NSInvalidArgumentException

我添加了:(id)发件人后,我从这个例程中崩溃,所以我可以确定哪个按钮调用它.当设置为普通的旧toggleView3时,它可以很好地工作.当detailView切换回docView时发生崩溃.

'NSInvalidArgumentException', reason: '*** -[RootViewController toggleView3]: unrecognized selector sent to instance 0x524a00' 2009-04-07 12:29:44.421 eTarot[11405:20b] Stack:

-(IBAction)toggleView3:(id)sender{


    if (detailViewController == nil) {
        [self loadDetailViewController];
    }

    UIView *docView = docViewController.view;
    UIView *detailView = detailViewController.view;

    [UIView beginAnimations:nil context:NULL];
