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，您可以在故事板中看到我的观点：！[在此输入图像说明] [1]

修改 * 当我使用此方法时，我的进程终止 *

-(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];

}

Answer 1

试试这个：

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

首先阅读教程是很好的：从其他视图控制器呈现视图控制器 http://developer.apple.com/library/ios/#featuredarticles/ViewControllerPGforiPhoneOS/ModalViewControllers/ModalViewControllers.html

Answer 2

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];
}

Answer 3

要将您的按钮与viewController中的方法相关联，您需要在界面设计器中设置IBOutlet（这是最简单的方法）。如果你仍然希望在另一个视图控制器中，你可以在viewDidLoad方法中设置另一个viewController的属性，这样另一个viewController也有一个对该按钮的引用，尽管远非理想。只有一个viewController应该管理按钮。
