So NSXMLParser has problems parsing strings using the Windows-1252 encoder. Now I did find a solution on this page to convert it to NSUTF8StringEncoding. But now it bumps into characters it can't parse. So I figured out that it will work if I would escape special characters and then transfer it back after parsing it. For example: strin...

So what I did is pretty simple. I created a UIControl subclass, and overrided this, like this: - (void)sendActionsForControlEvents:(UICont...

I've tried breakpointing on - (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigation...
I don't want UIButton or anything like that. I want to subclass UIControl directly and make my own, very special control. But for some reason, none of any methods I override get ever called.
