wait_fences: failed to receive reply: 10004003 in iphone

i am developing an application on ipad to read and annotate pdf's.My application is working fine in Portrait/landscape mode but when I rotates the device or simulator its giving me weired error wait_fences: failed to receive reply: 10004003 whenever i rotates either from landscape to portrait or from po开发者_Python百科rtrait to landscape.

some times my app is crashing and sometimes its not rotating properly because of this error. i googled about wait_fences but i didnt get anything.

can anyone please help me on this. Thanks in advance.

Here you are doing the following things in the method willAnimateRotationToInterfaceOrientation.

if([objGoToPagePopOverController isPopoverVisible])
{
    [objGoToPagePopOverController dismissPopoverAnimated:YES];
}

So, Here instead of calling this "dismissPopoverAnimated" method directly, make one custom method "Remove_Popover" and call that in timer like as follows:

[NSTimer scheduledTimerWithTimeInterval:0.001 target:self selector:@selector(Remove_Popover) userInfo:nil repeats:NO];

Call this method in NSTimer when you put the dismissPopoverAnimated code inside the willAnimateRotationToInterfaceOrientation method. And just make your own custom method as follows:

- (void)Remove_Popover
{
    if([objGoToPagePopOverController isPopoverVisible])
    {
        [objGoToPagePopOverController dismissPopoverAnimated:YES];
    }
}

Let me know if you can solve the issue.

withih willRotateToInterfaceOrientation i am calling my mythod where i am setting the landscape and portrait rects for all my UI elements

-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
    delegate.currentOrientation = toInterfaceOrientation;
    [self landscapePortraitOrientation];
}
