Change font size for web view in Iphone SDK

问题

I have implementing feed parsing & get the content as a string. Now, I am making html file through it programetically. Load that HTML in the Web view. My web View is the subview in Table View cell.

But Now i want to change the font size of web view content, so the user can see some detail .

My code for HTML generation is:

NSString * postHTML=[[_parseResults objectAtIndex:indexPath.row]valueForKey:@"summary"];

 NSString *close =[NSString stringWithFormat:@"</body></html>"];

    NSString *HTMLString = [NSString stringWithFormat:@"%@%@", postHTML,close];

    [Web_view loadHTMLString:HTMLString baseURL:nil];

[cell.contentView addSubview:Web_view];

return cell;

How can i change font size of web view content??

回答1:

[myWeb loadHTMLString:[NSString stringWithFormat:@"<div style='text-align:justify; font-size:45px;font-family:HelveticaNeue-CondensedBold;color:#0000;'>%@%@",postHTML,close] baseURL:nil];

you can set font size in font-size:size in code.

try this..let me know it is working or not!!!

In UIWebView, you can use all HTML Tags while passing the data.

[WebView loadHTMLString:[NSString stringWithFormat:@"<div style='text-align:justify; font-size:44px;font-family:HelveticaNeue-CondensedBold;color:#ffff;'>%@",Data] baseURL:nil];

Use above code where "Data" will be your content.

set in your html

NSString *string = [NSString stringWithFormat:
                        @"<html> \n" "<head> \n"
                        "<style type=\"text/css\"> \n"
                        "body {font-family: \"%@\"; font-size: %@;}\n"
                        "</style> \n"
                        "</head> \n"
                        "<body>%@</body> \n"
                        "</html>",@"Helvetica",[NSNumber numberWithInt:17],
                        @"<p><i>My data</p>"];
