Yes a few ways but some of which are buggy. If you don't care about userinteraction at all you can just disabled it. Then they will only be able to zoom and move around the page (but not click any links or anything).

-(void)removeInput{
    UIScrollView *webViewContentView;
    for (UIView *checkView in [webView subviews] ) {
    if ([checkView isKindOfClass:[UIScrollView class]]) {
        webViewContentView = (UIScrollView*)checkView;
            break;
        }
    }

    for (UIView *checkView in [webViewContentView subviews] ) {
        checkView.userInteractionEnabled = NO;
    }
}

UIWebView without Copy/Paste and selection rectangle when showing documents

However that causes all userInteraction to be disabled which might not be what you want? To JUST disable the magnifying glass I don't think is possible (though I might be wrong?).

Ok if you don't mind disabling the text selection as well you can try this.

ObjC

[webView stringByEvaluatingJavaScriptFromString:@"document.onmousedown = function() {return false;}"];

JavaScript

document.onselectstart = function() {return false;} // ie
document.onmousedown = function() {return false;}
