iphone - UIPickerView 行颜色

Question

有谁知道如何从 iPhone SDK 更改 UIPickerView 控件中行(或行背景)的颜色？类似于下面的行标题，但我也想更改行的颜色:

- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component;

谢谢。

谢谢诺亚，这正是我所需要的。我想在此处添加代码，以防万一其他人需要(或想要发表评论:)

- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view {

    CGRect imageFrame = CGRectMake(0.0, 0.0, 15, 15);
    UIImageView *label = [[[UIImageView alloc] initWithFrame:imageFrame] **autorelease**];

    if (row == 0)
    {
        label.backgroundColor = [UIColor redColor];
    }
    if (row == 1)
    {
        label.backgroundColor = [UIColor blueColor];
    }
    if (row == 2)
    {
        label.backgroundColor = [UIColor blackColor];
    }   
    return label;
}
