I want to know if it is possible to find the refresh rate for the iPhone screen, programmatically. I have searched, but have found no private API available.
Is there any way to find this out?
Thanks in advance.
I believe the iPhone screen refresh rate is fixed to 60Hz, but you can test this yourself using the CADisplayLink API which will call a selector you choose whenever the screen is updated
Use something like:
CADisplayLink *displayLink = [CADisplayLink displayLinkWithTarget:self selector:@selector(update)]; [displayLink addToRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
