• Client-side Twitter API method using XMLHttpRequest?

  - by user359239

  Does (or did) Twitter ever have a method in their API that allowed client-side HTTP requests without producing any cross-domain issues? I have a site that used the following url: http://search.twitter.com/search.json?q=from%3adaleyjem&rpp=3&page=1&callback=? It once worked, but now it doesn't.

• How to find out if a method exists in Obj-C when given an NSString

  - by Justin

  I have a method as an NSString *. If it exists, I want to call it, and if not, do nothing. SEL eventSelector = NSSelectorFromString(eventSelectorStr); if ([delegate respondsToSelector:eventSelector]) { [delegate performSelector:eventSelector]; [delegate adapterDidFinishAdRequest:self]; } else { // Does not implement selector } This code does not work, since NSSelectorFromString will register the string as a selector, so respondsToSelector:eventSelector will cause a crash because the selector is actually invalid.
