HTML Content fit in UIWebview without zooming out
Here's what you do:
In your UI controller that owns the web view, make it a UIWebViewDelegate.Then where you set the URL to load, set the delegate as the controller:
NSString *urlAddress = @"http://dl.dropbox.com/u/50941418/2-build.html";NSURL *url = [NSURL URLWithString:urlAddress];NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];[webView loadRequest:requestObj]; webView.delegate = self;And finally implement the webViewDidFinishLoad: to correctly set the zoom level:
This option will applicable from iOS 5.0 and >
- (void)webViewDidFinishLoad:(UIWebView *)theWebView{ CGSize contentSize = theWebView.scrollView.contentSize; CGSize viewSize = theWebView.bounds.size; float rw = viewSize.width / contentSize.width; theWebView.scrollView.minimumZoomScale = rw; theWebView.scrollView.maximumZoomScale = rw; theWebView.scrollView.zoomScale = rw; }I hope this helps...
Option B, you can try to alter the HTML (this example does the job but is less than perfect from an HTML parsing standpoint. I just wanted to illustrate my point. It does work for your example, and probably most cases. The inset of 40 can probably be detected programmatically, I didn't try to research that.
NSString *urlAddress = @"http://dl.dropbox.com/u/50941418/2-build.html";NSURL *url = [NSURL URLWithString:urlAddress];NSString *html = [NSString stringWithContentsOfURL:url encoding:[NSString defaultCStringEncoding] error:nil];NSRange range = [html rangeOfString:@"<body"];if(range.location != NSNotFound) { // Adjust style for mobile float inset = 40; NSString *style = [NSString stringWithFormat:@"<style>div {max-width: %fpx;}</style>", self.view.bounds.size.width - inset]; html = [NSString stringWithFormat:@"%@%@%@", [html substringToIndex:range.location], style, [html substringFromIndex:range.location]];}[webView loadHTMLString:html baseURL:url];
Typically, you should use the viewport meta tag. But its use is very erratic, mostly if you want a cross platform web page.
It also depends of what content and css you have.
For my iPhone homepage, which must auto-resize from portrait to lanscape, I use this :
<meta name="viewport" content="width=device-width; minimum-scale=1.0; maximum-scale=1.0; user-scalable=no">If you need special resize, you can also use the event :
<body onorientationchange="updateOrientation();">with the corresponding funciton in your javascript :
function updateOrientation() { if(Math.abs(window.orientation)==90) // landscape else // portrait }EDIT :
Seeing you page source, it seems you made it with a web editor, don't you ?
Ok, I understand. Your main div has a width of 600px. The iphone screen resolution is 320x480. 600 > 320 so it exceeds the screen bounds.
Now, let's make some simple operations:
320 / 600 = 0.53480 / 600 = 0.8So you want to zoom out 0.5 times minimum and 0.8 times maximum. Lets change the viewport :
<meta name="viewport" content="width=device-width; minimum-scale=0.5; maximum-scale=0.8; user-scalable=no">
