UIWebViewDelegateを利用する。

Interface BuilderでUIWebViewのdelegateを設定する。


以下のコードを追加

// リンクをクリック時、Safariを起動する為の処理
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
 if (navigationType == UIWebViewNavigationTypeLinkClicked) {
  NSLog(@"URL = %@", [[request URL] absoluteString]);
  [[UIApplication sharedApplication] openURL:[request URL]];
  return NO;
 }
 
 return YES;
}
