Question

这里是代码：

<div ng-controller="HomeController">        
    <script type="text/ng-template" id="buttonTemplate.html">
        <button class="btn btn-sm btn-danger" ng-click="cellTemplateScope.doSomething()">Do Something</button>
    </script>

    <tree-grid tree-data="yourTreeData" col-defs="col_defs"></tree-grid>
</div>

- ＆GT;行

将网址替换为： http://s1mp3.r41s223.vcdn.vn/d3f549abeeef07b15efe/2937387453157939420?key=c2WuQChtsmR9yfdz9I-jnw&expires=1480695588&filename=Only%20Love%20-%20Trademark.mp3

- ＆GT;它不起作用;没有任何反应

Answer 1

默认情况下，从iOS 9开始，所有连接都必须为https。如果第二个URL的网站不支持https：//则下载将失败。

我建议您检查从下载中获取的错误代码

Answer 2

如果要使用带有HTTP连接的URL，请在info.plist文件中添加以下内容应用程序传输安全设置和添加子部分允许任意加载并将值设置为YES。

Answer 3

请加入Plist

- (void)deleteImageForButton:(UIButton *)button{
    [self.imageArray removeObjectAtIndex:button.tag];
    [button removeFromSuperview];
    for(long i=button.tag + 1; i<= self.imageArray.count ; i++)
    {
        UIButton *button = (UIButton *)[self.view viewWithTag:i];
        button.tag = button.tag - 1;
        [button setImage:self.imageArray[button.tag] forState:UIControlStateNormal];
    }
}

然后使用Alamofire 4.0 Swift 3.0

使用以下方法，你可以下载任何东西，例如。 PDF
