如何使用MKMapView（SDK3.2）中的UIPopoverController解除在iPad上的PopoverAnimated [英] How to dismissPopoverAnimated on iPad with UIPopoverController in MKMapView (SDK3.2)
问题描述
我有一个带注释的MKMapView（也是一个UIPopoverControllerDelegate）。这个MapView在 MKTestMapView.h 文件中有一个@interface中定义的 UIPopoverController * popoverController 和一个 @property （非原子，保留）UIPopoverController * popoverController; 在 @interface 部分之外定义。该控制器在 MKTestMapView.m 文件中 @synthesized ，并在 - （void）dealloc中发布部分。此MapView中的注释具有 rightCalloutAccessoryView s定义如下：
I have a MKMapView (also a UIPopoverControllerDelegate) with Annotations. This MapView has, in the MKTestMapView.h file, a UIPopoverController* popoverController defined in the @interface and a @property (nonatomic, retain) UIPopoverController* popoverController; defined outside of the @interface section. This controller is @synthesized in the MKTestMapView.m file and it is released in the - (void)dealloc section. The Annotations in this MapView have rightCalloutAccessoryViews defined to the following:
- (void)mapView:(MKMapView *)mapView2 annotationView:(MKAnnotationView *)aview calloutAccessoryControlTapped:(UIControl *)control{
...
CGPoint leftTopPoint = [mapView2 convertCoordinate:aview.annotation.coordinate toPointToView:mapView2];
int boxDY=leftTopPoint.y;
int boxDX=leftTopPoint.x;
NSLog(@"\nDX:%d,DY:%d\n",boxDX,boxDY);
popoverController = [[UIPopoverController alloc] initWithContentViewController:controller];
popoverController.delegate = self;
CGSize maximumLabelSize = CGSizeMake(320.0f,600.0f);
popoverController.popoverContentSize = maximumLabelSize;
CGRect rect = CGRectMake(boxDX, boxDY, 320.0f, 600.0f);
[popoverController presentPopoverFromRect:rect inView:self.view permittedArrowDirections:UIPopoverArrowDirectionRight animated:YES];
...
}
现在这里有趣的部分。首先，我不确定我是否需要 maximumLabelSize 和 rect 相同的大小。我是popovercontroller的新手，所以我一直在玩这个...
Now here comes the fun part. First of all, I am not sure if I need maximumLabelSize and the rect to be the same size. I am new to the popovercontroller so I am playing this by ear..
好吧，popover显示。现在解雇它。我可以点击mapView2上的任何地方，然后popover消失......但我需要用户点击视图中的按钮，如果他们改变任何东西。 URGH！
Okay, the popover shows. Now to dismissing it. I can click anywhere on mapView2 and the popover goes away...but I need the user to click a button in the view if they change anything. URGH!
文档显示：
要以编程方式解除弹出窗口，
调用dismissPopoverAnimated：弹出控制器的
方法。
To dismiss a popover programmatically, call the dismissPopoverAnimated: method of the popover controller.
嗯，这是问题：根据定义popoverController如何工作，你点击里面显示的弹出窗口的视图（点击按钮），但必须触发 dismissPopoverAnimated：方法启动这个popover视图的控制器，在我的例子中， MKTestMapView.m 文件中的 popoverController 。
Well, here is the problem: By definition of how the popoverController works, you are clicking inside the view of the displayed popover (to click the button) but have to trigger the dismissPopoverAnimated: method of the controller that launched this popover view, in my case, the popoverController inside the MKTestMapView.m file.
现在，说了这么多，记住， [popoverController release] 直到：
Now, having said all that, remember, [popoverController release] doesn't happen until:
- (void)dealloc {
[popoverController release];
[mapView release];
[super dealloc];
}
所以，我只是在按钮内执行以下操作（凌乱但可能有效） ）：
So, do i just do the following inside the button (messy but may work):
（假设我的弹出视图是一个TableView）在：
(Assuming my popover view is a TableView) In the:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
MKTestMapView * mKTestMapView = [[MKTestMapView alloc] init];
[[mKTestMapView popoverController].dismissPopoverAnimated:YES];
}
这是我的问题：我无法弄清楚做上述事情是否给了我一个引用（如果有这样的话）到屏幕上的现有视图 - 因此视图是该视图的所有者popoverController。如果它很简单
Here is my issue: I cannot figure out whether doing the above gives me a reference (if there is such a thing) to the existing view that is on the screen -- and therefore the view that is the owner of that popoverController. If it is as simple as
[[[self parentView] popoverController].dismissPopoverAnimated:YES];
我会拍自己因为我认为这也不是正确的语法！
I will shoot myself cos I don't think that is the correct syntax either!
这应该很容易......但我迷路了。 （可能只是对我正在学习的许多iPad差异感到沮丧）。
This should be easy...yet I am lost. (probably just frustrated with so many iPad differences that I am learning).
任何人都可以解释更多吗？
Can anyone explain more?
推荐答案
我遇到了同样的问题...我在弹出窗口加载的视图顶部有一个整洁的关闭按钮（X），但它没有用。在我的通用应用程序中，它将作为新视图呈现，以便代码保留。
I had the same problem... I had a neat "close" button (X) in the top of my view loaded by the popover, but it didn't work. In my universal app it will be presented as a new view, so that code should stay.
我现在所做的是将以下内容添加到我的detailedPinView（popover加载的视图）中：
What I did now was that I added the following to my detailedPinView (the view the popover loads):
在详细的PinView.h文件中：
in the detailedPinView.h file:
@interface detailedPinView : UIViewController {
[...]
UIPopoverController *popover;
[...]
}
-(void)setPopover:(UIPopoverController*)aPopover;
在detailedPinView.m文件中：
In the detailedPinView.m file:
- (void)setPopover:(UIPopoverController*)aPopover
{
popover = aPopover;
}
X按钮使用IBAction关闭视图，这就是我在那里做的：
The X button closes the view using an IBAction, this is what I did there:
在详细的PinView.m文件中：
In the detailedPinView.m file:
-(IBAction)releaseDetailedView:(UIButton *)sender
{
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
{
if (popover != nil)
{
[popover dismissPopoverAnimated:YES];
}
else {
NSLog(@"Nothing to dismiss");
}
}
else{
[self.parentViewController dismissModalViewControllerAnimated: YES];
}
}
在加载我的地图和弹出视图的类中我添加了以下代码：
In the class loading the my map and the popover view I added the following code:
[...]
-(void)mapView:(MKMapView *)theMapView annotationView:(MKAnnotationView *)pin calloutAccessoryControlTapped:(UIControl *)control
{
UIViewController *detailController = [[detailedPinView alloc] initWithNibName:@"detailedPinView"
bundle:nil
annotationView:pin];
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
{
UIPopoverController* aPopover = [[UIPopoverController alloc] initWithContentViewController:detailController];
[aPopover setDelegate:self];
[aPopover setPopoverContentSize:CGSizeMake(320, 320) animated:YES];
[detailController setPopover:aPopover];
[detailController release];
[mapView deselectAnnotation:pin.annotation animated:YES];
self.popoverController = aPopover;
[mapView setCenterCoordinate:pin.annotation.coordinate animated:YES];
[self.popoverController presentPopoverFromRect:CGRectMake(382,498,0,0) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
}
else
{
[self presentModalViewController: detailController animated:YES];
}
[detailController release];
}
[...]
我不知道是否是你希望得到的答案，我认为这可能是一个混乱的方式...但是给出时间表这就像一个魅力：）
I don't know if the was the answer you were hoping for, I think it might be a bit of a messy way to do it... but giving the time schedule this worked like a charm :)
