刪除UITextView中的UIMenuController

Question

我有用於顯示文章HTML頁面的UIWebView。我使用UILongGesture來顯示UIMenuController。在UIMenuItem在筆記上有一個字段。如果單擊註釋它將顯示UITextView。但是，如果我在UITextView，UIMenuItem顯示longpress。如何隱藏？

- (void)viewDidLoad 
{ 
NSMutableArray *items = [[[UIMenuController sharedMenuController] menuItems] mutableCopy]; 
    if (!items) items = [[NSMutableArray alloc] init]; 

    UIMenuItem *menuItem; 
    menuItem = [[UIMenuItem alloc] initWithTitle:@"BookMark" action:@selector(book:)]; 
    [items addObject:menuItem]; 
    [menuItem release]; 
    menuItem = [[UIMenuItem alloc] initWithTitle:@"Notes" action:@selector(note:)]; 
    [items addObject:menuItem]; 
    [menuItem release]; 

    [[UIMenuController sharedMenuController] setMenuItems:items]; 


    [items release]; 



    UILongPressGestureRecognizer *tap = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(tapTest:)]; 
    [tap setDelegate:self]; 
    [wbCont.scrollView addGestureRecognizer:tap]; 

    wbCont.userInteractionEnabled=YES; 
[self.view addSubview:wbCont]; 


} 

如果使用點擊注：

- (void)note:(id)sender { 

    NSLog(@"Note"); 

    // wbCont.userInteractionEnabled=NO; 


    if ([UIMenuController sharedMenuController]) { 

     [UIMenuController sharedMenuController].menuVisible = NO; 

    } 

    txtview = [[UITextView alloc]initWithFrame:CGRectMake(0,0,320,568)]; 

    txtview.font = [UIFont fontWithName:@"Helvetica" size:12]; 
    txtview.font = [UIFont boldSystemFontOfSize:12]; 
    txtview.backgroundColor = [UIColor whiteColor]; 
    txtview.scrollEnabled = YES; 
    txtview.pagingEnabled = YES; 
    txtview.editable = YES; 
    txtview.tag = mainTag*10000; 



    [self.view addSubview:txtview]; 
} 

Answer 1

UIGestureRecognizer有一個名爲enabled屬性。這應該足以禁用長按：

tap.enabled = NO; 

Answer 2

得到了答案。此代碼適用於我。

- (BOOL) canPerformAction:(SEL)action withSender:(id)sender 
{ 

    if (wbCont.superview != nil && ![txtview isFirstResponder]) { 

if (action == @selector(copy:)) 
{ 

return NO; 


} 
    if (action == @selector(book:)) 
    { 
     return YES; 
    } 
    else if (action == @selector(note:)) 
    { 
     return YES; 
    } 

    }else if(txtview.subviews != nil){ 



     if (action == @selector(copy:)) 
     { 

      return NO; 


     } 
     if (action == @selector(book:)) 
     { 
      return NO; 
     } 
     else if (action == @selector(note:)) 
     { 
      return NO; 
     } 


    } 

    return [super canPerformAction:action withSender:sender]; 


}
