Question

搜索但似乎无法找到我正在寻找的内容基本上我在一个方法中将值加载到nsmutablearray中然后我想在另一个方法中访问这些值以将它们打印到表中我在app.h中声明了数组

NSMutableArray *clients;

然后在app.m

- (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"]]; 
           }
      }  
}

现在我尝试以另一种方法访问clients数组我在app.h中看到了一些使用extern的建议？某种全局变量？

任何帮助将不胜感激

将app中的clients数组委托给class.declare属性，在app委托类中合成。然后在下面的方法中写这样的。

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

YourApplicationDelegate * delegate = [UIApplication sharedApplication] delegate];

  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"]]; 
           }
      }

}

之后假设你想在另一个类中使用clients数组就是这样。

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

保持值的xcode全局nsmutablearray
