uinavigationbar

问题 I have view which contains a scrollView. When the view shows up the image appears in full screen (320x480) hiding the status and navigation bar. When I tap the screens - status and navigation bar appears on the screen. But this thing shifts the UIScrollView below the the navigation bar. I want the status and nav bar to show over my scroll view. Like it happens in the photos app. On tapping the image the status and nav bar shows over the scrollView. Below is how I am positioning the view /

问题 Check out the fiddle. I have a basic Bootstrap 3 responsive nav like so: <div id="navbar" class="navbar navbar-fixed-top navbar-inverse"> <div class="container"> <a id="navbar-toggle" class="navbar-toggle" data-toggle="collapse" data-target=".nav-collapse"> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </a> <a class="navbar-brand" href="#">Title Title Title</a> <div id="nav-collapse" class="nav-collapse collapse"> <ul class="nav navbar-nav"> <li>

问题 I'm working on an app that uses a custom image for UINavigationBar and UIToolbar, which is fine, but they also need a drop shadow below the nav bar and above the toolbar, which would always rest above all other view controllers. I cannot simply make background images which include the shadows as this would not work well with my tableviews. I also need the shadows animate away when I set nav bar and tool bar to hidden (animated). I've looked through Stack Overflow and other sources on the net,

问题 I am trying to hide the statusbar but maintain the "bigger" navigationbar height. Right now when I hide the statusbar by setting - (BOOL)prefersStatusBarHidden to YES and then calling [self setNeedsStatusBarAppearanceUpdate]; . The problem with this is that the navigationbar will slide up and won't leave space for the notification I'm trying to show. Simply adding a view over the statusbar is not an option, our statusbar/navigation has the fancy blur effect. Does anyone have a clue how to

问题 I want to change the color of my right bar button item from black to white. It is a button as a search icon. I have not coded the search implementation yet as I want to get the main interface completed first. I thought that I'd written the correct codes so it should appear as white, but it seems to still appear as black in both the storyboard and simulator. In the storyboard, I have also set it to white. Here is my code, which is located in the AppDelegate.swift file: func application

问题 I'm just wondering what UINavigationBar's default color is (on the iPhone). I can't find it anywhere, and calling CGColorGetComponents() on navigationBar.tintColor.CGColorRef has no effect. For example, if I programmatically set the color to, let's say, red, how do I get it back to normal? Any help appreciated. 回答1: To get the default look, you'd set the tintColor to nil . It's not possible to set it to an instance of UIColor and have it look completely the same as in the default style,

问题 I have 6 view controllers on a UITabBarController. Each of them has a UINavigationBar at the top of them (Not linked to a UINavigationController), for showing the title of that view controller, and some buttons for controlling it. This was fine while I had 5 controllers, as no 'More' button would appear, but when I add a 6th, the more button appears. The tabs under that end up having two UINavigationBars! One is the one I added, with my title, the other is created by the TabBar and has a

问题 I have a UITableView with a navigation bar on the top. I changed the style of the navigation bar to Black Opaque to go with my theme. I added an edit button as well using the below line of code self.navigationItem.leftBarButtonItem = self.editButtonItem; All is fine so far, the edit button also appears in the balck opaque style. however the done button appears in the default blue theme. Am i missing some simple thing? How should i change it? Help would be appreciated 回答1: The done button is

问题 What I want to to: I want to drag down the whole view of a viewController to dismiss to the parent viewController using a pan gesture recognizer. The Problem: When I drag the view down, the navigationBar decreases its height and does not look good. When the view returns to its original position, the navigationBar returns to the default size. I want the navigationBar to stay at its size. I also tried to use the new large titles and some other properties of the navigationController/-bar, but

问题 I've got a button on a view. When I click on it, it should load another view, one with a novigation controller. So far I've got this, the button calls this method: -(IBAction)loadOptionsView:(id)sender { if (self.optionsRootController == nil) { //optionsRootController is declared as: UINavigationController *optionsRootController; optionsRootController = [[UINavigationController alloc] init]; //Options is a UIViewController Options *myOptions = [[Options alloc] initWithNibName:@"OptionsMenu"
