如何在用户做出选择时隐藏UIPickerView

Question

我用以下代码创建了一个自定义UIPickerView

UIPickerView *picker =[[UIPickerView alloc] initWithFrame:CGRectMake(139,50,161,30)];
    picker.delegate=self;
    picker.showsSelectionIndicator=YES;
    picker.hidden=NO;

    [self.view addSubview:picker];

现在我想隐藏pickerView,当用户简单地选择一行时

picker.hidden=YES;

现在:1)如何识别用户的选择,然后隐藏无用的选择器视图？2)我可以在TextField中显示选项吗？用@"选择"？

我正在使用UIPickerView作为TextField的inputView(从而替换屏幕键盘).我使用以下委托来解除视图.

#pragma mark - UIPickerViewDelegate
- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component {
    // Code logic
    [[self view] endEditing:YES];
}
