活動視圖的iOS內存泄漏

我剛剛在我的應用程序中發現了內存泄漏，但我不確定如何去修復它。它涉及一個活動視圖，該視圖用於共享從RSS源中查看的當前文章的URL。我不確定泄漏的原因。任何想法或建議？ iPhone Leak iPad Leak 活動視圖的iOS內存泄漏

所討論的方法的iPhone版本是：

- (void) showMenu 
{ 
    NSURL *urlToShare = hackyURL; 
    NSArray *activityItems = @[urlToShare]; 
    TUSafariActivity *activity = [[TUSafariActivity alloc] init]; 

    UIActivityViewController *activityVC = [[UIActivityViewController alloc]initWithActivityItems:activityItems applicationActivities:@[activity]]; 
    activityVC.excludedActivityTypes = @[UIActivityTypeAssignToContact, UIActivityTypePostToWeibo, UIActivityTypeSaveToCameraRoll]; 

    [self presentViewController:activityVC animated:TRUE completion:nil]; 
}

編輯：

__block UIActivityViewController *activityVC = [[UIActivityViewController alloc]initWithActivityItems:activityItems applicationActivities:@[activity]]; 
    activityVC.excludedActivityTypes = @[UIActivityTypeAssignToContact, UIActivityTypePostToWeibo, UIActivityTypeSaveToCameraRoll]; 

    [self presentViewController:activityVC animated:YES completion:^{activityVC.excludedActivityTypes = nil; activityVC = nil;}];

：我通過改變上面的代碼此固定在iPhone泄漏除了使用彈出窗口顯示活動視圖之外，iPad版本基本相同。

- (void)showMenu 
{  
    NSURL *urlToShare = hackyURL; 
    NSArray *activityItems = @[urlToShare]; 
    TUSafariActivity *activity = [[TUSafariActivity alloc] init]; 

    UIActivityViewController *activityVC = [[UIActivityViewController alloc]initWithActivityItems:activityItems applicationActivities:@[activity]]; 
    activityVC.excludedActivityTypes = @[UIActivityTypeAssignToContact, UIActivityTypePostToWeibo, UIActivityTypeSaveToCameraRoll]; 

    if ([popover isPopoverVisible]) 
    { 
     [popover dismissPopoverAnimated:YES]; 
     popover = nil; 
    } 
    else 
    { 
     self.popover = [[UIPopoverController alloc]initWithContentViewController:activityVC]; 
     [self.popover presentPopoverFromBarButtonItem:systemAction permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES]; 
    } 

}

我已經改變了上面的代碼，以這個固定的iPhone泄露：

__block UIActivityViewController *activityVC = [[UIActivityViewController alloc]initWithActivityItems:activityItems applicationActivities:@[activity]]; 
    activityVC.excludedActivityTypes = @[UIActivityTypeAssignToContact, UIActivityTypePostToWeibo, UIActivityTypeSaveToCameraRoll]; 

    [self presentViewController:activityVC animated:YES completion:^{activityVC.excludedActivityTypes = nil; activityVC = nil;}];

，但我無法弄清楚如何修復泄漏了iPad上的酥料餅。

if ([self.popover isPopoverVisible]) 
    { 
     [self.popover dismissPopoverAnimated:YES]; 
     self.popover = nil; 
    } 
    else 
    { 
     self.popover = [[UIPopoverController alloc]initWithContentViewController:activityVC]; 
     [self.popover presentPopoverFromBarButtonItem:systemAction permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES]; 
    }

希望它能解決您的問題。
