Objective-C：如何作为全局访问字符串变量？ [英] Objective-C: How Can I Access String Variable As a Global?

问题描述

我是iPhone开发的新手。我想在所有类方法中访问一个字符串变量，我想全局访问该字符串。我怎么能这样做？

I am new to iPhone development. I want to access a string variable in all the class methods, and I want to access that string globally. How can I do this?

请帮帮我。

推荐答案

您可以通过在委托类中实现getter和setter来实现这一点。

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

在委托.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实现类中.m

In Delegate implementation class .m

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

}

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

因此，您要评估的变量是通过setters方法在currentlink字符串中设置的你想要字符串的类，只需使用getter方法。

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.
