ios - 找不到实例方法 '-presentViewController:animated'

Question

我对此还很陌生，所以请多多包涵。我的代码中还有 2 个错误需要修复。在这两种情况下都找不到我的实例方法:

-(IBAction)goFlipSide {
    NSLog(@"goFlipSide has been called:");
    FlipsideViewController *controller = [[FlipsideViewController alloc] initWithNibName:@"FlipsideViewController" bundle:nil];

    controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
    [self presentViewController:controller animated:YES];

    [controller release];
}

- (void)flipsideViewControllerDidFinish:(FlipsideViewController *)controller {
    [self dismissViewControllerAnimated:YES];

    //This method gets fired when the user clicks done on the modal FlipsideViewController.  This is different
    //than the viewWillAppear.
    self.navigationController.navigationBarHidden = TRUE;
    /*
    if (self.goViewSuccess == TRUE) {
        //if the goViewSuccess boolean is set to YES - then we can load the load the goViewController
        NSLog(@"goViewSuccess is YES");
        [self loadGoViewController];
    }
    */
}

两个未找到的实例方法是:presentViewController: 和 dismissViewControllerAnimated:。

Answer 1

self 是什么类？这些方法只能在 UIViewController 上找到。完整的选择器是:

• presentViewController:animated:completion:
• dismissViewControllerAnimated:completion:

尝试添加完成 block 参数。
