当UIWebView无法从URL加载页面时，我试图在webView didFailLoadWithError委托方法中加载“错误页面”。我试图直接加载错误页面，它的工作完美。这里我的代码如下，
- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error {
// [webView stopLoading];
errorMessage = (errorMessage==nil?@"Sorry, there was an error loading the chapter":errorMessage);
refreshMessage = (refreshMessage==nil?@"Try reloading this chapter":refreshMessage);
NSURL *imagePath = [[NSBundle mainBundle] URLForResource:@"error_icon_2x" withExtension:@"png" subdirectory:@"/www/img/"];
NSURL *cssPath = [[NSBundle mainBundle] URLForResource:@"myexp" withExtension:@"css" subdirectory:@"/www/css/"];
NSString *errorHTML = [NSString stringWithFormat:@"<head><link rel=\"stylesheet\" type=\"text/css\" href=\"%@\"><script type='text/javascript'>function callReloadPDF() { window.location = 'ios:reloadPDF'; }</script></head><div style=\"position: relative; top: 35%%; transform: translateY(-50%%); \" class=\"errorPDFViewer\"><div style=\"\"><img src=\"%@\" width=\"30px\" height=\"30px\" class=\"newexpimgerroricon\"/></div><br /><div class=\"newexpsorrymessagelabel\">'%@'</div><div style=\"margin: 1% 30%;text-align: center; \"><button class=\"btnreloadPage\" id=\"btnreloadPage' + index + '\" onclick='callReloadPDF()'>'%@'</button></div></div>", cssPath, imagePath, errorMessage, refreshMessage];
NSLog(@"errorHTML: %@", errorHTML);
[webView loadHTMLString:errorHTML baseURL:nil];
}
任何帮助将不胜感激:)谢谢!!!
