download the image first? I wrote this function for doing just that:

-(void)loadImageFromURL:(NSString*)url{
    [delegate didBeginLoadingFromURL:url];

    NSData * imageData = [[NSData dataWithContentsOfURL:[NSURL URLWithString:url]] retain];
    UIImage *image = [[UIImage alloc] initWithData:imageData];  

    if (delegate && [delegate respondsToSelector:@selector(didRecieveImage:FromURL:)]) { //Make sure the delegage still exists and what not ;)
             [delegate didRecieveImage:image FromURL:url];
    }

    [imageData release];
    [image release];

}
