iphone - NSInvalidArgumentException 异常

Question

我在添加 :(id)sender 后遇到此例程的崩溃，因此我可以确定调用它的按钮。当设置为普通的旧 toggleView3 时，它可以完美运行。当 detailView 切换回 docView 时发生崩溃。

'NSInvalidArgumentException'，原因:'*** -[RootViewController toggleView3]:无法识别的选择器发送到实例 0x524a00'

-(IBAction)toggleView3:(id)sender{


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

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

    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:1];
    [UIView setAnimationTransition:([docView superview] ? UIViewAnimationTransitionFlipFromRight : UIViewAnimationTransitionFlipFromLeft) forView:self.view cache:YES];

    if ([docView superview] != nil) {
        [detailViewController viewWillAppear:YES];
        [docViewController viewWillDisappear:YES];
        [docView removeFromSuperview];

        [self.view addSubview:detailView];
        [self.view insertSubview:detailNavigationBar aboveSubview:detailView];
        [docViewController viewDidDisappear:YES];
        [detailViewController viewDidAppear:YES];

    } else {
        [docViewController viewWillAppear:YES];

您正在发送 View toggleView3 选择器的正确名称为 toggleView3: - 即带有colon和crompt。它们可能看起来与您相似，但它们是与 Objective-C 完全不同的方法。
