the name of a feature in iBooks - ios

In iBooks there is a bottom bar filed with miniature images in which the user can scroll through and thus move between the pages I would like to know the name of the bar.

When you want to know about UI elements provided by Apple you need to refer to the iOS Human Interface Guidelines. In fact, this should be one of the first documents every iOS developer goes through in its entirety.
Going through this document will reveal that your question is about the Tab Bar. This is usually created with a UITabBarController.

does showing tab bar at top violate apple Human Interface Guidelines?

I am developing an app on which i want to show a tab bar at the top of the screen.When user tap on tab then it should redirect user to different screen.Normally i see tab bar at bottom.So What will happen if i show tab bar at top.
1.Does it violate apple human interface guidelines?
2. If i don't follow apple Human Interface Guidelines.Will apple reject my app on app store?
Please suggest me what to do?
Are you thinking tabs, as in browsers? If so, then no putting your tabs or a tab button in the top of the screen doesn't violate any guidelines. For example, the newly released Firefox for iOS has a tab button in the top right corner.
However, you should generally show how you have tried to find an answer, as the iOS Human Interface Guidelines provide clear guidelines about how you should design your app.

WatchKit Extension: Page-based hierarchy for glances

There is something confusing in Apple's Programming Guide documentation. While they are illustrating the glances they used a figure that shows a glance represented in a page based navigation.
But they ended it up saying this.
The question is, can i have multiple glances in a page based navigation?
The programming guide:
https://developer.apple.com/library/prerelease/ios/documentation/General/Conceptual/WatchKitProgrammingGuide/ImplementingaGlance.html#//apple_ref/doc/uid/TP40014969-CH5-SW1
In my opinion you little bit confused with this image.
Glance interface controller like home screen widget (or any else). It could be just in one screen and without any scrolling. Then user could choose best glances (from multiply apps) and then they will be in his watch home screen. This page base navigation at image about multiply glances from multiply apps.
And Apple mean that in you app (current and one) you could have only one glance interface controller that user could chose to be at home screen. Is it clear?
The image is confusing, but what's happening there is that the multiple "pages" are actually different apps. Each app can have its own glance, and then the user swipes through them just like a paged application, but each app can only contribute one page.

How can i add tabs in iOS on a particular screen?

I am building an app where I need to add a TabBarController on a particular screen, Lets assume maybe on second or third screen.
I have gone through several blogs but everyone says UITabBarController can be added as an initial view controller only.
But I want it for some few screens only. How can I accomplish it?
Need guidance!
The answer is "you shouldn't."
From the Human Interface Guidelines:
"In general, use a tab bar to organize information at the app level. A tab bar is well suited for use in the main app view because it’s a good way to flatten your information hierarchy and provide access to several peer information categories or modes at one time.
Don’t use a tab bar to give users controls that act on elements in the current screen or app mode. If you need to provide controls, including a control that displays a modal view, use a toolbar instead (for usage guidelines, see Toolbar). "

iOS app with Custom Tabbar

I am using a custom tabbar. Related to this I have a question regarding the iOS Human Interface Guidelines.
First I will state something about my app development process. In my custom tabbar, for example: if I select Settings, it will move to the settings view, but in that settings view there won't be Custom tabbar. Instead, there will be a back button. Like this, it'll be the same for the remaining tabs also.
Because of this, is there a problem while submitting the app to the App Store? Based on iOS Human Interface Guidelines, as far as I checked, there isn't any problem.
It's OK. No problem with that. I already added an app like this. Please check this one:
https://itunes.apple.com/us/app/photomatrix/id645791639?ls=1&mt=8
I added the gallery like you said (without any tab bar).

Can Tab Bar view be used only in the second screen application?

I am just starting out iOS development and have some doubts about Tab Bars Human Interface Guidelines provided by Apple.
On the iOS HIG document concerning Tab Bars, it reads:
"A tab bar appears at the bottom edge of the screen and should be
accessible from every location in the app."
The app I am developing and would like to see published in the App Store once finished, would have a ListView as it's first screen that would then go to another screen with a tabbed interface after an item being selected. It would also be possible to go back to the first screen (the one with the list) at any time within the tabbed interface (the 2nd screen).
So, my question is if it's ok to have a Tab Bar interface only in the second screen of an iOS application or would something like that might result in some restrictions by apple approving?
Thanks.
Short answer is YES.
Yes, you can have tab bar in second screen. Consider the app where you have first screen as language select screen and second screen with tab bar controller.
With statement below, what Apple means is once you are in tab-bar controller and tab-bar controller is in scope, tab-bar controller should be accessible. You can hide the tab-bar, but on tapping, it should come again at the bottom of screen.
"A tab bar appears at the bottom edge of the screen and should be accessible from every location in the app."
Main words -> Should be. Apple wants you to make your apps in the most intuitive and user friendly way possible. Many standard apps use this paradigm (ie App Store Application) so they know iOS users are accustomed as to how to navigate. However, Apple themselves even make exceptions to this rule (ie. Playing a song inside the Music App). But yeah, they'll let you do it no problem.
