每次iOS应用程序中出现Wepover时，内存分配都会增加

我的应用程序有一些问题，我目前正在使用WEPopover库（ARCified）创建一些自定义Popover。然而，每次我呈现一个popover及其对应的视图（由一个视图和一个填充了数组的tableview组成）时，工具中的分配都会增加，即使我只是一次又一次地重新添加相同的popover，它也会增加。我遗漏了什么，或者这是正常的行为，请参见下面的代码。我应该改为使表视图变弱还是什么

目标视图控制器.h

#import <UIKit/UIKit.h>
#import "AppDelegate.h"


@interface ThemesPopOverViewController : UIViewController <UITableViewDataSource, UITableViewDelegate>{
    NSArray *themes;
}
@property (nonatomic, retain) UITableView *tableView;
@end

我从以下位置添加popover：

-(void) settingAct:(UIButton *)sender{
    if (!popover) {
        ThemesPopOverViewController *newView = [[ThemesPopOverViewController alloc] initWithNibName:@"SettingPopOverViewController" bundle:[NSBundle mainBundle]];
        self.popover = [[WEPopoverController alloc] initWithContentViewController:newView];
        [self.popover setContainerViewProperties:[self improvedContainerViewProperties]];
        [self.popover setPopoverContentSize:CGSizeMake(128, 360)];
        [self.popover presentPopoverFromRect:CGRectMake(sender.center.x+12, sender.center.y, 0, 20)
                                      inView:self.window.rootViewController.view
                    permittedArrowDirections:(UIPopoverArrowDirectionUp|UIPopoverArrowDirectionDown|
                                              UIPopoverArrowDirectionLeft|UIPopoverArrowDirectionRight)
                                    animated:YES];

        newView = nil;
    }else{
        [self removePop];
    }
}

以及“删除门”中用于删除弹出框的删除方法：

-(void) removePop{

    [self.popover dismissPopoverAnimated:YES];
    self.popover = nil;
}

基线=没有popover，Heapshot1=添加popover，Heapshot2=popover dissmissed，Heapshot3=再次添加相同的popover，Heapshot4=popover dissmissed

在设置sact button~action~方法中，执行如下代码

 if (self.popoverController)
{
[self.popoverController dismissPopoverAnimated:YES];
self.popoverController = nil;
}
else
{
    ThemesPopOverViewController *newView = [[ThemesPopOverViewController alloc] initWithNibName:@"SettingPopOverViewController" bundle:[NSBundle mainBundle]];
    self.popover = [[WEPopoverController alloc] initWithContentViewController:newView];
    [self.popover setContainerViewProperties:[self improvedContainerViewProperties]];
    [self.popover setPopoverContentSize:CGSizeMake(128, 360)];
    [self.popover presentPopoverFromRect:CGRectMake(sender.center.x+12, sender.center.y, 0, 20)
                                  inView:self.window.rootViewController.view
                permittedArrowDirections:(UIPopoverArrowDirectionUp|UIPopoverArrowDirectionDown|
                                          UIPopoverArrowDirectionLeft|UIPopoverArrowDirectionRight)
                                animated:YES];
}

这对我来说很好：）

 if (self.popoverController)
{
[self.popoverController dismissPopoverAnimated:YES];
self.popoverController = nil;
}
else
{
    ThemesPopOverViewController *newView = [[ThemesPopOverViewController alloc] initWithNibName:@"SettingPopOverViewController" bundle:[NSBundle mainBundle]];
    self.popover = [[WEPopoverController alloc] initWithContentViewController:newView];
    [self.popover setContainerViewProperties:[self improvedContainerViewProperties]];
    [self.popover setPopoverContentSize:CGSizeMake(128, 360)];
    [self.popover presentPopoverFromRect:CGRectMake(sender.center.x+12, sender.center.y, 0, 20)
                                  inView:self.window.rootViewController.view
                permittedArrowDirections:(UIPopoverArrowDirectionUp|UIPopoverArrowDirectionDown|
                                          UIPopoverArrowDirectionLeft|UIPopoverArrowDirectionRight)
                                animated:YES];
}
