Selecting a file to upload causes mobile Safari to

问题:

I've been experiencing behaviour on, at least my iPhone 6 Plus, when using the <input type="file"> to let the user upload an image.

<div class="add__from-camera">
    <button class="add__from-camera__btn">
        <i class="fa fa-fw fa-camera"></i> Add with Camera
    </button>
    <input class="add__from-camera__input" type="file">
</div>

This rest case results in crashes of the tab about 50% of the time, and in my app about 90% of the time.

I was 'lucky' enough to get all of Safari to crash once when the error happened, and this was part of the log:

Exception Type:  EXC_BAD_ACCESS (SIGSEGV)

It seems to indicate an (overflow?) error in display the little thumbnail preview? Is there a way to prevent Safari from crashing when using file input, or at least don't render the thumbnail preview?

Try this:

<input class="add__from-camera__input" type="file" accept="image/*;capture=camera">
