Use Size Classes. It helps to have different settings for different devices.

<img src="https://i.stack.imgur.com/TOEV9.png" alt="enter image description here">The most simple way is create a Outlet of your <code>width</code> and <code>height</code> constraint.

Then dynamically change it in <code>viewDidLoad</code> according to phone.

To check which phone it is u can check the device height like <code>480</code> for iPhone 4S ,<code>568</code>for iPhone 5,5S and etc

<pre><code>@interface ScoreListViewController (){
@property (weak, nonatomic) IBOutlet NSLayoutConstraint *widthConstraint;
@property (weak, nonatomic) IBOutlet NSLayoutConstraint *heightConstraint;

@end



- (void)viewDidLoad {
[super viewDidLoad];
// Set the value according to your requirement
if(4S){
self.heightConstraint.constant=100;
}

 }
</code></pre>

I have written a blog <a href="http://deltaaruna.blogspot.co.uk/2015/04/autolayouting-for-dynamically-changing.html" rel="nofollow">article</a> about autolayouting for dynamically changing layouts. 
For each screen size you can programmatically add the constraints. 
Algorithm 

<ol>
<li>Get the current device size</li>
<li>Get the required constraints according to the device size</li>
<li>Then programmatically add the constraints</li>
</ol>

 
Changing according to orientation

<ul>
<li>Listen to the UIDeviceOrientationDidChangeNotification notifiation</li>
<li>Add new constraints according to the notification</li>
<li>Then call setNeedsUpdateConstraints 
For more info and a example code, look at the blog article and <a href="https://github.com/deltaaruna/AutolayoutTableViewCell" rel="nofollow">this</a> github repo</li>
</ul>

I have a UIView in my super view.I have set it some constraints.Now I want the size of view should be different on different devices.If I set the fix width &amp; height then I get the wrong result.I have tried to user aspect ratio but that make a view too big or too small on multiple devices. 

I want the height &amp; width should increase in equal proportion that it must look same all devices.I want to have flexible height and width of the view.Please tell how to do this?

Here is the image

我在我的超级视图中有一个UIView。我已经设置了一些constraints.Now，我想在不同的devices.If上视图的大小应该不同，我设置了固定的宽度和高度，然后我得到了错误的结果。我尝试使用纵横比，但这使得一个视图在多个设备上太大或太小。我想要的高度和宽度应该增加等比例，它必须看起来相同的所有设备。我想有灵活的高度和宽度的view.Please告诉如何做到这一点？这是图片​提前感谢
