I am developing an iPhone application. Where in, I want to have UIPickerView as in the image. Is it possible to change the appearance of UIPickerView like this?! Please guide me to do this!! I am creating it without XIB.

或者有没有办法让 UIPickerView 皮肤透明？

推荐答案

我不知道这是否正确但你可以设置你的 UIPickerView 背景图片......我已经完成了一次。

I dont know this is a correct way or not but you can set your UIPickerView background image ... I have done it once.

看到： -

//Make a view to set as background of UIPickerView
UIView * viewForPickerView = [[UIView alloc]initWithFrame:CGRectMake(0.0, 0.0, 320.0, 216.0)];
[viewForPickerView setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"pickerViewBackground.png"]]];

[[[pickerView subviews]objectAtIndex:2] addSubview: viewForPickerView];

//UIPickerView has 8 subviews like, background, rows, container etc.
// hide unnecessary subview

[(UIView*)[[pickerView subviews] objectAtIndex:3] setHidden:YES];
[(UIView*)[[pickerView subviews] objectAtIndex:5] setHidden:YES];
[(UIView*)[[pickerView subviews] objectAtIndex:6] setHidden:YES];
[(UIView*)[[pickerView subviews] objectAtIndex:7] setHidden:YES];
[(UIView*)[[pickerView subviews] objectAtIndex:8] setHidden:YES];

现在只需添加一个 UILabel UIPickerView 的 selectionIndicator ，并使用 标签 作为 selectionIndicator 。
你可以用自己的方式管理它。

And now add a UILabel just on your UIPickerView's selectionIndicator, and use label as a selectionIndicator.you can manage it in your own way.

谢谢！
