如何从另一个viewcontroller关闭UIPopoverController？

Question

我创建了一个UIPopoverController，并在单击setReminder按钮popoverView时正常工作，将它添加到主视图控制器。我想解散popupview，如果我点击保存按钮，我该怎么办？

**mainView.m** 
-(void)btnSetReminderTapped:(id)sender 
{ 
setReminderView =[[setReminder alloc]initWithNibName:@"setReminder" bundle:[NSBundle mainBundle]]; 

setReminderView.delegate = self; 
FPPopoverController *popover = [[FPPopoverController alloc] initWithViewController:setReminderView]; 
popover.tint = FPPopoverDefaultTint; 

if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) 
{ 
    popover.contentSize = CGSizeMake(400,400); 
} 
else { 
    popover.contentSize = CGSizeMake(320, 288); 
} 
popover.arrowDirection = FPPopoverArrowDirectionUp; 

//sender is the UIButton view 
[popover presentPopoverFromView:sender]; 
} 

    ***setReminder.m*** 

- (IBAction) btnSaveTapped:(id) sender 
{ 

}

使用委托，通知上btnSave行动你的主要观点，并在该委托解雇。

@protocol EventDelegate <NSObject> 

- evenSaveButtonClicked; 

@end 

在您的主视图控制器实现它作为

- (void) eventSaveButtonClicked{ 
    [popover dissmissPopoverAnimated:YES]; 
} 

-(void)btnSetReminderTapped:(id)sender 
{ 
setReminderView =[[setReminder alloc]initWithNibName:@"setReminder" bundle:[NSBundle mainBundle]]; 
setReminder.delegate = self; 
setReminderView.delegate = self; 
FPPopoverController *popover = [[FPPopoverController alloc] initWithViewController:setReminderView]; 
popover.tint = FPPopoverDefaultTint; 

if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) 
{ 
    popover.contentSize = CGSizeMake(400,400); 
} 
else { 
    popover.contentSize = CGSizeMake(320, 288); 
} 
popover.arrowDirection = FPPopoverArrowDirectionUp; 

//sender is the UIButton view 
[popover presentPopoverFromView:sender]; 
} 

你必须创建SetReminder类

@interface SetReminder 

@property(nonatomic, unsafe_unretain) id<EventDelegate> delegate 

@end 

（.M）内，在实现文件的委托，你可以依达拉奉它如下

@implementation SetReminder 
@synthesis delegate 

// Your button save code 
- (IBAction) btnSaveTapped:(id) sender 
    { 
     if([delegate respondToSelector:@selector(eventSaveButtonClicked)]){ 
      [delegate eventSaveButtonClicked]; 
     } 
    } 

@end
