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;

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.

Use the following Lines:

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.

However, if you don’t need to create a string with multiple variables, it would be more efficient to simply use:

self.progressHud.labelText = message;
