推荐答案

您可以通过在委托类中实现getter和setter来实现.

You can achieve that by implementing getter and setters in the delegate class.

在代理.h文件中

包括UIApplication委托

Include UIApplication delegate

 @interface DevAppDelegate : NSObject <UIApplicationDelegate>

 NSString * currentTitle;

- (void) setCurrentTitle:(NSString *) currentTitle;
- (NSString *) getCurrentTitle; 

在Delegate实现类.m

In Delegate implementation class .m

-(void) setCurrentLink:(NSString *) storydata{
currentLink = storydata;

}

-(NSString *) getCurrentLink{
if ( currentLink == nil ) {
currentLink = @"Display StoryLink";
}
return currentLink;
}

因此，要评估的变量是通过setters方法和要在其中放置字符串的类在currentlink字符串中设置的，只需使用getter方法即可.

So the variable you to assess is set in the currentlink string by setters method and class where you want the string ,just use the getter method.
