在view1中单击按钮时，将数据从View1传递到View2

Question

大家好我是iOS编程新手。当在视图中点击按钮时，我需要将数据从一个视图控制器传递到第二个视图控制器。数据是以字典格式从Web服务获取的，我的问题是如何在数据格式化时解析数据。以下是我将字典作为响应时使用的代码。

我该怎么做才能解析并传递数组？ TIA

- (IBAction)btnListClicked:(id)sender 
{
    ListVC *list = [[ListVC alloc]initWithNibName:@"ListVC" bundle:nil];
    list.clientID= [detailsdict objectForKey:@"clientid"];
    list.custID= [detailsdict objectForKey:@"custid"];

    //detailsdict is NSMutableDictionary
    [self.navigationController pushViewController:list animated:YES];
}

第二个视图控制器模态文件。

#import "View2Controller.h"

@interface View2Controller ()
@property (weak, nonatomic) IBOutlet UILabel *textLabel;

@end

@implementation View2Controller

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    for (id object in self.array) {
        // do something with object
        NSLog(@"%@", object);
    }
    self.textLabel.text = self.array.lastObject;
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

/*
#pragma mark - Navigation

// In a storyboard-based application, you will often want to do a little preparation before navigation
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    // Get the new view controller using [segue destinationViewController].
    // Pass the selected object to the new view controller.
}
*/

@end

在标题中声明您的数组。

#import <UIKit/UIKit.h>

@interface View2Controller : UIViewController

@property NSArray *array;

@end

这是主视图控制器。

#import "ViewController.h"
#import "View2Controller.h"

@interface ViewController ()
@property NSArray *array;
@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    self.array = [NSArray arrayWithObjects:@"test",@"string2", nil];
}


- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (IBAction)btnListClicked:(UIButton *)sender {
    [self performSegueWithIdentifier:@"passData" sender:sender];
}
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    if ([[segue identifier] isEqualToString:@"passData"]) {
        View2Controller *vc = [segue destinationViewController];
        vc.array = self.array;
    }
}
@end
