Warning: “format not a string literal and no format arguments”
I have the following line of code that is in my app that a Developer worked on. I am learning the basics of Objective C and as I was updating the App to be iPhone 5 compatible, I see the following warning (I did not change his code) Format String is not a literal string (potentially insecure). The code is as follows;
我的应用程序中有以下代码行，开发人员正在处理它。我正在学习 Objective C 的基础知识，当我将应用程序更新为与 iPhone 5 兼容时，我看到以下警告（我没有更改他的代码）格式字符串不是文字字符串（可能不安全）。代码如下；
self.progressHud.labelText = [NSString stringWithFormat:message];
I don't know exactly what this means and don't want to upload anything that can either be a security issue or get rejected by Apple. Any and all help is appreciated from you all.
我不知道这究竟意味着什么，也不想上传任何可能是安全问题或被 Apple 拒绝的内容。感谢大家的任何帮助。

Use the following Lines:
使用以下几行：
self.progressHud.labelText = [NSString stringWithFormat:@"%@", message];
In objective C, this line get the values from any format such as int,float etc to display the Label. because UILabel and IBOutlet Elements only display the NSString values.
在目标 C 中，这一行从任何格式（如 int、float 等）中获取值以显示标签。因为 UILabel 和 IBOutlet 元素只显示 NSString 值。
However, if you don't need to create a string with multiple variables, it would be more efficient to simply use:
但是，如果您不需要创建具有多个变量的字符串，那么简单地使用会更有效：
self.progressHud.labelText = message;
