我想从视图控制器的应用程序委托数组中添加对象

I want to add objects in array of app delegate from view controller

在 appdelegate.h 中

in appdelegate.h

@property (nonatomic, retain) NSMutableArray *sharedArray;

在 appdelegate.m 中

in appdelegate.m

@implementation AppDelegate
@synthesize sharedArray;

里面didfinishlaunching

self.sharedArray = [[NSMutableArray alloc] init];

在视图控制器中

@interface ViewController () {

    UIApplication *appDelegate;

viewcontroller

appDelegate = [[UIApplication sharedApplication] delegate];
[appdelegate.sharedArray addObject:array];

推荐答案

更改声明

UIApplication *appDelegate;

到

AppDelegate *appDelegate;

//

self.appDelegate =  (AppDelegate *)[[UIApplication sharedApplication] delegate];

//在上面你应该

#import "AppDelegate.h"
