Question

Image cannot be zoomed in out when loaded into UIWebView

Answer 1

+1 A:

add this to your webview HTML, basically use an image tag and place the meta tag in the HTML String

NSString * header = @"<meta name='viewport' content='width=320; initial-scale=1.0; maximum-scale=2.0; user-scalable=1;'/>"
NSString * html = [NSString stringWithFormat:@"<html>%@<img src='%@'/></html>",header,imageData]
[webView loadHTMLString:html baseURL:nil];

Aaron thanks for the advice but there is no HTML. In this case loadData is loading the raw image data into a UIWebView.
