我会这样做如下 -

I would do it as follows -

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender 
{
    if ([segue.identifier isEqualToString:@"NextSegue"]) 
    {
        DestinationViewController *dest = [segue destinationViewController];

        dest.myData = self.myData; 
    }
}

在DestinationViewController.h中，你应该创建一个property -

And in the DestinationViewController.h, you should create a property -

#import <UIKit/UIKit.h>

@interface DestinationViewController : UIViewController

@property (nonatomic, strong) NSObject *myData;


@end

此外，请确保合成在DestinationViewController.m的myData的属性 -

And also, make sure to synthesize the myData property in DestinationViewController.m -

@interface DestinationViewController ()

@end

@implementation DestinationViewController

@synthesize myData = _myData;

// other methods here

@end
