我的视图上有许多不同的控制器,我有一些通过代码创建的pickerview,例如:

UIPickerView *picker = [[UIPickerView alloc] initWithFrame:CGRectMake(0, 243, 320, 216)];
switch (sender.tag){
    case 0:
        picker.tag = 0;
        break;
    case 1:
        picker.tag = 1;
        break;
    case 2:
        picker.tag = 2;
        break;
    case 3:
        picker.tag = 3;
        break;
}

picker.delegate=self;
picker.dataSource = self;
picker.showsSelectionIndicator = YES;
[self.view addSubview:picker];

现在我需要使用它的默认设置(viewdidload)。如何使用标签来做到这一点?
