Question

在我的应用程序中，在某些视图中，我在底部有一个选择器，tabBar我成功隐藏了tabBar，但问题是分配给TabBar的帧也隐藏了。所以现在选择器显示只有一半可以帮助我摆脱这个问题吗？

Answer 1

使用这种方法：

[actionSheetPicker showFromTabBar:self.tabBarController.tabBar];

我希望这会对你有所帮助。

Answer 2

如果隐藏它，请不要隐藏tabbar，这样会产生很多问题而不是隐藏使用此

[actionSheet showInView:self.tabBarController.tabBar];

Answer 3

您无需隐藏tabbar控制器，只需将操作表添加到tabbarcontroller

[actionSheet showInView:self.tabBarController.view];

Answer 4

不要隐藏标签栏并尝试下面的代码

actionSheet=[[UIActionSheet alloc] init];
    [actionSheet showInView:self.tabBarController.tabBar];
    actionSheet.frame=CGRectMake(0, 100,480 ,232);
    actionSheet.delegate=self;
    picker=[[UIPickerView alloc] initWithFrame:CGRectMake(0, 50,480 ,175)];
    picker.delegate=self;
    picker.showsSelectionIndicator=YES;
    [actionSheet addSubview:picker];
    UIToolbar *toolbar=[[UIToolbar alloc] initWithFrame:CGRectMake(0, 0,480 ,50)];
    toolbar.barStyle =UIBarStyleBlackTranslucent;
    NSMutableArray *ButtonArray=[[NSMutableArray alloc ]init];
    Save=[[UIBarButtonItem alloc ]initWithTitle:@"Done" style:UIBarButtonItemStyleBordered target:self action:@selector(save_pressed)];
    UIBarButtonItem *titleName;
    titleName=[[UIBarButtonItem alloc ] initWithTitle: @"Select Date" style:UIBarButtonItemStylePlain target:nil action:nil];
    UIBarButtonItem *space=[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
    UIBarButtonItem *cancel=[[UIBarButtonItem alloc ]initWithTitle:@"Cancel" style:UIBarButtonItemStyleBordered target:self action:@selector(cancel_pressed)];

    [ButtonArray addObject:cancel];
    [cancel release];
    [ButtonArray addObject:space];
    [ButtonArray addObject:titleName];
    [titleName release];
    [ButtonArray addObject:space];
    [space release];
    [ButtonArray addObject:Save];
    [Save release];
    [toolbar setItems:ButtonArray];
    [ButtonArray release];
    [actionSheet addSubview:toolbar];
    [toolbar release];  
    [actionSheet release];
