您可以通过两种方式分享：

You can share in two ways:

使用属性

示例

.h file

    @interface ABCController : UIViewController
    {
        NSMutableArray *detailArray;
    }
    @property(nonatomic,retain)NSMutableArray *detailArray;

在 .m 文件中

    XYZController *xyzVC = [[XYZController alloc] initWithNibName:@"XYZController" bundle:nil];    
    xyzVC.detailArray = self.detailArray;

    [self.navigationController pushViewCsecondView:xyzVC animated:YES];


    **XYZController.h**

    @interface XYZController : UIViewController
    {
        NSMutableArray *detailArray;
    }

@property(nonatomic,retain)NSMutableArray *detailArray;

使用 NSUserDefaults

Using NSUserDefaults

示例

     [[NSUserDefaults standardUserDefaults] setValue:SongArray forKey:@"songArray"];
     [[NSUserDefaults standardUserDefaults] synchronize];

     NSMutableArray *arr = [[NSUserDefaults standardUserDefaults] valueForKey:@"songArray"];
