ios - 在 Swift 中带有标识符的 CustomModalViewController

Question

我正在努力重新创建一个带有“呈现”按钮的简单 VC，以模态转换到具有“关闭”按钮的第二个自定义 VC。这是我试图在 Swift 中重新创建的 Obj C 代码:

- (IBAction)didClickOnPresent:(id)sender {

CustomModalViewController *modalVC = [self.storyboard instantiateViewControllerWithIdentifier:@"customModal"];

modalVC.transitioningDelegate = self;

modalVC.modalPresentationStyle = UIModalPresentationCustom;

[self.navigationController presentViewController:modalVC animated:YES completion:nil];

这是我在 Swift 中的代码:

@IBAction func didClickOnPresent(sender: AnyObject) {

let modalVC = self.storyboard?.instantiateViewControllerWithIdentifier("customModal") as! CustomModalViewController

modalVC.transitioningDelegate = self

modalVC.modalPresentationStyle = UIModalPresentationStyle.Custom

self.navigationController?.presentViewController(modalVC, animated: true, completion: nil)

出于某种原因，模态出现在原始 VC 而不是 2nd VC 中。我检查了网点和标识符。知道我做错了什么吗？

您可能从错误的位置进行演示。试试这个:

self.presentViewController(modalVC, animated: true, completion: nil)
