uinavigationbar

问题 I have an UINavigationController with UINavigationBar hidden = YES. I want full screen bg for view that embedded in UINavigationController. But I get only that: http://cs616618.vk.me/v616618797/1bf0d/FEdIn0Nn4x8.jpg Is it possible to make it full screen under status bar? I achieved that with standalone view controller, but while using it in UINavigationController it becomes like on image. 回答1: Check that all your view controllers are correctly configured: The UINavigationController : The

问题 I'm trying to customize my navigationbar's UIBarbuttonItem so that I'm using this im my Appdelegate.m // didFinishLaunchingWithOptions: { UIImage *navBarImage = [UIImage imageNamed:@"nav-bar.png"]; [[UINavigationBar appearance] setBackgroundImage:navBarImage forBarMetrics:UIBarMetricsDefault]; [[UINavigationBar appearance] setTitleVerticalPositionAdjustment:5 forBarMetrics:UIBarMetricsDefault]; UIImage *barButtonSave = [[UIImage imageNamed:@"nav-bar-button.png"] resizableImageWithCapInsets

问题 When trying to add a navigation bar for searching on the left button and eventually a setting button on the right bar button, the bar isn't showing up in the simulator. Screenshot Should I be using a regular toolbar like the temporary one I have on the bottom? I'd prefer the search button for loading new addresses, and settings for the obvious, but then I want buttons that serve as navigations for moving from tab to tab. Should I simply implement a search bar above the map view and a settings

问题 Has anyone ever encountered an issue where a navigation bar with custom background is shifted to the top when the screen is transitioning between a hidden status bar and a shown status bar? The problem is this issue doesn't happen with a debug build, but it does happen with a release build. I'm really confused because I'm not using any conditionals for UI behaviors. Additionally, this will only happen if the app is entering a foreground mode in a "fullscreen" state. Then I switched from a

问题 What I have: I have a Xamarin.Forms app with a ToolBar ( ActionBar on Android, Navigation Bar on iOS). Within the ToolBar I have a ToolBarItem to delete something. What I want: For the ToolBarItem mentioned above I want to use the native platform icons (f.e. a trash can). My question: What is the proper way to achieve this? It seems that the only way to do this is to add and load separate png-files as described here. For Android this is not such a big deal I can officially download the icon

问题 I'm hoping to get some insight into an issue I've been struggling to wrap my head around for the past few hours. I have a custom UINavigationBar that is being configured in application:DidFinishLaunchingWithOptions by calling the following method: [[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"NavBar"] forBarMetrics:UIBarMetricsDefault]; When I run my application in XCode (both in the Simulator and on an actual device that is plugged in to the computer), this works

问题 I am trying to update my app for iOS 7. When my views appear on the screen, you can see that there is a gap between the navigation bar and the rest of the screen, and then the navigation bar "jumps" or "stretches" to fill the gap. This is causing my custom UIBarButtonItems to fall off the navigation bar. I tried to take a photo of the transition but it happens before the camera can take the picture. I have attached a picture of what happens to the button, however. Thanks for any advice.

问题 I have a storyboard that looks like the image shown. The single navigation controller manages my drill down navigation adds a Back button to all of the views 1,2,3 and 4 as I drill down. What I would like to do, is add an additional button on the "back" nav bar on the right for each of the 3 tab views (2,3 and 4) Can this be done in Swift? Can anyone help? I cannot add it using the storyboard as the button just seems to disappear on the storyboard and does not get displayed when I run the app

问题 Here is my code..I am unable to add a button in my navigation controller. - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; // Override point for customization after application launch. UIViewController *viewController1, *viewController2, *viewController3,*viewController4; viewController1 = [[ViewController alloc] initWithNibName:@"ViewController" bundle

问题 my first view named "back". I need to hidden the title of the navigationbar because I have my custom navigation bar. I try with this code but it didn't work! self.title = @"back"; self.navigationController.navigationItem.titleView.hidden = YES; 回答1: Just faced the same issue, and doing: self.title = @"YourTitle"; self.navigationItem.titleView = [[UIView alloc] init]; Did the trick. The next view will have the back button labeled with YourTitle but in the first one, the title won't be shown.
