如何从屏幕底部呈现UIView像UIActionSheet？ [英] How can I present a UIView from the bottom of the screen like a UIActionSheet?

问题描述

我想要一个UIView从屏幕底部向上滑动（并保持中间屏幕）像UIActionSheet。

I'd like a UIView to slide up from the bottom of the screen (and stay mid-screen) like a UIActionSheet. How can I accomplish this?

UPDATE：
我使用以下代码：

UPDATE: I am using the following code:

TestView* test = [[TestView alloc] initWithNibName:@"TestView" bundle:nil];
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.4];
[UIView setAnimationCurve:UIViewAnimationCurveEaseIn];

test.view.center = CGPointMake(160,100);
//test.view.frame = CGRectMake(0, 0, 160, 210);
[[[UIApplication sharedApplication] keyWindow] addSubview:test.view];

[UIView commitAnimations];  

视图似乎是从角落开始动画并出现在角落。如何让它从底部滑动？接近！

The view seems to be animating from the corner and appearing in the corner. How can I make it slide up from the bottom? Getting close!

推荐答案

Matt做了这里，但只是改变了值和方向。

Do what Matt did here, but just change the values and direction. I have code at home to do this from the bottom if you need it later (I'll update this post).

此外，不要忘记取出一些代码，将主视图向下移动（因此，UIView只是像上面一样弹出ActionSheet）

Also, don't forget to take out the bit of code that shifts the main view downward (so instead the UIView just pops over top like an ActionSheet)

已更新为代码：

显示/隐藏一些选项视图：

This is what I use in one of my apps to show/hide a little "options" view:

- (void)toggleOptions:(BOOL)ViewHidden
{
// this method opens/closes the player options view (which sets repeat interval, repeat & delay on/off)

if (ViewHidden == NO)
{
    // delay and move view out of superview
    CGRect optionsFrame = optionsController.view.frame;

    [UIView beginAnimations:nil context:nil];

    optionsFrame.origin.y += optionsFrame.size.height;
    optionsController.view.frame = optionsFrame;

    [UIView commitAnimations];

    [optionsController.view
     performSelector:@selector(removeFromSuperview)
     withObject:nil
     afterDelay:0.5];
    [optionsController
     performSelector:@selector(release)
     withObject:nil
     afterDelay:0.5];
    optionsController = nil;
}
else
{
    optionsController = [[PlayOptionsViewController alloc] init];

    //
    // Position the options at bottom of screen
    //
    CGRect optionsFrame = optionsController.view.frame;
    optionsFrame.origin.x = 0;
    optionsFrame.size.width = 320;
    optionsFrame.origin.y = 423;

    //
    // For the animation, move the view up by its own height.
    //
    optionsFrame.origin.y += optionsFrame.size.height;

    optionsController.view.frame = optionsFrame;
    [window addSubview:optionsController.view];

    [UIView beginAnimations:nil context:nil];

    optionsFrame.origin.y -= optionsFrame.size.height;
    optionsController.view.frame = optionsFrame;

    [UIView commitAnimations];
}
}
