- (void) showWebView:(NSString *)htmlText{
[webView setHidden:FALSE];
[txtContent setHidden:TRUE];
NSString * htmlString = [NSString stringWithFormat:@"<html><head><style type='text/css'>body {background-color:transparent; } p { color:white; font-family:Helvetica; font-size:14px; } a { color:white; }</style></head><body><p>%@</p></body></html>", htmlText];
webView.delegate = self;
NSLog(@"htmlstring %@",htmlString);
[webView loadHTMLString:htmlString baseURL:nil];
}
Under iOS5 I found that sometimes a UIWebView would not load its content if
<meta charset="utf-8"></meta>
(or other equivalent charset specification) was not present in the HTML.
[webView setHidden:FALSE];
[txtContent setHidden:TRUE];
NSString * htmlString = [NSString stringWithFormat:@"<html><head><style type='text/css'>body {background-color:transparent; } p { color:white; font-family:Helvetica; font-size:14px; } a { color:white; }</style></head><body><p>%@</p></body></html>", htmlText];
