ckeditor in ipad safari
Hi,

I have a problem with ckeditor on ipad. I have the editor in a bootstrap modal. all work well on the other browsers, but on ipad safari, when you touch inside the editor, the keyboard does not appear so you cannot write anything in it. If you hit one of the buttons like bold, the keyboard will appear after a while.

this is how I initialise the ckeditor:

CKEDITOR.replace( 'text_to_add', {
    toolbar: [
        { name: 'basicstyles', groups: [ 'basicstyles', 'cleanup' ], items: [ 'Bold', 'Italic', 'Underline', 'Strike'] },
        { name: 'paragraph', groups: [ 'list', 'indent'], items: [ 'NumberedList', 'BulletedList', '-', 'Outdent', 'Indent', '-', 'Blockquote'] },
        { name: 'links', items: [ 'Link', 'Unlink'] },

        { name: 'styles', items: [ 'Styles', 'Format', 'Font', 'FontSize' ] },
        { name: 'colors', items: [ 'TextColor', 'BGColor' ] },
    ],
    enterMode: CKEDITOR.ENTER_BR
});

Do you have any idea on how to fix this issue?

thanks
