Ios 未调用类的Setter

我正在尝试实现一个car2go风格的应用程序，你可以点击一个注释视图，然后预订汽车。问题是，当我试图将我想要传递给car对象的segue时，我检查该对象是否执行选择器集vehicle，但是if语句失败，尽管我非常确定它已实现。有人能告诉我为什么吗？这是一个学校项目

#import "MapViewController.h"
#import <MapKit/MapKit.h>
#import <CoreLocation/CoreLocation.h>
#import "Vehicles+Company.h"  
#import "Vehicles+MKAnnotation.h"

-(void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{

if ([segue.identifier isEqualToString:@"reserveCar"]) {
    if ([sender isKindOfClass:[MKAnnotationView class]]) {
        MKAnnotationView *aView = sender;
        if ([aView.annotation isKindOfClass:[Vehicles class]]) {
            Vehicles *vehicle = aView.annotation;
            if ([segue.destinationViewController respondsToSelector:@selector(setVehicle:)]) {
                [segue.destinationViewController performSelector:@selector(setVehicle:) withObject:vehicle];
            }
        }
    }
}

}

很可能

segue.destinationViewController

不是

CompanyVehicleViewController

的实例

在故事板中验证视图控制器的类型是否设置为正确的类。

确认

segue.destinationViewController

确实是

CompanyVehicleViewController

的实例。使用调试器或添加

NSLog

语句。它表示它是UIViewController的一个类，而不是CompanyVehicleViewController，如何修复此问题？应该有一种方法可以更改segue中view controller的类。我发现我没有在故事板中将viewcontroller设置为该类，谢谢！我想给你一个答案，这样我就可以给你分数了

#import <UIKit/UIKit.h>
#import "Vehicles+MKAnnotation.h"
#import "Vehicles.h"
#import "Vehicles+Company.h"


@interface CompanyVehicleViewController : UIViewController

@property (nonatomic,strong) Vehicles *vehicle;

@end

#import "CompanyVehicleViewController.h"

@interface CompanyVehicleViewController ()

@end

@implementation CompanyVehicleViewController

-(void) setVehicle:(Vehicles *)vehicle{
_vehicle = vehicle;
self.title = vehicle.name;
NSLog(@"Vehicle is %@", vehicle);
}

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
    // Custom initialization
}
return self;
 }

- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
 }

@end
