Question

我将一些viewcontroller添加到标签栏控制器，在viewcontroller中我添加1个文本字段，所以当我点击文本字段时，我调用UIactionsheet。动作表包含2个子部分（1. UIpickerview 2. UItoolbar）...我面临一些问题，比如当我加载UIactionsheet它工作正常但我无法选择任何行..或者没有点击完成按钮以解决动作表。我在这里放了一些代码..

tabbarcontroller.m中的

-(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];


}

和所有pickerview委托方法..它在简单的viewcontroller中工作正常。但在tabbarcontroller中无法正常工作..

UIpickerview没有来自UItabbarcontroller的动画
