Question

Apple AppStore中的我的应用程序有一个UIPopoverView，它只能部分呈现。它在屏幕上只显示一半，如屏幕快照中所示。它只是应用程序的少数客户而不是我的任何测试设备。

我不知道为什么会这样。

UIPopoverView由storybard-segue显示。在Parent-Tableview中只有这个代码：

- (void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    if ([segue.identifier isEqualToString:@"trips"]) {
        TripsTableViewController *tripsTableViewController = segue.destinationViewController;
        tripsTableViewController.mapView = [self mapView];
    }
}

它是UINavigationViewContoller的一部分，其中没有代码。我已经尝试将UIPopoverView的启动移动到工具栏中的额外调试按钮，该按钮使用故事板中的非特殊segue来启动UIPopoverView。结果相同。如上所述，它只出现在应用程序用户（Pilots Atlas）报告的百分之几的设备上。它并没有出现在我的任何测试设备上（大约10种不同的测试设备）。

毫无疑问，alpha在任何地方都不会改变。查看左右NavigationBarButtons，它们已经显示为正常。

UIPopoverView仅部分呈现
