Question

当我添加时，请将文字写入我的UILabel，

Lorem, Ipsum, is simply, dummy text of, the printing, and typesetting industry.

现在，假设我的UILabel的宽度有限，但行数= 0（无限制），那么它将显示如下文字：

Lorem, Ipsum, is
simply, dummy text
of, the printing,
and typesetting 
industry.

在这里，您可以看到换行是在空白处完成的，现在我希望它们更新，并且我只想在有换行符或逗号（，）时才需要换行符。那么，我该如何实现呢。

我的预期输出是

Lorem, Ipsum,
is simply,
dummy text of,
the printing,
and typesetti
ng industry.

Answer 1

经过测试的解决方案

创建Entry.observe('before save', async (ctx) =>{ try { ctx.instance.image = await Entry.upload(ctx.instance.images[0].src) } catch(error){ return Promise.reject(error) } return Promise.resolve() });和text空字符串

customText

如果以前的字符不是let text = "Lorem, Ipsum, is simply, dummy text of, the printing, and typesetting industry." var customText = ""

，则用空格customText替换不可分隔的空格来填充\u{00a0}

创建标签并将customText指定给其文本

text.characters.enumerated().forEach { (idx, character) in
    let prevChar = text[text.index(text.startIndex, offsetBy: max(0, idx-1))]
    if character == " " && prevChar != "," {
        customText.append("\u{00a0}")
    }
    else {
        customText.append(character)
    }
}

 // "myAwesomeDropzone" is the camelized version of the HTML element's ID
var myDropzone = new Dropzone("#myAwesomeDropzone", {
   /*
    * This step isn't required.
    success: function(file, response) {
        file.previewElement.id = response.id;
    }
   */

});
myDropzone.on('removedfile', function(file) {

    var id = jQuery(file.previewElement).find('.dz-filename span').html();
    //  directly access the removing preview element and get image name to delete it from server.
   // var id = file.previewElement.id;
    $.ajax({
        type: 'POST',
        url: '<?php echo base_url('seller/deleteImagegalleryById'); ?>',
        data: {id: id, '<?php echo $this->security->get_csrf_token_name(); ?>': '<?php echo $this->security->get_csrf_hash(); ?>'},
        dataType: 'html'
    });
    var _ref;
    return (_ref = file.previewElement) != null ? _ref.parentNode.removeChild(file.previewElement) : void 0;
});

现在使用此字符串

只需添加这样的文字。我已经对此进行了测试，在这里您可以使用预期的输出，但不要忘记根据此设置标签高度。

   jQuery(document).ready(function() {  
        var showstate = readCookie('showstate');
            if(showstate == 'shown')
                {
                jQuery("#notice").hide();
                }
            jQuery('#notice .close').click(function(e){
                jQuery("#notice").fadeOut();
                createCookie('showstate', 'shown');
            });
    });

也许你应该继承UILabel，CustomLabel.You应该计算内容和逗号并添加\ n。

从UILabel更改LineBreak角色
