在接口中声明字符串并创建一个属性：

In the interface declare the string and make a property:

 @interface MyViewController : UIViewController {


   NSString *string_i_want_to_set;  

 }

 @property (nonatomic, retain) NSString *string_i_want_to_set;

 @end

在实现中合成@implementation之后的字符串MyViewController就像这个：

In the implementation synthesize the string after @implementation MyViewController like this:

 #import "MyViewController.h"


 @implementation MyViewController

 @synthesize string_i_want_to_set;

 // OTHER CODE HERE...

 @end

然后当您分配/初始化视图控制器时，您可以设置如下属性：

Then when you alloc/init the view controller you can set the property like this:

MyViewController *myVC = [[MyViewController alloc] init];
myVC.string_i_want_to_set = @"...."

希望这能为您提供更多细节。

Hope this gives you more detail.
