iOS：如何在主视图顶部显示小视图？

Question

I'm new here, don't be very hard on me :)

Learning iOS development and trying to display a small view to enter some data to my app, which is using storyboards.

I tried adding it as subview but I can't move it from the top-left corner or make the background to fade. Any advice on how to do this?

Forgot to mention that this is for iPhone.

Thanks

Based on your comment it seems that you don't have a clear understanding of the difference between UIView and UIViewController.

Think of a UIViewController as your screen. Your screen might be showing many different views at once, but they are all part of the UIViewController's view.

Rather then present a new UIViewController (ie screen), you want to do something like this:

//Use a XIB for this, not a storyboard
UIView *newView = [[[NSBundle mainBundle] loadNibNamed:@"addData" owner:self options:nil] lastObject];
[self.view addSubview:newView];

I suggest reading these two guides from Apple until you understand the difference between a UIView and a UIViewController:
