使用xib的presentModalViewController工作，你如何使用Storyboard做同样的事情？

Question

我可以使用xib来实现这一点，但如何使用Storyboard实现相同目的？我相信我需要使用prepareForSegue，但不知道如何实现它。这是我的代码：

- (void)buttonTouched:(id)sender {
// When picture is touched, open a viewcontroller with the image
PFObject *theObject = (PFObject *)[allImages objectAtIndex:[sender tag]];
PFFile *theImage = [theObject objectForKey:@"imageFile"];

NSData *imageData;
imageData = [theImage getData];
UIImage *selectedPhoto = [UIImage imageWithData:imageData];
PhotoDetailViewController *pdvc = [[PhotoDetailViewController alloc] init];

pdvc.selectedImage = selectedPhoto;
[self presentModalViewController:pdvc animated:YES];

}

Answer 1

要手动创建在故事板中定义的viewcontroller，您必须为其指定标识符

viewController：

[self.storyBoard instantiateViewControllerWithIdentifier:(NSString *)indentifier];
[self.storyBoard instantiateInitialViewController];

将从故事板中返回一个viewcontroller
