Question

我是Objective-C的新手，到目前为止我正在使用UIViewController并且我有两个UIPopoverControllers在其中工作但是我希望在我打开另一个时解除PopoverAnimated这里我已经得到的代码对他们来说很远：

-(IBAction)tabBtn1:(id)sender {

CapPhoto *capPhoto = [[CapPhoto alloc] init];
UIPopoverController *pop = [[UIPopoverController alloc] initWithContentViewController:capPhoto];
[pop setDelegate:self];
[pop presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
[pop setPopoverContentSize:CGSizeMake(200, 200)];
[capPhoto release];

}

-(IBAction)tabBtn2:(id)sender {

NewPhoto *newPhoto = [[NewPhoto alloc] init];
UIPopoverController *pop2 = [[UIPopoverController alloc] initWithContentViewController:newPhoto];
[pop2 setDelegate:self];
[pop2 presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
[pop2 setPopoverContentSize:CGSizeMake(200, 200)];
[newPhoto release];


}

所以我已经分配了两个独立的.xib文件（CapPhoto和NewPhoto）作为PopoverControllers，我需要一个在调用另一个时解散。有任何想法吗？干杯！

以下是关于如何在打开另一个时关闭UIPopoverController的解释：

在主viewcontroller.h文件中声明一个UIPopover控制器

@interface viewcontroller: UIViewController {

UIPopoverController *popOne;
UIPopoverController *popTwo;

}
- (IBAction)popOver:(id)sender; 
@Property (nonatomic, retain) UIPopoverController *popOne'
@Property (nonatomic, retain) UIPopoverController *popTwo'

然后在你的视图controller.m文件中：

- (IBAction)popOver:(id)sender {
if ([popOne isPopoverVisible]) {
[popTwo dissmissPopoverAnimated:YES];
//in here is where you add things to your popover

//also note you can find tutorials on popovers this is just code to allow you to dismiss one when opening another. It'll make sense if you've followed a popover tutorial.

}
else {

[popOne dismissPopverAnimated:YES];

}
}

动臂。你做完了！

如何使用BarButtonItem打开另一个UIPopoverController时关闭它？
