我需要一些帮助才能将数据从AppDelegate传递到另一个控制台，这是一个Table View Controller。在AppDelegate中，我有一个服务器响应，我将其转换为字符串。我想要的是将该字符串传递给另一个控制器（表视图控制器）并将其显示到单元格。
这是我的代码 AppDelegate.m
#import "AppDelegate.h"
#import "ChildListViewController.h"
@interface AppDelegate ()
@end

你可以试试这个，我不确定它是否有用但希望能有所帮助
在AppDelegate.h中：为你想传递的东西添加属性，例如。 @property (strong, nonatomic) NSString *string;
在AppDelegate.m中：为其指定值
在YourVC.m：
#import "AppDelegate.h"
AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
NSString *yourString = [appDelegate string];

您现在在Appdelegate中拥有数据。只需在文件中创建一个对象（适合您的表视图），您需要数据，并且您现在可以在该项目中的任何位置访问您的数据。
AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
NSlog(@"appDelegate.fechedArray==%@",appDelegate.fechedArray);
答案 2 :(得分：0)
在AppDelegate.h中
#define XAppDelegate ((AppDelegate *)[[UIApplication sharedApplication] delegate])
@interface AppDelegate : UIResponder <UIApplicationDelegate>
@end
现在你可以像这样访问你的AppDelegate：
XAppDelegate.something
