I have text file with some random text and i want to display it in webview with increased font,my question is can i change the font size. here is my code i have implemented.
NSString * myString = [NSString stringWithContentsOfFile:_urlPath encoding:NSUTF8StringEncoding error:nil];
[self.webView loadHTMLString:htmlString baseURL:nil];
[self.webView setScalesPageToFit:YES];
self.webView.autoresizesSubviews = YES;
You have to know the exact structure of your html string and you would need to modify the html string to change the font and font size. Add/Modify html tags around required text in order to change font and/or font size.
Use NSMutableString instead of NSString and then modify your string according to your requirement.
Take a look at this question how to increase font size in UIWebView You could do it with a javascript command
Yes, you can do it by using html tags.
NSString *stringToLoad = [NSString stringWithFormat:@"<html><center><font size=+5>%@</font></center></html>", myString];
You need to convert your string to valid html string and then set font-family for html string:
NSString *myDescriptionHTML = [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>", @"HelveticaNeue", [NSNumber numberWithInt:kFieldFontSize], myString];
myString which u'll get from file. edited answer
