：
AppDelegate.h这是我的@interface AppDelegate : UIResponder <UIApplicationDelegate> {
ProductHandlerModel *handler;
}
@property (strong, nonatomic) UIWindow *window;
-(ProductHandlerModel*)getHandler;
@end
：
AppDelegate.m如何从另一个- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
handler = [[ProductHandlerModel alloc]init];
return YES;
}
- (ProductHandlerModel*)getHandler {
return handler;
}
类访问此处理程序对象？

像
一样打电话AppDelegate *delegate = (AppDelegate *) [[UIApplication sharedApplication] delegate];
[delegate getHandler];
或简单地称为
[(AppDelegate *)[[UIApplication sharedApplication] delegate] getHandler];
别忘了导入。
#import "AppDelegate.h"
