if you are not interested in autolayout , go to second option

You have to insert a UITextField into your UIViewController inside the UIStoryboard. Then you need to set the constraints by right clicking from the UITextField to the positions you want to fix it to.

Use following constraints:

• Top Space to Container
• Center Horizontally in Container
• Leading Space to Container
• Trailing Space to Container

Here is an example how I did it:

Like you can see in the screenshot, there are also constraints to the UILabel called Title, Center X and Vertical Spacing. If you have other elements above, you have to position the UITextField relative to these elements.

And always think about:

Insert all elements you want inside your view, then start to fix them with constraints, starting from the first at the top and going down till you prepared all UIControls in your UIView. And use the preview view inside the Assistent Editor ( Alt + cmd + Enter ), and select at the top Preview:

Here you can insert phones you want and every change on constraints inside the UIStoryboard will be displayed here immediately, so you don't have to run your app every time again just to see, something again didn't work:
