[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.0];
[UIView setAnimationTransition:UIViewAnimationTransitionNone forView:[self view] cache:YES];
[view setFrame:CGRectMake(0.0f,300.0f,320.0f,325.0f)];
[UIView commitAnimations];

Correct answer is this for custom picker view but it won’t animate like action sheet. But it creates custom picker view.

items =[[NSArray alloc]initWithObjects:@"Hindi",@"English",nil];
pickerView=[[UIPickerView alloc] initWithFrame:CGRectMake(10,250,350,350)];
pickerView.transform = CGAffineTransformMakeScale(0.75f, 0.75f);
pickerView.delegate = self;
pickerView.dataSource = self;
pickerView.showsSelectionIndicator = YES;
pickerView.backgroundColor = [UIColor clearColor];
[pickerView selectRow:1 inComponent:0 animated:YES];
[self.view addSubview:view]; 


- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView;
{
return 1;
}

- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component;
{
return [items count];   
}

- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
return[items objectAtIndex:row];
}
