After you place a View inside Interface Builder and blue lines did appear,

<ul>
<li>click on the Resolve auto layout issues button (second to last button in the bottom right corner; looks like circle between vertical lines) </li>
<li>select the Add missing constraints option</li>
</ul>

The constraints that were "proposed" by by the blue lines should now be automatically added to the view.

Xcode 4 added constraints automatically. 
Xcode 5 only adds constraints if you tell it to.

To add constraints in Xcode 5 you need to explicitly lay them out.

You are only one step away...

<ol>
<li>Turn on auto layout.</li>
<li>Add you element to the view. You will see the blue guidelines.</li>
<li>Add your constraints by holding down CTRL and clicking from the element you added to the one you wish to add a constraint between.</li>
</ol>

e.g. If you want to add a constraint for the width of the element. CTRL-drag from the elements back to itself.

If you want to add a space constraint to the superview then CTRL-drag from the element to its superview in the direction you want to add the constraint.

If you want to add a space constraint between two elements. CTRL-drag from one element to the other.

I've been trying to learn about autolayouts in xcode 5 by watching some youtube videos. On the videos, they say:

<ol>
<li>switch on autolayout (which I've done)</li>
<li>Then while dragging an object around the storyboard you'll see blue guides (which I do).</li>
<li>Then, when letting go mouse the mouse, a constraint which look like the letter 'I' appears. </li>
</ol>

However, this doesn't happen for me - it's like constraints aren't being added? 

Am I doing something wrong? Hope this isn't too vague!

我一直试图通过观看youtube视频来了解xcode 5中的自动收费。在视频中，他们说：打开自动收费表(我已经做了)然后，当你在故事板周围拖动一个物体时，你会看到蓝色的向导(我是这样做的)。然后，当鼠标松开鼠标时，一个看起来像字母“i”的约束出现了。然而，这种情况不会发生在我身上--就像没有添加约束一样？我做错了什么吗...
