You can getPicker using this 

-(void)getValuePicker
{
    ViewForValuePicker = [[UIView alloc]initWithFrame:CGRectMake(0, 219, 320, 266)];

    UIToolbar *toolBar = [[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, 320, 44)];
    toolBar.barStyle = UIBarStyleBlackOpaque;

    UIBarButtonItem *btn = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(doneBtnPressToGetValue)];

    [toolBar setItems:[NSArray arrayWithObject:btn]];
    [ViewForValuePicker addSubview:toolBar];


    valuePicker = [[UIPickerView alloc] initWithFrame:CGRectMake(0, 44, 320, 216)];
    valuePicker.delegate=self;
    valuePicker.dataSource=self;
    valuePicker.showsSelectionIndicator=YES;

    [ViewForValuePicker addSubview:valuePicker];

    [appDelegate.window addSubview:ViewForValuePicker];
}

And its Delegete Method 

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

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

- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component;
{
    NSMutableArray *ary = [[NSMutableArray alloc] initWithArray:pickerValueAry];
    id str=[ary objectAtIndex:row];
    return str;
}

- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{    
    NSLog(@"selectedRowInPicker >> %d",row);
}
