iPhone XCODE Programming make a UIWebView Scrollable - iphone

Question

here is the problem! I have a UIWebView in my programs that loads a php page.
The problem is that if the page has a lot of lines i cannot see them.
I can "scroll" the UIWebView but when I leave the finger from the screen the page comes back to the original state.
I don't want to scale pages to fit the view cause if I do that the letters become too small.
I would like to find a way to scroll pages how it is possible in Safari.
Hope i have explained the problem.
Thank you in advance
Antonio

Answer 1

If you have control of the web page, it is easier to control the UIWebView with http than programmatically.
<meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0; minimum-scale=1.0; user-scalable=0;" />
<meta name="apple-mobile-web-app-capable" content="yes" />

Answer 2

I would recommend applying the following:
Set scalesPageToFit=YES before the UIWebView gets loaded. I know you don't particularly want to scale the whole thing - but once you can scroll and zoom then having a macro view can be a good starting point.
Set the bounce behavior, within
- (void)webViewDidFinishLoad:(UIWebView *)theWebView {
//turn multi touch on for theWebView!!!
theWebView.multipleTouchEnabled = YES;
//control bounces and bounesZoom for the boundary
[[theWebView.subviews objectAtIndex:0] setBounces:YES];
[[theWebView.subviews objectAtIndex:0] setBouncesZoom:NO];
....
These two things did the job for me.

Answer 3

You should have a look at the scalesPageToFit-Property of the UIWebView.
http://developer.apple.com/iphone/library/documentation/UIKit/Reference/UIWebView_Class/Reference/Reference.html#//apple_ref/occ/instp/UIWebView/scalesPageToFit

Answer 4

you can always use
UIWebView *wv = [controller webbrowser];
[wv loadHTMLString:pageUrlToLoad baseURL:nil];
wv.scalesPageToFit = YES;
It does the trick for me.
it will try to fit the entire page in the window.
ADD ON:
write UIWebView in XCode window and pressing the ALT key, double click on it.
it will show the Fast Help window, there you can find projects using that View
click on UI Catalog and when it opens, click the button Open with XCode
select the folder you want to have all the project files and go
select the iPhone Simulator 3.1.3 as the target device and Run the app.
You will get a lot of User Interfaces and all the code they use is right there so you can copy/paste and change to your own way.
give it a shoot!
