Question

I am developing an pdf reader in which i have to load each page of the pdf book on finger swipe. For each swipe i am incrementing one page it is working fine if i am swiping slowly.where it is not at all working if the swipe is so fast it gets crashed.

hi folks i resolved the above issue with the NSobject class reference it has only two lines..

[NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(loadPagesAccordingToCurrentOrientation) object:nil];
[self performSelector:@selector(loadPagesAccordingToCurrentOrientation) withObject:nil afterDelay:0.5];

Answer 1
