Just set the frame of the UIProgressView in code after it has been initialised. Eg:

<pre><code>UIProgressView *progressView = [[UIProgressView alloc] initWithProgressViewStyle:UIProgressViewStyleDefault];
// progressView's frame will be small/standard height

progressView.frame = CGRectMake(0, 0, 100, 20);
// Now the frame is set to my custom rect.
</code></pre>

This is working for me on iOS 5. I'm using custom trackImage and progressImage though. My code looks like this. Note that I'm adding the progressView to another view and want it to be the same size as the containing view hence setting the frame to self.bounds.

<pre><code>_progressView = [[UIProgressView alloc] initWithProgressViewStyle:UIProgressViewStyleDefault];
_progressView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
_progressView.trackImage = [[UIImage imageNamed:@"search-progress-track"] resizableImageWithCapInsets:UIEdgeInsetsMake(3.0f, 3.0f, 3.0f, 3.0f)];
_progressView.progressImage = [[UIImage imageNamed:@"search-progress"] resizableImageWithCapInsets:UIEdgeInsetsMake(3.0f, 3.0f, 3.0f, 3.0f)];
_progressView.frame = self.bounds;
[_progressView setProgress:0.5];

Select the UIProgressView object in your storyboard or xib, choose Editor > Pin > Height. This will create a height constraint and allow you to change its value in the Attributes Inspector in your left most (Utilizes) panel.

Here is the Solution 

You can use transform, but problem arises that -> when you change orientation of the device, UIProgressView height becomes original one.

So best way to increase UIProgressView height is

<pre><code>yourProgressView.progressImage=[UIImage imageNamed:@"image1.png"];
yourProgressView.trackImage = [UIImage imageNamed:@"image2.png"];
// IMPORTANT: image1/image2 height (in pixel) = height that you want for yourProgressView.
// no need to set other properties of yourProgressView.

For iOS 7 and above, I did the following which (a) works and (b) does not generate a warning:

First add <code>UIProgressView</code> to my View Controller in the storyboard. Then add a Height constraint to the <code>UIProgressView</code> by CTRL+Dragging the <code>UIProgressView</code> to itself. The constraint will be created with a default value of <code>2</code>. Leave that alone.

Now to change the height add an <code>IBOutlet</code> to the <code>UIViewController</code> subclass in code like this:

<pre><code>@property (nonatomic, weak) IBOutlet NSLayoutConstraint *progressHeight;
</code></pre>

Then in your code, probably <code>- viewDidLoad</code>, add:

<pre><code>self.progressHeight.constant = 9;
</code></pre>

This should work out nicely for you.

You can implement a category (new file - category)
and just add the category at the beginning of your class.
It works fine also with iboutlet (nib/storyboard).

The code is just

<pre><code>@interface UIProgressView (heavyView)

@implementation UIProgressView (heavyView)

{
 CGSize newSize = CGSizeMake(size.width, 9);
 return newSize;
}

blocks|key|962282|text|我的建议是在视图控制器的Auto+Layout中放置一个容器视图。确保它是您想要的进度条大小。现在拖动容器内部的进度视图，并将所有边固定到容器的边界。您应该会立即看到进度视图调整大小以适应其容器的边界。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|962283|​|962284|📷|atomic|offset|length|962285|962286|entityMap|0|IMAGE|mutability|IMMUTABLE|imageUrl|https://ask.qcloudimg.com/http-save/yehe-900000/dbc4b28d82fdd9e6c1c2342c95040626.png|imageAlt^0|0|0|0|1|0|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|T|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|U|8|@]|9|@$G|V|H|W|1|X]]|A|$]]|$1|I|3|C|5|6|7|Y|8|@]|9|@]|A|$]]|$1|J|3|-4|5|6|7|Z|8|@]|9|@]|A|$]]]|K|$L|$5|M|N|O|A|$P|Q|R|-4]]]]

My suggestion would be to place a container view on your view controller's view in Auto Layout. Make sure it's the size that you want for your progress bar. Now drag a progress view inside the container and pin all sides to the bounds of the container. You should immediately see the progress view resize to fit the bounds of its container.

blocks|key|1176608|text|我们可以通过创建UIProgressView的子类来创建ProgressView的自定义类，从而设置UIProgressView的高度。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1176609|在斯威夫特，|1176610|public+class+ProgressView:+UIProgressView+{

We can set the height of <code>UIProgressView</code> by creating the custom class of ProgressView by subclassing the <code>UIProgressView</code>.

In Swift,

<pre><code>public class ProgressView: UIProgressView {
 var height: CGFloat = 4.0
 public override func sizeThatFits(_ size: CGSize) -&gt; CGSize {
 return CGSize(width: size.width, height: height) // We can set the required height
 }
}
</code></pre>

blocks|key|962404|text|或者，可以以编程方式实现布局高度。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|962405|private+var+_progress:+UIProgressView!

++++//+...
++++_vstack.translatesAutoresizingMaskIntoConstraints+=+false

++++let+progressHeightAnchor+=+_progress.heightAnchor

Alternately, one could implement the layout height programmatically.
<pre class="lang-swift prettyprint-override"><code>private var _progress: UIProgressView!

 // ...
 _vstack.translatesAutoresizingMaskIntoConstraints = false

 let progressHeightAnchor = _progress.heightAnchor
 .constraint(equalToConstant: 16.0)
 
 NSLayoutConstraint.activate([progressHeightAnchor /* , ... */ ])
</code></pre>

blocks|key|962437|text|我只是在寻找同样的问题，并让它通过子类化UIProgressView和覆盖sizeThatFits方法来工作，工作起来就像一个魔咒。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|962438|class+BigProgressView:+UIProgressView+{

I was just looking for the same problem and got it working with just subclassing <code>UIProgressView</code> and overriding <code>sizeThatFits</code> method, works like a charm.
<pre class="lang-swift prettyprint-override"><code>class BigProgressView: UIProgressView {
 override func sizeThatFits(_ size: CGSize) -&gt; CGSize {
 return CGSize(width: size.width, height: 5)
 }
}
</code></pre>

I am creating <code>UIProgressView</code> from <code>nib</code>. I want to increase its height but it is fixed to 9. For <code>iPad</code> I need to increase its height. How it can be done?

Thanks in advance.
