UIAlertController *alert = [UIAlertController alertControllerWithTitle:NulL message:NulL preferredStyle:UIAlertControllerStyleActionSheet];[alert addAction:[UIAlertAction actionWithTitle:copyKey style:UIAlertActionStyleDefault handler:alerAction]];[alert addAction:[UIAlertAction actionWithTitle:shareKey style:UIAlertActionStyleDefault handler:alerAction]];[alert addAction:[UIAlertAction actionWithTitle:cancelKey style:UIAlertActionStyleCancel handler:alerAction]];//THIS liNE CRASHED IT[self presentVIEwController:alert animated:1 completion:NulL];
我刚刚没有在iPad上进行过充分的测试,当我尝试使用插入的调试器时崩溃并给了我一个冗长的有用信息,这里有一段摘录“你必须通过警报控制器的popoverPresentationController为这个popover提供位置信息” .所以这就是我现在呈现它的方式并且它有效.
[alert setModalPresentationStyle:UIModalPresentationPopover];UIPopoverPresentationController *popPresenter = [alert popoverPresentationController];popPresenter.sourceVIEw = self.vIEw;popPresenter.sourceRect = alertSourceRect;[self presentVIEwController:alert animated:YES completion:nil];总结
