I'm very new to Objective-C and Cocoa but I've made a simple app which uses ImageKit to present a slideshow using the IKSlideShow class. However I've got a bit stuck with something I thought would be simple. I want to increase the time photos are displayed on screen when the slideshow is playing, but I can't see how to do it effectively.

The IKSlideshowDatasource protocol lets you do stuff when "slideshowDidChangeCurrentIndex" which seems to be the best place to do this - however I've tried putting various delays in here such as:

while ( functionShouldPause )
    {
        [[NSRunLoop currentRunLoop] runUntilDate:[NSDate dateWithTimeIntervalSinceNow:20]];
        functionShouldPause=NO;
    }

However they prevent the user for manually moving on the slides, or leaving the slideshow.

Very grateful for any suggestions. Thanks!
