Dismiss the popover view
提问by iOS developer
I have a root view controller in which I load a sub view that contains three buttons. When I touch one of them a popover is shown. The popover contains an image view and a bar with a Done button. I want to dismiss this popover when the Done button is touched. To accomplish this I am using this code
我有一个根视图控制器，我在其中加载了一个包含三个按钮的子视图。当我触摸其中一个时，会显示一个弹出窗口。弹出框包含一个图像视图和一个带有完成按钮的栏。我想在触摸完成按钮时关闭这个弹出窗口。为了实现这一点，我正在使用此代码
- (IBAction)btnDone:(UIBarButtonItem *)sender {
[self.view removeFromSuperview];
[APPDELEGATE.parkDetail. popoverController dismissPopoverAnimated:YES];
// [APPDELEGATE.parkDetail.popoverController dismissPopoverAnimated:YES ];
}
and the popover is presented like this
弹出框是这样呈现的
- (IBAction)btnParkMap:(id)sender {
[popoverController dismissPopoverAnimated:YES];
if ([popoverController isPopoverVisible]) {
[popoverController dismissPopoverAnimated:YES];
} else {
parkMap * v = [[parkMap alloc]initWithNibName:@"parkMap" bundle:nil];
v.contentSizeForViewInPopover = CGSizeMake(350, 300);
popoverController = [[UIPopoverController alloc] initWithContentViewController:v];
CGRect popRect = CGRectMake(self.btnShowPopover.frame.origin.x+330,
self.btnShowPopover.frame.origin.y+170,
self.btnShowPopover.frame.size.width,
self.btnShowPopover.frame.size.height);
[popoverController presentPopoverFromRect:popRect inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
}
}

The PopUpOver can beswitch off the default contextual menu of UIWebView. This is easy because we only need to set the CSS property “-webkit-touch-callout” to “none” for the body element of the web page. We can do this using JavaScript in the UIWebView delegate method “webViewDidFinishLoad:”…
PopUpOver 可以关闭 UIWebView 的默认上下文菜单。这很容易，因为我们只需要将网页的 body 元素的 CSS 属性“-webkit-touch-callout”设置为“none”。我们可以在 UIWebView 委托方法“webViewDidFinishLoad:”中使用 JavaScript...
- (void)webViewDidFinishLoad:(UIWebView *)webView
{
[webView stringByEvaluatingJavaScriptFromString:@"document.body.style.webkitTouchCallout='none';"];
}
