Search Bar in a Navigation Item collapses and gets stuck under status bar upon navigation pop, on iOS 11

由 我与影子孤独终老i 提交于 2019-12-07 04:15:39
问题 I am using the new iOS 11 searchContoller property of a UINavigationItem . I am running iOS 11.0 GM build. When I perform a push segue whilst the search controller is active, it works fine. When I subsequently pop back, the search bar is collapsed and squashed up in the status bar. I cannot then cancel the search, or edit the search text. See the following sequence of images: The final image is showing the appearing of the table during the pop segue to return from a presented view controller

UIBarStyleBlack vs tintColor black

由 主宰稳场 提交于 2019-12-07 03:14:49
问题 What is the difference between setting the tintColor property of UINavigationBar to [UIColor blackColor] and setting barStyle to UIBarStyleBlack on opaque navigation bar? 回答1: There are a few subtle differences. For example, on iPad, you get a matte style with the tint color, but a glossy one with the barStyle . Also, the color of bordered UIBarButtonItem s is slightly different; with the black barStyle , they are gray, which makes it easier to distinguish the darker highlighted state, while

Navigation Bar Changes Height

由 送分小仙女□ 提交于 2019-12-06 19:50:28
When I push my UIViewController to the screen from my previous controller it animates the change. But when it finishes loading it resizes my navigation bar and the jumpy transition makes it look bad. How can I fix this? All I'm doing is hiding the navigation bar in Controller A in viewWillAppear and showing it in Controller B in viewDidLoad . Ok solved it. In viewDidLoad of Controller B (the view controller I'm pushing) add the following: UINavigationBar *navigationBar = self.navigationController.navigationBar; [navigationBar setBackgroundImage:[UIImage new] forBarPosition:UIBarPositionAny

TabBarController in NavigationController does not show TabBar in viewControllers

由 狂风中的少年 提交于 2019-12-06 16:38:17
I have a UITabBarController to whose controllers I would like to attach navigation. So I inserted the NavigationController as the entry controller, and the tabBarController as its root. All seems working fine, but for the tabBar. Basically it does not show, albeit the StoryBoard I attach seems to say differently. I also attach the Account Screen not showing any navigation bar nor, of course, any back button. Thanks, Fabrizio Just a quick answer. I think you should put UINavigationController inside the TabBarController instead of the other way round. It will solve most of your problems. Steps:

问题 Can anyone tell me how to hide the navigation bar in my storyboard. My code below is working fine when running in the simulator but it still appears in my storyboard which is really annoying me as it's messing around with the placement of my images. Can anyone help? - (void) viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; [self.navigationController setNavigationBarHidden:YES animated:animated]; } - (void) viewWillDisappear:(BOOL)animated { [super viewWillDisappear:animated];
