Tabs-like behaviour in iPhone app - iphone

I have an iPhone app which I need tabs-like behaviour in. I want to show and hide all the views for each tab accordingly. For two tabs, I place all the views on top of the others and make them hide and show accordingly. But when I have to implement 3rd tab, there are a lot of views which I can't place on each other in Interface Builder.
Can anybody tell me how to make an UI for this scenario?
Edit: could you take a look at this and see if it makes any sense?

Ah, I see! Why not just do it yourself with some creatively placed UIButtons? So long as they are in fixed positions, make a sort of radio-group like paring of two buttons approximately 50 px apart from each other and then just set their background colors accordingly. As for the views, they can easily be called to the front with UIView's -bringSubviewToFront: method.

Xcode 11 Safe Area Does Not Go FullScreen

Since I am using Xcode 11 I am having problems with the Safe Area. My App is an ArKit- App that uses an ARSCNView. after upgrading to Xcode 11 the safe Are doesn't allow me to display it full screen anymore. Actually all the views in all ViewControllers can't be displayed in full screen. I really don't know where to start. Did anyone experience this kind of behavior?
Thanks!
Edit:
I unchecked all the necessary boxes I hope. The behavior I still get is this:
Storyboard Main
Inspector
Live View
There seems to be a view underneath. But I never added one and the inspector doesn't show. This changed with xcode11.
I just found out what happened to my ViewControllers. I am checking for internet connection with a LaunchViewController. The segue from this controller to the next one did not specify "full screen". I still don't know why I have to explicitly tell the segue to do so in Xcode 11. But in the end that solved my problem.
Thank you
The Safe Area is used as a reference for constraints for views and objects that you want the user to be able to interact with. It is used as a guide during the layout of objects on the screen. If you want to take advantage of the entire screen, constrain your views to the superview (basically the main view of the view controller). This is handy for displaying things like backgrounds on the entire view. Take a look at Apple's human interface guidelines for more info:

best approach for modal text popup, after user clicks on "assistance" icon?

In terms of providing a nice text popup for users in an iPhone application, after they click on a help icon, what approach/style do people recommend?
In my view (re User Experience) I would have thought something that say:
has a thin border with rounded edges around it
takes up most of the screen
has a vertical scroll bar if there is more text than can fit on one screen
has a way for the user to dismiss

The thing about designing iPhone UI elements, including popups, is that you're very strongly recommended to do it "Apple's way" - follow their Human Interface Guidelines and use standard UI controls. The two ways I can think to do this offhand:
Use a UIAlertView for a single chunk of text - it includes buttons for dismissal, properly shaded and colored for consistency with the rest of the OS and other apps. This is a quick, one- or two-line way of putting text on the screen and taking it off again. The downside: there's no scrolling capability, and the box scales with the text you put in it (i.e. you can't fix a size for the view).
Use a new view (in a UIViewController) presented modally. This option gives you more flexibility and the capability to scroll, but at the cost of greater setup.
If you decide to go the second route, follow your existing instincts for how to lay it out - you'll take over the entire screen on an iPhone, so you have some wiggle room. Your rounded-edges guess and vertical scrolling are right on (consider a UIScrollView for implementation).

How to Display Two Scrolling TextViews At Once

I'd like to display two windows on screen with scrolling text in them e.g. top window will have one bible translation while the bottom view would have another.
Ideally, I'd like them to stay in sync so they're both showing the same point in their respective translations (i.e. switch to John Ch1 in top view, bottom view follows and does same). But for now I'm just curious how to get these into two seperate viewable windows.
Any ideas?
In all honesty, I dont think you have the screen space to do this for the iPhone in such a way that is visually comfortable for the user.
That aside, the best method would depend on how the rest of your app is built. You can create a view that contains two UITextViews in it, each taking up roughly half the screen. You should be able to scroll one as a response to the other scrolling, though I haven't done this, so I cannot tell you how to do it exactly.
Another option that you have is to use a main UITextView, and then a second UIModalView that is overlaid above it. It all depends on the app structure.
Just to note, unless you have specific markers for points of translation, it would be very hard to have them sync up in that way. You could try to match line numbers, or something like that, but due to languages being so different, one might take 3 lines, and a translation might take 4 to say the same thing.
This is a fairly basic question, so you should perhaps revisit the iOS Application Programming Guide, but in a nutshell, you'd have two UITextView elements inside a view in your application, and you can synchronize between them using the built in setter method
- (void)setContentOffset:(CGPoint)contentOffset animated:(BOOL)animated
You have two needs here:
(1) You need to create a data model that can hold the translations and link each chapter and verse in each translation to the chapter and verse in all the other translations. For that, I would suggest learning Core Data. Be prepared to spend some time learning it.
(2) You need to display the translations. For this I would suggest you use two UITextViews in the same containing view. However, as Karoly S noted, there really isn't room on an iphone screen for two text views. I would recommend using two views connect by a flip transition which will allow you to have one translation on a full screen and then flip over to the other translation. The user could flip rapidly back and forth to compare.

iPhone - Proper UI controls for calculations

I am pretty new to iPhone development and currently working on an application which includes a view that performs a simple numerical calculation. In particular, the user enters 3 or 4 values into text fields and the view displays the result. Something along the lines of http://www.moneychimp.com/calculator/compound_interest_calculator.htm
What is the nicest way to achieve this? I am currently using simple UITextFields and a UILabel for the result but it doesn't look nice or "native-like". What UI object would be best to use?
Thank you!
It's entirely up to you. You're using the right classes for actual input- it comes down to how you choose to style those classes. I'd suggest looking at the documentation for UIView and CALayer (youView.layer, and include QuartzCore framework in your project).
A good start might be to choose a color scheme, a background for your app, and the look and feel you're shooting for- this will inform your styling. Try looking for apps that you think are elegant and attractive, and boil down what they do and what you like about them.
I'd say;
use a grouped table style (with the white tables with round corners on a blueish striped background)
embed settings values directly in the cell (aligned to the right) as much as possible
you can show a relevant keyboard (text, numbers) or picker view to let the user pick values, directly when they tap the cell. Use sliders and switches where relevant.
You may want to take a look at http://www.inappsettingskit.com/, we are currently investigating it for the same purpose and it seems to do the job
You can use either a UISlider or a UIPickerView if some of your values have limits.
You can use UISwitch for toggles.
You can also switch the default keyboard for your textfields to be numeric.
Other than that you seem to be on the right track.
Also, sometimes putting a view inside a scrollview makes things seem cooler even if its only one page. The auto bounce on scrollviews is kind of cool.

Switching Between Subviews in iPhone App

So, in an iPhone app I am working on, I've decided that the best way to display all the contents to the user is to have the top part of the screen show some information, and the bottom of the screen show different information. However, the bottom part will change sometimes, so I was working on implementing that.
Another app that does this is the MTGLife app, here are some pictures:

You see that upon hitting a button, the picker switches over and displays the log. Hitting the same button switches them back, with a pretty animation. I would like to do the same thing in my application. I'm not sure the best way to go about it though...
I was thinking that I would make 2 UIViews, and then would simply flip between them, but I want to get some opinions first on how to do this, and then a push in the right direction.
Thank you!
The 2 UIViews is a good approach. By using the UIView animations functions, you can switch between the Log and the Picker with the desired transition.
In the UICatalog sample application (see TransitionViewController), there an example on how to animation two subviews
