How to show HTML text from API on the iPhone?
As David Liu said, UIWebview is the way to go. I would recommend a few building the HTML string separately and then passing it to the UIWebView. Also, I'd make the background transparent, using [webView setBackgroundColor:[UIColor clearColor]] so that you have an easier time making things look as they should.
Here's a code sample:
- (void) createWebViewWithHTML{ //create the string NSMutableString *html = [NSMutableString stringWithString: @"<html><head><title></title></head><body style=\"background:transparent;\">"]; //continue building the string [html appendString:@"body content here"]; [html appendString:@"</body></html>"]; //instantiate the web view UIWebView *webView = [[UIWebView alloc] initWithFrame:self.view.frame]; //make the background transparent [webView setBackgroundColor:[UIColor clearColor]]; //pass the string to the webview [webView loadHTMLString:[html description] baseURL:nil]; //add it to the subview [self.view addSubview:webView];}NOTE:
The benefit to using a 'NSMutableString' is that you can continue to build your string through an entire parsing operation and then pass it to the the 'UIWebView', whereas a 'NSString' cannot be changed once it is created.
self.textLbl.attributedText = [[NSAttributedString alloc] initWithData: [@"html-string" dataUsingEncoding:NSUnicodeStringEncoding] options:@{ NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType } documentAttributes:nil error:nil];
NSString *strForWebView = [NSString stringWithFormat:@"<html> \n" "<head> \n" "<style type=\"text/css\"> \n" "body {font-family: \"%@\"; font-size: %@; height: auto; }\n" "</style> \n" "</head> \n" "<body>%@</body> \n" "</html>", @"helvetica", [NSNumber numberWithInt:12], ParameterWhereYouStoreTextFromAPI]; [self.webview loadHTMLString:strForWebView baseURL:nil];I'm using this code to even set the font for the webview text and passing my ivar 'ParameterWhereYouStoreTextFromAPI' where I'm storing text obtained from api.
