The iPhone iOS podcast app has a trailing bar button item that behaves differently than most UIBarButtons. You can see it on the Listen Now page. It's the button on the top right that takes you to the account page. It is lower than normal, and it's inline with the title of the NavigationBar, and it is bigger than normal. Most importantly it scrolls up with the navigation title and disappears under the compact Navigation Bar. (The App Store app has the same behavior on the "Search", "Games" and "Apps" tabs.
Does anybody know how to get this behavior in either SwiftUI or UIKit? I haven't seen anyone else reproduce this and I wonder if this is something that only Apple has access to.

I have a view controller that is composed of a web view and a toolbar with some basic controls. The toolbar is pinned to the bottom of the screen using auto layout. It has four constraints, to pin it to the left side of the screen, the right side of the screen, the bottom of the screen and another that pins the bottom of the web view to the top of the toolbar.
I am having too issues with this. The first is that the web view when loading a URL has a black bar running across the bottom of the screen for a second or two while the page loads, see attached screen shot. This occurs on both iOS7 & iOS8.
[EDIT]
This bug and the one below are related I think. I just discovered that the horizontal indicator when scrolling displays not at the bottom of the screen but higher up, where it would appear if the tabbar where present.
[/EDIT]
The second issue I am having with iOS7. The screen that calls this screen is the typical navigation bar inside a tab bar setup. The user presses a button to go to a particular page, the browser gets created and pushed onto the navigation bar stack. It hides the tab bar when created. In iOS8 this works perfectly, the toolbar is pinned to the bottom of the screen. In iOS7 the tab bar is removed but the toolbar is placed as if the tab bar was still present?! Any ideas how to fix these two issues? Many thanks.
FYI - Xcode 6.1.1
The "black bar" is most likely your app window background. At the time of loading the web view is still under the navigation bar. Perhaps the constraints are being overridden. Check your storyboard settings:
If this is it, it might solve the second issue as well.
Speculation
The reason iOS 8 works is because from Apple talks I gleaned they realise many dev had issues with their views being under the nav bars by default. Introduced with iOS 7. They likely changed this in iOS 8 but found no written evidence. If someone can confirm or deny this, I'll update the answer.
I'm currently developing an iphone app where I have one screen that includes a web view. I was wondering where to place the toolbar (back, forward, and refresh buttons) knowing that I have to keep the navigation bar for consistency reasons and there is the tab bar which is always showing in my app. I don't want to place the toolbar just under the navigation bar in order not to loose space for the content of the web page.
Can I include my toolbar controls (back, forward, and refresh buttons) in the navigation bar or by that I will by violating the iOS guidelines ? What is the best user experience here ?
Thanks in advance.
Best Regards,
Place your toolbar at the bottom of the screen. It wouldn't be a good user experience to have browser controls on the nav bar because it's easy to confuse nav bar "back" with browser "back", and generally there isn't enough rooom.
You'd be in good company if you did this - it's what the Facebook iPhone app does (and many others).
Note: the iPad Facebook app does put some browser controls on the RHS of the nav bar, because there's enough room.
You should use a toolbar, but set controller.hidesBottomBarWhenPushed = YES on the web view controller, so that your tab bar is not visible while in the web view.
You should probably also use https://github.com/samvermette/SVWebViewController and save yourself a lot of time ;)
I'm completely new to iphone apps. I'm creating an iphone app that is designed in HTML and jquery with phonegap. I want to include a back button on the top like the default one in the iphone. I searched on net but all i found, required view controllers.I don't have multiple views so how can i include a back button on my app. Step by step explanation would be very helpful.
Thanks in advance..:)
Why would you include a "back" button if you don't have multiple views? What exactly will you navigate "back" to?
"The net" is correct, you need a UINavigationController to house a "back" button which would pop a view to the previous view.
Other than a UINavigationController, you could use a UIToolbar and set a button to the left hand corner and give it the title of "Back" to simulate the native appearance — but this would be misleading and pointless.
I don't use PhoneGap, but I am sure there is a way to simulate a NavigationController and manually place a button there. I'm also sure it won't be shaped like a back button either (with the pointy end).
javascript:history.go(-1)
UINavigationController is a native control which is in iOS frameworks. As you are using HTML, jQueryMobile and phonegap you should not be looking at those controls. You should totally work in your HTML pages and CSS for that purpose.
The below page contains that back button in jquery mobile. You should be implementing this in your html page.

I have a UIWebView controller that loads a web page and I would like to add some kind of a bar at the top of the page with refresh and close buttons.
The bar should hide when the page loaded and should show again if the user taps the top part of the page.
Does anyone know how to approach it? Is there any simple way to do that?
UPDATE:
I think I wasn't clear enough with the question, so here are some clarifications:
1. The applications is a standard application that one of the flows opens UIWebView that loads a web page
2. What I'm looking for is a bar that will slide down on top of the web page (loaded in UIWebView) and should help the user overcome a scenario where the web page is not loaded for some reason
3. The bar should hold the back (just close the UIWebView) and refresh (reload UIWebView) operations.
Hope it helped.
Thanks,

I'm working on something like this right now and so far, here's what I've come up with. Some of this may be obvious, but important:
Your address bar should be the left navigationItem.
The search bar is the rign navigationItem.
You should animate a cancel button in/out when beginning/ending editing in the URL box.
Safari Mobile uses the Prompt property of the navigationBar to display webpage titles.
To animate the widths of the search/URL bars, use UIView animation when the bar is selected.
It's pretty simple to add a UIToolbar above the webview with UIBarButtonItems that call the webview's refresh, back, and forward methods. You can also add the webviewdelegate methods to your view controller to detect when the page has finished loading and hide/show the toolbar that way.
If you want the refresh and navigation controls to be displayed as part of the html content of the webview itself, that's a littler tricker, but not impossible. You can use the webview's shouldLoadRequest delegate method to detect that those buttons have been tapped, and then take the appropriate action within your viewcontroller. Hiding and showing the nav bar would have to be handled in javascript.
Unless I'm missing a library/project doing this, I don't think there is a simple way to do this.
I have already coded something similar to Safari mobile address bar, and from memory, it involved using private apis and/or playing with the "not so private but use at your own risks" UIWebView subviews hierarchy...
I'm wondering if it is possible to start my app with all my tabs in the "up" state and show a "landing" view to the user. Kind of like a welcome/quick start. When they select one of the tabs, it switches views as normal.
Will you point me in the right direction?
Kind of like this:
If you're using a UITabBar/UITabBarController, I think you must have the selectedIndex set to some legal value. I don't think this is possible, nor can I find an app on my iPhone or iPod that mimics the behaviour you're looking for.
(The App Store app is as close as it gets, where it looks like it has an empty tab bar before it loads data from the Internet, but it could very well be that they are just re-using the Default.png and superimposing an activity indicator during loading.)
Note that if you tried to submit your app to Apple, they could easily reject it for using non-standard UI.
The way I would probably do this is to create a new ViewController that's just for this screen, but make sure it's last in the viewControllers array managed by the UITabBarController. That way, when you show the tab bar on the screen, you get the 4 tabs and the more button, but the currently selected view controller is not in the bar, meaning that all of the other tabs are unselected.
Once the user has satisfied the condition for showing the screen, you can discretely remove the view controller from the tab bar, and the user will never be the wiser.
