if "productDetilAPI" is a web request function, it will stop the UI, as mentioned in the above answer, so what you should do is

[self performSelectorInBackground:@selector(productDetailAPI)
                           withObject:nil];

Hope this help

Is the API call running on the main thread? You should make network calls on the background thread to not block the UI thread.
