如何以编程方式在按钮上生成事件以进入iPhone的下一页

Question

我已经以编程方式创建了一个按钮，我想触发事件进入下一页，但事件未生成。我该怎么办？

这是代码：

btnSignUp =[UIButton buttonWithType:UIButtonTypeRoundedRect];
btnSignUp.frame =CGRectMake(20,250,280,35);
[btnSignUp setTitle:@"Sign Up" forState:UIControlStateNormal];
[btnSignUp addTarget:self action:@selector(registrationPage:)  
    forControlEvents:UIControlEventAllTouchEvents]; 

    -(void)registrationPage:(id)sender
    {           
    registration =[[RegistrationPage alloc] initWithNibName:@"Registration" bundle:[NSBundle mainBundle]];

        [self.navigationController pushViewController:registration animated:YES];

    }
