问题描述
在iOS 8(XCode 6.0.1,iPhone 6)中运行我的应用程序后,后退按钮不会隐藏。
After I run my application in iOS 8 (XCode 6.0.1, iPhone 6), the back button does not hide.
我的代码:
- (void)removeCategoriesButton
{
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {
[_navigationController.topViewController.navigationItem setHidesBackButton:YES];
[_navigationController.topViewController.navigationItem setLeftBarButtonItem:nil];
} else {
UIViewController *controller = _app.window.rootViewController;
if ([controller isKindOfClass:[UINavigationController class]]) {
UINavigationController *nav = (UINavigationController *)controller;
[nav.topViewController.navigationItem setHidesBackButton:YES];
[nav.topViewController.navigationItem setLeftBarButtonItem:nil];
}
}
}
但后退按钮没有hide(见截图):

我在其他模拟器中运行应用程序,我看到这个错误只在iOS 8上。
I run application in another simulators, and i see this "bug" only on iOS 8.
