performSelector:withObject:afterDelay: not working from scrollViewDidZoom

Question

I feel like I should know this but I\'ve been stumped for hours now and I\'ve run out of ideas.

Answer 1

I think that timer events are ignored during tracking (when a finger is down in order to scroll or zoom). You might have to perform the selector in a different mode (see [NSObject performSelector:withObject:afterDelay:inModes:]). Specifically, try using @[NSRunLoopCommonModes] for the mode.

Answer 2

Just to add onto what Brian said - here's my implementation of his answer:

[self performSelector:@selector(callMethod) withObject:0 afterDelay:1.0 inModes:@[NSRunLoopCommonModes]];

Note - inModes: takes an array of modes.
