Не отклоняйте поповер изнутри себя. Создайте протокол, который отправит сообщение своему делегату, чтобы затем отклонить его. Например, ваш контроллер представления поповера может выглядеть следующим образом ..
// MyPopoverViewController.h
@protocol MyPopoverDelegate <NSObject>
-(void)didClickCancelButton;
@end
@interface MyPopoverViewController : UIViewController {
}
@property (nonatomic, assign) id<MyPopoverDelegate> delegate;
-(IBAction)cancelButton;
@end
// MyPopoverViewController.m
#import "MyPopoverViewController.h"
@implementation MyPopoverViewController
@synthesize delegate;
// The designated initializer. Override if you create the controller programmatically and want to perform customization that is not appropriate for viewDidLoad.
/*
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
[super viewDidLoad];
}
*/
-(IBAction)cancelButton {
[self.delegate didClickCancelButton];
}
#pragma mark -
#pragma mark Rotation support
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Overriden to allow any orientation.
return YES;
}
#pragma mark -
#pragma mark Memory Management
- (void)didReceiveMemoryWarning {
// Releases the view if it doesn't have a superview.
[super didReceiveMemoryWarning];
// Release any cached data, images, etc. that aren't in use.
}
- (void)viewDidUnload {
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (void)dealloc {
[super dealloc];
}
@end
И тогда вы могли бы использовать ..
// ClassImplementingPopoverController.h
#import <UIKit/UIKit.h>
#import "MyPopoverViewController.h"
@interface ClassImplementingPopoverController : UIViewController <UIPopoverControllerDelegate, MyPopoverDelegate> {
UIPopoverController *myPopoverController;
}
@property (nonatomic, retain) UIPopoverController *myPopoverController;
@end
// ClassImplementingPopoverController.m
#import "ClassImplementingPopoverController.h"
#import "MyPopoverViewController.h"
@implementation ClassImplementingPopoverController
@synthesize myPopoverController;
#pragma mark -
#pragma mark View lifecycle
- (void)viewDidLoad {
[super viewDidLoad];
}
// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations.
return YES;
}
#pragma mark -
#pragma mark MyPopover delegate
-(void)didClickCancelButton {
if ([myPopoverController isPopoverVisible]) {
[myPopoverController dismissPopoverAnimated:YES];
[myPopoverController release];
}
}
#pragma mark -
#pragma mark UIPopoverController delegate
-(void)popoverControllerDidDismissPopover:(UIPopoverController *)popoverController {
if (popoverController == myPopoverController) {
[myPopoverController release];
}
}
/* Use something like this to create your popover, just make sure you set the delegate to self so you can receive the messages
NSLog(@"Displaying Popover!");
MyPopoverViewController *detailViewController = [[MyPopoverViewController alloc] initWithNibName:@"MyPopoverViewController" bundle:nil];
[detailViewController setDelegate:self];
// Pass the selected object to the new view controller.
myPopoverController = [[UIPopoverController alloc] initWithContentViewController:detailViewController];
[detailViewController release];
myPopoverController.popoverContentSize = CGSizeMake(500.0, 150.0);
[myPopoverController setDelegate:self];
