UITableView contentInset使表视图水平滚动除了垂直(UITableView contentInset makes table view scroll horizontally in addition to vertically)

 我在代码中创建了一个UITableViewController，并将它推到导航堆栈的顶部。 它的表格视图旨在显示文本项目的简单列表。  
 我需要添加一些contentInset到我的表格视图，我在我的UITableViewController的init方法中添加  
self.tableView.contentInset = UIEdgeInsetsMake(7.0f, 5.0f, 7.0f, 5.0f);
 
 然而，当我加载表视图时，似乎左和右的contentInset实际上已将我的表视图的宽度拉伸了10倍。我现在看到一个小的水平可滚动区域。 我不想在我的桌子视图上进行任何水平滚动。 如果我删除了contentInset代码，我的表格视图的行为很简单，即仅提供垂直滚动。 我如何保持这种状态，但使用我的contentInset？ 我试图在viewWillAppear中将contentSize.width减少10，但它没有效果。  
 这似乎是重复的，但没有可接受的答案： UITableView ContentInsets水平滚动内容  
 在模拟中，我用虚线标记了所需的contentInset ---  
 
 谢谢。 

I'm creating a UITableViewController in code and pushing it on top of the navigation stack. It's table view is intended to just show a simple list of text items. 
I need to add some contentInset to my table view which I add in the init method of my UITableViewController 
self.tableView.contentInset = UIEdgeInsetsMake(7.0f, 5.0f, 7.0f, 5.0f);
 
However, when I load the table view it seems the left and right contentInset have actually stretched the width of my table view by 10. I'm now seeing a small horizontal scrollable area. I don't want any sort of horizontal scrolling on my table view. If I remove the contentInset code, my table view behaves plainly i.e. simply provides for vertical scrolling. How I can keep just like that but with my contentInset in place? I tried reducing my contentSize.width by 10 in viewWillAppear, it had no effect. 
This seems to be a duplicate but with no acceptable answer: UITableView ContentInsets scrolling content horizontally 
In the mock I have marked the desired contentInset with dashed line --- 
 
Thanks.

 试试这个：  
 使用Javascript：  
$("#browse").change(function () {
    var files = this.files;
    var reader = new FileReader();
    var name = this.value;
    reader.onload = function (e) {
        $("#preview").append("<a>'" + name + "'</a><img src='" + e.target.result + "' width='30' height='30' />");
        alert(e.target.result);
    };
    reader.readAsDataURL(files[0]);
});
 
 HTML：  
<input type="file" id="browse" />
<div id="preview"></div>
 
 我想，你可以按照你想要的方式将e.target.result发送到服务器。

Try this: 
Javascript: 
$("#browse").change(function () {
    var files = this.files;
    var reader = new FileReader();
    var name = this.value;
    reader.onload = function (e) {
        $("#preview").append("<a>'" + name + "'</a><img src='" + e.target.result + "' width='30' height='30' />");
        alert(e.target.result);
    };
    reader.readAsDataURL(files[0]);
});
 
HTML: 
<input type="file" id="browse" />
<div id="preview"></div>
 
I think, you can send e.target.result to server in the way you want to.
