this is how I've adjusted an UITextView using the interface builder. It is latched showing the blue dashed lines in order to apply the default padding.
And this is how it looks at runtime on an iPhone 5 and 6:
You have to add leading and trailing constraints that would keep the view from resizing to fit its content.
Then, the layout might be still ambiguous. This is indicated by orange color. You can add the missing constrains manually or let Xcode do it for you. Here is how to do it:
I recommend investing around 20-30 minutes in reading any tutorial on auto layout. It's worth it. The concept is very simple and it's easy to understand.
I think you're using the Auto Layout feature. You can check out this by clicking on the root view in the interface builder and watch the autolayout checkmark on the component inspector panel .
If the autolayout is enabled you need to add constraines for your UITextView.

I have previously worked in Windows phone and see that every control in windows phone has an Auto property, meaning occupy the size of the content.
I see that in iOS such a property does not exist. When there are dynamic data to be bound to a UILabel, I always need to calculate the height of the data and then assign to the UILabel. This takes a good amount of time and bit painful. Is not there an Auto property or am I missing anything here?
iOS has AutoLayout which is really helpful, get familiar with it.
Click on the Label
Click on the pin constraints button (little square button)
Add your custom LEFT, RIGHT, TOP margins or LEFT, RIGHT, BOTTOM margins
Click on "Add 3 Constraints"
Set number of Lines to 0 which means as much lines as view needs
Then you probably got warning lines, but you can solve them
Just click on fix constraints button (little triangle button)
Click update frames
UPDATE
Important: the answer to your question is to PUT NUMBER OF LINES TO 0 you can use that UILabel with 0 lines(which is autosizing) with frames and AutoLayout. AutoLayout is just a friendly suggestion that can be helful to setup views. Also put Line Breaking Word Wrap
Here you go also with some useful links for working with AutoLayout. AutoLayout is great because you don't care anymore what size is the screen, what orientation has the device at that moment. You just need to setup everything correctly and everything works amazingly but if your setup is wrong then AutoLayout might become your enemy. So start learning and experiencing right now.
Very good point to Begin learning AutoLayout
If Your are being lazy, start from video tutorial series

You need to familiarize yourself with Auto Layout:
Auto Layout dynamically calculates the size and position of all the
views in your view hierarchy, based on constraints placed on those
views.
Just give top, left and right constraints and make label's numberOfLines to 0. That's it. Label's height will resize automatically.
I'm making an app in which I add people to a list by using a modal VC, that currently has only three text fields.
Problem:
This is what I see in the interface builder, inside my Main.storyboard file:
I'm running Xcode version 6.2 (6C131e) and the app I'm making will be for iPod touch only, so I disabled auto-size classes. I'm expecting those text fields to be at the center of the screen (same distance from text field lateral border to screen edges). Instead I get this on the simulator:
Question:
How can I set an equal distance for both the sides of text fields? Any resource like tutorials, examples, guides are appreciated, because I am a very beginner in iOS programming. If this can be done with interface builder for me is better then programmatically.
As simple as this:
In the Align menu from the bottom of interface builder if you set this constraint to 0 it will be the center of the view
Select First Textfield
Goto Pin-> Uncheck constraints to Margin-> Select Top,Left,right constraints with default value(or change if want ex. 16 left,right,30 top).
For Second and Third Textfield
Goto Pin->Uncheck constraints to Margin->Select Top,Left,right constraints
If you are not using Autolayout then the default Autoresizing property should be
Change the Autoresizing property to this :
Check this question : Any other method to resize views, other than Auto-layout
I just take horizontally as example. You have two ways to make it in the centre.
1. Make leading space equals trailing space.
Make the textfield center horizontally in container view.
I recommend you can study with raywenderlich tutorial.

Everytime I run my iOS application, everything is off-centered. In this screenshot, you can see that the text seems a little off, and the black box is definitely not vertically centered along the page, although the text and box are centered according to the storyboard.

storyboard screenshot
I am guessing that the issue must have something to do with the size settings on the bottom of the storyboard. I am using wCompact and hAny.
Any help would be appreciated so that all this will look centered properly.
This is probably because you don't have your constraints set. You can click on the UIImage or UILabel and go to Editor -> Resolve Auto Layout Issues -> Add Missing Constraints (For All Views) if you want to use Auto Layout. Otherwise, look up some constraint tutorials and you'll have to set them manually. It's not too bad once you get the hang out it!
I have read a lot of SO question about this already but nothing seems to work in my case. Simply when you add a UITableView and you test it and rotate the screen it will keep the width of the portrait orientation.
How can I make it so that it will always fill the screen's width for any screen size?
EDIT : My size inspector
Use the Autosizing feature in Storyboard for your UITableView. How to set it:
1.Select your UITableView.
2.Open the right pane -> Size Inspector:
3.Scroll down to the View section, here you'll see the Autosizing menu:
Don;t forget to disable Autolayout feature:
You're using AutoLayout in your XIB, so the AutoResizingMask stuff isn't your best route to success. You need to set the autolayout constraints on your TableView so that there is a 0 px gap between the leading (left) and trailing (right) sides of the TableView and its superview.
You can see from your screenshot that you already have some constraints in place, but they're probably not correct. I suggest you start by resetting all the existing constraints: I find that's usually best when I've got confused about where I am with constraints.
Select the top level view in your XIB file
Select Editor -> Resolve Auto Layout Issues -> Clear All Constraints in View from the menu
Select your TableView
Select Editor -> Resolve Auto Layout Issues -> Reset to Suggested Constraints from the menu
If that does the trick for you, I'd advise that you spend some time getting familiar with AutoLayout and review the constraints generated: you can select and edit them in the size inspector. This is also a pretty good tutorial.
For custom views, I often add my constraints programmatically as it's really easy to keep track of them - they're much more visible than when they're built in IB. I use a set of categories, provided by another SO user, that you'll find here and they make the code very easy to read and maintain.
when I use old AutosizingMask, I got this
but when switch to new AutoLayout, it seems that I must set an/muti edge of screen, but actually I need none of them.
Why I need this is I want to use just one storyboard to adapt both iphone3.5/4 and ipad,
is there any solution to solve this or achieve my purpose?
thx :)
If I am understanding correctly you want the red square to grow if the container grows.
So for that you would add fixed user constraints to the top, left, bottom and top of a fixed value.
I would recommend using a different Storyboard for the iPad thought because you could preview the changes is Interface Builder.
