I got expected expression error on DELAY(0.5) when running with xcode9.0.
It can run and no error in old xcode 8.
dispatch_after(DELAY(0.5),dispatch_get_main_queue(),^(void){
[_collectionView scrollToItemAtIndexPath:selectedIndexPath atScrollPosition:UICollectionViewScrollPositionRight animated:true];});
Thanks a lot for any ideas / suggestions / etc.
The first parameter to dispatch_after should be of type "dispatch_time_t" and DELAY(x) isn't anything meaningful in that context. Do you have a link to some documentation that suggests that it should work?
This is what you're looking for
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(5 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
[_collectionView scrollToItemAtIndexPath:selectedIndexPath atScrollPosition:UICollectionViewScrollPositionRight animated:true];}
});Hi QuinecyMorris,
Thanks for your reply and suggestion .
Actually the application is already on app store with that code.
Now I am checking that it can work or not in iOS 11. I got error in xcode 9.
Hi iTen,
Thanks for your reply.
