Iphone UIpickerview未从UItabbarcontroller设置动画

我向选项卡栏控制器添加了一些viewcontroller，并在viewcontroller中添加了1个文本字段，因此当我单击文本字段时，我调用UIactionsheet。操作表包含2个子部分（1.UIpickerview 2.UItoolbar）。。。我面临一些问题，比如当我加载UIactionsheet时，它工作正常，但我无法选择任何行。。或者不点击dissmiss actionsheet的“完成”按钮。我在这里放了一些代码

在tabbarcontroller.m中

-(void)LoadActionSheet
{
    actionsheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil];
    actionsheet.actionSheetStyle = UIActionSheetStyleDefault;
    actionsheet.delegate = self;

}

in viewcontroller.m

-(void) Comboaction:(NSMutableArray *)DataArray     
{


  EditTabController *obj_tab = [[EditTabController alloc] init];
  [obj_tab LoadActionSheet];

  UIToolbar *Toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(100, obj_tab.actionsheet.frame.origin.y-15, 200, 44)];
  Toolbar.barStyle = UIBarStyleBlack;
  [Toolbar sizeToFit];
  [Toolbar bringSubviewToFront:obj_tab.actionsheet];


  NSMutableArray *barItems = [[NSMutableArray alloc] init];

  UIBarButtonItem *flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
  [barItems addObject:flexSpace];

  UIBarButtonItem *doneBtn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(DissmissPickerview)];
  [barItems addObject:doneBtn];
  [Toolbar setItems:barItems animated:YES];



  [obj_tab.actionsheet setBounds:CGRectMake(0, obj_tab.tbar.frame.origin.y-100, 325,40)];

  picker = [[UIPickerView alloc] init];
  [picker setFrame:CGRectZero];
  picker.tag = 101;
  picker.delegate = self;
  picker.dataSource = self;
  picker.showsSelection

  Indicator = YES;
    [picker setShowsSelectionIndicator:YES];
    [picker setBackgroundColor:[UIColor blackColor]];
   // [picker setFrame:CGRectMake(0,Toolbar.frame.size.height+1, 320, 360)]; 

    [picker bringSubviewToFront:obj_tab.actionsheet];  
    [obj_tab.actionsheet setDelegate:self];
    [obj_tab.actionsheet addSubview:Toolbar];

   [obj_tab.actionsheet addSubview:picker];
   [obj_tab.actionsheet setBounds:CGRectMake(0, 0, 320, 50)];


   [obj_tab.actionsheet showInView:[UIApplication sharedApplication].keyWindow];


}

以及所有pickerview委托方法。。它在简单的viewcontroller中工作良好。但不能在tabbarcontroller中正常工作。

请尝试使用此选项，而不是showInView。[obj_tab.actionSheet showFromTabBar:[self.tabBar控制器tabBar]]；嗨，我试过了，但我仍然面临同样的问题。pickerview未正确设置动画。
