保存值的 xcode 全局 nsmutablearray

Question

进行了搜索，但似乎无法准确找到我要找的东西 基本上我用一种方法将值加载到 nsmutablearray 中，然后我想用另一种方法访问这些值以将它们打印到表中 我在 app.h

NSMutableArray *clients;

中声明了该数组，然后在 app.m 中

- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
      [connection release];
      NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
      [responseData release];
      NSArray *results = [responseString JSONValue];
      clients = [[NSMutableArray alloc]init];

      // Loop through each entry and add clients to array
      for (NSDictionary *entry in results)
      {
           if (![clients containsObject:[entry objectForKey:@"client"]]) 
           {   
                [clients addObject:[entry objectForKey:@"client"]]; 
           }
      }  
}

声明了该数组现在我尝试用另一种方法访问客户端数组 我看到一些在 app.h 中使用 extern 的建议？某种全局变量？

任何帮助将不胜感激

谢谢

在应用程序委托类中获取客户端数组。声明属性，在应用程序委托类中合成。然后在下面的方法中这样写。

- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
      [connection release];

YourApplicationDelegate *委托= [UIApplication共享应用]委托];

  NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
  [responseData release];
  NSArray *results = [responseString JSONValue];

      clients = [[NSMutableArray alloc]init];

      // Loop through each entry and add clients to array
      for (NSDictionary *entry in results)
      {
           if (![clients containsObject:[entry objectForKey:@"client"]]) 
           {   
                [delegate.clients addObject:[entry objectForKey:@"client"]]; 
           }
      }

}

之后假设您如果想在另一个类中使用客户端数组，请这样做。

YourApplicationDelegate *delegate = [UIApplication sharedApplication]delegate]; 
NSLog(@"client array is %@",delegate.clients);
