如何以编程方式将我的按钮连接到另一个视图控制器类

这是我的编程按钮的代码

UIBarButtonItem *yearButton= [[UIBarButtonItem alloc] initWithTitle:@"Year" style:UIBarButtonItemStyleBordered    
 target:self action:@selector(year:)];


-(void) year:(id)sender{
    NSLog(@"Year button clicked");

    //I don't know what should I write here to connect my button to UIViewController**
    //when I added this line my process is terminated** 

    [self performSegueWithIdentifier:@"YearView" sender:self]; 
 }

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
    if ([segue.identifier isEqualToString: @"YearView"]){
       [segue.destinationViewController setTitle:@"YearView"];
    }
}

在这里您可以在情节提要中看到我的视图：！[在此处输入图像描述][1]

编辑： *当我使用此方法时，我的进程已终止*

-(void)year:(id)sender{

// [self performSegueWithIdentifier:@"YearView" sender:self]; 
NSLog(@"Year button clicked");
YearView *yearVC = [[YearView alloc] initWithNibName:@"YearView" bundle:nil];

[[self navigationController] pushViewController:yearVC animated:YES];   // [yearVC release];

}

试试这个：

YearView *year = [[YearView alloc] initWithNibName:nil bundle:nil];
[self presentModalViewController:year animated:YES];

UIBarButtonItem *yearButton = [[UIBarButtonItem alloc] initWithTitle:@"Year"style:UIBarButtonItemStyleBordered target:self action:@selector(year:)];
self.navigationItem.rightBarButtonItem = yearButton;

-(void) year:(id)sender {
    NSLog(@"Year button clicked");
    YearViewcontroller *yearVC = [[YearViewcontroller alloc] initWithNibName:@"YearViewcontroller" bundle:nil];
    [self.navigationController  pushViewController:yearVC  animated:YES];
    [yearVC release];
}

要将您的按钮与 viewController 中的方法链接，您需要在界面设计器中设置一个 IBOutlet（这是最简单的方法）。如果您仍然希望在另一个视图控制器中使用它，您可以设置另一个视图控制器的属性，例如在 viewDidLoad 方法中，以便另一个视图控制器也具有对按钮的引用，尽管这远非理想。只有一个 viewController 应该管理该按钮。
