如何呈现半屏模态视图？

问题描述

我有一个UIViewController，当按下一个按钮时，我想要一个半屏幕视图向上滑动，里面有一个UIPicker。

I have a UIViewController and when a button is pressed, I want a half screen view to slide up with a UIPicker in it.

我在IB中做了一个UIView使用UIPicker和带有完成/取消按钮的UIToolBar。

I made a UIView in IB with the UIPicker along with a UIToolBar with Done/Cancel buttons.

如何才能使这个半视图向上滑动，背景视图仍然显示但是变暗或者不能玩。

How can I make it so that just this half view slides up and the background view is still showing but dimmed or cant be played with.

我到目前为止使用此代码：

I'm using this code so far:

- (void)showModalView
{
    [self.popupView setFrame:CGRectMake(0, self.view.frame.size.height, self.view.frame.size.width, self.view.frame.size.height)];
    [self.view addSubview:self.popupView];

    [UIView animateWithDuration:.2 animations:^{
        [self.popupView setFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
    }];
}
