iPhone iOS Will Not Display Box-Shadow Properly

iPhone iOS will not display box-shadow properly

Try adding -webkit-appearance: none; iOS tends to mess up forms.

Box-shadow not shown on Safari Mobile on iOS 7 (in landscape)

Adding border-radius: 1px fixed the problem:

h1 {
    box-shadow: 0 4px 9px -8px #000000;
    border-radius: 1px;
    color: #D95B43;
    height: 1.2em;
    margin-top: 0;
    font-size: 1.3em;
    padding: 10px;
}

CSS Box Shadow not working on iPhone

If this in a form block, add

-webkit-appearance: none;

iPhones can mess up forms. See here.

Drop-shadow not working properly on iOS Safari

As I was playing with this I think one solution could be to use a box shadow, and apply border-radius that is using vw, for proportionality.

Something like this:

.class {
    box-shadow: 6px 6px 0 #5E7735;
    border-radius: 5vw; /* Or whatever fits the corners of the image used) */
}

It's a workaround but hopefully it can help someone out there!

box-shadow: inset doesn't work in iOS

It looks like this should help your problem.

It seems the main thing, is that you have your blur radius(3rd pixel value) set to 0px.

A known problem with box-shadow and older versions of safari is just that, if you have your blur raduis set to 0px, it won't work.

I hope this helps your problem.

"""Safari 6, iOS 6 and Android 2.3 default browser don't work with a 0px value for "blur-radius".

e.g. -webkit-box-shadow: 5px 1px 0px 1px #f04e29;
doesn't work, but

-webkit-box-shadow: 5px 1px 1px 1px #f04e29
does."""

iOS safari: (-webkit-)box-shadow on input:focus doesn't work

Use -webkit-appearance: none to override the native look:

input[type="text"]{
    -webkit-appearance: none;
    -webkit-box-shadow: 0 0 8px #000000;
    box-shadow: 0 0 8px #000000;
}

Shadow effect is not displaying properly for UIView

Since the views may be resized you should update your shadowPath after resizing because it has a fixed size. Unfortunately this can't be done in an extension, because you need to overwrite layoutSubview(). But you may call addShadow() from viewDidLayoutSubviews() from your view controller again for each text field.

You may also modify your extension to only update the path:

extension UIView {
    func addShadow() {        
        layer.cornerRadius = 8

        layer.shadowColor = UIColor.lightGray.cgColor
        layer.shadowOffset = CGSize(width: 0, height: 1.0)
        layer.shadowRadius = 2.0
        layer.shadowOpacity = 0.5
        layer.masksToBounds = false

        updateShadow()
    }
    func updateShadow() {
        layer.shadowPath = UIBezierPath(roundedRect: self.bounds,cornerRadius:8).cgPath
    }  
}

With this you should call updateShadow() from viewDidLayoutSubviews() for each view with a shadow.

If you use a custom subclass for your text fields you may put the updateShadow() call into layoutSubviews(). So you need not to call it from the view controller.
