ios - UIWebView content how to resize/scale it? -


i came point able lock horizontal scroll wanted when rotate landscape portrait content still large. need resize/scale down myself don't know how far use :

- (void)viewdidload  {     [super viewdidload];     nsstring *fullurl = @"http://igo.nl";     nsurl *url = [nsurl urlwithstring:fullurl];     nsurlrequest *requestobj = [nsurlrequest requestwithurl:url];     [_webview loadrequest:requestobj];     _webview.scrollview.bounces = false;     _webview.scalespagetofit = yes;     _webview.contentmode = uiviewcontentmodescaleaspectfit; }       - (void)didrotatefrominterfaceorientation:(uiinterfaceorientation)frominterfaceorientation     {          if(frominterfaceorientation == uiinterfaceorientationportrait)         {             //_webview.scrollview.contentsize = cgsizemake(320, _webview.scrollview.contentsize.height);         }         else         {             //[_webview reload];             _webview.bounds = cgrectmake(0, 0, 320,_webview.bounds.size.height);             _webview.frame = cgrectmake(0, 0, 320, _webview.frame.size.height);             _webview.scrollview.contentsize = cgsizemake(320, _webview.scrollview.contentsize.height);          }     }

edit: seem need content zoomed out

use delegate methods of uiwebviewdelegate

@interface your_class : parent_class <uiwebviewdelegate>

in viewdidload

... [_webview setdelegate:self]; ...

call delegate method 

- (void)webviewdidfinishload:(uiwebview *)webview {      [webview.scrollview setcontentsize: cgsizemake(webview.frame.size.width, webview.scrollview.contentsize.height)];  }  - (void)willrotatetointerfaceorientation:(uiinterfaceorientation)tointerfaceorientation duration:(nstimeinterval)duration {     [_webview reload];    //or use meta tag      [_webview.scrollview setcontentsize: cgsizemake([_webview.scrollview.contentsize.width, _webview.scrollview.contentsize.height)]; }

you have add meta tag html file

<meta name="viewport" content="width=device-width" />

or reload webview

[_webview reload];
