我创建了一个示例选择器视图,它将显示一些细节.使用以下方法设置背景色:

_pickerView.backgroundColor = [UIColor redColor]; 

似乎不起作用.但我希望我能创建一个像下图这样的选择器视图

我试图做的是,整个PickerView背景颜色不应该是白色的,它应该填充UIColor我给的.那可能吗？？怎么做？

我想将UIPickerView中的白色背景更改为我自己的图像.

这可能吗？

此外,我设法让我的UIPickerView水平滚动而不是垂直滚动.现在,我想知道是否有任何方法可以调整拾取器视图的两行之间的间距？

我附上了一张图片来表明我的意思.

这是我的代码:

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.

    arrayDays = [[NSMutableArray alloc] init];
    [arrayDays addObject:@"ONSDAG"];
    [arrayDays addObject:@"TORSDAG"];
    [arrayDays addObject:@"FREDAG"];
    [arrayDays addObject:@"LØRDAG"];

    arrayDates = [[NSMutableArray alloc] init];
    [arrayDates addObject:@"29. JUNI"];
    [arrayDates addObject:@"30. JUNI"];
    [arrayDates addObject:@"1. JULI"];
    [arrayDates addObject:@"2. JULI"];

    pickerViewDay = [[UIPickerView alloc] initWithFrame:CGRectZero];
    [pickerViewDay setDelegate:self];
    [pickerViewDay setShowsSelectionIndicator:NO];
    CGAffineTransform rotate = CGAffineTransformMakeRotation(-M_PI/2);
    rotate = CGAffineTransformScale(rotate, 0.25, 2.0);
    [pickerViewDay setTransform:rotate];
    [pickerViewDay setCenter:CGPointMake(self.view.frame.size.width/2, (pickerViewDay.frame.size.height/2)-3)];
    [self.view addSubview:pickerViewDay];

    // Adding selection …

如何在我的选择器视图中隐藏分隔符.这是截图 .

这是我的自定义UIPickerView的代码.

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

UILabel *label=[[UILabel alloc]init];
label.backgroundColor = [UIColor clearColor];
label.textColor = [UIColor whiteColor];
label.textAlignment=NSTextAlignmentCenter;

switch (component) {
    case 0:
        label.text=[_hourArray objectAtIndex:row];
        label.font = [UIFont fontWithName:@"MYRIADPRO-REGULAR" size:70];
        break;

    case 1:
        label.text=[_minutesArray objectAtIndex:row];
        label.font = [UIFont fontWithName:@"MYRIADPRO-REGULAR" size:70];
        break;

    case 2:
        label.text=[_ampmArray objectAtIndex:row];
        label.font = [UIFont fontWithName:@"MYRIADPRO-REGULAR" size:15];

        break;

    default:
        break;
}
return label;
}

-(NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView {
return 3;
}

请帮帮我.谢谢
